A parabola has a vertex at (3,8) and passes through the point (-5,24). If we were to write the equation of the function in the form f(x) = a (x-h)^2 + k, what would the value of "a" be?

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

c

step-by-step explanation:

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
