Answer:

x2 − 16 is the difference of two squares

Step-by-step explanation:

x2 − 16 is the difference of two squares, given that 16 can be represented as a square in the form 4^2.

Then, x2 − 16 = x2 − 4^2.

ANSWER

{x}^{2} - 16

EXPLANATION

Difference of two squares refers to two square numbers (terms) that are subtracting.

Thus, difference of two squares is of the form;

{a}^{2} - {b}^{2}

Among the given options, the only expression we can rewrite as difference of two squares is

{x}^{2} - 16 = {x}^{2} - {4}^{2}

The first choice is correct.

What’s the value of x?<br> 3x-24=x+10
finlep [7]

Answer:

x=17

Step-by-step explanation:

3x-24=x+10

Carry over the like terms and put them together. Make the unknowns which are x the subject.

3x-x= 24+10

2x= 34

2x= 34/2

x= 17

Given the general form of the sinusoidal function, y = AsinB(x - C) + D, match the following items.
Jet001 [13]

Answer:

\Delta y = A (Amplitude) (Correct answer: 1)

\omega = B (Angular frequency) (Correct answer: 2)

x_{o} = C (Phase shift) (Correct answer: 3)

y_{o} = D (Vertical shift) (Correct answer: 4)

\frac{2\pi}{\omega} = \frac{2\pi}{B} (Period) (Correct answer: 5)

Step-by-step explanation:

The general form of a sinusoidal function is represented by the following characteristics:

y = \Delta y \cdot \sin \omega\cdot (x- x_{o}) + y_{o} (1)

Where:

\Delta y - Amplitude.

\omega - Angular frequency.

x_{o} - Phase shift.

y_{o} - Vertical shift.

x - Independent variable.

y - Dependent variable.

In addition, we know that the period associated with the sinusoidal function (T) is:

T = \frac{2\pi}{\omega}

By direct comparison, we get the following conclusions:

\Delta y = A (Amplitude) (Correct answer: 1)

\omega = B (Angular frequency) (Correct answer: 2)

x_{o} = C (Phase shift) (Correct answer: 3)

y_{o} = D (Vertical shift) (Correct answer: 4)

\frac{2\pi}{\omega} = \frac{2\pi}{B} (Period) (Correct answer: 5)
