Ahmed worked all summer for a bee farmer. Ahmed was paid $400.00 the first week. The farmer paid a $50.00 raise per week for each additional week of employment. Ahmed worked on the bee farm for 8 weeks before his first year of university began.

Ive figured a and b but im confused with question c and d. 

a. Write out the first three weeks of earnings. Is this an arithmetic or geometric sequence? Justify

b. Calculate how much Ahmed earned over the 8 weeks of summer.

c. The money Ahmed earned over the summer was used for miscellaneous expenses at university. At the start of the ninth week of school he had $3 000.00 in his bank account. How much money did Ahmed spend each week?

d. The school year is approximately 32 weeks long. Will Ahmed have enough money if he continues to spend his savings at the same rate?

For the construction of a deck surrounding a bay window, Tricia must cut several boards at an angle of 120 degrees. Setting up her mitre saw, she sets an angle of 30 degrees. Will this cut the wood at the correct angle? if not, what angle should she use if her mitre saw can only be moved up to 90 degrees.

how do you solve the following equation by completing the sqaure?

y= -x^2/90+4x/3

The use of a ladder is considered safe if the angle between the ground and the ladder is less than 75 degrees. Charlie's 5 ft long ladder is 1 ft from the base of a wall. 

a) Is the ladder being used safely?

b) How far away from the wall is the minimum distance charlie's other ladder should be if it is 10 ft long?

Determine the value of  $\theta$θ, an angle in standard postion, where  $\sin\theta=-\frac{1}{2}$sinθ=−12  and tan $\theta=\frac{\sqrt{3}}{3}$θ=√33  ,  $0degrees\le\theta<360degrees$0degrees≤θ<360degrees.   

The point (-9, 40) is on the terminal arm of an angle,  $\theta$θ in standard position. 

a. what is the length of the line segment connecting the orgin to the point (-9,40)

b. Determine the measure of  $\theta$θ , to the nearest tenth of a degree. 

Raphael tours the leaning tower of Pisa. From the base of the short side of the tower, Raphael walks 137m and measures the distance to the top of the short side of the tower to be 142 m, with angle of elevation of 23 degrees. Determine the height of the short side of the leaning tower of pisa.
