A car leaving a stop sign accelerates constantly from a speed of 0 feet per second to reach a speed of 44 feet per second. The d

Nikolay [14]

Answer:

Option C.

Step-by-step explanation:

The distance of the car from the stop sign, d , in feet, at time t , in seconds, can be found using the equation

$d=1.1t^2$

The average rate of change of a function f(x) on [a,b] is

$m=\dfrac{f(b)-f(a)}{b-a}$

We need to find the average speed of the car, in feet per second, between t=2 and t=5.

At t=2,

$d=1.1(2)^2=4.4$

At t=5,

$d=1.1(5)^2=27.5$

The average speed of the car, in feet per second, between t=2 and t=5 is

$\text{Average speed}=\dfrac{d(5)-d(2)}{5-2}$

$\text{Average speed}=\dfrac{27.5-4.4}{3}$

$\text{Average speed}=\dfrac{23.1}{3}$

$\text{Average speed}=7.7$

The average speed of the car, in feet per second, between t=2 and t=5 is 7.7 feet per second.

Therefore, the correct option is C.

In comparison to 1/3 where would 2/6 be located an on a number line

marta [7]

Answer:

If you simplify 2/6, you get 1/3 by dividing the numerator and denominator by 2.

Therefore, 1/3 and 2/6 would be the same point on the number line.
