Which rule describes the translation below ? In the picture
rewona [7]

The translation rule which describes the given translation is \fbox{\begin\\\math{(x,y)}\rightarrow(x+5,y-3)\\\end{minispace}}.

Further explanation:

Translation is defined as the shifting of the curve in which each point on the curve is shifted in such a way that the shape and size of the curve remains unchanged but the position of each point is changed by a fixed distance.

In the given figure there are two right angle triangle as S'T'U' and STU.

The coordinates of the right angle triangle S'T'U' are (-4,2),(-4,-2) and (-1,-2) and the coordinates of the right angle triangle STU are (1,5),(1,1) and (4,1).  

Consider that the triangle STU is obtained after the translation of each point on the triangle S'T'U'.  

The coordinate of the point S' in triangle S'T'U' is (-4,2).  

Step 1:  

Use the translation (x,y)\rightarrow(x-5,y-3) for the point S'.  

\fbox{\begin\\\(-4,2)\rightarrow(-4-5,2-3)=(-9,-1)\\\end{minispace}}

As per the translation (x,y)\rightarrow(x-5,y-3) the coordinate of the point S is (-9,-1), but in the given figure the coordinate of the point S is (1,5).  

So, the translation (x,y)\rightarrow(x-5,y-3) is incorrect.  

Step 2:  

Use the translation (x,y)\rightarrow(x-3,y-5) for the point S'.  

\fbox{\begin\\\(-4,2)\rightarrow(-4-3,2-5)=(-7,-3)\\\end{minispace}}

As per the translation (x,y)\rightarrow(x-3,y-5) the coordinate of the point S is (-7,-3), but in the given figure the coordinate of the point S is (1,5).  

So, the translation (x,y)\rightarrow(x-3,y-5) is incorrect.  

Step 3:  

Use the translation (x,y)\rightarrow(x+5,y+3) for the point S'.  

\fbox{\begin\\\(-4,2)\rightarrow(-4+5,2+3)=(1,5)\\\end{minispace}}

As per the translation (x,y)\rightarrow(x+5,y+3) the coordinate of the point S is (1,5) which is correct as the coordinate for the point S given in the figure is (1,5).  

Step 4:  

Use the translation (x,y)\rightarrow(x+5,y+3) for the point T'.  

\fbox{\begin\\\(-4,-2)\rightarrow(-4+5,-2+3)=(1,1)\\\end{minispace}}  

As per the translation (x,y)\rightarrow(x+5,y+3) the coordinate of the point T is (1,1) which is correct as the coordinate for the point T given in the figure is (1,1).  

Step 5:  

Use the translation (x,y)\rightarrow(x+5,y+3) for the point U’.  

\fbox{\begin\\\ (-1,-2)\rightarrow(-1+5,-2+3)=(4,1)\\\end{minispace}}

As per the translation (x,y)\rightarrow(x+5,y+3) the coordinate of the point T is (4,1) which is correct as the coordinate for the point U given in the figure is (4,1).  

As per the above calculation it is concluded that the translation (x,y)\rightarrow(x+5,y+3) is correct for the shifting of each point on the triangle S'T'U' to each point on the triangle STU.

The translation of each point on the triangle S'T'U' is shown in the image attached below.

Therefore, the correct translation rule for the shifting of the triangle S'T'U' to the triangle STU is \fbox{\begin\\\math{(x,y)}\rightarrow(x+5,y-3)\\\end{minispace}}

A surfer is riding a 7 foot wave. The angle of depression from the surfer to the shoreline is 10 degrees. What is the distance f
denis23 [38]

Step-by-step explanation:

The distance from the surfer to the shoreline will be found as follows:

tan θ= opposite/adjacent

θ=10°

opposite=7ft

adjacent= x ft

substituting the values in our formula and solving for x we get

tan 10=7/x

hence

x=7/tan10

x=39.69897~ 39.7 ft

The surfer is 39.7 ft from the shoreline.

HELP! SHOW ALL WORK AND EXPLAIN. :P
weeeeeb [17]
♥It says that he adds 12$ each week, and by the end of 3 weeks he had 60. Well if you do 12*3
And that =36.
But as you can see its not 60 so we have to find out how much money he had in there before.
He had 24$ in there before he started doing this.
You can find this by doing 36+x=60 and 36+24=60.
Now if you do 12*15
You get 180.
Now add the 24 dollars he already had in there.
180+24=204
He had 204$ at the end of wk.15
♥Hope this helps!♥

Equation of the existing water pipe's line

a) slope, m = rise / run = Δy / Δx = 3/2

b) y-intercept, b = 3

equation: y = mx + b = (3/2)x + 3

Equation of the new water pipe's line

slope, m = - 1 / (slope of the perpendicular line) = - 1 / (3/2) = - 2/3

point (0,2)

=> y - 2 = (-2/3) (x - 0) => y = (-2/3)x + 2 <---- equation of the new pipe

28)

two parallel lines have the same slope =>

slope, m = rise / run = Δy / Δx = [4 - 0] / [11 - 8] = 4 / 3

point (4,5) => y - 5 = (4/3) (x - 4)

=> y = (4/3)x - 16/3 + 5 = (4/3)x - 1/3

y = (4/3)x - 1/3  <--- equation of the new bike path
