Answer:
This table represents a function
y is 1.3 times x
y=1.3x
Step-by-step explanation:
The variable for x is twenty eight
Answer: The square root of 69 is 8.3, which means it lies between the integers 8 & 9.
Step-by-step explanation: hope this helps
You didn't include the formula.
Given that there is no data about the mass, I will suppose that the formula is that of the simple pendulum (which is only valid if the mass is negligible).
Any way my idea is to teach you how to use the formula and you can apply the procedure to the real formula that the problem incorporates.
Simple pendulum formula:
Period = 2π √(L/g)
Square both sides
Period^2 = (2π)^2 L/g
L = [Period / 2π)^2 * g
Period = 3.1 s
2π ≈ 6.28
g ≈ 10 m/s^2
L = [3.1s/6.28]^2 * 10m/s^2 =2.43 m
I hope this helps you.
T=150+75h
T is total
The electrician has a set fee of $150 plus $75 for every hour he is there
75 per hour is the same thing as 75h
