Answer:
the original price is $7.89
the price on sale is $6.44
i hope this helps
Step-by-step explanation:
divide $12.88 by 2 to get the price of one of those comic books on sale which gives you $6.44
if you want the original price you just add $1.45 to $6.44 and then thats the price before the sale.
The question is missing the detail, it is to find the dimensions of the largest field that can be fenced in.
The formula for area is : A = xy
The perimeter of the fencing is equal to the sum of two widths and the length: 2x + y = 3000
Now, solve the second equation: y = 3000 – 2x
When you plug this expression to the formula for the area, we will get:
A = x (3000-2x) = 3000x – 2x^2
Next take the derivative and equal it to 0: dA/dx = 3000 – 4x = 0
Now solve for x, it will give us 750.
Find the second derivative.
d^2 A / dx^2 = -4
since we have a negative result, x = 75- is a maximum. Then plug this in to x:
3000 – 2 (750) = 1500. The largest field will measure 750 ft by 1500 ft.
Answer:
-15
Explanation:
-5 / 5 = -1
-1 x 19 = -19
-19 + 4 = -15
