X=12, divide 7.5/5 times x/8. cross multiply yo get 7.5 x 8 and 5x, 60=5x, x=12
Answer:
x∈[2nπ−5π/6, 2nπ−π/6]∪{(4n+1)π/2}, n ϵ I
Step-by-step explanation:
1−2sin2 x≤−sin x ⇒ (2sin x+1)(sin x−1)≥0
sin x≤−1/2 or sin x≥1
−5π/6+2nπ≤x≤−π/6+2nπ or , n ϵ I x=(4n+1)π/2, n ϵ I⇒ -5π6+2nπ≤x≤-π6+2nπ or , n ϵ I x=4n+1π2, n ϵ I (as sin x = 1 is valid only)
In general⇒ In general x∈[2nπ−5π/6, 2nπ−π/6]∪{(4n+1)π/2}, n ϵ I
Answer:
Coordinates are ( 1,3 ) x=1 y=3
F(x) = 1/4x -3 = 1/4*12-3
= 1/45
To find the answer, you must subtract 1632 and 74, which results in 1558, so the Transamerica Pyramid is 1558 ft tall.
I hope this helps.
