Answer:

Last Option: (-∞, 4) U (4, ∞)

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

We see that our x-values span all numbers except x = -4. Therefore, it is not included in our domain:

(-∞, 4) U (4, ∞)

Answer:

$x = 13.8$

Step-by-step explanation:

Given

See attachment for triangle

Required

Find x

To find y, we make use of the relationship between sides lengths 11 & x and angle 37

The relationship is:

$cos(37) = \frac{11}{x}$

i.e.

$cos(\theta) = \frac{Adjacent}{Hypotenuse}$

Make x the subject

$x = \frac{11}{cos(37)}$

$x = \frac{11}{0.7986}$

$x = 13.7741$

$x = 13.8$ -- approximated

Which is 2/3 of 18 <br>A. 27<br>B. 8<br>C. 12<br>D. 6

ahrayia [7]

Answer:

C. 12

Step-by-step explanation:

We know you have the number 18 and the fraction 2/3. The problem is we want to find out what 2/3 of 18 is. Well, if 18 divided by the denominator of that fraction (3) is 6 than we just add 6 because the question is asking for 2/3 NOT 1/3.

Are the graphs 8x+3y=6 and 8x-3y=6 perpendicular

Alla [95]

Lines are perpendicular if the slope of one is the negative reciprocal of the other. In this case the slopes are -8/3 and 8/3, so while negative they are not reciprocal. So no, the two lines intersect but are not perpendicular.
