A 12-foot ladder is leaned against a wall so that it is 5 feet from the base of the wall. You’re hoping the ladder rests at least 11 feet high on the wall in order to avoid some paintings and such that are hung up currently. Does the ladder reach high enough? Justify mathematically.

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

126 maybe. sorry

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).

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
