=======================================================

Explanation:

Let x be the unknown positive integer.

The square roots of x are [tex]\sqrt{x}[/tex] and [tex]-\sqrt{x}[/tex], representing the positive and negative square roots respectively.

Taking the difference of those means we subtract:

[tex]\text{PositiveRoot}-\text{NegativeRoot} = \sqrt{x} - (-\sqrt{x}) = \sqrt{x}+\sqrt{x} = 2\sqrt{x}[/tex]

Set that equal to 40 and solve for x

[tex]2\sqrt{x} = 40\\\\\sqrt{x} = 40/2\\\\\sqrt{x} = 20\\\\x = 20^2\\\\x = 400[/tex]

Therefore, the integer we're after is 400.

The positive square root of such is [tex]\sqrt{x} = \sqrt{400} = \sqrt{20^2} = 20[/tex]

And the negative square root is [tex]-\sqrt{x} = -\sqrt{400} = -\sqrt{20^2} = -20[/tex]

The difference of which is:

(Positive Root) - (Negative Root) = 20-(-20) = 20+20 = 40

This helps confirm the answers.

Answer:

what is your question?

Step-by-step explanation:

The magnitude of the volume of the balloon increases at a faster rate than

the radius of the balloon.

Reasons:

The rate at which the volume of the balloon is increasing, [tex]\dfrac{dV}{dt} = 15 \ cm^3/s[/tex]

The initial volume of the balloon, V = 30 cm³

The rate of change of the volume of the balloon with radius is given as follows;

[tex]\dfrac{\Delta V}{\Delta r}= \dfrac{V_2 - V_1}{r_2 - r_1}[/tex]

[tex]Volume \ of \ the \ balloon, \ V = \dfrac{4}{3} \cdot \pi \cdot r^3[/tex]

[tex]V = 30 + \dfrac{dV}{dt} \times t[/tex]

∴ V = 30 + 15·t

At t = 0, V = 30 cm³

Where;

[tex]r =\sqrt[3]{ \dfrac{3 \cdot V}{4 \cdot \pi} }[/tex]

When V = 30

The radius, r ≈ 1.93 cm.

At t = 10 s., we have;

V = 30 + 15 × 10 = 180

At t = 20 s., we have;

V = 30 + 15 × 20 = 330

Therefore;

Between 0 s. and 10 s., we have;

Rate of change of the volume of the balloon with respect to the radius of the balloon to the nearest centimeter, between 0 s and 10 s is 96 cm³/cm.

Between 10 s. and 20 s., we have;

Between 10 s. and 20 s. the rate of change is approximately 190 cm³/cm.

Therefore;

The rate of change of the volume of the balloon with respect to radius is not constant, but increases as the volume of the balloon increases.

Answer:

x= -11

Step-by-step explanation:

Rearrange terms

[tex]-1=\frac{5+x}{6} into -1=\frac{x+5}{6}[/tex]

Multiply all terms by the same value to eliminate fraction denominators

[tex]-1=\frac{x+5}{6} \\6(1)=6(\frac{x+5}{6} )[/tex]

Cancel multiplied terms that are in the denominator

[tex]6(-1)=6 (\frac{x+5}{6} )6(-1)=x+5[/tex]

Multiply the numbers

[tex]6(-1)=x+5\\-6=x+5[/tex]

Subtract 5 from both sides of the equation

Step-by-step explanation:

Answer:

The graph is linear and shaded below the line.

Step-by-step explanation:

It looks like the graph is linear, since the line is straight and continues on forever in both directions. It's not quadratic or absolute value, since quadratic graphs are curved and absolute value graphs branch off in two directions.

If you look at the Desmos graph attached, the shade is below the line, not above the line.

Finally, (0, 0) is not a solution since this point is not part of the shaded section of the graph.
