Consider a rectangle with the vertices at the following coordinates:(3,-9) (3,-1) (7,-1) (7,-9). Which of the following transformations will map the rectangle onto itself.

Select all that apply :

A 90 degree rotation about the point (5,-5)

A 180 degree rotation about the point (5,-5)

A 270 degree rotation about the point (5,-5)

A reflection over the line x=5

A reflection over the line y=-5

A reflection over the line y=x

something over 10 so ? /10

step-by-step explanation:

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

answer: i think you should do the math and pay attention in class : )

step-by-step explanation:

that is truly what   think but if i get the answer i will

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).
