Answer: 28.26
Step-by-step explanation:
Formula : 






or


<span>ΔPQR is a right triangle
∡Q is a right angle. ⇒⇒⇒ ∡Q = 90°
QR measures 33 point 8 ⇒⇒⇒ QR = 33.8 ⇒ leg of the triangle
PR measures 57 point 6 ⇒⇒⇒ PR = 57.6 ⇒ hypotenuse of the triangle
we can find ∡P using sin function
sin P = QR/PR = 33.8/57.6 = 0.5868
∴ ∡P =

≈ 35.93°</span>
Answer:
A,B,C
Step-by-step explanation:
Let's first calculate the inner functions, then fill in in the outer one:
g(-1) = 1/-1 = -1.
f(-1) = (-1)^2 + 9(-1) = 1 - 9 = -8
And then
f(1/2) = (1/2)^2 + 9(1/2) = 1/4 + 9/2 = 19/4
g(19/4) = 4/19
