continuously. How much would Alang need to invest, to the nearest dollar, for the
value of the account to reach $113,000 in 5 years?

Answer: yes, 1/3, 1/3x

Step-by-step explanation:

Does x vary directly with y?

This basically means is this a linear function and the answer is yes it is.

What is the constant of variation?

The constant of variation is 1/3 because you have to multiply each x value by 1/3 to get the y value

What is the function rule?

y = 1/3x

The graph of the function f(x) = x² + 7x + 10 is attached.

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line. The fixed point is called the focus of the parabola, and the fixed line is called the directrix. The general equation of a parabola is -

y = a(x - h)² + k

We have the following equation of a quadratic equation representing parabola as -

f(x) = x² + 7x + 10

Refer to the graph of the function f(x) attached. It can be seen that it is a parabola opening upwards.

Therefore, the graph of the function f(x) attached.

Linda starts the month with $15 in debt. Each hour, she makes 2.5 dollars. How many hours will it take for Linda to get out of debt?

A situation that can be represented by the expression 2.5x - 15 is given below.

Let's consider a situation where you are tracking the amount of money you earn from selling handmade crafts. In this scenario, the expression 2.5x - 15 can represent your net earnings after deducting the initial investment and expenses.

Suppose you invest a certain amount of money in materials and supplies to create your crafts. The variable x represents the number of crafts you sell. Each craft generates a profit of $2.50. Therefore, the term 2.5x represents the total profit you earn from selling x crafts.

However, running a business incurs expenses. In this case, the expression -15 represents $15, which is the total expense or cost associated with producing and selling your crafts.

So, 2.5x - 15 calculates your net earnings after subtracting the expenses from the profit. It provides you with a measure of how much money you've made after covering the costs.

By plugging in different values for x, you can evaluate the expression to determine your earnings for various levels of craft sales, allowing you to analyze your profitability and make informed decisions regarding your business.

The equivalent of (h+h)(2) of the function h(x) = 5x - 6 is 5[5(2) - 6] -6 which is option B

A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

This means that if the object x is in the set of inputs (called the domain) then a function f will map the object x to exactly one object f(x) in the set of possible outputs (called the codomain).

h(x) = 5x - 6

(h + h)(x) = h(x) in x. This means put the function in h(x)

so x = 5x - 6

so (h + h)(x) = 5(5x-6) -6

if x = 2,

we have (h + h)(2) = 5[5(2) -6] -6

In conclusion the expression  5[5(2) -6] -6 is equivalent to (h+h)(2)

Applying the two-tangent theorem, the perimeter of the polygon = 70 cm.

To find the perimeter of a polygon, sum all the side lengths of the polygon all together.

If two tangent segment of a circle are drawn to meet at a point outside the circle, the two-tangent theorem says they are congruent together, that is, they have equal length.

Applying the two-tangent theorem, the following side lengths that are missing as labelled in the diagram attached below are:

a = 13 cm

b = 9 cm

c = 5 cm

d = 8 cm

Therefore:

Perimeter of the polygon = 13 + a + b + 9 + 5 + c + d + 8

Plug in the values

Perimeter of the polygon = 13 + 13 + 9 + 9 + 5 + 5 + 8 + 8 = 70 cm.

Answer:30

Step-by-step explanation:

30 is the smallest number that has three different prime factors.

The total number of sandwiches they have in all on Sunday is 375 sandwiches.

The amount earned by the cafe if each sandwich cost $4.50 is $1,687.5

Total percentage of ham and turkey sandwiches = 35% + 25%

= 60%

So,

225 = 60% of x

225 = 0.60 × x

225 = 0.60x

divide both sides by 0.60

x = 225/0.60

x = 375

Hence,

Total number of sandwiches = 375

If the cafe sells all the sandwiches at $4.50 each

The total money earned by the cafe = cost of each sandwich × total number of sandwiches

= $4.50 × 375

= $1,687.5

Therefore, the total sandwiches sold in the cafe on Sunday is 375 sandwiches.

What is the five-number summary?

When conducting descriptive analyses or conducting an initial analysis of a sizable data set, a five-number summary is particularly helpful. The maximum and minimum values in the data set, the lower and upper quartiles, and the median make up a summary's five values.

Given, the five-number summary of Country A:

92, 110, 120, 160, 240

Then, we get

Minimum value = 92, First quartile = 110, Median = 120, Third quartile=160,

Maximum value = 240

Between 110 and 240 pounds, data lies from the First quartile to Maximum value which represents 75% of the data.

The rectangle that has side lengths of 5 units and 6 units is (b) the rectangle that has a perimeter of 22 units

The complete question is added at the end of this solution

From the complete question, we have the following parameters that can be used in our computation:

Side lengths = 5 units and 6 units

These side lengths can be represented as

Length = 5 units

Width = 6 units

The area of a rectangle is calculated as

Area = Length * Width

Substitute the known values in the above equation, so, we have the following representation

Area = 5 units * 6 units

Area = 30 square units

The perimeter of a rectangle is calculated as

Perimeter = 2 * (Length + Width)

Substitute the known values in the above equation, so, we have the following representation

Perimeter = 2 * (5 units + 6 units)

Perimeter = 22 units

Answer:

Triangle PQR is a right triangle. First we have to find the length of each side of the triangle. This can be done using the points provided, along with the Pythagorean theorem, which is a^2+b^2=c^2. PR^2 = (7- -2)^2+(3-5)^2 = 85 => PR = sqrt(85) QR^2 = (7- -1)^2+(3-1)^2 = 68 => QR = sqrt(68) QP^2 = (1-5)^2+(-1 - -2)^2 =17 => QP = sqrt(17) Now that we have the sides of the triangle, we can put them into the Pythagorean theorem again to see that it works out: (Sqrt(17))^2 + (sqrt(68))^2 = (sqrt(85))^2 17 + 68 = 85 85 = 85 Since the Pythagorean theorem works for right triangles, the triangle is indeed a right triangle.

a) The population of the confidence interval is given as follows: The temperature all days for that summer.

b) The point estimate of the interval is of: 80 degrees Fahrenheit.

c) The margin of error of the interval is of: 8 degrees Fahrenheit.

A confidence interval for a population parameter is built taking a sample of this population.

Then, the interval for the population mean is given as the sample mean plus/minus the margin of error.

The sample in this problem is given as follows:

The temperature for 10 days of summer.

Hence the population is of:

The temperature all days for that summer.

The interval in this problem is given as follows:

(72, 88).

The point estimate is the mean of the bounds, hence:

Point estimate = (72 + 88)/2 = 80.

The margin of error is half the difference of the two bounds, hence:

Margin of error = (88 - 72)/2 = 8.
