To find the length of each side of the trapezoid, you need to use the distance formula.
AB = (-3,2) and (1,5)
BC = (1,5) and (7,-3)
CD = (7, -3) and (0, -2)
AD or DA = (0,-2) and (-3,2)
Now, just use the distance formula for each line. Doing so gives us:
AB = 5
BC = 10
CD = 7.071107...
DA or AD = 5
The height is AB, the first base is BC and the second base is CD. We can plug the values for these sides into the trapezoid area formula, which is A = base 1 + base 2 all over 2 times the height. Doing so gives us 37.5 units². Therefore, the answer to your query is 37.5 units². Hope this helps and have a nice day!

△ABC is a right isosceles triangle, the centers of two arcs are the midpoint of AB
mel-nik [20]

Answer:

  0

Step-by-step explanation:

Let's define 3 areas:

  • S = area of semicircle with radius 6 in (diameter AB)
  • T = area of quarter circle with radius 6√2 in (radius AC)
  • U = area of triangle ABC (side lengths 6√2)

The white space between the "moon" and the triangle has area ...

  white = T - U

Then the area of the "moon" shape is ...

  moon = S -white = S -(T -U) = S -T +U

The area we're asked to find is ...

  moon - triangle = (S -T +U) -U = S -T

__

The formula for the area of a circle of radius r is ...

  A = πr²

So, ...

  S = (1/2)π(6 in)² = 18π in²

and

  T = (1/4)π(6√2 in)² = 18π in²

The difference in areas is S -T = (18π in²) -(18π in²) = 0.

There is no difference between the areas of the "moon" and the triangle.

Graph the line with the slope -3/4 passing through the point (4,-1)
-Dominant- [34]

Answer:

Step-by-step explanation:

Plot the point (4, -1) in the 4th Quadrant.

The slope (-3/4) tells us what to do next:

With your pencil point initially on (4, -1), move it 4 units to the right, to (8, -1).

With your point initially on (8, -10, move it down 3 units, to (8, -4).  Plot (darken) (8, -4).

Draw a line through (4, -1) AND (8, -4)

Nina bought a computer mouse for $9.30.She paid with a $20 dollar bill how much money din she get back
Tpy6a [65]

Answer: \$10.7

Step-by-step explanation:

Given

Nina bought a computer mouse for $9.30

She paid a $20 dollar bill

The money she received is the difference between what is paid and the cost of the mouse i.e.

\Rightarrow 20-9.3\\\Rightarrow \$10.7

Therefore, she gets \$10.7 after deductions.

If the quadratic equation has the form y = ax 2and y = ax 2+ c, then their axis of symmetry must always be?
emmainna [20.7K]

9514 1404 393

Answer:

  x = 0

Step-by-step explanation:

When there is no linear term in the equation, the axis of symmetry is x=0.

__

The values 'a' and 'c' represent a vertical scale factor and a vertical translation, respectively. They do not change the axis of symmetry from that of the parent function, which is x=0.
