The formula

son4ous [18]

Answer:

The truck travel must to have a constant speed of $22.06\ ft/sec$

Step-by-step explanation:

we have

$d=1.3t^{2}+t+2$

where

d expresses a car's distance in feet

t is the number of seconds

Find the distance d for t=8 sec

$d=1.3(8)^{2}+8+2=93.2\ ft$

Find the distance d for t=8.2 sec

$d=1.3(8.2)^{2}+8.2+2=97.612\ ft$

The total distance in this interval of 0.2 sec is

$97.612-93.2=4.412\ ft$

Find the speed of the car

Divide the total distance by the time

$4.412/0.2=22.06\ ft/sec$

therefore

The truck travel must to have a constant speed of $22.06\ ft/sec$

I need to know The value of f(1/2)

Lostsunrise [7]

$\huge\boxed{\textsf{a.)}\ 10}$

Substitute $\frac{1}{2}$ for $x$ .

$f\left(\frac{1}{2}\right)=5\cdot4^\frac{1}{2}$

Use $a^\frac{m}{n}=\sqrt[n]{a^m}$ .

$\begin{aligned}f\left(\frac{1}{2}\right)&=5\cdot\sqrt[2]{4^1}\\&=5\cdot\sqrt[2]{4}\\&=5\cdot2\\&=\boxed{10}\end{aligned}$

Answer:

d=18 feet

Step-by-step explanation:

The volume of a sphere is represented by the equation $V=\frac{4}{3}\pi r$ ³, where r is the radius. If the volume is 972 $\pi$ ,

$972\pi =\frac{4}{3}\pi r$ ³

Divide $\pi$ from each side,

$972=\frac{4}{3} r$ ³

Multiply each side by 3/4 to get rid of the fraction,

$r$ ³ $=729$

Using the cube root, we find that 729 is actually a perfect cube.

$r=9$

Now, the diameter is 2 times the radius, so

9×2=18

So, the measure of the diameter is 18 feet.
