Answer:

option 3

Step-by-step explanation:

Standard \ quadratic \ equation : ax^2 + bx +c

Larger the value of  '' a '' makes the parabola narrow.

A positive value of '' a '' which is close to 0 makes the parabola wide.

<em><u>To find the widest graph , find the smallest </u></em><em><u>a</u></em><em><u>. (or </u></em><em><u>a</u></em><em><u> closest to zero)</u></em>

option 1

     a_1 = \frac{1}{3}

option 2

     a_2 = - \frac{4}{5}

option 3

     a_3 = 0.3 = \frac{3}{10}

option 4

     a_4 = -4

Positive and negative value of ' a ' decides the direction the parabola opens.

But we have to find the widest parabola irrespective of the direction.

So we will find the smallest  ' a '

                                a_1 = 0.33\\a_2 = 0.80\\a_3 = 0.30\\a_4 = 4

a_3 \ is \ the \  smallest \  number \  or\ \\ the \  number \  closest \  to\  zero.\\\  so \  option \ 3 \ makes\  the\  widest \ parabola.

By what percent change if the numerator is decreased by 10% and the denominator is decreased by 70%
hjlf

Answer:

It increases x3.

Step-by-step explanation:

Let's say the fraction to begin with was 100/100. Ignore the fact that it isn't fully reduced and it is an improper fraction.

10% of 100 is 10, so the numerator is now 90 (decrease=get smaller; 100-10=90).

70% of 100 is 70, so the denominator is now 30 (decrease=get smaller; 100-70=30).

Our fraction is now 90/30 which, when fully reduced, equals 3.00. Since 100/100 equals 1.00, it has increased by 2.00 (3x bigger).
