Find the value of X express each answer as a decimal rounded to the nearest tenth.

Mathematics
1 answer:
VMariaS [17]3 years ago
3 0

Answer:

x = 15.6

Step-by-step explanation:

use the pythagorean theorem:

a² + b² = c²

a = 9

b = x

c = 18

(9)² + x² = (18)²

81 + x² = 324                    subtract 81 from both sides

x² = 243                            take the square root of both sides

x = √243

x = 15.6

Please help! I will gift you brainiest in reward.
shepuryov [24]

Answer:

<h2>Graph D</h2>

Step-by-step explanation:

When the process starts, the water is flowing slowly, since there is only 1 valve open. That represents the part on this where the line is going almost horizontally.

When the operator opens the second valve also, then there will be more water released at once, which means that the water will come out faster, and take less time. That represents the middle part of the line, which is almost vertical.

When the operator shut's down the second valve, then the process gets slower, and that represents the part which is going slow again. And that represents the 3rd part, where the line is going almost horizontal again.

write two linear functions, f(x) and g(x). For example, f(x)= 3x-7 and g(x)= -2x+5. Then see whether f(x) - (-g(x)) is equivalen
sweet [91]

Answer:

the two expressions are equivalent.

Step-by-step explanation:

We know that f(x)= 3x-7 and g(x)= -2x+5, therefore:

f(x) - (-g(x)) = 3x-7 - ( +2x-5) = 3x - 7 - 2x + 5 = x -2

f(x) + g(x) = 3x-7 -2x + 5 = x - 2

Therefore,  f(x) - (-g(x)) is equivalent to f(x) + g(x).

Another way to check that the two expressions are equivalent is by solving the parenthesis:

f(x) - (-g(x)) →  f(x) + g(x)

Therefore, the two expressions are equivalent.

Answer: Second Option

f (x)=\frac{2}{x} and g(x)=\frac{2}{x}

Step-by-step explanation:

If we have a function f(x) and its inverse function f ^ {- 1} (x) = g (x)

Then by definition:

(fog) (x) = (gof) (x) = x

Notice that the inverse of the function f (x)=\frac{2}{x} is f ^ {- 1}(x)=\frac{2}{x}

then:

If f (x)=\frac{2}{x} and g(x)=\frac{2}{x}

Then:

(fog) (x) =\frac{2}{\frac{2}{x}}

(fog) (x) =\frac{2x}{2}

(fog) (x) =x

The answer is the second option
