b. f(x)= x^2 +4
C. F(x) = (x - 4)^2
f(x) = (x - h)^2 is a parabola that opens up and has the line x = h as the vertical axis.
Here, the vertical axis is x = 4, so h must be 4.
The answer is: C. F(x) = (x - 4)^2
answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
answer: 28.56 feet (approx)
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
