Answer:
The answer would be 15.
Step-by-step explanation:
2x + 7 = x +4
2x = . x +1
x =11
2(11) =7
22-7
15.
The answer should be d because the circumference is 2 time pie r squared
A tangent line is perpendicular to the radius to the point of tangency. Hence QR ⊥ PR. The Pythagorean theorem tells you
(QR)² + (PR)² = (PQ)²
(55 cm)² + (PR)² = (73 cm)²
(PR)² = 2304 cm²
(PR) = √(2304 cm²) = 48 cm
The length of PR is
b. 48 cm
Answer: 40
Step-by-step explanation:
<span>f(x) = -x - 2
</span><span>g(x) = x^2
</span><span>(g°f)(-6) = ?
First, we find f(-6)
</span>f(x) = -x - 2
f(-6) = -(-6) - 2
f(-6) = 6 - 2
f(-6) = 4
Since f(-6) = 4,
(g°f)(-6) = g(4)
g(x) = x^2
g(4) = 4^2
g(4) = 16
Therefore, (g°f)(-6) = 16
