Mathematics
1 answer:
GalinKa [24]3 years ago
8 0

Answer:

C

Step-by-step explanation:

The first one (0,7) tells you that when x isn't there, the amount of money is 7.

That means that the y intercept is 7.

When x = 1 the total is 15

Money saved = ax + 7

15 = a*1 + 7                         Subtract 7

15-7 = a + 7-7

a = 8

The equation is f(x)  = 8x + 7

The table shows your height on a water slide at various time intervals
Allushta [10]

1. The average rate of change in a riders height between 1 and 3 seconds -30 ft/s

2. The average rate of change in a riders height between 0 and 5 seconds -24 ft/s

3. Another word for rate of change in this situation is speed

<h3>What is speed? </h3>

Speed is defined as the rate of change of the distance travelled with time. Mathematically, it can be expressed as:

Speed = distance / time

With the above idea, we can obtain the answers to the question given above.

<h3>1. How to determine the rate of change between 1 and 3 seconds</h3>
  • Change in height = 30 - 90 = -60 ft
  • Change in time = 3 - 1 = 2 s
  • Rate of change =?

Rate = Change in height / change in time

Rate = -60 / 2

Rate = -30 ft/s

<h3>2. How to determine the rate of change between 0 and 5 seconds</h3>
  • Change in height = 0 - 120 = -120 ft
  • Change in time = 5 - 0 = 5 s
  • Rate of change =?

Rate = Change in height / change in time

Rate = -120 / 5

Rate = -24 ft/s

<h3>3. what is another word for rate of change?</h3>

From the definition of speed given above, we can say that: another word for rate of change is speed

Find the surface area of a right square pyramid with base edge length<br> 2 feet and height 5 feet.
zhenek [66]

Answer:

24.4 sq. ft.

Step-by-step explanation:

Area of a right square pyramid is:

A = a^2 + 2(a)*square root of ((a^2/4) + b^2)

A = 4 + 4 (square root of ((4/4) + 25) = 4 + 4* square root of 26

A = 4 + 4*5.099

A = 4 + 20.396

A = 24.396 sq ft.
