The senior class at Bay High School buys jerseys to wear to the football games. The cost of the jerseys can be modeled by the equation C=0.1x^2
+2.4x +25, where C is the amount it costs to buy x jerseys. How many
jerseys can they purchase for $500? *

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

the answer is d.x= 90°

y= 50°

arc lm= 100°
