Answer:
This is going to be really long so sorry in advance :)). So i split the shape into two (so straight down).This therefore allows me to calculate the areas of both rectangles and add them together - (to give total area)
Area of A x(x^2-6)
=x^3-6x
Area of B
=(2x^3-5x^2-12x+14) (5x-14)
10x^4-28x^3-25^3-70x^2-60x^2+168x+70x-196
simplified: 10x^4-53^3-130x^2+238x-196
so add both areas to give total are:
=(x^3-6x) +(10x^4-53x^3-130x^2+238x-196)
=10x^4-52x^3-130x^2+232x-196
Thats it hope it helps :)
Step-by-step explanation:
The period is 5. Start at x = 0 and trace the curve until you reach the same height as when you were at x = 0 (which is y = 3). The function repeats itself over again once you get to x = 5.
The amplitude is 2.5 since it is half of the vertical distance from the peak y = 3 to the valley y = -2. This distance is 5 units, half of which is 2.5
Answer:
1.78 pints
Step-by-step explanation:
We need to find 4/5 of the total pints of paint she used, so we know how much blue paint she used. Then, we subtract that from the total pints of paint that she used.
She used 8.9 pints of both blue and white paint.
Therefore, the amount of blue paint she used is:
4 / 5 * 8.9 = 7.12 pints
The amount of white paint she used is therefore:
8.9 - 7.12 = 1.78 pints
If you take 2000 and subtract that by 500 for the childrens books that would equal 1500. So, the fiction and nonfiction books sum would have to be 1500. Since 850 plus 650 equals 1500, there would be 650 nonfiction books, 850 fiction books, and 500 children's books.
Hope This Helps!
