When joey dives off a diving board, the equation of his pathway can be modeled by h=-16tsquared+15t+12. Find joeys maximum height and the time it will take for joey to reach the water

Given : When joey dives off a diving board, the equation of his pathway can be modeled by .

We use vertex formula to find the maximum height of quadratic polynomial . (i)

As compare the given polynomial to (i), we have

a=-16 and b= 15

Then , the maximum height =

Hence, the maximum height is 0.46875 m.

When Joey reaches the water then h= 0

i.e.

Hence, the time it will take for Joey to reach the water is 1.45 seconds.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
