Answer:
f ≥ 5
Step-by-step explanation:
Translating the word problem into an algebraic expression, we have;
2(f - 4) ≥ 2
Opening the bracket, we have;
2f - 8 ≥ 2
Rearranging the equation, we have;
2f ≥ 2 + 8
2f ≥ 10
Dividing both sides by 2, we have;
f ≥ 5
Therefore, the possible values for Felipe’s age is 5, 6, 7, 8, 10 till infinity.
4a-2b
Factor out 2 (common term):
2(2a-b)
The formula of interest is
A = (1/2)r²·θ
You have A = 70 m², θ = 170° = 17π/18 rad. Then the radius is found from
70 m² = (1/2)r²(17π/18)
(36·70 m²)/(17π) = r²
r ≈ √47.18476 m
r ≈ 6.9 m
