The inverse of Fx) is a function.<br> FOD<br> A. True<br> B. False
anastassius [24]
Not all functions have inverse functions. Those that do are called invertible. For a function f: X → Y to have an inverse, it must have the property that for every y in Y, there is exactly one x in X such that f(x) = y.

A rectangular pool is to be built on a lot that measures 20 m by 12 m. A wooden deck of uniform width, equal to the area of the
frutty [35]

The length and breadth(width) of the pool are

l\approx15.7m\text{ and }b\approx7.7m

Let

l=\text{length of the side of the pool}\\b=\text{breadth of the pool side}\\w=\text{the width of the strip of deck surrounding the pool}

From the question, we can build the following relationships

l+2w=20\\b+2w=12

subtracting to eliminate w (we do not even need it!)

l-b=8\\b=l-8

we can also build another relationship from the question. Since the area of the strip equals the area of the pool:

lb+lb=2lb=20\times 12\\lb=120

We have two unknowns, l and b. Eliminate b

lb=120\\l(l-8)=120\\l^2-8l-120=0

If we solve the quadratic equation for l, we get

l=4+2\sqrt{34}\approx 15.7m

and

b=l-8\\b=(4+2\sqrt{34})-8\\b=2\sqrt{34}-4\approx7.7m

The length and breadth(width) of the pool are

l\approx15.7m\text{ and }b\approx7.7m

Hey please help me asap
Harrizon [31]

Answer:

It's A.

Step-by-step explanation:

Since point C divides in the ratio 1:2, one of the coordinates has to be half of the other coordinate. 3 is half of the coordinate 6, which therefore makes it correct.
