Answer:
3.24m
Step-by-step explanation:
SOH
sin(26)=O/7.4
O=7.4 sin(26)
O=3.24 (3sf)
Anything between the decimal and last non-zero digit
so 00025 are significant
the 0 in front is insignificant because it could be
00000.00025
zeroes after the 25 don't matter becasue it could be
0.000250000000 and it wouldn't change
the sig figs are 00025
Answer: 
Step-by-step explanation:
Given
A gym owner has purple and white weights that measure 10 kg and 6 kg each
respectively.
They weigh 84 kg in total
suppose there x purple and y white weights
Thus, there are 3 purple and 9 white weights.
Answer:
L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt
Step-by-step explanation:
Arc length of a parametric curve is:
L = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt
x = t + cos t, dx/dt = 1 − sin t
y = t − sin t, dy/dt = 1 − cos t
L = ∫₀²ᵖⁱ √((1 − sin t)² + (1 − cos t)²) dt
Or, if you wish to simplify:
L = ∫₀²ᵖⁱ √(1 − 2 sin t + sin²t + 1 − 2 cos t + cos²t) dt
L = ∫₀²ᵖⁱ √(3 − 2 sin t − 2 cos t) dt
