ANSWER

All real numbers greater or equal to -3.

EXPLANATION

The domain of the given function are values of x that make the function defined.

We can see from the graph that, the domain are x-values greater than or equal to -3.

In other words, we can find a corresponding y-value for all x-values greater than or equal to -3.

The correct answer is option D.

What is the solution set for 3x>6?

zalisa [80]

Isolate the x

divide 3 from both sides

3x/3 > 6/3

x > 6/3

x > 2 is your answer

Note: because you are not dividing by a negative number, you do not need to flip the sign

hope this helps

For each value of u, determine whether it is a solution to -15 = 1 - 4u

Alona [7]

Answer:

1. No

2. No

3. No

4. Yes

Step-by-step explanation:

Plug each option into u then solve the equation and see if the answer matches -15.

Ex. -15 = 1 -4 (2)

-15 = 1 -8

-15 = -7

-15 does not equal -7 therefore it is false. Use Pemdas to solve.

the length of the shadow of a pole on level ground increases by 90m when the angle of elevation of the sun changes from 58 degre

Anarel [89]

Answer:

The height of the pole is 167 m

Step-by-step explanation:

The given parameters are;

Increase in the length of the shadow = 90 m

Initial angle of elevation of the Sun = 58°

Final angle of elevation of the Sun = 36°

We have a triangle formed by the change in the length of the shadow and the rays from the two angle of elevation to the top of the pole giving an angle 22° opposite to the increase in the length of the shadow

We have by sin rule;

90/(sin (22°) = (Initial ray from the top of the pole to the end of the shadow's length)/(sin(122°)

Let the initial ray from the top of the pole to the end of the shadow's length = l₁

90/(sin (22°) = l₁/(sin(122°)

l₁ = 90/(sin (22°) ×(sin(122°) = 283.3 m

Therefore;

The height of the pole = 283.3 m × sin(36°) = 166.52 m

The height of the pole= 167 m to three significant figures.
