Answer:
(x - 11)² + y² = 25
Step-by-step explanation:
First find the center
O = ( (15 +7 / 2), (-3 + 3)/2 )
O = (11, 0)
Then find the radius squared
use the distance formula from the center to either end point of the diameter
r² = (15 - 11)² + (-3 - 0)²
r² = 16 + 9
r² = 25
Formula for circle
(x - h)² + (y - k)² = r²
(h, k) is the center = (11, 0)
The equation is
(x - 11)² + y² = 25
Answer:
9.73 cm to 2 DP
Step-by-step explanation:
Total of the lengths involved = 7*9.4 + 5*10.2
= 116.8 cm
So the mean of the 12 fingers
= 116.8/12
= 9.73 cm to 2 DP.
Seven hundred and fifty one thousand
I hope this helps
The formula is K = v^2 /2
You are told K = 32.
Replace K and solve for v:
32 = v^2 / 2
Multiply each side by 2:
64 = v^2
Take the square root of both sides:
v = √64
v = 8 meters per second.
I’m Not good at This but I’ll try to help ;c
