$The~average~rate~of~change~of~the~given~quadratic~function~on~the$ $interval~0$ ≤ x ≤ $4$ $is~the~slope~of~the~secant~line~connecting~the~points~(0,f(0))~and~(4,f(4)).$

$The~average~rate~of~change~is:$

$=\frac{f(4)-f(0)}{4-0}$

$Now,from~the~graph,f(0)~is~0~and~f(4)~is~-4.$

$We~plug~in~these~values~to~obtain;$

$=\frac{-4-0}{4-0}$

$And~then,this~simplifies~to:$

$=\frac{-4}{4}$

$which~is~obviously:$

$=-1$

$Thus,~the~average~rate~of~change~for~the~given~quadratic~function$ $whose~graph~is~shown~on~0$ ≤ x ≤ $4~is~=-1.$

Light travels at 186,000 miles per second. Light takes about 11⁄3 seconds to travel from the earth to the moon. Calculate the di

san4es73 [151]

Answer:

682,000 miles

Step-by-step explanation:

Using the ratio of 186,000 miles per second:

$\frac{miles}{second}=\frac{186,000}{1}$

we can set up a proportion (equivalent ratios) to find the distance, in miles, from the earth to the moon

$\frac{186,000}{1}=\frac{x}{\frac{11}{3}}$ where 'x' is the number of miles between the earth and the moon

Cross-multiply: x = 186,000* $\frac{11}{3}$

Solve for x = 682,000 miles

Which expression is equivalent to (2^3)^-5

Ostrovityanka [42]

Hi!

You didn't list the options, but I think I know the answer. Let me know if my answer isn't listed! :)

$(x^{3} )^{-5}$
We need to multiply the exponents.
3 · -5 = -15

The answer is $2^{-15}$

Hope this helps! :)
