Generally the equation for Stroke in a slider-crank Mechanism x is mathematically given by



Answer:
The scale factor is 
<u>We can say that both circles are similar.</u>
Step-by-step explanation:
If we move the little circle to the center of the bigger circle, so the <u>translate vector will be (3,5).</u>
Now we realize that the bigger circle is just a dilation of the smaller circle, the<u> scale factor is:</u>



Therefore, <u>we can say that both circles are similiar.</u>

Answer:
The first pair of figures would be a translation.
Step-by-step explanation:
A translation is a transformation that involves the shift or slide of a figure in the coordinate plane. This movement will only be either horizontal, vertical or a combination of both. The second and third set of figures given include not only a shift, but a reflection and rotation as well. The only set of figures that has been moved horizontally and/or vertically is the first set.
Answer: -3
Step-by-step explanation:
-3x+ 7x+ 35= 5x + 38
You solve the distributive property on the left side and set it equal to the right
4x+35= 5x+38
-4x -4x
35= x+38
-38 -38
X=-3
