the directrix and focus the axis of symmetry (goes through the focus, at right angles to the directrix) the vertex (where the parabola makes its sharpest turn) is halfway between the focus and directrix.
Step-by-step explanation:
If you mean the measure of angle A then the answer is 28°
Answer:
It should be 42.25 instead
Step-by-step explanation:
M∠5=130 <span>and m∠4 =70
</span><span>so
m<2 = 180 - m<5
m<2 = 180 - 130
m<2 = 50
m<3 = 180 - (m<2 + m<4)
</span>m<3 = 180 - (50+70)
m<3 = 180 - 120
m<3 = 60

Answer:
When number of games downloaded is at least 3
Step-by-step explanation:
Let x = number of games downloaded
Members = 50 + 2x
Non members = 20x
50 + 2x = 20x
50 = 20x - 2x
50 = 18x
x = 50/18
x = 2.78
At x = 2.78, both members and non members are paying the same amount
For members to make profits, the value of x must be greater than 2.78
Approximately x = 3
Check:
Members = 50 + 2x
= 50 + 2(3)
= 50 + 6
= 56
Non members = 20x
= 20(3)
= 60
