the variables a and B are positive numbers. drag and drop each coordinate point to match the correct quadrant.
inessss [21]

Answer:

Hence,

Quadrant I    --------------- ( a , b)

Quadrant II   --------------- ( -a , b)

Quadrant III  --------------- ( -a , -b)

Quadrant IV --------------- ( a , -b)

Step-by-step explanation:

There our four quadrant divided by the x-axis and y-axis.

So the variables according to the quadrant are given below.

Quadrant I : Both the coordinates are positive.

Quadrant II : x-coordinate is negative and y-coordinate it is positive.

Quadrant III : x-coordinate is negative and y-coordinate it is negative.

Quadrant IV : x-coordinate is positive and y-coordinate it is negative.

Hence,

Quadrant I    --------------- ( a , b)

Quadrant II   --------------- ( -a , b)

Quadrant III  --------------- ( -a , -b)

Quadrant IV --------------- ( a , -b)

Find the island height of a pyramid with a volume of 432 ft^3 if the base is a square with a side length of 12 ft. Round to the
dmitriy555 [2]

So the picture below shows what the slant height is. It also shows that the pyramid can form a right triangle, in which we can use the pythagorean theorem, which is leg^2+leg^2=hypotenuse^2 .

But first, we have to find the height of this pyramid. The volume formula for a square pyramid is A=\frac{lwh}{3} . Since we know its a square pyramid, the length and width are going to be the same (12 ft), and we know that the volume is 432 ft^3. Using this info, we can solve for the height:

432=\frac{12*12*h}{3}\\ 1296=12*12*h\\ 1296=144*h\\ 9=h

So now we can use the pythagorean theorem (remember to split the 12 by 2, since the right triangle has only half the length of the base). Our equation will be solved as such:

6^2+9^2=s^2\\ 36+81=s^2\\ 117=s^2\\ 10.8=s

In short, the slant height is 10.8 ft.
