Answer:

Option C, 0 ≤ x ≤ 12

Step-by-step explanation:

the domain of a function is the set of inputs accepted by the function so all possible x values.

Since x-axis is time, time can never be negative

so the lowest x value is 0

the heights x values is the x intercept which is 12

hence option C

Ley me know if you have any questions!!!

Answer:

C. 0 ≤ x ≤ 12

Step-by-step explanation:

The domain is the horizontal extent of the graph. The "reasonable domain" is the set of values of the independent variable for which the function makes sense.

<h3>values of interest</h3>

Here, the graph is showing the gallons remaining in a pool after x minutes. In general, we're not interested in gallons for negative minutes. Nor are we interested in negative gallons.

<h3>domain of interest</h3>

The only part of the graph that makes any sense in this situation is the part of it in the first quadrant, where <em>y and x are both non-negative</em>. The values of x for this to be true are ...

0 ≤ x ≤ 12

You are given that cos(A)=−35, with A in Quadrant II, and cos(B)=817, with B in Quadrant I. Find cos(A−B). Give your answer as a

cos (A - B) is 36/85

<h3>How to simply the identity</h3>

Expand cos(A - B) with the identity

You get, cos(A - B) = cos(A) cos(B) + sin(A) sin(B)

Since A is in quadrant II, so sin(A) > 0,

B is in quadrant I, so sin(B) > 0.

Using the Pythagorean identity, we get

cos²(A) + sin²(A) = 1

Make sin A the subject of formula

$sin(A)^{2}$ = ( $\sqrt{(1 - (-3/5}$ )²)

Find the square root of both sides, square root cancels square

$sin A$ = 4/5

Repeat the same for the second value

$sin A^{2} = \sqrt{(1- 8/17)^2}$

$sin A$ = 15/17

Substitute values into cos(A - B)

cos(A - B) = cos(A) cos(B) + sin(A) sin(B) = (-3/5) * 8/17 + 4/5 * 15/17

cos (A - B) = 36/85

Therefore, cos (A - B) is 36/85
