Since you are trying to find the direction you have to use
tan theta= y/x
tan theta= 26/-5
theta= tan^-1I26/-5I
theta= 79.11 degrees but since (-5,26) is found in the second quadrant you have to substract 180 - a to obtain the direction angle
theta= 180 -a
=180 - 79.11
theta = 100.88 degrees
vector v has a direction angle of 100.88 degrees
Answer:
Cost of one CD = $9.98
Step-by-step explanation:
Total cost = $214.60
Total shipping and handling fee = $15.00
Number of CDs = 20
Cost of 20 CDs = Total cost - Total shipping and handling fee
= $214.60 - $15.00
= $199.60
Cost of one CD = $199.60 / 20
= $9.98
Cost of one CD = $9.98

Step-by-step explanation:
He used four apples to make an apple pie. you can simply divide 12 by 3. 1/3 of 12 apples would be 4. if you think about it 2/3 would be 8 apples, adding four more apples would be 12 apples making that 3/3.
Answer:
y=75+55x
Step-by-step explanation:
if y represents the total cost, and x represents the total hours, then using the formula y=75+55x gets the total cost for repair services
