The farthest distance a satellite signal can directly reach is the length of the segment tangent to the curve of earth’s surface. if a satellite signal could reach an unlimited distance, could half of the earth’s surface be reached by the signal at one time? explain.

answer: idk wbu

step-by-step explanation: umm..

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
