Answer:
y=2x^2-8x+6
Step-by-step explanation:
Use pythagorena theorme
D=

NOTE: x1 and x2 means the first x and second x, not x^1 and x^2
points given are
(1,1)
(5,6)
x1=1
y1=1
x2=5
y2=6

answer is B
This equation is an example of a Limacon with inner loop. By using the symmetry tests where:
POLAR AXIS/HORIZONTAL:
replace a) θ by -θ, b) r by -r and θ by π-<span>θ
VERTICAL AXIS:
replace a) </span>θ by π-θ, b) r by -r and θ by -<span>θ
POLE:
replace a) </span>θ by π+<span>θ, b) r by -r
If any of these rules, after replacing it in the equation, results to the original equation (making it the equivalent) then it is symmetrical to that axis.
In this case, it is only symmetrical about the polar/horizontal axis. </span>
The answer would be 2.4, or in fraction form 12/5. Please mark brainliest <3
Answer:
Step-by-step explanation:
Let d be the diameter of the wheel.
Circumference = πd
(35.325 m)/(25 revolutions) = (1.413 m)/revolution
πd = 1.413
d = 1.413/π = 0.45 m
