Answer:

12 feet per second.

Step-by-step explanation:

Please consider the complete question.

Ian tosses a bone up in the air for his dog, Spot. The height, h, in feet, that Spot is above the ground at the time t seconds after she jumps for the bone can be represented $h(t)=-16t^2+20t$ .

What is Spot's average rate of ascent, in feet per second, from the time she jumps into the air to the time she catches the bone at t=1/2?

We will use average rate of change formula to solve our given problem.

$\text{Average rate of change}=\frac{f(b)-f(a)}{b-a}$

$\text{Average rate of change}=\frac{h(\frac{1}{2})-h(0)}{\frac{1}{2}-0}$

$\text{Average rate of change}=\frac{-16\cdot(\frac{1}{2})^2+20\cdot \frac{1}{2}-(-16\cdot(0)^2+20\cdot (0))}{\frac{1}{2}-0}$

$\text{Average rate of change}=\frac{-16\cdot\frac{1}{4}+10-(0)}{\frac{1}{2}}$

$\text{Average rate of change}=\frac{-4+10}{\frac{1}{2}}$

$\text{Average rate of change}=\frac{6}{\frac{1}{2}}$

$\text{Average rate of change}=\frac{2\cdot 6}{1}$

$\text{Average rate of change}=12$

Therefore, Spot's average rate of ascent is 12 feet per second.

What function transforms the graph of the parent function f(x)=2^x by reflecting it across the y axis and translating it up 5 un

babunello [35]

Coefficient of x is less than 0 then it's across the y axis

So f(x)=2^x ---> g(x) = 2^-x

Then translating it up 5 units, should be g(x) = 2^(-x) + 5

Answer is the last one

g(x) = 2^(-x) + 5

Which expression represents the area of the figure?

lys-0071 [83]

Answer:

The solution is 8x2 + 16x + 8. The region can be divided into a triangle and a rectangle.

Area of Triangle=

(2x + 2)(2x)

Area of Triangle = 2x2 + 2x

Area of Rectangle: (2x + 2)(3x + 4)

Area of Rectangle: 6x2 + 14x + 8

Sum of Two Regions: 8x2 + 16x + 8
