Elapsed time t, in seconds Distance d, in centimeters (cm), a ball rolls in t seconds (s) Inclined Plane 1 Inclined Plane 2 0 0 0.0 1 5 6.5 2 20 26.0 3 45 58.5 4 80 104.0 5 125 162.5 Determine the distance a ball rolls, on inclined plane 1, during each of the following time intervals. Hint: To determine the distance a ball rolls in the interval t = 1 to t = 2 seconds, find the distance it rolls in two seconds and from this distance subtract the distance it rolls in 1 second. (a) 1st second: t = 0 to t = 1 second cm (b) 2nd second: t = 1 to t = 2 seconds cm (c) 3rd second: t = 2 to t = 3 seconds cm (d) 4th second: t = 3 to t = 4 seconds cm (e) 5th second: t = 4 to t = 5 seconds cm.

hi! this is just your daily reminder that you can do everything you put yourself to do no cap!!! :) ps. your supperrr smart =D

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
