M= 276 31+276=307.
307-31=276 that’s how I found M
A
substitute x = 3h into f(x)
f(3h) = 2(3h)² + 3(3h) - 4 = (2 × 9h²) + 9h - 4 = 18h² + 9h - 4
Answer:
Option B
Step-by-step explanation:
Formula to be used to calculate the length of an arc,
Length of arc = 
Here, θ = Angle subtended at the center by the arc
r = radius of the circle
By substituting values in the formula,
s = 


Therefore, Option B will be the answer.
Answer:
43.6 amp
Step-by-step explanation:
Given
A 40 amp fuse carries a temporary 9 % current overload.
9% current overload means that whatever will be the normal current carrying capacity of fuse, during overload it carries 9% more than that.
Current carrying capacity of fuse is 40 amp.
during overload it carries 9% more
over load current = 9% of 40 amp = 9/100 *40 = 3.6 amp
total current flowing through fuse during overload = 40 amp + 3.6 amp
= 43.6 amp (answer)
