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?

Hannah and Jenna are travelling to a volleyball tournament in Grande Prairie, and leave at the same time. Hannah's parents drive her from Edmonton to grande Prairie, a distance of 460 km. Jenna's team takes a bus from Dawson Creek, BC to Grande Prairie, a distance of 130 km. Hannah's parents vehicle travels 10km/h faster than Jenna's, and Jenna arrives at the tournament 3 hours eairlier than Hannah. Determine how fast Hannah's parents are driving? 

Larry likes skeet shooting, where a clay disc is shot into the air and the participant tries to shoot it as it flies through the air. The discs are released from a firing mechanism that sits at ground level and shoots the disc on average a horizontal distance of 120m on a parabolic path. The average maximum height a disc reaches is 40m.

sketch a diagram that represents it with a equation that represents the flight of the clay disc. 

Determine the domain and range of the quadratic equation.

An angle is in standard postion, such that sin  $\theta$θ = $\frac{-5}{7}$−57  . What are the possible values of  $\theta$θ , to the nearest degree, if 0 degrees $\le\theta<360$≤θ<360 degrees?

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.

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.
