3. What line forms when a plane and a cylinder intersect?

Mathematics

The answer to this depends on the angle at which they intersect. If it intersects<span> the cylinder perpendicular to the axis then a circle is formed. </span><span>If the plane intersects the cylinder at an angle, it will form an ellipse. This will be true until the plan is parallel with the axis of the cylinder. At that point, the surface will become a rectangle.</span>

Identify the parent function that can be used to graph the function (x) = - 3x + 2
Sever21 [200]

Answer:

c

Step-by-step explanation:

the function (x) = -3x+2  can be obtained by :

* stretching the function (x)=x in the y-axis by 3 units gives 3x

* then reflecting about x-axis  gives -3x

* finally shifting it up by 2 units gives -3x+2

so the parent function is f(x) = x

If they are right triangles
Ahat [919]
You can use Pythagreos theorem to determine it!
Pythagreos theorem is a^2 + b^2 = c^2
1) 4^2 + 4^2 = 6^2
   16    +  16  = 36
         32       = 36 (So this is not a right-angled triangle )
2) 16^2 + 12^2 = 20^2
      256 + 144  = 400
       400          = 400 (Sp this is a right-ngled triangle)

Pls help I’ll brainlest ASAP and add extra points I’m failing
Step2247 [10]

Step-by-step explanation:

you drew already the right things, you have everything.

so, what is the problem ?

the most common form of line equation is

y = ax + b

a is the slope of the line. it is expressed as the ratio

y coordinate change / x coordinate change

when going from one point to the other.

b is the y-intercept (the y value when x = 0).

once we have the slope, we get b by using the coordinates of one of the given points as x and y in the equation and solve for b.

so, for the 2 marked points you showed correctly the differences :

x changes by +8 (from -4 to 4).

y changes by -2 (from 3 to 1).

so the slope is -2/+8 = -1/4

the y-intercept we also see directly in the chart : +2.
