To solve this question we have to simplify each equation 1 by 1 :

First, let us do the equation in the problem:

8 + (n - 4) = n +4

Now let us review the answers:

A. Is equivalent because  8 + (n - 4) = n + 4

B.  Is equivalent because (8 - 4) + n = n + 4

C. Is equivalent because (8 + n) - 4 = n + 4

and D. is not equivalent because obviously 12 + n does not equal n + 4

If and , what is the domain of g(x) ÷ f(x)?

A.


B.


C.


D.

Answers

g(x)/f(x) will be simplified to (x+3)(x-3)/2-x^1/2,
which will give you [0,4) ∪(4, ∞).
Choice B

The domain of g(x)  ÷ f(x) is [0, 2) U (2, ∞). Option D

How to determine the domain

We must take into account the restrictions on both g(x) and f(x) in order to determine the domain of the function h(x) = g(x)/f(x).

There are no restrictions on x for g(x) = x² - 9. This is to avoid a zero denominator.

The square root function needs the parameter (x) to be non-negative (x 0) for f(x) =[tex]2 - x^(^1^/^2^)[/tex] to work. We also exclude out x = 2 because the denominator cannot be zero.

Combining these restrictions, the intersection of the g(x) and f(x) domains yields the domain of h(x), which is:

Domain of h(x) in interval notation is [0, 2) U (2, ∞).

Absolute value can be seen as the distance between a number and zero. It is always a positive number. 5 is 5 units away from 0. |5| = 5, and |-5| would also be 5. It's important not to get absolute value confused with opposites.

A right triangle has side lengths of 3cm, 4cm, and 5cm. What is the sine of the angle opposite the side of length 4cm

Answers

In a right triangle, the sine of the angle opposite the side of length 4 cm is 0.8 cm.

In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite the angle to the length of the hypotenuse.

The angle opposite the side of length 4 cm can be calculated as:

The hypotenuse is the side of length 5 cm.

The calculation of the sine of the angle can be calculated using the formula:

[tex]Sine = \dfrac{Opposite}{hypotenuse}[/tex]

Substitute the value in the given formula.

[tex]Sine(A) = \dfrac{4}{5}[/tex]

Sine(A) = 0.8

So, the sine of the angle opposite the side of length 4 cm is 0.8 cm.

Please help with this please

Answers

Answer:

104°

This is because there are two lines, each line is 180°, so both is equal to 360°. Angle y and the one with 76° are the same, so that should mean angle z and x are the same. So you subtract 152° from 360° (76° doubled) and you get 208° leftover. Now to get the last two angles, you divide 208° by 2, so each angle should be 104°. :))
