You plug 11 in where x is.
r(11) = (11 + 1)(11 - 3)
= (12)(8)
= 96
Answer: Option D
Step-by-step explanation:
Note that the projectile height as a function of time is given by the quadratic equation
To find the maximum height of the projectile we must find the maximum value of the quadratic function.
By definition the maximum value of a quadratic equation of the form
is located on the vertex of the parabola:
Where 
In this case the equation is:
Then
So:
Answer:
A

Answer:
11
Step-by-step explanation:
Let the number be x.
Then by the question,
2x+4 = 3x-7
x=11
Answer:
3
Step-by-step explanation:
The given shape is a right angled triangle.
Here,
Hypotenuse = 2√3
Another side = √3
Let the missing side length be " x ".
By Hypotenuse theorem,
x² + ( √3 )² = ( 2√3 )²
x² + 3 = 12
x² = 12 - 3
x² = 9
x² = 3²
x = 3
Therefore, the side length is 3.
