Hello,
Yes since (2*6.4)²+9.6²=256=16²
Angle A=90°
To find this, just plug the numbers into the expressions.
5x = y
5(2) = 7
10 = 7
So it can't be A.
x + 2 = y
2 + 2 = 7
4 = 7
x + 4 = y
2 + 4 = 7
6 = 7
2x + 3 = y
2(2) + 3 = 7
7 = 7
The correct answer is
D. 2x + 3
Measure = 1/2 (120-30)
1/2(90)
45
Answer = 45°
When the transverse axis is horizontal, a hyperbola centered at (h,k) has formula (x-h)^2/a^2-(y-k)^2/b^2=1. Plug in h=2, k=1, the formula is (x-2)^2/a^2-(y-1)^2/b^2=1 for some a,b. If the transverse axis is vertical, the formula is (y-h)^2/a^2-(x-k)^2/b^2=1, and (y-2)^2/a^2-(x-1)^2/b^2=1 in our case.
Answer:
52.9°
Step-by-step explanation:
step 1
we know that
The total number of successful United States space launches that happened in the years 1957-1995 is equal to

step 2
The numbers of successful United States space launches that happened in the years 1980-1989 is equal to

step 3
The percentage of successful United States space launches that happened in the years 1980-1989 is equal to

step 4
Find out the measure of the central angle you would draw in a circle graph to represent the number of successful United States space launches that happened in the years 1980-1989
we know that
In a circle, 360 degrees represent the 100%
so
using proportion
Find out the measure of the central angle by a percentage of 14.68%
