Answer: 12,888 in^2 (inches squared)
Step-by-step explanation:
Answer:
15 m/s
Step-by-step explanation:
Velocity is the derivative of position:
v(t) = s'(t) = 24 +6t -3t^2
v(3) = 24 +3(6 -3·3) = 15
At t=3 seconds, the velocity of the body is 15 m/s.

Answer:
The composite function;
f(g(x) = 2x^2 + 15
Step-by-step explanation:
Given f(x) = 2x + 1 and g(x) = x^2 + 7 ;
we want to find f(g(x))
This is simply a composite function which involves fixing the function g(x) into f(x)
Thus, we have
f(g(x)) = 2(x^2 + 7) + 1
f(g(x)) = 2x^2 + 14 + 1
f(g(x)) = 2x^2 + 15
Answer:
942 6/7 cm²
Step-by-step explanation:
Since O = Center of bigger circle, OA = Radius of bigger circle.
∴ Area of smaller circle - Area of bigger circle = Area of shaded part.
∴ Area of smaller circle = 22/7 × 10²
= 22/7 × 100
= 2200/7
= 314 2/7 cm²
∴ Area of bigger circle = 22/7 × 20 ²
= 22/7 × 400
= 1257 1/7 cm²
∴ Area of shaded part = 1257 1/7 - 314 2/7
= 942 6/7 cm²
