The missing value is 3 because roots of the function f(x) = x2 – 2x – 3 are -1 and 3
Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
We have a function:
f(x) = x² – 2x – 3
Equate the function to zero;
f(x) = 0
x² – 2x – 3 = 0
a = 1, b = -2, c = -3
After simplification:
x = 3 or x = -1
Thus, the missing value is 3 because roots of the function f(x) = x2 – 2x – 3 are -1 and 3

A. 5/12
B. 6/12
C. 5/8
D. 6/8
Answer:
5/12
Step-by-step explanation:
of means multiplication. so multiply 5x2 / 6x2 which is 5/12
Answer:
A. 5/12
Step-by-step explanation:
the "of" in the answer is asking you to multiply.
what you want to do is multiply the numerators and denominators.
5 x 1 = 5
6 x 2= 12
giving you 5/12!
hope this helps <3

Answer:
The horizontal distance from the starting point when rocket lands is:
168.83 meters.
Step-by-step explanation:
We are given a function that models the height of the rocket when it is 'x' meters away from the starting point.
The function is:
Now we are asked to find the horizontal distance from the starting point when the rocket will land.
i.e. we are asked to find 'x' ; when y=0
i.e.
Let y=0
on solving the quadratic equation we obtain:
As the distance can't be negative.
Hence, the viable solution is:
x=168.83
