Answers

Answer: C

Step-by-step explanation:

Answer: D

Step-by-step explanation:

1.88 in the equation is the rate of change.

rate of change means, "the speed at which a variable changes over a specific period of time."

L = the length of his femur. every time the femur grows an inch, the height also increases according to the equation.

an example is when the femur is 19 inches.

H = 1.88(19) + 32.01

H = 67.73

The height of the man is 67.72 inches if his femur was 19 inches.

pls help!!!!!!!!!!11

Answers

Answer: A

Step-by-step explanation: Every hour the temperature goes down 2 degrees and the h wouldn't go on the 32! Good luck! :D

Answer:

C. t = –4h + 21

Step-by-step explanation:

We know that when h = 0, t = 21°F. Replacing h = 0 in equation A and D we get:

t = 21h + 4

t = 21(0) + 4

t = 4

t = –21h + 4

t = –21(0) + 4

t = 4

So, none of them are correct.

The temperature drops 4 degrees every hour, this means that for h = 1 then t = 21 - 4 = 17. Replacing h = 1 in equation B and C we get:

t = 4h + 21

t = 4(1) + 21

t = 25

t = –4h + 21

t = –4(1) + 21

t = 17

In consequence, C is the correct option.

State the domain: x^2 +16x+64

Answers

Answer:

All real numbers

Step-by-step explanation:

x² + 16x + 64 is a parabola that opens up, when graphed.

This means it will have a U shape that will infinitely extend outwards in both directions, across the x axis.

So, the domain will include all real numbers.

The dimensions of an iron box are 9ft * 4.4ft* 2.5ft. What is the cost of the iron sheet used to make the box, if the cost of the sheet is Rs 6 per Square Foot?

Answers

Answer:

Rs 877.2

Step-by-step explanation:

The dimensions of an iron box are 9ft * 4.4ft* 2.5ft. What is the cost of the iron sheet used to make the box, if the cost of the sheet is Rs 6 per Square Foot?

The iron box is shaped as a rectangular prism

The formula for the surface area of a rectangular prism is given as:

S = 2(lw + lh + wh)

L = Length = 9ft

W = Width = 4.4ft

H = Height = 2.5 ft

Hence:

Surface area = 2[(9 × 4.4) + (9 × 2.5) +(4.4 × 2.5)]

Surface area = 2[(39.6) + (22.5) + (11)]

Surface area = 2[73.1]

Surface area = 146.2 ft²

From the question:

The cost of the sheet is Rs 6 per Square Foot

1 ft² = Rs 6

146.2 ft² = x

Cross Multiply

x = 146.2 × Rs 6

x = Rs 877.2

The cost of the iron sheet used to make the box is Rs 877.2

Suri makes $15 per hour and gets a weekly bonus of $25. Juan makes $14 per hour and gets a weekly bonus of $50. Is it possible for Suri and Juan to make the same amount of wages, y, by working the same number of hours, x, in one week?

Answers

Answer:

25 hours per week

Step-by-step explanation:

Step one:

given data

Suri makes $15 per hour and gets a weekly bonus of $25

Juan makes $14 per hour and gets a weekly bonus of $50.

Let the number of hours worked be x

and let the total earned be y

For Surl

The expression for the total is

y= 25+15x-----------1

For Juan

The expression for the total is

y= 50+14x-----------2

Step two:

Equate the two expressions we have

25+15x=50+14x

collect like terms we have

25-50= 14x-15x

-25= -x

x= 25

Yes its is possible that they earned the same amount if they work for 25 hours

9. A box of cereal is packaged and sold at a local
grocery store. The volume of the cereal in the
box is 80% of the total volume of the box. The
base of the box measures 10 inches by 3 inches.
The height of the box is 1 foot. What is the
volume of the cereal in the box, measured in
cubic inches?

Answers

Answer:

288 Cubic Inches

Step-by-step explanation:

Assuming the cereal takes up 80% of the total volume of the box, you would take 80% of the total volume.

First, do Base x Width x Height for the volume of the box.

10 inches x 3 inches x 1 foot (1 foot is 12 inches)

10 x 3 x 12 = 360

Now, take 80% of 360 cubic inches.

80% is 0.8 times a number

0.8 x 360 = 288

288 Cubic Inches

Step-by-step explanation:

f(x) = a * b^x

We have the following information:

f(0) = a * b^(0) = 15. => a * 1 = 15, a = 15.

f(1) = a * b^(1) = 9. => a * b = 9, (15) * b = 9, b = 0.6.

Hence f(x) = 15 * 0.6^x.
