it would be about 51 or 52 percent exact but if you have to round about 50 percent was taken off the shirt.
EXPLANATION: 39 times 0.5 = 19.5
39- 19.5 = 19.50

Answer: 6
8 + 8 = 16
16 - 10 = 6
Answer:
See below in bold.
Step-by-step explanation:
We can write the equation as
y = a(x - 28)(x + 28) as -28 and 28 ( +/- 1/2 * 56) are the zeros of the equation
y has coordinates (0, 32) at the top of the parabola so
32 = a(0 - 28)(0 + 28)
32 = a * (-28*28)
32 = -784 a
a = 32 / -784
a = -0.04082
So the equation is y = -0.04082(x - 28)(x + 28)
y = -0.04082x^2 + 32
The second part is found by first finding the value of x corresponding to y = 22
22 = -0.04082x^2 + 32
-0.04082x^2 = -10
x^2 = 245
x = 15.7 inches.
This is the distance from the centre of the door:
The distance from the edge = 28 - 15.7
= 12,3 inches.
Answer:
m = -2/7
Step-by-step explanation:
We can find the slope when given two points by using
m = (y2-y1)/(x2-x1)
=(4-2)/(-5-2)
=2/-7
= -2/7
