Height of the triangle with AB as base = 2 – (–3) => 5 

<span>Area = (1/2) * base * height => (1/2) * 8 * 5 ==> 20 sq. units. </span>

First, consider (0,2) and (8,2).  The y-value is the same for both points.  x ranges from 0 to 8, so the length of this horizontal side of the triangle is (8-0), or 8.

Again, this horiz. side has a y-value of 2.
The third point is (4,-3).  Therefore the vertical distance from the horizontal line to the third point is 2 - (-3), or 5.

Thus, the "base" of the triangle is 8 and the "height" is 5.

The area is  A = (bh)/2.  Substitute the values 8 and 5.  Simplify your result.  Answer:  20 square units.

Calculates the total amount E, in dollars, that she earns for working h hours using the equation E = 10h
GrogVix [38]

So your equation is E=10h.

We know E is equal to 1 so let's plug that is.

1=10h

Now we just solve it.

1=10h    Divide each side by 10

.1=h

Boom!

She has to work .1 hours or 1/10 of an hour to earn 1 dollar.



Hope I helped!

LOTS OF POINTS + BRAINLIEST
Gekata [30.6K]

Answer:

The list od prime number is a quadratic sequence, each time going up by n + 2. for example, 1, 4, 9, 16, 25. they are going up by 3, then + 2 and add 2 every step. The sequence is always going up by an odd number. a negative number take away a negative number always gives you a positive number, likewise, adding does too. Therefore, you can not get both of them to fit into the sequence of increasing odd numbers.

         __________________
x²+2  l 4x^4         +2x²     -2
         l  4x^4        +8x²
           --------------------
                            -6x²     -2

so the answer is (4x^2-6) \frac{10}{x^2+2}
