4. Bradford hopped into his Ford Mustang GT to rush to Diana and tell her how fantastic his students did on the End of course exam. His Mustang

can go from 0 to 60 mph in a brief 4.7 seconds. Bradford accelerated to

top speed quickly and then maintained a speed of 60 mph until he

arrived at Diane's office.

See explanation and image attached

Step-by-step explanation:

Acceleration refers to the rate of change of speed with time. We can see that between 0 and 4.7 seconds he accelerated quickly . That means that the rate of change of speed with time was greatest between 0 and 4.7 seconds.

A graph of the motion is shown in the image attached. We can see that he maintained a constant speed after 4.7 seconds.

step-by-step explanation:

quartic functions has x = –1 and x = –2 as its only two real zeroes:

f(x) = a(x+2)(x+1)   a: real number

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
