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?

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? 

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?

the winning margin between the top two candidates in an election can be represented by

 $\left|A+B\right|$|A+B| 

 $\left|A-B\right|$|A−B| 

 $\left|A\right|+\left|B\right|$|A|+|B| 

 $\left|A\right|-\left|B\right|$|A|−|B| 

state the domain and range of  $y=\left|-4.9t^2+8.5t-2.23\right|$y=|−4.9t²+8.5t−2.23| 

An equation that describes the maximum and minimum temperatures at which a chemical compound is in a liquid state is given by the absolute value equation (t-50)=50, where T is the temperature in degrees Celsius. Calculate the range in temperature, and identify the chemical compound.

The maximum and minimum length, l, of an 8 ft board with a tolerance of -1/4 and +1/4 in can be determined by solving the equation

(L-0.25)= 96

(L+0.25)= 96

(L-96)= 0.25

(L+96)= 0.25

the brackets symbolize the absolute value sign

A hot air balloon pilot raises a balloon 200 m from the ground, turns off the burner and allows the balloon to decend 60 m before turning the burner on again to raise it another 170 m.

A. use +/- values to determine the total distance the balloon travelled.

B. use absolute values to determine the total vertical distance travelled by the balloon.
