Step-by-step explanation:
<u>Step 1: Define</u>
y = 2x + 1
x = 1
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: y = 2(1) + 1
- Multiply: y = 2 + 1
- Add: y = 3
Ok here's what I make of this: you're in calculus and you're working with functions and their first derivatives, which are the position function and the velocity function, respectively. You need to figure out what the functions are so you can solve the problem. But the acceleration due to gravity goes into the velocity function as -32t; in the position function, the antiderivative of velocity, it goes in as -16t^2. The position function is s(t) = -16t^2 + 48t + 400. When you solve that for t, what you get is the time the rock hits the ground. When you find that t value, sub it into the velocity equation to find the velocity at that time the rock hits the ground. Solving for t (using the quadratic equation) you get a t value of 6.720153. The velocity equation, the first derivative, is v(t) = -32t + 48. Subbing the t value of 6.720153 in you get that the velocity is -167.045. Negative is correct here as well because it was positive going up and now it's coming down.
