area = pi * r^2
here, the radius is 2 as its the diameter/2.
so the area is 4pi.
circumference = 2*pi*r.
so the circumference is 4pi as well.
If
, then any ordered pair would satisfy the equation.
Since we're not given the ordered pairs, then this is the only information I can give to you.
Answer:
B y=8x
Step-by-step explanation:
A proportional relationship must go through the point x=0, y=0 and be in the form y=kx where x is a constant
A) y = x^8
B) y = 8 x
C) y = x^8 + 8
D) y = 8 x + 8
The only points that is in the form y= kx is option B
C and D do not go through x=0, y=0 and A is not in the form y=kx where k is a constant
Answer:
Gradient of A: 2
Gradient of B: -1
Step-by-step explanation:
Gradient = change in y/change in x
✔️Gradient of A using two points on line A, (2, 5) and (0, 1):
Gradient = (1 - 5)/(0 - 2) = -4/-2
Simplify
Gradient of A = 2
✔️Gradient of B using two points on line B, (0, 5) and (5, 0):
Gradient = (0 - 5)/(5 - 0) = -5/5
Simplify
Gradient of B = -1
Step-by-step explanation:
The reason is because it is not just 6 it is - 6 so when there are two negative numbers they don't subtract they add if it was 6n then it was to be subtracted
21m - 11n + 2m
23m - 11n
