Answer:
based on trigonometry
I will just put up answers to 1-7.26
2-33.34
3-21.33
4-31.87
5-25.59
6-11.01
7-41.81 deg
8-64.23deg
9-12.83deg
10-51.31deg
The answer is A.
Add all the number values together and then divide it by the number of values you have: 43+32+65+88+50+72=350
350/6=58.33
Answer:
4r^2-6rx
Step-by-step explanation:
Answer:
r = 2
r = -1
Step-by-step explanation:
So first, we need to get this is order of: ax^2 + bx + c
3r^2 - 6 - 3r
3^2 - 3r - 6
the formula is: -b ± √b^2 -4ac/2a
"ax^2 + bx + c" = "3^2 - 3r - 6"
a = 3
b = -3
c = -6
-b ± √b^2 -4ac/2a
-(-3) ± √(-3)^2 -4(3)(-6)/2(3)
3 ± √9 + (-12)(-6)/6
3 ± √9 + (72)/6
3 ± √9 + 72/6
3 ± √81/6
3 ± 9/6
3 - 9/6
-6/6
-1 = r
3 + 9/6
12/6
2 = r
