Can someone help me with all this? Lol idk any of this and E-learning sucks I need to show my work as well

1a) 230 feet

1b) 3.75s

1c) t=7.54s

2) t=2s

3) t=2.32s

Step-by-step explanation:

The equation that models Brett's last home run is  

We need to complete the square to obtain the function in the vertex form:

1a) The vertex is (3.75,230).The maximum value is the y-coordinate of the vertex, which is 230 feet.

1b)  The time it takes to reach the maximum  value is the x-coordinate of the vertex. It reach the maximum heigth after t=3.75 seconds

1c) To find the time the ball hit the ground, we equate the h(t)=0 and solve for t.

The time is positive, so the ball hit the ground after 7.54 seconds.

Question 2)

The function that models the amusement ride is

We want to find the time it takes for the riders to reach the maximum height.

This time is given by:

Comparing   to we have a=-16, b=64, c=60.

We substitute to obtain:

Hence it took 2 seconds to rech the maximum height.

Question 3)

The equation that models the height f the catridge is

To find the  time that the catridge will land, we equate the function to zero and solve for t.

This is a quadratic equation with =-16, b=35, an c=5

The solution is given by:

We substitute the values to get:

This gives:

This simplifies to:

The time it takes to land must be positive thefore t=2.32 seconds

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

never fear papaguy is here
