The cost of fencing (C)
The cost is calculated as:
Let:
So, we have:
<em>The question cannot be solved further since the dimension of the fence is not given</em>
<em>If you know the dimension, calculate the fence perimeter and substitute the value for x</em>
Answer:
<h2>(a) 5,050 psi.</h2><h2>(b) 5,051.3 psi.</h2><h2>(c) 5,180 psi.</h2><h2>(d) 4,920 psi.</h2>Step-by-step explanation:
The given function is
Where represents the accelerated strength in psi, and
represents 28-day standard-cured strength in psi.
Part a is about finding the y-value for
Therefore, the expected value of 28-day strength when accelerated strength is 2,500, is 5,050 psi.
Part b is about the y-value for
Part c is about the y-value for
Part d is about the y-value for
