Answer:
1. A. AC=3IN
2. D AND C
Step-by-step explanation:
If you'd graph this function, you'd see that it's positive on [-1.5,0], and that it's possible to inscribe 3 rectangles on the intervals [-1.5,-1), (-1,-0.5), (-0.5, 1].
The width of each rect. is 1/2.
The heights of the 3 inscribed rect. are {-2.25+6, -1+6, -.25+6} = {3.75,5,5.75}.
The areas of these 3 inscribed rect. are (1/2)*{3.75,5,5.75}, which come out to:
{1.875, 2.5, 2.875}
Add these three areas together; you sum will represent the approx. area under the given curve on the given interval: 1.875+2.5+2.875 = ?
Answer:
x = 12
Step-by-step explanation:
Complementary angles add up to have a sum of 90 degrees. We can create an equation and solve for x.
3x + 6x - 18 = 90
~Simplify
9x - 18 = 90
~Add 18 to both sides
9x = 108
~Divide 9 to both sides
x = 12
Best of Luck!
These are the elements of the matrix
Elements of the first row are h11 h12 h13, of the second row h21 h22 h23.
Than we can conclude that element h23 worth 75.
Good luck!!!
Answer:
C) 14/4
Step-by-step explanation:
Multiply the amount of land per month by the number of months.
(2/4)(7) = 14/4 acres
