Answer:

7.0 m/s

Step-by-step explanation:

We can solve this using the 2 kinematic equations and you can use either:

Vf=Vi+at\\\\vf^{2}=vi^{2}+2ad

So let's use the first one.

Vi = initial velocity

Vf = final velocity

a = acceleration due to gravity (constant 9.8m/s²)

t = time

The marble is dropped so this means that it is in free fall. The initial velocity is always 0m/s.

We are given then the following:

d = 2.5m

t = 0.71s

Vi = 0 m/s

a = 9.8m/s²

So we plug in the values we know and solve:

Vf = Vi + at\\\\Vf = 0 m/s + (9.8m/s^{2})(0.71s)\\Vf = 6.958m/s \cong 7.0m/s

Average rate of change for f(x) = x2 − 3x − 10 from x = −5 to x = 10.
11111nata11111 [884]
The average rate of change is the slope of the secant line connecting the points on f(x) from x=-5 to x=10.

In other words, it is just the slope of the straight line connecting the points
(-5,f(-5)) \: and \: (10,f(10))

So we were given ,

f(x) = {x}^{2} - 3x - 10

At
x = - 5
f( - 5) = {( -5 )}^{2} - 3( - 5) - 10
f( - 5) = 25 + 15- 10
f( - 5) = 30

Also at
x = 10
f( 10) = {( 10)}^{2} - 3( 10) - 10.
f( 10) = 100- 30 - 10
f( 10) = 60

The average rate of change
= \frac{f(10) - f( - 5)}{10 - - 5}
= \frac{60- 30}{15}
= \frac{30}{15}
= 2

Find the height of a cone shaped room with a diameter of 144 ft and a volume of 81430.1 cubic ft.
julia-pushkina [17]

Answer:

The height is 15 feet

Step-by-step explanation:

If you use the formula for cone height and substitute in your values:

h=3 x (V/πr^2)

h=3 x (81430.1/72^2π)

h=15
