P=69 degrees
Q=71 degrees
R=40 degrees
Explanation
All triangles equal up to 180 degrees.
First add all numbers without x.
Then add all xs.
5x+20=180
Subtract 20 from 180
5x=160
Divide 160 by 5
x=40
Answer:
Her answer is wrong because she the object cannot hit the ground at negative seconds. She could’ve have used other methods because she used the quadratic formula. The advantages is that it works for every situation. The disadvantages is that it takes longer. She should’ve used a different method.
Step-by-step explanation:
Graph made up for the given function f(x)=(1/2)^x
Answer:
The volume of a sphere varies with the cube of the radius. Since the Earth is 3.67 times the moon's radius (6371/1736), it has 49.4 times the volume.

Answer:
1) 500 2) $ 1000 debt 3) $350 4) $2500 debt
Step-by-step explanation:
profit = .5x -250
1) O = .5x -250
250 = .5x
500 = x number to break even
2) f(900) = .5 (900) -250 = $200
from the graph g(200) = total debt = $1000
3) f(x) = -75 = .5x-250 results in x = $ 350
4) f(500) = .5(500) - 250 = 0
from the graph, this corresponds to total debt g (f(500) = $2500 debt
