Multiply 5 by 5 to get 25
25ab
Answer:


Step-by-step explanation:
<u>Factored form of a quadratic function</u>

where:
- p and q are the x-intercepts
- a is some constant
Given x-intercepts:
Therefore:


To find a, substitute the given vertex (2, -8) into the equation and solve for a:



Therefore, the function's equation in factored form is:

<u>Vertex form of a quadratic equation</u>
<u />
where:
- (h, k) is the vertex
- a is some constant
Given:
Therefore:

To find the constant a, substitute one of the x-intercepts into the equation and solve for a:



Therefore, the function's equation in vertex form is:

The total sum of students given four quarters = The student who spent the money on gum plus the students that kept the money.

The total sum of students given four quarters is 51 students.
The student who spent the money on gum is 34 students.
The probability of the students that spent the money, given that the students were given four quarters,

The probability is,

The probability is 0.667.
About 3, because there are 5280 feet in a mile, so 2 miles would be 10560, and 3 would be 15840, and that is the closest you will get, because the 4th miles would be 21120.
