Answer:
3/8 π radians
Step-by-step explanation:
The Area of a sector when then central angle is in radians = 1/2r² θ
Where
θ = central angle = ?
r = 16 cm
Area of the sector = 48πcm²
Hence
Central angle = Area of a sector ÷ (1/2r²)
= 48πcm² ÷ (1/2 × 16²)
= 48πcm² ÷ 128
Central angle = 3/8π radians
Therefore, Central angle = 3/8π radians
Answer:
n=-20
Step-by-step explanation:
First subtract four from both sides then you'll get
-4=n/5
Second multiply 5 to both sides then you'll get
n=-20
Answer:
43
Step-by-step explanation: Ive took the test :)
F(x) = x-3 and g(x) = x+11
f(x) *g(x) = (x-3)(x+11) = x^2 +11x -3x -33 = x^2 +8x -33
so choice D. is right
hope helped
