Answer:
The original point (x , y) —> the point rotated (-y , x)
Step-by-step explanation:
Circle equation
(x - h)^2 + (y - k)^2 = r^2
Since radius isn't given use the center and point, with the distance formula, to find the radius.
D=sqrt((x2-x2)^2+)y2-y1)^2)
D=sqrt((1-0)^2+(2-6)^2
D=sqrt(1+16)
D=sqrt 17
radius = sqrt 17
(h, k) is the center and r is the radius
(x - 1)^2 + (y - 2)^2 = 17
5/4 is the constant of proportionality
Answer:
he cable car's elevation will be 750 feet after 15 minutes
Step-by-step explanation:
Given:
elevation, e =2,000 feet
rate, I = 50 feet/minute
The equation that models the car's elevation, e, after t minutes is e = |t
The cable car's elevation will be 750 feet after how many minutes?
since, e = It
for 2,000 feet = 50 feet/minute * t
t = 2000/50 =40minutes
using the same constant rate, I for 750ft, T =
since, e = It
for 750 feet = 50 feet/minute * t
t = 750/50 =15minutes
First you gotta distribute.
4 (1.75y - 3.5) + 1.25y
4 * 1.75 y = 7
4* (-3.5) = (-14)
7y - 14 + 1.25y
Combine like terms
8.25y - 14
