The graph of a function is a parabola that has a minimum at (-1,-2) and goes through the point (0,1).

Answer:

f(x) = 3 x^{2} + 6x +1

Step-by-step explanation:

Since they give us the coordinates of the minimum of the parabola (the parabola's vertex), we start by writing the function in vertex form:

f(x) = a (x-xvertex)^{2} + yvertex = a (x- -1)^2 + (-2) = a (x+1)^2 - 2

Now we use the fact that the point (0,1) is on the graph of the parabola, which means that when x=0, the value of the function (y) must be equal to 1.

We apply this to the expression we found above:

f(0) =  a (0+1)^2 -2 = 1

which gives us:  a (1) -2 =1  therefore, a = 3

Now we write the function using the value of the constant a we just found:

f(x) = 3 (x+1)^2 -2

and next we find the square of the binomial (x+1) to express the function in standard form:

f(x) = 3 (x^2 +2x+1) -2 = 3x^2 +6x +3 -2 = 3x^2 +6x +1

When x=1/2, what is the value of 8x-3 over x?
Taya2010 [7]

\frac{8( \frac{1}{2}) - 3 } { \frac{1}{2} }
\frac{(8 \times \frac{1}{2}) - 3 }{ \frac{1}{2} }  =  \frac{4 - 3}{ \frac{1}{2} }
Because half of 8 is 4

\frac{1}{ \frac{1}{2} }  =  \frac{1 \times 2}{1 \times 1} = 2
Divide 1 by 1/2 or .5... 1 becomes 1/1 and 1/2 is flipped to 2/1, then multiply

The quotient is 71 2/3 what is the divisor
Genrish500 [490]
The divisor is 3.
It is 3 because to make the whole number and the remainder a mixed number you take the whole number then for the numerator you write what is left over(remainder) and for the denominator you will write the divisor. In this case the denominator is 3 so the divisor is 3.

Answer: 35 additional teachers are needed

-------------------------------------------------
-------------------------------------------------

Explanation:

We have 2470 students and the ratio of students to teachers is 26:1. This means that for every teacher, there are 26 students. Put another way, we can set up this ratio

2470/x = 26/1

where x is the number of teachers. Cross multiply and solve for x

2470/x = 26/1
2470*1 = 26*x
2470 = 26x
26x = 2470
26x/26 = 2470/26
x = 95

So we have 95 teachers currently

-------------

Let y be the new number of teachers needed to bring the ratio down to 19:1

Using a similar idea as done above, we would have this ratio

2470/y = 19/1

Let's solve for y
2470/y = 19/1
2470*1 = 19*y
2470 = 19y
19y = 2470
19y/19 = 2470/19
y = 130

So we'll need 130 teachers to have the ratio be 19:1

The difference of the values is y - x = 130 - 95 = 35, which is the final answer. This is the additional amount of teachers needed.
