Answer:
See below
Step-by-step explanation:
Regularly, 1.25
Now,0.5
So,

So, the percentage of decrease price is 60%.
The x -intercepts occur when f(x) =0
So,
(x-4)^2 = x^2 -8x + 16 -3 =0
x^2 -8x + 13 =0
Solving by the quadratic formula
x1 = 5.7321
x2 = 2.2679
This is a trapezoid and the trapezoid formula is b1 plus b2/ 2 times height.
17 plus 5 is 22. Divided by 2 is 11.
Now, we have to multiply 11 by the height : 5.
11 times 5 is 55 and that is your area. 55 units squared.
The total number of calories for 18 cups of milk is 1620 calories.
If two cups of milk is 180 calories then divide 180/2 to find the unit rate.
Then multiply 90 by the number of cups (18) and then you get the total number of calories for that many drinks.
