Answer:

The function is discontinuous at x = 1.

The value of the function is never negative.

The value of the function at x = -1 is 0

Step-by-step explanation:

Given is a graph of   a function first a straight line, followed by a semi circle centred at the origin and another piece of straight line not connected to the other graph.

We can see that the funciton is discontinuous at x=1 since

right limit = 1 and left limit =0

x=1 is in the domain .

f(-1) =0 is right

But f(1) =0 is incorrect

Thus correct options are

The function is discontinuous at x = 1.

The value of the function is never negative.

The value of the function at x = -1 is 0

Take a factor out of the square root:
Allisa [31]

Answer:

Question A)

=\sqrt{6}x

Question B)

=3a\sqrt{a}

Question C)

=5\sqrt{2}b^2

Step-by-step explanation:

A)

We are given:

\sqrt{6x^2}\, \text{ where } x\geq 0

We can rewrite the expression:

=\sqrt{6}\cdot \sqrt{x^2}

The square root and square will cancel each other out. Thus:

=\sqrt{6}x

B)

We are given:

\sqrt{9a^3}

Rewrite:

=\sqrt{9}\cdot \sqrt{a^3}

Note that the square root of 9 is simply 3. We can also factor the second part:

=3\cdot \sqrt{a^2\cdot a}

Rewriting:

=3\cdot\sqrt{a^2}\cdot\sqrt{a}

Simplify:

=3a\sqrt{a}

C)

We are given:

\sqrt{50b^4}

Rewrite. Note that 50 = 25(2):

=\sqrt{25}\cdot \sqrt{2}\cdot \sqrt{b^4}

Simplify. We can rewrite the factor as:

=5\cdot \sqrt{2}\cdot \sqrt{(b^2)^2}

The square and square root will cancel out. Thus:

=5\sqrt{2}b^2

Can someone help me with this
jarptica [38.1K]

The answer is:

x=-8

Because:

If you pick a number(-8) to fill in the equation written below

5x+20+5x=5x-20

After applying the -8 to x you get

-40+20-40=-40-20

When you simply the both sides you get

-60=-60

And that’s right -60 is equal to -60!

Which equation can be used to solve for b?<br> B<br> 5 cm<br> 10 cm<br> 30°
kati45 [8]

The Question is Incomplete The complete question with figure is below.

Answer:

Therefore the equation to solve for b is

\tan 30 = \dfrac{5}{b}

Step-by-step explanation:

Given:

In Right Angle Triangle ABC

∠C = 90°

BC = 5 cm

AB = 10 cm

∠A = 30°

To Find:

b = ?

Solution:

In Right Angle Triangle ABC Tangent identity we have

\tan A = \dfrac{\textrm{side opposite to angle A}}{\textrm{side adjacent to angle A}}

Substituting the values we get

\tan 30 = \dfrac{BC}{AC}\\\\\tan 30 = \dfrac{5}{b}

Therefore the equation to solve for b is

\tan 30 = \dfrac{5}{b}
