Answer: Look at explanation for answer...

Step-by-step explanation:

This could be turned into a simple proportion if you want to do it that way :)

1.) First, use the proportion bacteria over time.

2.) It should set up to look like this:  2,600        X

                                                           ---------- = ---------

                                                               7             15

3.) You then do your math (2,600 * 15) (39,000 / 7)

Answer: Your answer then comes out to be: (rounded) 5,571 bacteria

Write the standard form of the quadratic function whose graph is a parabola with the given vertex and that passes through the gi
maks197457 [2]

Answer:

The formula for this quadratic function is x*2 +6x+13

Step-by-step explanation:

If we have the vertex and one point of a parabola it is possible to find the quadratic function by the use of this

y= a (x-h)*2 + K

Quadratic function looks like this

y= ax*2 + bx + c

So let's find the a

y= a (x-h)*2 + K where

y is 13, x is 0, h is -3 and K is 4

13= a (0-(-3))*2 +4

13=9a +4

9=9a

9/9=a

1=a

The quadratic function will be

y= 1(x+3)*2 + 4

Let's get the classic form

(x+3)*2 = (x+3)(x+3)

(x*2+3x+3x+9)

x*2 +6x+13

f(0) = 13
