After a rotation of 90° about the origin, the coordinates of the vertices of the image of a triangle are a'(6,3), b'(-2, 1)
and c'(1, 7). what are the coordinates of the vertices of the pre-image?

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without

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).

answe: it will take 4.5 hours for naomi and clair to paint an equal number of square feet
