Answer:
radius = 4units
diameter = 8units
Step-by-step explanation:
The radius is the distance from the midpoint of a circle to any point on the side of the circle. In this case, the radius is, 4units. The diameter is twice the radius and is 8 units.
Answer: 28/32 but converted its 7/8. My work is kinda messy sorry. But this is my work.

you put in -6 for m and -2 for n

the 2/2 =1 but one is negative so it's -1

negative times a negative is a positive
To evaluate the value of y if x=7, given that function is such that y=2x^2-3x+3, we shall have:
f(7)=2(7)^2-3(7)+3
f(7)=2(49)-3(7)+3
f(7)=98-21+3
f(7)=80
Hence we conclude that when x=7, y=80
