Answer:
6
Step-by-step explanation:
Any circle in the form

Where r^2 is the radius squared, so


Answer:
<u>v = √(LT/m)</u>
Step-by-step explanation:
Given :
Multiply both sides with L :
- T × L = mv²/L x L
- LT = mv²
Divide both sides by m :
- LT × 1/m = mv² × 1/m
- LT/m = v²
Take the square root on each side :
- √v² = √(LT/m)
- <u>v = √(LT/m)</u>
Answer:
the answer is A
Step-by-step explanation:
Answer:
f(x) = y
Step-by-step explanation:
f(x) always equals y, so the equation would be y = 7. therefore, I am pretty sure that x = y, but you may want to wait to ask your teacher. If there is more detail, message me!
Answer:
(3.8, 6.8)
Step-by-step explanation:
Point B:
Has coordinates (x,y)
AB and BC form a 2:3 ratio.
This means that:


We apply this both for the x-coordinate and for the y-coordinate.
x-coordinate:
x-coordinate of A: 3
x-coordinate of C: 5
x-coordinate of B: x




y-coordinate:
y-coordinate of A: 4
y-coordinate of C: 11
y-coordinate of B: y




Thus the correct answer is:
(3.8, 6.8)
