Answer:
4) J
5) D
Step-by-step explanation:
4) 416 = 2x² - 6x
2x² - 6x - 416 = 0
x² - 3x - 208 = 0
x² - 16x + 13x - 208 = 0
x(x - 16) + 13(x - 16) = 0
(x - 16)(x + 13) = 0
x = 16, -13(not possible)
So 16 rows
5) y = a(x - h)² + k
y = a(x - 3)² - 7
When x = 1, y = -10
-10 = a (1 - 3)² - 7
-10 = 4a - 7
4a = -3
a = -¾
y = -¾(x - 3)² - 7
First evaluate

what angles in domain of [-pi/2, pi/2] make sin = 0

Now we can evaluate the cos function:
Use the Midpoint Theorem to solve for x.
The theorem states that the line between the midpoints of a triangle is half the length of the side it's opposite to.
Line BF is opposite to Line CE. Line CE has a length of 88. Therefore, we can set up the following equation:


Divide both sides by 2 to get x by itself:

The value of x is
22.
Answer:
x = 3
y = 6
Step-by-step explanation:
Apply the angle bisector theorem to find both variables.
Based on the theorem, we would have the following:
✔️x/2 = 6/4
Cross multiply
x*4 = 6*2
4x = 12
4x/4 = 12/4
x = 3
✔️9/y = 3/(8 - y)
Cross multiply
9(8 - y) = 3*y
72 - 9y = 3y
72 = 3y + 9y
72 = 12y
72/12 = 12y/12
6 = y
y = 6
