Answer:

3x^2 + 8  

Step-by-step explanation:

Given functions,

f(x) = 3x + 8 ----(1)

g(x) = x^2 -----(2)

Since,

(fog)(x) =  f( g(x) )      ( Composition of functions )

=f(x^2)             ( From equation (2) )

=3x^2 + 8          ( From equation (1) )

Hence,

(fog)(x)=3x^2 + 8

Step-by-step explanation:

PLZ HELP ASAP. What is the measure of B?
KATRIN_1 [288]

Answer:

C. 55°

Step-by-step explanation:

Note the total measurement of angles for a triangle. The total measurement of all angles in a triangle = 180°

Note that m∠C is a right angle (as shown through the square), and that right angles = 90°

Subtract to find the measurement of the unknown angle (∠B)

∠B = 180 - (∠A + ∠C)

∠B = 180 - (35 + 90)

Simplify. Combine like terms. First, add (solve parenthesis), then subtract.

∠B = 180 - (125)

∠B = 55

m∠B = C. 55°
