Answer:
m<S=63°
Step-by-step explanation:
The angle formed with the radius and a tangent is 90 degrees. (<T)
180-90-27=63
Answer:f(x) = 80x + 65f
Step-by-step explanation:
Since x = days and y = total rent, you've been given two points on your function: (5, 465) and (7, 625). We'll find the slope using those two points:
(625 - 465) / (7 - 5) = 160/2 = 80
Then, use m = 80 and one of the points to write the equation of your line in point-slope form:
y - y1 = m(x - x1)
y - 465 = 80(x - 5)
Convert that to standard form:
y = 80(x - 5) + 465
y = 80x - 400 + 465
y = 80x + 65
y - 80x = 65
In function notation, that's:
f(x) = 80x + 65
