Tranh dives off a 9 m platform. He reaches a maximum height of 9.2 m after 0.26 s. How long does it take him to reach the water
1 answer:
He will reach the ground after 2.023 seconds.
To start, write a quadratic equation in vertex form with the given information about the vertex.
All that we need to solve for is a. Plug in the point (0, 9) and you will be able to solve for a and write the complete equation.
Now, just use the quadratic formula and you will get 2.023 seconds for when he hits the ground.

Answer:
Distance: 435.9 ft
Step-by-step explanation:
This is a right triangle shown in the picture.
To solve for , we can use trigonometry.
The 35° angle's opposite side is 250 ft and the hypotenuse of the triangle is (what we are seeking to find).
The ratio that relates opposite and hypotenuse is sine.
<em>We know that,</em>
<em>Thus we can write:</em>
<em>Cross multiplying and solving for gives us:</em>
Second answer choice is right: 435.9 ft
