45. Reason in a video game, you must score 5,500 points to complete level 1. To move
through each additional level, you must
score an additional 3,250 points. What
number would you use as a when writing
an arithmetic sequence to represent this
situation? What would n represent? Write an
explicit formula to represent this situation.
Write a recursive formula to represent this
situation.

Step-by-step explanation:

a1 = 5500, since you are starting there, and n would represent the level you want to complete. 3250 would be d, or the number you are going up by each time.

This would give you the equation an = 5500 + 3250(n-1) as the explicit formula, and an = an-1 + 3250 as your recursive formula.

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,

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51
