Answer:
The quadratic function whose graph contains these points is 
Step-by-step explanation:
We know that a quadratic function is a function of the form 
. The first step is use the 3 points given to write 3 equations to find the values of the constants <em>a</em>,<em>b</em>, and <em>c</em>.
Substitute the points (0,-2), (-5,-17), and (3,-17) into the general form of a quadratic function.
We can solve these system of equations by substitution
- Substitute
- Isolate a for the first equation
- Substitute
into the second equation
The solutions to the system of equations are:
b=-2,a=-1,c=-2
So the quadratic function whose graph contains these points is
As you can corroborate with the graph of this function.
Answer:
b) 29π mm²
Step-by-step explanation:
Step-by-step explanation:
x2 - 4x - 12
Finding factors of 12 then
x2 - 6x + 2x - 12
x( x - 6) + 2 (x - 6)
So the factors are (x+2) (x-6)
Answer:
The given expression is equivalent to 3(2^(3/8))x.
Step-by-step explanation:
The given expression (3 root 8^1/4 x) can be written as:
3√(8^(1/4))x
we know that 2^3 = 8
= 3√(2^(3/4))x
We know that √x = (x)^(1/2)
= 3(2^((3/4)(1/2))x
Powers multiply with each other, 3*1/4*2 = 3/8
= 3(2^(3/8))x
It can't be simplified, because
