For this case, we have that the polygon shown in the figure is composed of four rectangles.


1st rectangle:

It is found in the quadrant formed by the negative axis of the "x" coordinate and the positive axis of the "y" coordinate. This rectangle measures 5 units horizontally and 3 units vertically.

A1 = 5 * 3\\A1 = 15\ square\ units

2nd rectangle:

It is found in the quadrant formed by the positive axis of the "x" coordinate and the positive axis of the "y" coordinate. This rectangle measures 4 units horizontally and 2 units vertically.

A2 = 4 * 2\\A2 = 8\ square\ units

3rd rectangle:

It is located in the center of the four quadrants. This rectangle measures 5 units horizontally and 2 units vertically.

A3 = 5 * 2\\A3 = 10\ square\ units

4th rectangle:

It is in the middle of the quadrant formed by the positive axis of the coordinate "x" and the negative axis of the coordinate "y", and the quadrant formed by the negative axis of the coordinate "x" and the negative axis of the coordinate "Y".

A4 = 3 * 4\\A4 = 12\ square\ units

Thus, the total area is given by the sum of the partial areas.

At = 15 + 8 + 10 + 12\\At = 45\ square\ units

Answer:

At = 45\ square\ units

Option B

A water tank is being filled by pumps at a constant rate. The volume of water in the tank V, in gallons, is given by the equatio
mamaluj [8]

Answer:

65 gallons per minute

Step-by-step explanation:

The total volume of the tank at any given time is given by the equation:

V(t) = 65t + 280

In order to find the rate of change of volume, we can simply differentiate this equation with respect to time. This will give us the rate of change of the volume or the rate at which water is being pumped into the tank.

Differentiating the above equation we get:

V'(t) = 65

So we can see that the rate at which water is being pumped into the tank is 65 gallons per minute

Number 8 please it will help a lot
pickupchik [31]
Well it all depends on the object you are using but in this case lets say remote control cars. You can have an example like "we drove the car around the building twice. the first time it was -8 than how fast it was supposed to go. the second time it was 9. In which round was the car faster?" I dont think i helped very much but i hope i did
