It’s the quadratic formula because it’s give directly the zeros of a function
Answer:

Step-by-step explanation:
Quadratic function-
It is a function that can be represented by an equation of the form
, where
In a quadratic function, the greatest power of the variable is 2.
As in the first option the highest power is 3, so it is not a quadratic function.
Even though the power of x is 2 in the third option, but as it is in the denominator, so the overall power of x becomes -2. Hence it is not a quadratic function.
As the coefficient of
is 0 in case of fourth option, so it is not a quadratic function.
Equation in option 2 satisfies all the conditions of quadratic function, hence it is the quadratic function.
50 divided by 40 equals 1.25! So the car is going 1.25 mph

Step-by-step explanation:
<span>You are given
John Davis’ rate which is $9.75 an hour. It is said that he works for four
hours on Monday, six hours on Tuesday, five hours on Wednesday, five hours on
Thursday, and seven hours on Friday. You are asked to find the gross pay of John
Davis. All you need to do is to multiply the rate to the hour of work.</span>
<span>
Monday: $9.75(4h)
= $39</span>
Tuesday:
$9.75(6h) = $58.5
Wednesday:
$9.75(5h) = $48.75
Thursday:
$9.75(5h) = $48.75
Friday:
$9.75(7h) = $68.25
<span>
To get the
gross pay, add everything and you will get $263.25. The answer is letter D.</span>
