Step-by-step explanation:

The x-intercept is the point where the graph touches the x-axis, which means y=0. So let's set y=0 in your equation, and we receive

(x-5)^2 + (0+12)^ = 169

which means

(x-5)^2 = 25

Solve this, and get x=10 or x=0.

This means the x-intercepts are (10,0) and (0,0).

Try doing the same for y.

Where is water found in... lithosphere, asthenosphere, the mental, or earths core?

erica [24]

Answer:

Water is stored in the following places: The lithosphere (the solid outer crust and upper mantle). In oceanic crust it is stored within the rock structure which it is composed of and in continental crust it is also found in rocks, minerals, and also in clay and as groundwater.

I say the lithosphere.

Step-by-step explanation:

or it can be

But new research suggests a different origin for the oceans: they simply seeped out of the center of the Earth. The finding, published in Science, suggests that a reservoir of water is hidden in the Earth's mantle, more than 400 miles below the surface.

Help with 8 and 9??? Please help me out! Correct answers please

Ipatiy [6.2K]

Answer:

8. (-∞, 0) ∪ (0, 1/3) ∪ (1/3, ∞)

9. f(g(x)) = 4x/(1+6x)

Step-by-step explanation:

8. For f(g(x)) to be defined, g(x) must be defined and f(g(x)) must be defined.

g(x) will be defined for all x≠0. f(g(x)) will be defined for g(x)≠4. Solving g(x)=4, we find the value of x is 1/3. (The answer choices give a clue.)

So, the domain of f(g(x)) is all x that is not 0 or 1/3. Only one answer choice makes those particular exclusions:

(-∞, 0) ∪ (0, 1/3) ∪ (1/3, ∞)

9. Substituting the definition of g(x) into the expression for f(x), we get ...

$\displaystyle (f\circ g)(x)=f(g(x))=\frac{2}{g(x)+3}=\frac{2}{\frac{1}{2x}+3}\\\\=\frac{2}{\left(\frac{1+6x}{2x}\right)}\\\\(f\circ g)(x)=\frac{4x}{1+6x}$

Which of the following numbers are in the domain of the function? Select three that apply.

kipiarov [429]

Answer:

-15.2, -8, and -2

Step-by-step explanation:

Hello There!

If you didn't know the domain is the set of x values of a function

in the given function the domain could represented like this

x ≤-2

so anything that is -2 or less than -2 is considered a domain of the function

( how we found the set of x values: it was found by looking at the function. The function starts at (-2,-1) and goes up to the right with a constant rate of change.) This meaning that the domain could be represented by x ≤-2

-8 is less than -2 therefore it is a domain of the function

- 15.2 is less than -2 therefore is is a domain of the function

-2 is equal to -2 therefore is is a domain of the function

-1 is not less than -2 therefore it is not a domain of the function

2.5 and 10 are also not less than -2 therefore they are not domains to the function
