D = V • t    ...    displacement = velocity • time 
d = [(s – 4) ⁄ (s² – 9s + 20)] • [(s – 5) ⁄ 4]    ...    rearrange terms 
d = (s – 4) • (s – 5)   ⁄   [4(s² – 9s + 20)]    ...    factor denominator 
d = (s – 4) • (s – 5)   ⁄   [4(s – 4) • (s – 5)] 
d = ¼ mile

Part A:

Derrick is incorrect.
A yard is equivalent to 3 feet.
Thus, 20 yards will be equivalent to 60 feet.

The width is 20 yard and 2 feet. It's the same as 60 feet and 2 feet, or 62 feet. Thus, Derrick is incorrect.

Part B:

Let's calculate the area of the parking lot.

We know the width is 62 feet from part A.
The length is 30 yards, or 90 feet.

Multiply the length and width to get the area in square feet.

90 \times 62=5580

The parking lot has an area of 5580 square foot.
It costs 2 dollars per square foot to repave the parking lot. Multiply the area by 2 dollars.

5580 \times 2=11160

It will cost $11,160 to repave the whole parking lot.

Need help with this question about amplitude
lesantik [10]

Step-by-step explanation:

the amplitude is the height of the wave.

like with sound - the further away you are, the lower the volume of the sound (as the sound volume is the indicator of the amplitude of a sound wave, or the brightness of a light is the indicator of the amplitude of a light wave).

the same for any other type of wave (like the seismic wave of an earthquake).

so, the larger the distance, normally the smaller the amplitude.
