I am sure that the function will be ODD
I HOPE I HELP✍️
Hey there! :)
Answer:
C(-1) = -5.
Step-by-step explanation:
C(x) = -4x² + 4x + 3
Plug in -1 for x to solve for C(-1):
C(-1) = -4(-1)² + 4(-1) + 3
Simplify:
C(-1) = -4 + (-4) + 3
C(-1) = -5
Let's make this simple. Let's have the small cone have a radius 1 and the height 1. This would make the bigger
cone
have a radius of 1 and the height of 2.
With this information, lets get the volume of both cones. The formula is this:

Plug in numbers:
Small cone:

Big cone:

The small cone has a volume of

The big cone has a volume of

Now, you want to find how many small cones you need to have the same total volume of the big cone.

You have the difference of pi over 3 comparing the big cone to the small one. You realize that the small cone has the same volume of that. Therefore,
you need 2 small cones to have the same total volume as the larger cone
It is x > 5. You have to add 5 to both sides then divide by 5 in each side.
Answer:
$15
Step-by-step explanation:
The original price of the mirror is unknown, so let's call it x.
The discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.
