Answer:
Step-by-step explanation:
The range of a projectile is given by :
Put R = 20 m, u = 15 m/s and finding the value of angle of projection
So,
So, the required angle of projection is equal to 
.
Since she has a base amount of $500, that will be your y-intercept. 20 is going to be your slope, and since she's withdrawing it, it will be -20. Here's how the equation would be set up (in y = mx + b):
-20x + 500 = 220
*Subtract 500 from both sides*
-20x = -280
*Divide both sides by -20*
x = 14.
Therefore, it will take 14 weeks.
There is a special right triangle in this picture ( with angles 30°- 60°- 90° ). Sides of that triangle are: a, a/2 and a√3/2.
a = 10
h = a/2
h = 10/2 = 5
Answer: A ) 5 inches
His overall net profit would be $500 dollars because every two weeks he makes $500 so over 4 weeks he would make $1000, but lose $500 to rent.
