Ruby wants to estimate the height of a streetlamp post on her block. She stands a certain

distance from streetlamp post and measures the angle of elevation to the top of the post (from

the ground) to be 71°. She walks 12 feet away from the lamp post. She then measures the angle

of elevation to the top of the post again, and this time finds it to be 46°. Estimate the height of

the street lamp post.

The axis of symmetry for the graph of the function f(x)=1/4^2+bx +10 is x=6. what is the value of b?

1. evaluate 8x(2)y9(-2) for x=-1 and y=2 2. simplify the equation. -() 3. simplify the expression. [tex]\frac{5}{x(-2) y9(5)}[/tex]

Tom is the deli manager at a grocery store. he needs to schedule employee to staff the deli department for no more that 260 person-hours per week. tom has one part-time employee who works 20 person-hours per week. each full-time employee works 40 person-hours per week. write and inequality to determine n, the number of full-time employees tom may schedule, so that his employees work on more than 260 person-hours per week. graph the solution set to this inequality.
