The function, f(x) = –2x2 + x + 5, is in standard form. The quadratic equation is 0 = –2x2 + x + 5, where a = –2, b = 1, and c =
avanturin [10]
Given:

The function, f(x) = -2x^2 + x + 5

Quadratic equation: 0 = -2x^2 + x +5
where a = -2
            b = 1
            c = 5

The discriminate b^2 - 4ac = 41

To solve for the zeros of the quadratic function, use this formula:

x = ( -b +-√ (b^2 - 4ac) ) / 2a

x = ( 1 + √41 ) / 4  or 1.85
x = ( 1 - √41 ) / 4  or -1.35

Therefore, the zeros of the quadratic equation are 1.85 and -1.35.

In 7th grade there are 58 students with red-hair and 609 students with another color hair. The numbers of red-haired students in
mr_godi [17]

In 7th grade:

red-hair students =58

another color hair students =609

In 8th grade:

red-hair students =60

Let's assume

another color hair students =x

now, we are given

The numbers of red-haired students in 8th grade are proportional to the numbers in 7th

so,

\frac{60}{58} =\frac{x}{609}

now, we can solve for x

we get

x=609*\frac{60}{58}

we get

x=630

so, students have another color hair in 8th grade is 630.........Answer
