Answer:
slope = - 
Step-by-step explanation:
the slope of the secant line in the closed interval [a, b ] is
slope = 
here [a, b ] = [1, 4 ]
f(b) = f(4) = -
+ 5 = - 16 + 5 = - 11
f(a) = f(1) = -
+ 5 = - 2 + 5 = 3
slope =
=
= - 
Answer:
3
Step-by-step explanation:
Since the shelves are 75.5cm long, the total length she would be needing is 75.5cm × 6 = 453cm
Now, the length of the wood she is using is 180cm, to get enough length to make the shelves, we would need to divide 453cm by 180cm which gives a value of around 2.51
This is approximately equal to 3 when rounded up to the nearest whole number.
