Answer:
make me brainliest i have been subbed for a couple yrs not joking
Step-by-step explanation:
X=-x
add x to both sides
2x=0
x=0
Answer:
D: r=1/2 sqrt(P/πI)
Step-by-step explanation:
P=4πIr²
We want to solve the equation for r
First divide each side of the equation by 4πI
P/4πI =4πIr²/4πI
P/4πI =r²
Then we need to take the square root of each side. Normally we would take the ± square root, but distance cannot be negative.
sqrt(P/4πI) = sqrt(r²)
sqrt(P/4πI) = r
Notice that there is a 4 in the denominator. sqrt(4) = 2
sqrt(P/πI)* 1/sqrt(4) = r
sqrt(P/πI)* 1/2 = r
1/2 sqrt(P/πI) = r
may I ask if these questions' answer are always 2... or they can be other numbers too
38 mm to m
38 mm * (0.001 m / 1 mm)
**cancel mm units**
38 * (0.001 m / 1)
0.038 m
you're correct
