H(x) = -(x + 11)^2 + 1 1) What are the zeros of the function?
Write the smaller x first, and the larger x second.
smaller x =
larger x =
2) What is the vertex of the parabola?
( [ ] , [ ] )

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

i need more details

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!

yeah i know the problem you need. i am taking it right now. the answer is step 3
