The y intercept does not change.

you did a good job in putting the 1 under-2. since slope represents rise over run. but think about which way the slope is going to go now. instead of 1 rise for 1 run, it is now -2 rise(which means it goes down instead of up) for 1 run. Let me know which answer you think is correct and I'll let you know if your right.

I hope I helped but I honestly have no idea if I did. Anyway sorry if I didn't. Good luck.

If you reflect any shape across the x-axis and then across the y-axis, do you get the same result that you would if you rotated

Anton [14]

Yes, it has the same result

look at the picture. the red triangle is the first image. the green one is the result of reflecting over x-axis. then if you reflect it over y-axis, it would be the purple triangle

if you had rotated the red triangle at first, it would have the same result

good luck

The Atlantic Salmon swim upstream at a steady rate of 2 miles every 3 minutes. Fill in the table to describe the relationship. R

Likurg_2 [28]

The distance traveled by the Salmon is proportional to the duration spent

swimming.

A table of the distance traveled by the Atlantic Salmon is presented as follows;

$\begin{tabular}{|c|c|c}\underline{Time in minutes}&\underline{Miles Traveled at 2/3 miles per minute } \\1&2/3 \\2&4/3\\3&2\\4&8/3\\5&10/3\\6&4\end{array}$

Reasons:

The given parameter are;

The steady rate at which Atlantic Salmon swims = 2 miles in 3 minutes

Distance the Salmon swims, d ∝ Time taken, t

Therefore;

d = s·t

Where;

s = The constant of proportionality = The speed

Which gives;

$\displaystyle s = \mathbf{\frac{Distance, \, d}{Time, \, t}}$

The speed with which the Atlantic Salmon swims per minute is therefore;

$\displaystyle The \ speed = \mathbf{\frac{2 \ miles}{3 \ minutes}} = \frac{2}{3} \ miles /minute$

The distance travelled, <em>d</em>, is given as follows;

$\displaystyle d = \mathbf{\frac{2}{3} \times t}$

A table showing the distance travelled by the fish with time is presented as follows;

$\begin{tabular}{|c|c|c|}\underline{Time, t, in minutes}&\underline{t \times d}&\underline{Miles Traveled, d, at 2/3 miles per minute } \\1&1 \times 2/3 = 2/3&2/3 \\2&2 \times 2/3 = 4/3&4/3\\3&3 \times 2/3 = 2&2\\4&4 \times 2/3 = 8/3&8/3\\5&5 \times 2/3 = 10/3&10/3\\6&6 \times 2/3 = 4&4\end{array}$

One shape is approaching a poor from the east traveling west at 15 mph and its presently 3 miles east east of the port I second

valentinak56 [21]

Answer:

DL/dt = 17 mph

Step-by-step explanation:

The ships and the port shape a right triangle

Ship going west ( x-direction) is traveling at 15 mph

Ship going north (y-direction) is traveling at 10 mph

The distance L between ships is:

L² = x² + y²

Tacking derivatives on both sides of the equation with respect to time

we get

2*L*DL/dt = 2*x*Dx/dt + 2*y*Dy/dt (1)

In that equation we know:

Dx/dt = 15 mph

Dy/dt = 10 mph

At the moment ship traveling from the east is at 3 miles from the port

then x = 3 m and the other ship is at 4 miles north

then by Pythagoras theorem

L = √ 3² + 4² L = 5

By substitution in equation 1

2*5*DL/dt = 2*3*15 + 2*4*10

10* DL/dt = 90 + 80

DL/dt = 170 / 10

DL/dt = 17 mph
