Using the compound interest formula the percentage of growth per year (APY), to the nearest hundredth of a percent is 2.82%.
What is Compound Interest?
The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest. It differs from simple interest in that the principal is not taken into account when determining the interest for the subsequent period with simple interest. Compound interest is commonly abbreviated C.I. in mathematics.
To calculate the value of the account after t years, we can use the formula for compound interest -
[tex]A = P(1 + \frac{r}{n} )^{(nt)}[/tex]
where -
A is the final amount
P is the principal amount
r is the annual interest rate (as a decimal)
n is the number of times the interest is compounded per year
t is the number of years
In this case, P = 2800, r = 0.028 (since the APR is 2.8%), n = 365 (since the interest is compounded daily), and we want to find A as a function of t.
So the function that represents the value of the account after t years is -
[tex]f(t) = 2800 \times \big(1 + \frac{0.028}{365} \big)^{(365 \times t)}[/tex]
We can simplify this function by using the fact that 0.028/365 is a constant.
Let's call this constant "k" -
k = 0.028/365
Then we can rewrite the function as -
[tex]f(t) = 2800 \times (1 + k)^{(365 \times t)}[/tex]
Rounding all coefficients to four decimal places, the final function is -
[tex]f(t) = 2800 \times (1 + 0.000077)^{(365 \times t)}[/tex]
To calculate the annual percentage yield (APY), we can use the formula -
[tex]APY = (1 + \frac{r}{n} )^{(n-1)}[/tex]
where r is the annual interest rate and n is the number of times the interest is compounded per year.
In this case, r = 0.028 and n = 365. So the APY is -
[tex]APY = (1 + 0.028/365)^{365 - 1} = 0.02824...[/tex]
Rounding to the nearest hundredth of a percent, the APY is 2.82%.
Therefore, the APY value is obtained as 2.82%.

Okay, I really need some help with my math questions
1. At a local ballgame the hamburgers sold for 2.50 each and the cheeseburgers sold for 2.75 each. there were 131 total burgers sold for a total value of 342. how many of each kind of burger were sold?
2. Bradford bought a total of 20 medium and large bags of chips. If he spent $53 and bought 6 more large bags of chips as medium bags of chips, how many large and medium bags of chips did he buy? HELP: chips; large-$3, medium-$2, and small-$1
please help I will make you brainliest! Answer the questions fully and show how did you do it.
Answer: Let's use the following system of equations to represent the given information:
h + c = 131 (the total number of burgers sold is 131)
2.5h + 2.75c = 342 (the total value of the burgers sold is $342)
where h represents the number of hamburgers sold and c represents the number of cheeseburgers sold.
We can use the first equation to solve for one of the variables in terms of the other:
h + c = 131
h = 131 - c
Substituting this into the second equation, we can solve for c:
2.5h + 2.75c = 342
2.5(131-c) + 2.75c = 342
327.5 - 2.5c + 2.75c = 342
0.25c = 14.5
c = 58
So, 58 cheeseburgers were sold. We can use the first equation to find the number of hamburgers sold:
h + c = 131
h + 58 = 131
h = 73
Therefore, 73 hamburgers were sold.
Let x be the number of medium bags of chips that Bradford bought. Then, he bought 20 - x large bags of chips.
According to the problem, the total cost of the chips was $53. We can set up an equation for the total cost in terms of x:
diff
2x + 3(20-x+6) = 53
2x + 54 - 3x + 18 = 53
-x = -19
x = 19
So, Bradford bought 19 medium bags of chips and 20 - 19 = 1 large bag of chips.
Enjoy!

Consider two natural numbers n,k and p where 0≤k≤p≤n a. Prove that:
P(n+1,k)=P(n,k)+kP(n,k−1) b. Prove that: C(n,k)C(n−k,p−k)=C(p,k)C(n,p)
`C(p,k) * C(n-p,k)`
a. Proof: We will apply the same method we used in formula (1) in our class notes on this question. For this purpose, we choose a set containing `n + 1` elements. It contains all elements of the set of `n` elements and another element `y` that has not been included in the set of `n` elements.Let the number of sets of `n` elements that contain `k` particular elements `a` be `P(n, k)`. To count the number of sets of `n + 1` elements that contain `k` elements, we use the concept of permutations with repetition, such as -{n + 1} can be placed in any of the `k` places of the k-element subsets of `{1, 2,...,n}`, or it can be one of the remaining `n-k+1` elements in each of the `P(n,k)` sets that contain `k` elements.Let us use `A` to denote the set of sets of `n` elements that do not contain the element `y` and `B` to denote the set of sets of `n` elements that contain the element `y`. Then, `P(n+1,k)=|A|+|B|=P(n,k)+(n−k+1)P(n,k−1)`.b. Proof: To count the number of `k` element subsets from a set of `n` elements, we use `C(n, k)`.Let us consider two sets, `A` and `B`, where `|A|=n-k` and `|B|=p-k`. We want to choose `k` elements from these two sets such that the number of subsets we get from `A` is `x` and the number of subsets we get from `B` is `y`. In the set `A`, we select `x` elements by choosing `k-x` elements from the remaining `n-k` elements. Similarly, in the set `B`, we select `y` elements by choosing `k-y` elements from the remaining `p-k` elements.Thus, the total number of ways of choosing `k` elements from `A` and `B` is given by `C(n-k, x) * C(p-k, y)`. The total number of ways of choosing `k` elements from `n` elements is given by `C(n, k)`. Therefore, the total number of ways of choosing `k` elements from `n` elements such that `x` elements are chosen from `A` and `y` elements are chosen from `B` is `C(n-k, x) * C(p-k, y) * C(n, k)`.To get the total number of ways of choosing `k` elements from `n` elements such that `k` elements are chosen from `A` and `p-k` elements are chosen from `B`, we must sum over all possible values of `x` and `y`. Thus, the total number of ways of choosing `k` elements from `n` elements such that `k` elements are chosen from `A` and `p-k` elements are chosen from `B` is given by: `C(p,k) * C(n-p,k)` which is the required result.

Step-by-step explanation: ?
Answer:
Step-by-step explanation:
x+y=17
x-y = 7
From equation 2, x = 7 + y
put this in equation 1.
(7+y) + y = 17
7+2y = 17
2y = 10
y = 5.
We said that x = 7+y
thus, x = 7 + 5
x = 12.
2x+2y=36
2(x+y) = 36
Thus, x + y = 18.
x+y = 18
x-y=6 using elimination (literally simplifying this)
2x = 24 (y-y=0. ELIMINATED!)
x = 12
When x = 12,
x+y=18
12+y=18
y=6.
3x = y
x + y = 20
From 1, y = 3x.
x + (3x) = 20
4x = 20
x = 5.
when x = 5,
y = 3x
y = 3(5)
y = 15.
x+y = -4
xy = -21
from 1, x = -4-y
=> y(-4-y)= -21
-y²-4y = -21
Therefore,
y² + 4y -21 = 0
y= 3 or -7.
When y = 3,
x + 3 = -4
x= -7.
When y = -7,
x + (-7) = -4
x-7=-4
x = 3.

A proportional connection exists when two values may be expressed as y = kx, where k is a constant. To discover which ordered pairings have a proportionate connection with (0.2, 0.3).
We must find a value of k for each pair that makes this equation true. Let us begin with option A: (1.2, 2.3). If we wish to represent this combination as y = kx, we must discover the value of k that results in 2.3 = k. (1.2). When we solve for k, we get: k = 2.3 / 1.2 ≈ 1.92 As a result, (1.2, 2.3) does not have a proportionate connection with (0.2, 0.3) since the value of k is different for both couples. This procedure can be repeated for each of the others. options. Option B: (2.7, 4.3) yields: k = 4.3 / 2.7 ≈ 1.59 Option C: (3.2, 4.8) yields: k = 4.8 / 3.2 = 1.5 Option D: (3.5, 5.3) yields: k = 5.3 / 3.5 ≈ 1.51 Option E: (5.2, 7.8) yields: k = 7.8 / 5.2 = 1.5 As a result, alternatives C and E are proportional to (0.2, 0.3) since they can be represented in the form y = kx with the same k value. k = 1.5 in both situations.

What is a polynomial?A polynomial is a mathematical expression in which the power of the unknown is greater than or equal to 2.
Since we have the polynomial (5x² + x - 7)(x - 4) - (2x³ + 5x² - 6) and we want it expressed as a polynomial in the form ax³ + bx² + cx + d, to find the value of b, we proceeda s follows.
(5x² + x - 7)(x - 4) - (2x³ + 5x² - 6)
Expanding the brackets, we have that
(5x² + x - 7)(x - 4) - (2x³ +5x² - 6) = 5x³ - 20x² + x² - 4x - 7x + 28 - (2x³ + 5x² - 6)
= 5x³ - 20x² + x² - 4x - 7x + 28 - 2x³ - 5x² + 6
Collecting like terms, we have

= 3x³ - 24x² - 11x + 34
So, comparing 3x³ - 24x² - 11x + 34 with ax³ + bx² + cx + d, we have that

ABCD is a parallelogram and CE stands on AD, DF stands on AB. If AD = 20 metre, CE = 8 metre, AB = 16 metre, find DF
In the parallelogram ABCD the value of DF is 13.33 metres or DF = 40/3 metres (rounded to two decimal places).
In the parallelogram ABCD, we can draw a diagonal AC that splits the parallelogram into two congruent triangles, namely, △ABC and △ADC.
Let x be the length of DF. We can use similar triangles to find x.
Notice that △BCE and △DFE are similar triangles, since they share the same angle at E and the angles at B and D are congruent due to opposite angles in a parallelogram. Therefore, we can write the following proportion:
BC/CE = DF/FE
Substituting the given values, we have:
16/8 = x/(20-x)
Simplifying this equation, we get:
2 = x/(20-x)
2(20-x) = x
40 - 2x = x
3x = 40
x = 40/3
Therefore, DF = 40/3 meters or 13.33 meters (rounded to two decimal places).

The caterpillar touches 15 points with two integer coordinates, including the start point (-3, -4) and the end point (25, 38).
What is co-ordinate geometry ?
Coordinate geometry is a branch of mathematics that deals with the study of geometry using the principles of algebra. In coordinate geometry, geometric figures are represented using algebraic equations and analyzed using techniques from algebra and calculus.
The caterpillar moves from (-3, -4) to (25, 38) in a straight line. We can find the equation of the line passing through these two points using the slope-intercept form of the equation of a line:
y - (-4) = (38 - (-4))/(25 - (-3)) * (x - (-3))
y + 4 = 42/28 * (x + 3)
y = 3/2 * x + 19
The caterpillar touches a point with two integer coordinates whenever x and y are both integers. To find these points, we can substitute integer values for x and solve for y. Since the slope of the line is 3/2, every time x increases by 2, y increases by 3.
Starting from x = -3, we can list the integer values of x that the caterpillar touches:
-3, -1, 1, 3, 5, ..., 25
For each value of x, we can compute the corresponding value of y using the equation of the line:
y = 3/2 * x + 1
For example, when x = -3, y = 3/2 * (-3) + 19 = 14.5, which is not an integer. When x = -1, y = 3/2 * (-1) + 19 = 17.5, which is also not an integer. However, when x = 1, y = 3/2 * 1 + 19 = 20, which is an integer. Similarly, we can find the integer values of y for all the other values of x.
Therefore, the caterpillar touches 15 points with two integer coordinates, including the start point (-3, -4) and the end point (25, 38).

What is the resulting costant when (2 - 4/3) is subtracted from (-3/5 plus 5/3)
The resulting constant is 2/5 when (2-4/3) is subtracted from (-3/5 plus 5/3).
What is subtraction?Mathematical subtraction includes calculating the difference between two numbers. It is the inverse of addition and is denoted by the symbol "-". When we subtract one number from another, we are essentially finding out how much smaller the second number is than the first number.
According to question:We can simplify the expressions inside the parentheses first:
2 - 4/3 = 6/3 - 4/3 = 2/3
-3/5 + 5/3 = -9/15 + 25/15 = 16/15
So the expression (-3/5 + 5/3) - (2 - 4/3) becomes:
(16/15) - (2/3)
To subtract these fractions, we need to find a common denominator, which is the least common multiple of 15 and 3, which is 15. Then we can rewrite both fractions with this denominator:
(16/15) - (2/3) = (16/15) - (10/15)
Now we can subtract the numerators and keep the denominator:
(16/15) - (10/15) = 6/15 = 2/5

(1 point) A tank contains 60 kg of salt and 2000 L of water. Pure water enters a tank at the rate 8 L/min. The solution is mixed and drains from the tank at the rate 4 L/min. (a) What is the amount of salt in the tank initially
The initial amount of salt in the tank is 60 kg, calculated using the formula M = ρV, where M is the mass of the salt, ρ is the density of the salt, and V is the volume of the tank.
Initially, the tank contains 60 kg of salt and 2000 liters of water. The amount of salt in the tank can be calculated using the formula M=ρV, where M is the mass of the salt, ρ is the density of the salt, and V is the volume of the tank. The density of salt is 2270 kg/m3. Assuming the tank has a constant volume, the mass of the salt in the tank is 60 kg.
The amount of salt in the tank changes due to the addition of pure water and mixing of the solution. The amount of salt in the tank at any given time can be calculated using the formula M=ρV, where M is the mass of the salt, ρ is the density of the salt, and V is the volume of the tank. The rate at which the salt is added to the tank is equal to the rate at which the salt-water solution is drained from the tank.
Therefore, the rate of change of the mass of the salt in the tank is equal to 8 liters/minute of pure water entering the tank minus 4 liters/minute of salt-water solution draining from the tank. Thus, the amount of salt in the tank initially is 60 kg.

Determine the quantity of fuel that was utilized by the water tanker in March
The quantity of fuel that was utilized by the water in March is 230.4 liters.
Fuel capacity of the tanker = 460 liters
Fuel consumption rate = 5 km/ℓ
Total distance covered per full tank = fuel capacity * fuel consumption rate = 460 x 5 = 2,300 km
Number of full tanks required to make one round trip = distance per round trip / total distance covered per full tank = 18/2300
=0.0078
Number of round trips made in March 2022 = 1/0.0078 x 2
= 64.1
Total distance covered = number of round trips * distance per round trip
= 64 x 18
= 1,152 km
Therefore, the total distance covered by the water tanker = 1,152 km
Quantity of fuel utilized = total distance covered / fuel consumption rate
= 1152/5
= 230.4 liters.
Therefore, The quantity of fuel that was utilized by the water in March is 230.4 liters.

A fish tank contains 90 litres of water, rounded to 1 significant figure.
30 litres of water, rounded to 1 significant figure, are removed from the
tank.
Work out the upper bound of the volume of water left in the fish tank.
Give your answer in litres.
The upper bound of the volume of water left in the fish tank is 60 liters.
What exactly is a litre of water?33.81 fluid ounces make up one litre (US).
One litre of water would fill about one-fourth of a gallon water bottle. Also, you should be aware that there are two different kinds of ounces used globally to measure water volume: (1 litre = 33.814 US ounces).
The maximum allowable mistake can be added to the actual value to determine the upper bound of the amount of water still in the fish tank.
The maximum error for 90 litres, rounded to one significant figure, is half of the value of the last significant figure, or 5. Hence, the actual value of 90 litres might be either 85 or 95.
The largest potential inaccuracy for 30 litres, rounded to one significant figure, is likewise 5. Hence, the actual value of 30 litres might be 25 or 35.
We subtract the lower bound of the withdrawn volume from the higher bound of the original volume to determine the upper bound of the volume of water still present in the tank.
The upper bound of the volume of water left in the fish tank can be found by adding the half of the absolute uncertainty to the measured value of 60 liters (90 - 30):
Upper bound = 60 + 0.5 x 1 = 60.5 liters (rounded to 1 significant figure)
Therefore, the upper bound of the volume of water left in the fish tank is 60 liters.

The dimensions of a rectangle are 14 centimeters by 48 centimeters. Find, in centimeters, the length of the diagonal of the rectangle
We can use the Pythagorean theorem to find the length of the diagonal of the rectangle. The Pythagorean theorem states that in a right triangle with legs of length a and b and hypotenuse of length c, we have:
a^2 + b^2 = c^2
In this case, the rectangle has dimensions of 14 centimeters by 48 centimeters, so we can let the length and width of the rectangle be the legs of a right triangle, and the diagonal be the hypotenuse. Then:
a = 14 cm b = 48 cm c = ?
We can plug these values into the Pythagorean theorem and solve for c:
14^2 + 48^2 = c^2 196 + 2304 = c^2 2500 = c^2 c = sqrt(2500) c = 50
Therefore, the length of the diagonal of the rectangle is 50 centimeters.
Answer:
50 cm
Step-by-step explanation:
the equation is d=sqrt(w^2+l^2)
so you get sqrt(14^2+48^2) which equals 50.
