Concept: Modeling expressions
- We are given the equation
- [tex]200 - 16 {t}^{2} [/tex]
- We want to find the time after 0.75 seconds given that t is represented in seconds.
- Hence we do
- [tex]200 - 16(0.75)^{2} [/tex]
- Hence we get the answer to 191 feet
The height of the object that falls after 0.75 seconds given that t is represented in seconds is 191 feet.
What is a quadratic equation?
A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
The expression 200 - 16t^2 models the height in feet of an object that falls from the initial height of 200 feet t seconds after being dropped.
We need to find the time after 0.75 seconds given that t is represented in seconds.
The expression is given
[tex]200 - 16t^2[/tex]
time t = 0.75
Substitute the value of t in the given expression
= 200 - 16(0.75)^2
= 200 - 9
= 191
Hence we get the answer to 191 feet.
