Answer:
Graph the trigonometric function using the amplitude, period, phase shift, and vertical shift.
Amplitude: 1
Period: π
Phase Shift: 0 (
0 to the right)
Vertical Shift: 1
Answer: x=9
Step-by-step explanation:
The bottom triangle that has a 40° is an isosceles triangle, therefore the other angle at the bottom right is also 40°. This leaves the top angle to be 100°.
180=40+40+x
180=80+x
x=100
Now, to find ∠2, you can tell it is a supplementary angle. Therefore, the 2 angles add up to 180°
180-100=∠2
80°=∠2
The problem states that ∠2 is 9x-1. We know that ∠2 is 80°. We can solve for x.
80=9x-1
81=9x
x=9
First you need the equation y=mx+b
you plug in x and y do find b the y intercept
-5 = -1/2*4 +b
-5 = -2 + b
b = -3
y = -1/2x-3
I think your diagram had an error because the instruction says that it is a SQUARE frame with sides that are 8 inches long.
Anyways, following the question, the area of the shaded parts should be:
2(8 x 2) + 2(8 - 2 - 2)(2)
= 32 + 16
= 48 sq in.
Answer:
d) x+y = 4
Step-by-step explanation:
(−1, 5) and (1, 3)
y = mx + b
m = (3 - 5) / (1 - (-1)) = -2 / 2 = -1
b = y - mx = 3 - ((-1) x 1) = 4
equation: y = -x + 4
