The number of subscribers y to a newspaper after t years is shown by the equation , where 75 is the initial number of subscribers to a newspaper and t is the time period is years.
The above equation can be rewrite as
which is equivalent to the exponential decay function with rate r=0.05=5%
⇒ The number of subscribers to a newspaper decreased by 5% every year.
The answer is d to the question
Answer:
m = -1/2 and b = 6.5
Step-by-step explanation:
To find the slope of the original line segment, we have to do the change in y/the change in x:
(4-8)/(-5--3) = -4/-2 = 2
2 is the slope of the original line segment, but since this is the perpendicular bisector, we have to take the negative reciprocal of 2 so m = -1/2
To find b we substitute the values of x, y, and m into the equation. Let's use the x value of -3 and the y value of 8:
y = mx + b
8 = -1/2(-3) + b
8 = 3/2 + b
6.5 = b
I believe the answer is positive rotation
Answer:
156 degree
Step-by-step explanation:
supplementary angle add up to 180 degree
180 - 24
= 156
