Substitute -8 for t in the expression, and now you have: h(-8) = -2[(-8) + 5]^2 + 4. Solve inside the parentheses; add -8 and 5.
h(-8) = -2[-3]^2 + 4, solve exponents next by squaring -3.
h(-8) = -2[9] + 4, multiply -2 and 9.
h(-8) = [-18] + 4, add -18 and 4.
h(-8) = -14.

Higher education can be expensive, and most students who seek degrees must accept some burden of debt.
It's not necessary that either one represents a proportional
relationship. But if either one does, then the other one doesn't.
They can't both represent such a relationship.
The graph of a proportional relationship must go through
the origin. If one of a pair of parallel lines goes through
the origin, then the other one doesn't. (If two parallel lines
both went through the origin, then they would both be the
same line.)
Can you restate the question I'm having a hard time understanding what your asking?
You have to know the formula for the volume of a cone.
In high school, there's no other way.
Volume of a cone = (1 / 3) π (radius)² (height)
Volume = (1 / 3) π (12 inches)² (15 inches)
Volume = 720 π = 2,261.95 cubic inches
Rounded to the nearest cubic inch, that's<u> 2,262 cubic inches</u>.
