I need help with my geometry homework.

1.  substitute in for parabola, substituting for the same equation does nothing

2. the factors for y^2+y-20 are (y+5)(y-4)

3. solutions are y=4 or -5

4. substituting y=-5 in the equation

-5 = x^2 -5

0=x^2

x=0

therefore the three points of intersection are (0,-5), (-3,4), (3,4)

answer: rolling a number cube and flipping a coin.

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
