<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 

Answer:
5 3/4
Step by step explanation:
Find a common denominator in this case is 4 so instead of adding 2 1/2 to 3 1/4 it’s going to be 3 1/4 + 2 2/4 which gets you 5 3/4
So what you do for distributive property is take #1 for example: 3(2x + 10) = 54. When there’s a parenthesis, you take the outside number which is the 3 times the numbers inside the parenthesis. So after doing that first step you should get 6x + 30 = 54. Now you want to get rid of the 30 so you do 30-30=0 but you have to do it on the other side as well. So subtracting 30 on both sides you should have 6x = 24. Now you want to get x by itself. The opposite of multiplying is dividing so you divide 6 from 6x. So the same on the other side. You get your answer x=4 if you did everything correct

Step-by-step explanation:
Let's convert the two fractions.
The two categories are now closest to -0.6 and closest to 0.8.
Closest to -0.6 or -3/5: -0.2, -4/5,
Closest to 0.8 or 4/5: 0.6, 2/5
