Tes, because acceleration is how fast it is speeding up, the average speed isn't being given because tornados don't last more than a few miles, and instantaneous speed gives current velocity in a certain direction at a certain time, therefore it would be anytime, including 3 minutes ago, meaning velocity, the current speed, is correct.

Which expression below gives the average rate of change of the function h(x) = 4^x+2 + 7 on the interval –3 ≤ x ≤ 5?
expeople1 [14]

Answer:

4^(5+2) + 7 - (4^(-3+2) +7)

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

5 +3

Step-by-step explanation:

The average rate of change is given by

h(5) - h(-3)

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

5 - -3

h(5) - h(-3)

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

5 +3

h(5) = 4^(5+2) + 7

h(-3) = 4^(-3+2) +7

4^(5+2) + 7 - (4^(-3+2) +7)

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

5 +3

I have a square with a side of 5.25 in. There is a circle inside this square that is big enough to touch all four sides. What is
DENIUS [597]

Answer:

5.9125in^2

Step-by-step explanation:

Step one:

Given data

Dimension of square= 5.25 in

Area of sqaure= 5.25^2= 27.5625  in^2

We are told that the sides of the circle touch the sides of the square

hence the diameter of the circle is 5.25in

radius= 5.25/2= 2.625 in

Area of  circle= πr^2

Area of circle = 3.142*2.625^2

Area of circle=3.142*6.890625

Area of circle= 21.65 in^2

Step two:

The area that is not inside the circle

=Area of square-Area of circle

=27.5625- 21.65

=5.9125in^2
