Terri walked in her own 93rd percentile, while April swam in her own 99th percentile. April is off to a slightly better start.
Answer:
y = x^2 - 4x - 6.
Step-by-step explanation:
The roots are 2 + √10 and 2 - √10, so in factor form we have:
(x - (2 + √10))(x - (2 - √10))
= ( x - 2 - √10)(x - 2 + √10)
= x^2 - 2x + √10x - 2x + 4 - 2√10 - √10x + 2√10 - √100
= x^2 -4x + 4 - 10
= x^2 - 4x - 6.
Answer: 3 and 13 the solution to the equation is 39
Step-by-step explanation:
If x is 0 then I think it would be the 3 to the second power and that is 9. Because 0 + 9 = 9. Correct me if I’m wrong!
Answer:
To solve this problem, we can use a system of equations.
We know the quadratic expression has the form
Using points (1,12) and (4,0), we can form the following system to find a and b.
We need to divide the second equation by -4 and sum both equations
Then, we use this value to find the other variable
<h3>Therefore, the quadratic function that models the situation is</h3>
or 
According to this expression, after 2 seconds, the height is 16 feet.
