I think that you can use demos it is a calculator just put the point and you get the answer
Answer:

Step-by-step explanation:
Given



Required
Coordinates of B
This question will be answered using line ratio formula;

In this case:



Solving for 
becomes



Comparing the right hand side to the left;
-- (1)
-- (2)
Solving (1)


Solving (2)


Hence;

The maximum height of the projectile is the maximum point that can be gotten from the projectile equation
The projectile reaches the maximum height after 5 seconds
The function is given as:

Differentiate the function with respect to t

Set to 0

So, we have:

Collect like terms


Solve for t


Hence, the projectile reaches the maximum after 5 seconds

let the number of adult tickets be x and the number of children tickets be y
3x + y = 164...equ(1)
2x + 3y = 174....equ(2)
multiplying equation 1 by 3
9x + 3y = 492
subtracting equation 2 from 1
7x = 318
x = 45.43 dollars
substituting the value of x into the equation
3(45.428) + y = 164
y = 164 - 3(45.428)
∴y = 27.71 dollars
