Answer:
An inscribed angle that opens to a diameter has an intersected arc that is 180 degrees. The inscribed angle is a right angle (90 degrees) because

Step-by-step explanation:
we know that
The inscribed angle is half that of the arc comprising
Remember that
The diameter divide the circle into two equal parts
so
An inscribed angle that opens to a diameter has an intersected arc that is 180 degrees
The inscribed angle is 90 degrees because

therefore
An inscribed angle that opens to a diameter has an intersected arc that is 180 degrees. The inscribed angle is a right angle (90 degrees) because

Answer:
y = - 1/4 + 4
Step-by-step explanation:
y = 4x - 7
Slope = 4
Slope of the perpendicular line = -1/4
Point (8,2)
(b) y-intercept: 2 - (-1/4)(8)
= 2 + 2 = 4
Answer:
D
Step-by-step explanation:
The y-intercept must be at -7, so that eliminates C.
Because of the direction of the line, the slope needs to be negative. This eliminates B.
The slope of the line is -7/6, so D is the correct answer.
Answer:
500(10) + 600(2)
Step-by-step explanation:
F(x) = (2x-1)(x+2)/ (x+2)
f(x) = 2x-1
f(-2) = 2(-2)-1
f(-2) = -5
