Suppose that when your friend was born, your friend's parents deposited $5000 in an account paying 5.7% interest compounded quarterly. What will the account balance be after 19 years?
Answer:
$337,807.321.
Step-by-step explanation:
every year has 4 quarters, so 19 years = 76 quarters, so it compounds 76 times = (1+5.7%)^76. so punch into the calculator 1.057 then the "xy"button, then 76, it'll spit out 67.56146111 number. then hit times 5000. which is $337,807.321. power of compounding. More than a quarter million $$$.

It is possible to have a rational function where the denominator can have no zeroes and thus the function itself will have no singularity. Such a function will have no vertical asymptotes.
What is a rational function?A rational function is one that can be written as a polynomial divided by a polynomial. Since polynomials are defined everywhere, the domain of a rational function is the set of all numbers except the zeros of the denominator. Example 1. f(x) = x / (x - 3). The denominator has only one zero, x = 3.
Given, In a rational function, R(x): = P(x)/Q(x)
p/q is a form of rational function.
q is not zero since divisor cannot be 0.
If we divide any function by 0 the operation is considered as undefined.
A rational function has at most one horizontal or oblique asymptote, and possibly many vertical asymptotes.
First, factor both the numerator and the denominator. Then, cancel out any common factors. A common factor does not give rise to a vertical asymptote, but it does create a hole if the zero of the common factor is real. Next, find the zeros for all of the remaining factors in the denominator after canceling out the common factors. For each zero in the denominator, there will be a vertical asymptote at that zero.
Therefore, The simples example I can give you for such a rational function would the f(X) = X, defined over the real numbers.

what is the volume of this triangle ( im confused and need help)
Answer:
672
Step-by-step explanation:
1. Multiply the length, width, and height of the triangle.
14 x 12 x 8 = 1,344
2. Divide by 2.
1,344/2 = 672
Answer:
672 Feet^3
Step-by-step explanation:
Volume of a triangle = 1/2 (B)(H)(L)
B = base
H = height
L = length
I see you've found the numbers for B, H, and L so great start.
B = 12
H = 8
L = 14
So now its just plug and play
(12)(8) = 96
(96)(14) = 1344
And lastly (1/2)(1344) = 672 cubic feet

how would I solve this
please help me understand the problem
[tex] - 4 = 4 \\ - 6 = 6[/tex]
I don't understand how to solve with the system if equations
Answer: (0, -1)
Step-by-step explanation:
Hello! One method you can use to solve a system of equations is the elimination method. Here are the steps to use the elimination method in this equation:
-4y + x = 4 -4y - (-6y) = -4y + 6y = 2y, x -x = 0, 4 - 6 = -2
- (-6y + x = 6)
_________
2y = -2
__ __
2 2
y = -1
You now know that y = -1 for both lines to intersect. Let's now find x using the substitution method.
Use the equation -4y + x = 4. Substitute -1 for y in the equation.
-4(-1) + x = 4
4 + x = 4
-4 = -4
x = 0.
You now know that x = 0 and y = -1. Coordinate pairs are represented as (x, y). Substitute 0 in for x and -1 in for y. Your answer is (0, -1).
if there is a 50% probability that bond a will default next year and 30% probability that bond b will default what is the range of probability that at least one will default
So the range of probability that at least one bond will default next year is between 0% and 80%.
The probability that at least one of two events will occur is the sum of the probability of each event minus the probability that both events will occur. In this case, the probability that at least one bond will default is:
P(A or B) = P(A) + P(B) - P(A and B)
Where P(A) is the probability of bond A defaulting (50%), P(B) is the probability of bond B defaulting (30%), and P(A and B) is the probability that both bonds will default (which we don't know).
So the range of probability that at least one bond will default is:
P(A or B) = 50% + 30% - P(A and B)
The maximum possible probability of both bonds defaulting is (0.5 * 0.3) = 15% and the minimum possible probability of both bonds defaulting is 0%. Therefore, the range of probability that at least one bond will default is:
P(A or B) = 80% - 0% = 80%
So the range of probability that at least one bond will default next year is between 0% and 80%.
It's important to note that the above formula and the range of probability is based on the assumption of independence, i.e the events of Bond A defaulting and Bond B defaulting are independent and don't affect each other.

las edades de los hermanos de una familia son 3, 4, 6, 9, 15, 17. La varianza de las edades de esta poblacion es
The variance of the ages of this population is equal to 28.33.
How to calculate the mean age?Mathematically, the mean for the ages of these siblings (mean age) would be calculated by using this formula:
Mean = [F(x)]/n
Total age, F(x) = 3 + 4 + 6 + 9 + 15 + 17
Total age, F(x) = 54.
Therefore, the mean age is given by:
Mean age = [F(x)]/n
Mean age = 54/6
Mean age = 9
Next, we would calculate the standard deviation by using this formula:
Standard deviation, SD = √(1/n × ∑(xi - u₁)²)
Standard deviation, SD = √(1/6 × [(3 - 9)² + (4 - 9)² + (6 - 9)² + (9 - 9)² + (15 - 9)² + (17 - 9)])
Standard deviation, SD = √(1/6 × [36 + 25 + 9 + 0 + 36 + 64])
Standard deviation, SD = √170/6.
Standard deviation, SD = 5.32
In Statistics, the standard deviation of a data set is the square root of the variance and this is given by this mathematical expression:
Variance = δ²
Variance = 5.32²
Variance = 28.33.

A triangle has two sides of length 18.1 and 16.6. What compound inequality describes the possible lengths for the third side, x?
Answer:
1.5 < x < 34.7
Step-by-step explanation:
You want a compound inequality describing possible lengths (x) for the third side of a triangle with sides 18.1 and 16.6.
Triangle inequalityThe shortest side cannot be any shorter than the difference of the two known sides:
18.1 -16.6 = 1.5
The longest side cannot be any longer than the sum of the two known sides:
18.1 +16.6 = 34.7
The possible lengths of the third side are given by ...
1.5 < x < 34.7

Additional comment
If the third side is exactly equal to the sum or the difference, then the "triangle" looks like a line segment. It has zero area. That possibility is usually disallowed. If you want to allow it, then change < to ≤ in the inequality.

One angle measures 18°, and another angle measures (6d − 6)°. If the angles are complementary, what is the value of d?
Answer:
By definition, if two angles are complementary, they both will add up to 90 degrees. Knowing this add 18 and (6d-6) together to equal 90.
18+(6d-6)=90
Subtract 18 from both sides, then add 6. This leaves you with 6d equal to 78. Divide by 6 to get 13.
(6d-6)=72
6d=78
d=13 degrees
Make sure of your answer. You know that d is 13, so plug it back into the equation to see if it equals 90 degrees.

In Geometry, triangles are the type of polygons, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.
Based on the sides of a triangle, a triangle is classified into 3 types, namely:
Scalene Triangle – All the sides are of different measures.
Isosceles Triangle – Two sides of a triangle are of the same measure and the remaining side has a different measure.
Equilateral Triangle – All the 3 sides of a triangle are of the same measure.
Based on the angles of a triangle, a triangle is classified into 3 types, namely:
Acute Angle Triangle – All the angles of a triangle are less than 90°.
Obtuse Angle Triangle – One of the angles of a triangle is greater than 90°.
Right Angle Triangle – One of the angles of a triangle is equal to 90°.
Now,
As sum of all angles of triangles=180°
90+2x+33+5x-34=180

The price per package of cup = $3.50
The total money needed for cup = 12× $3.50 = $42
The amount of napkins needed = 10 package
The price per package of napkins = $4.25
The total money needed for napkins = 10×4.25 = $42.5

Jill has launched a model rocket from the Earth with an upward speed of 80 feet per second. The path of the rocket can be modeled by the equation h(t) = -16t2 + 80t. What is the range?
The range is 5 feet
The path of the rocket can be modeled by the equation
h(t) = -16t² + 80t
We know that the range of a projectile is nothing but the horizontal distance the projectile travels from the time it is launched to the time it comes back down to the same height at which it is launched.
To find the horizontal distance we find the distance between the points on the horizontal axis.
i.e., to find the value of t for which h(t) = 0
Let us assume that the value of equation h(t) = 0
h(t) = 0
-16t² + 80t = 0
t(-16t + 80) = 0
t = 0 OR -16t + 80 = 0
t = 0 OR -16t = -80
t = 0 OR t = 5
So, the range would be,
R = 5 - 0
R = 5 feet
