Lin and Clare were standing in the woods near a stream, and each threw a stone up in the air at the same time so that it would land in the water. The graph represents the height of a stone t seconds after it was tossed up by Lin. The function f given by f(t)=−16(t+12)(t−1) represents the height of a stone t seconds after it was thrown by Clare. In both functions, height is measured in feet.

a. Whose stone hit the water first?
When did that happened?
second after the stone was tossed

b. Clare’s stone reached its maximum height 14 second after it was tossed. Did Clare’s stone reach a higher maximum than Lin’s stone?

c. What was the maximum height of Clare's stone?
meters

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

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

i believe that the slope of the line is -5
