The answer is 4.4102. We know the length of one side is 2.4 and the length of the other side is half of 7.4. If we use Pythagorean’s theorem to find the hypotenuse we get (7.4/2)^2 + 2.4^2 = X^2. By solving for x we get x= root( (7.4/2)^2 + 2.4^2). So x is approximately 4.41.

Which pipe configuration can deliver more water to

Stels [109]

Answer: One 8-cm pipe (Its is greater than the total area of of two 4-cm pipes)

Step-by-step explanation:

The area of a circle can be calculate with this formula:

$A=\pi r^2$

Where "r" is the radius of the circle.

We need to calculate the area of 8-cm pipe. In this case:

$r=8cm$

Then, substituting the radius into the formula, we get:

$A=\pi (8cm)^2\\\\A=201.06cm^2$

Now we must calculate the area of the two 4-cm pipes.

Since they are two pipes, the formula is:

$A=2\pi r^2$

In this case:

$r=4cm$

Then, substituting into the formula, we get:

$A=2\pi (4cm)^2\\\\A=100.53cm^2$

Therefore, since the area of one 8-cm pipe is greater than the total area of of two 4-cm pipes, we conclude that the pipe configuration that can deliver more water to residents is:

One 8-cm pipe

NEED HELP ASAP. ONLY ANSWER IF YOU CAN EXPLAIN THIS CORRECTLY

ss7ja [257]

Answer:

B. f(x) and g(x) have a common x-intercept.

Step-by-step explanation:

When x = 2 for g(x), the output is 0.

When x = 2 for f(x), the output is also 0.

So, that would mean that f(x) and g(x) have a common x-intercept.
