Step-by-step explanation:
1)
= 50 + (-9*8) *1
= 50 - 9.8
= 40.2 m/s
2) The acceleration of the ball at its maximum height equals to the force of gravity. -9.8 m/s²
3) The velocity at its top of the path:When the ball is thrown straight up, its velocity keeps on decreasing due the pull of gravity which pulls it towards the ground. So, the velocity at the top of its path is zero.

Step-by-step explanation:
I'm assuming you've already learnt how to draw an equation in slope intercept form. The line of an inequality is drawn the same way.
The difference is that for inequalities you will have to shade.
Basically, the inequality sign will tell you which are to shade.
Greater than will mean above the line and
Less than will be below the line.
Also, if the sign is a "or equal to" sign, then the line will be solid, if not, it's dotted.
1) Since these triangles are congruent, then we can write out the following for congruent triangles have congruent sides:
2) Still based on that principle, we can plug v=2 into any of those formulas to get the measure of QS and TV. So let's pick the simpler one:
As we can see these segments are congruent.
