When the graph of a quadratic function crosses the x-axis twice, the x-coordinate of the vertex lies ______ the two x-intercepts
Leno4ka [110]

Answer:

  "halfway between"

Step-by-step explanation:

The zero crossings are symmetrical about the line of symmetry, which is a vertical line through the vertex. The x-coordinate of the vertex s the average of the two x-intercepts, so lies between them--exactly halfway between them.

Whats the largest fraction 5/12 and 3/8​
maks197457 [2]

Answer:

5/12 > 3/8

Step-by-step explanation:

to see which is bigger, find the LCD of both fractions and whichever has the biggest numerator is the larger fraction.

the LCD of 5/12 and 3/8 is 24.

to get a denominator of 24 for 5/12 we would multiply the fraction by 2, which gives us 10/24

to get a denominator of 24 for 3/8 we would multiply the fraction by 3, which gives us 9/24.

10/24 > 9/24

looking back at the original fractions, 5/12 is the largest fraction

The number of traffic violations in a city increased from 12 to 16 in a month. What is the percent of increase in the number of
Tems11 [23]

Answer:

33%

Step-by-step explanation:

Percentage increase = \frac{increase}{initial value} x 100%

Number of traffic violations increased from 12 to 16.

Initial value = 12

Final value = 16

increase = Final value - Initial value

              = 16 - 12

              = 4

Percentage increase = \frac{increase}{initial value} x 100%

                                    = \frac{4}{12} x 100%

                                    = \frac{1}{3} x 100%

                                    = \frac{100}{3}%

                                    = 33.3333%

The percentage increase in the number of traffic violations for the month is 33%.
