Answer:</h3>
C. x=24, y = 8√3
<h3>
Step-by-step explanation:</h3>
The side ratios in a 30°-60°-90° right triangle are ...
... 1 : √3 : 2 = y : x : 16√3
The shortest side, y, is half the length of the longest, 16√3, so is 8√3.
The mid-length side, x, is √3 times the shortest side, so is 8(√3)(√3) = 24.
The solutions are x = 24, y = 8√3.
Answer: A
Step-by-step explanation:
Solve the equation by replacing x with -7 and then -1.
Then subtract the two to find the difference and divide that by the difference between -7 and -1.
f(-7) = -7^2 + 2(-7) -8 = 49 -14 -8 = 27
f(-1) = -1^2 + 2(-1) -8 = 1 -2 - 8 = -9
Difference between 27 and -9 = -36
Difference between -1 and -7 = -6
Rate of change = -36 /-6 = 6
Answer:(0,4)
Step-by-step explanation:
4x+5y=20
4(0)+5y=20
5y=20
5x/5=20/5
y=4
4x+5(4)=20
4x+20=20
-20 -20
4x=0
4x/4=0/4
x=0
4x+5y=20
4(0)+5(4)=20
0+20=20
20=20
I think this is right
