Evaluate the following expression: (-3)^-2

Step-by-step explanation:

Anything to the negative power becomes a fraction

So here we have (-3)⁻² which then becomes

This then simplifies to

i think the amount would be $140.62

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
