In set of prime numbers P 2ℙ2, find the change-of-coordinates matrix from the basis Upper B equals StartSet 1 minus 2 t plus t squared comma 3 minus 5 t plus 4 t squared comma 2 minus 2 t plus 5 t squared EndSetB=1−2t+t2,3−5t+4t2,2−2t+5t2 to the standard basis Upper C equals StartSet 1 comma t comma t squared EndSetC=1,t, t2. Then find the B-coordinate vector for negative 6 plus 10 t minus 7 t squared−6+10t−7t2.

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).

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer
