Need help asap plz help dont have many points but ill give yu all i have if u help

Anna71 [15]

Hello!

We can go through the choices and see if they are true

Choice 1
A function has one output for every input

This is not a function because it has -1 as an output for both 4 and -1

This is the answer
------------------------------------------------------------------------------------------------------
Choice 2
The inputs are the x's

We see that the inputs are -1, 0, 3, and 4

This is true
------------------------------------------------------------------------------------------------------
Choice 3
The outputs are the y's

We see the outputs are -2, -1, and 1

This is true
------------------------------------------------------------------------------------------------------
Choice 4
We can follow the lines and see the relations are

(-1, 1), (0, -2), (3, 1), (4, -1)

This is also true
------------------------------------------------------------------------------------------------------
The only one that was false was the first choice so that is the answer

The answer is A) The diagram represents a function

A sound wave travels at 330m/s and has a wavelength of 2 m. calculate its frequency and period.

RoseWind [281]

Answer:

frequency= 165Hz

period= $\frac{1}{165}$

Step-by-step explanation:

1. To calculate the frequency using the formula:

f = v/λ

where,

f=frequency (what the question asked)

v=speed of wave (given in the question=330m/s)

λ=wavelength (given in the question=2m)

SO,

$f=\frac{330}{2}$

= 165Hz

2. To calculate the period use the formula:

since $f=\frac{1}{T}$

therefore, $T=\frac{1}{f}$

where,

f= frequency (what we solved above=165Hz)

T= period (what the question asked)

SO,

$T=\frac{1}{165}$

A line passes through the point (2, 10) and has a y-intercept of 4. What is the equation of the line?

KatRina [158]

Answer:

$y=3x+4$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is equal to 0)

1) Determine the slope (m)

$m=\frac{y_2-y_1}{x_2-x_1}$ where two points that the line passes through are $(x_1,y_1)$ and $(x_2,y_2)$

We're given the point (2,10) and the y-intercept of 4. Recall that the y-intercept occurs when x is equal to 0. This means that the y-intercept occurs at (0,4), giving us our second point.

Plug these points into the equation

$=\frac{10-4}{2-0}\\=\frac{6}{2}\\=3$

Therefore, the slope of the line is 3. Plug this into $y=mx+b$

$y=3x+b$

2) Determine the y-intercept (b)

The y-intercept is given; it is 4. Plug this back into $y=3x+b$

$y=3x+4$

I hope this helps!
