Answer:7.967
Step-by-step explanation:
Answer:
(29-26) * 3 = 9
Step-by-step explanation:
<span>Surface area</span> = 2πr(h+r) = 2 * 3.14 * 3(8+3) = 207.24 yd²
Answer:
4.
Step-by-step explanation:
(sec α - tan α)(sec α + tan α) = sec^2 α - tan^2α
But sec^2 α = 1 + tan^2 α so
sec^2 α - tan^2α = 1 + tan^2 α - tan^2α
= 1
so 1 = (sec α - tan α)(sec α + tan α) = 1/4 * x where x is sec α + tan α
1/4 * x = 1
x = 4.
Answer:
x=3
Step-by-step explanation:
The equation is x² + 5x = 24, so 3² +15 would be the perfect match. This is because 9+15=24.
