A line has the points (3,7) (4,9) (5,11) (6,13). If the slope is divided by 2, what is the new slope?

lorasvet [3.4K]

Answer:

The new slope is 1

Step-by-step explanation:

The slope of any two points can be found by:

$slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Finding slope of (3,7) (4,9)

$slope=\frac{9-7}{4-3}\\slope=\frac{2}{1}\\slope=2$

Finding slope of (4,9) (5,11)

$slope=\frac{11-9}{5-4}\\slope=\frac{2}{1}\\slope=2$

So, the slope of the line is 2

Now if slope is divided by 2, new slope will be:

$slope = \frac{2}{2}\\slope=1$

So, The new slope is 1

Answer:

Graph (6, 5) and (-6, -3), and then use a ruler (optional), and draw a line between them, and a little after the points.

Step-by-step explanation:

y = 2/3x + 1

Substitute different numbers for x, and find y:

You don't really want to work with fractions, so try to find a number that when multiplied by 2/3, gives you a whole number

x = 6

y = 2/3(6) + 1

y = 12/3 + 1

y = 4 + 1

y = 5

Point: (6, 5)

x = -6

y = 2/3(-6) + 1

y = -12/3 + 1

y = -4 + 1

y = -3

Point: (-6, -3)

Graph these two points, and then use a ruler (optional), and draw a line between them, and a little after the points.

The speed of the star as compared to the speed of the star relative to earth is the frequency of light emitted by the source.

A star moving away from the observer (say on Earth) will have its emitted light red-shifted (move to lower frequency), i.e., the spectrum moving to left if we consider the intensity of light is plotted as a function of frequency with the frequency increasing from left to right.

A star moving towards the observer (say on Earth) will have its emitted light blue-shifted (move to higher frequency), i.e., the spectrum moving to the right if we consider the intensity of light is plotted as a function of frequency with the frequency increasing from left to right.

A star moving perpendicular to the observer (say on Earth) will have its emitted light will no change with respect to the spectrum of the stationary star.

These are due to the Doppler effect, the equation of frequency detected by the observer as

$f_o = f_s\sqrt{\frac{1-\beta }{1+\beta } }$ where $\beta = \frac{v}{c}$ , v the relative velocity of the moving source (the star here), f^s is the frequency of light emitted by the source.

Hence the answer is the speed of the star as compared to the speed of the star relative to earth is the frequency of light emitted by the source.

Paul [167]

Answer: 3/14

Step-by-step explanation:

They traveled 5/7 of the distance on Saturday and 1/2 of the remaining distance, 3/7 , on Sunday so...

(1/2)(3/7)= 3/14

Hope this helps :)
