The answer would be A
1.20+1.20=2.40+60=3.00
1.20+.60=1.80
G(f(x)) means put replace each x in g(x) by f(x) and simplify it .
Hi there
Paul get after the rise
8+8×0.07=8.56 per hour
Sandy get after the rise
11,100+11,100×0.07=11,877
Good luck!
Answer:
208.8 mi
Step-by-step explanation:
Form a triangle with the centre of the Earth (C) at one point, the horizon (H) as a second point, and the top of Mt. Everest (O) as the third (see diagram).
Let
r = Earth’s radius
h = height of Mt Everest
d = distance to horizon
∆CHO is a right triangle.
d² + r² = (r+h)²
d² + 3959² = (3959+5.5)²
d² + 15 673 681 = 3964.5²
d² + 15 673 681 = 15 717 260 Subtract 15 673 681 from each side
d² = 43 579 Take the square root of each side
d = 208.8 mi
The distance from the top of Mt Everest to the horizon is 208.8 mi.
