A football is punted from a height of 3.5 feet about the ground with an initial velocity of 45 feet per second. This situation can be represented by the function −16t2 + 45t + 3.5 , where t is the number of seconds elapsed since the football was kicked. If the football is caught at a height of 5.5ft on the ball’s descent, when was the football in the air at that height?

step-by-step explanation:

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
