Since you don't have the picture, I can explain how to do the problem. Then, you can select the correct answer.
To find the area of a parallelogram, you must multiply the base times the height. If you have those 2 values, just multiply them and you will be done.
Answer:
A. { -20, -10, 20 }
Step-by-step explanation:
Given:
The function is given as:

Let us simplify the function.
First, we use the identity 

Next, we use the identity 

Now, the function can be rewritten as:

Now, the zeros are those values of
for which 
Now, for
, we must have either of the factors 0.


The factors
and
can have no zeros as the first one has imaginary roots and second one is always greater than 0 irrespective of the
values.
So, the possible set of zeros are { -20, 10, 20 }.

Answer:
<u>The volume of a mound of salt-sand mixture is 589.05 feet ³ or 589.05 cubic feet.</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
Diameter of a mound of the mixture = 15 feet
Height (h) of the mound of the mixture = 10 feet
How much salt-sand mixture is there?
2. Let's find the volume of a mound of mixture with a conical shape:
For doing that, we need to use the volume formula of a cone.
It's: 1/3 * π * r² * h
Replacing with real values, we have:
1/3 * 3.1416 * 7.5 ² * 10 (Diameter = 15, so radius = Diameter/2 = 15/2 = 7.5)
Volume = 1/3 * 3.1416 * 56.25 * 10
Volume = 1/3 * 3.1416 * 562.5 (56.25 * 10 = 562.5)
<u>Volume = 187.5 * 3.1416 = 589.05 feet ³ or 589.05 cubic feet.</u>
Answer:
yes
