Answer:

Average\ Speed = \frac{s(7) - s(2)}{5}

Step-by-step explanation:

Given

t = 2 to 7

Required

Find the average speed over these intervals

The function is not given; so, I'll represent the function as s(t)

When t = 2;

s(t)= s(2)

When t = 7

s(t) = s(7)

Average\ Speed = \frac{Change\ in\ Distance}{Change\ in\ Time}

This gives:

Average\ Speed = \frac{s(7) - s(2)}{7 - 2}

Average\ Speed = \frac{s(7) - s(2)}{5}

Volume of the prism = 75 cubic feet

Solution:

The image given is a rectangular prism (or) a cuboid.

Area of base = l × b = 25 square feet

Height of the prism = 3 feet

Volume of the prism = l × b × h

                                  = (l × b) × h

                                  = 25 × 3

                                  = 75 cubic feet

Volume of the prism = 75 cubic feet

Hence, the volume of the prism is 75 cubic feet.

(4x10^2) - (2x10^-1)
balandron [24]

Answer:

Step-by-step explanation:

The LCD here is 10.

Multiplying numerator and denominator of (4*10^2) by 10 results in:

40*10^3

-------------

     10

and rewriting (2x10^-1) with positive exponent in the denominator results in:

   2

---------

    10

So, before simplification, this difference comes out to be:

40000 - 2        39998            19999

----------------- = ---------------- or ------------

        10                   10                   5
