8 0

Answer:

Sea level is 0 meters. A cliff by the ocean is 12 meters above sea level. Around that area, the seafloor is 8 meters below sea level. How many meters  is the top of the cliff to the seafloor?

How to solve:

8 below zero is -8

The expression 12 - (-8) is the same as the expression 12 + 8

12 + 8 = 20

20 meters

Use the given function and the given interval to complete parts a and b. f (x )f(x)equals=negative 2 x cubed plus 21 x squared m
Leya [2.2K]

Answer:

(A)The absolute maximum of f(x) is at x=5

Step-by-step explanation:

F(x)=−2x³+21x²−60x on [1,6]

Find the first derivative.

f'(x)=-6x²+42x-60

Set the first derivative equal to zero.

-6x²+42x-60=0

Solve to find the critical points.

x=2,5

Next, we use the endpoints and all critical points on the interval to test for any absolute extrema over the given interval.

x=1,2,5,6

This is done by evaluating the function at x=1,2,5,6.

F(1)=−2(1)³+21(1)²−60(1)=-41

F(2)=−2(2)³+21(2)²−60(2)=-52

F(5)=−2(5)³+21(5)²−60(5)=-25

F(6)=−2(6)³+21(6)²−60(6)=-36

The maximum will occur at the highest f(x) value and the minimum will occur at the lowest f(x) value.

Absolute Maximum: (5,-25)

Absolute Minimum: (2,-52)

The graph is attached.

The absolute minimum and maximum of f(x) are (2,-52) and (5,-25) respectively.

Miranda is selling ice cream at the park to help raise money for the animal shelter. The amount of money she raises for the shel
luda_lava [24]

Answer:

The question is lacking the detail of the price of the ice cream cones.

Assuming the ice cream cones cost $2 each then she would have to sell;

= 250/2

= 125 ice cream cones

<em>If she sells 125 ice cream cones, she will be able to raise $250 if the cones are sold at $2 each. </em>

A cone-shaped pile of sawdust has a base diameter of 20 feet, and is 7 feet tall. Find the volume of the pile.
Phoenix [80]

Answer:

About 733.04 feet


Step-by-step explanation:

Volume of Cone is given by the formula  V=\frac{1}{3}\pi r^2h

Where

  • V is the volume
  • r is the radius
  • h is the height

Given height as 7 ft, and radius is 10 feet (Radius is half of diameter(20))

<em>Substituting into formula, we get:</em>

V=\frac{1}{3}\pi r^2 h\\V=\frac{1}{3}\pi (10)^2(7)\\V=\frac{700\pi}{3}\\V=733.04 ft
