Answer:
<em>The area of the triangle DEF is 10.</em>
Step-by-step explanation:
<u>Area of a Triangle:</u>
A triangle of base B and height H (both must be perpendicular) has an area of:

The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.
This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:
B=3-(-2)=3+2=5
Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.
H=2-(-2)=4
With these two values, we calculate the area:

The area of the triangle DEF is 10.
They are all not functions
One pear weighs 6 oz, you have 11 pears you multiply 11 by 6 getting 66 oz divided by 16 equals 4.25 lbs. Because there are 16 oz in 1 pound.
answer: No
Answer:
-36/15
Step-by-step explanation:
If the indefinite integral of f(x)dx is F(x), then your integral from 1 to 5 is ...
F(5) -F(1) = 36/15
The integral in the reverse direction is ...
F(1) -F(5) = -(F(5) -F(1)) = -36/15
Answer:
A quadratic equation is an equation of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. One absolute rule is that the first constant "a" cannot be a zero.
