The volume of a sphere is
V_s = 4/3 * pi * r_s^3
The volume of a cone is
V_c = 1/3 * pi * h * r_c^2
Since we know that the two volumes are equal, we can say
V_s = V_c
4/3 * pi * r_s^3 = 1/3 * pi * h * r_c^2
Let us now isolate r_c, the radius of the cone:
4/3*r_s^3 = 1/3 *h*r_c^2
sqrt((4*r_s^3)/h) =r_c = 12 cm
So the radius of the cone is 12 cm
Y = sit ups, x= days
y= 2x + 15
33 = 2x + 15 (subtract 15 from both sides)
18 = 2x (divide both sides by 2)
9 = x, 9 days
You have to find the mean.
Add up all the points from the assignments and the 80.
Then Divide. For example, if there are 23 assignments in the grade book, divide by 23.
Now you have your final grade.
Example: 80+ 76 + 59 + 79 = 294
There are four assignments so you divide by four: 294÷4= 73.5
Final grade is 73.5
I hoped this helped.
Answer:
Im not sure exactly what you want the function to be. Because it can be any number. only the signs would change it
Step-by-step explanation:
okay so lets try this then..
if f(x) is an even number...let say 2
then f(-2)= 2x²+x+6
then it would be 2(-2²)+(-2)+6......-4

To understand math, it is helpful to understand the vocabulary of math. It is difficult to obtain any meaning from a communication when one doesn't know the language.
