Answer:
radius ≈ 15.5
Step-by-step explanation:
the radius is RS
the angle between a tangent and the radius at the point of contact is 90°
then Δ RST is a right triangle
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , then
RS² + ST² = RT² ( substitute values )
RS² + 7² = 17²
RS² + 49 = 289 ( subtract 49 from both sides )
RS² = 240 ( take square root of both sides )
RS =
≈ 15.5 ( to 1 dec. place )
Answer:
Since zero is on the origin (0,0) a 90 degree rotation will intercept the origin no matter what so, it can't be parallel.
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
So we have the equation:

This is in the format point-slope form, where:

Here, m is the slope.
In our original equation, 2 replaces m.
Therefore, our slope is 2.
