b) Height
Insert the value of t into one of the equations.

The diagram below shows that the trajectories of the balls intersect after 0.4 s at a height of 4.016 m.
Answer:
65%
Step-by-step explanation:
this is because there is need for us to multiply 65% by $58.00
Your function is: 
Domain: $(-\infty, +\infty)-\{ 0 \}$ or $R-\{ 0 \}$
Range: $[-\frac{3}{2}, -\frac{1}{2}]$
Midline: $y=-1$
After identifying primary segmentation variables, an effective segment should be the next step.
<h3>What is variable?</h3>
A variable can change, in contrast to a numerical number, which has to remain constant, hence the name. As implied by the name, a variable is something that changes. Its true value can therefore change. A variable in mathematics is a sign and placeholder for a variable quantity or other mathematical object. As with any idea, variables are easier to use the more you use them. A variable is so named because it is capable of changing, as opposed to a numerical value, which must remain constant. Maths classes tend to get harder because they will expect you to use more variables in different ways.
