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.

Engineers measure angles in gradients, which are smaller than degrees. The table shows the conversion of some angle measures in

loris [4]

The table showing the conversion of angle measure in degrees to angles in gradients is attached below.

In order to find the slope we divide the difference of two y-coordinates (or dependent variable which in this case is gradient measure) by the difference of two respective x-coordinates (or independent variable which in this case is degree measure).

For finding the slope we will use the first and the last point given in the table. So, the slope m will be given by:

$m= \frac{300-(-200)}{270-(-180)} \\ \\ 
m= \frac{500}{450} \\ \\ 
m=1.11$

So rounding of to nearest hundredth, the slope of line representing the conversion of degrees to gradients is 1.11
