A large explosion causes wood and metal debris to rise vertically into the air with an initial velocity of 80 feet per second. The function h(t) = 80t - 16t2
gives the height of the falling debris above the ground, in feet, t seconds after the explosion.
A) Use the given function to find the height of the debris 4 seconds after the explosion:
After 4 seconds, the height is
feet.
B) How many seconds after the explosion will the debris hit the ground?

seconds.

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

good luck on ur quiz test or homework. have a good day : )
