Write a quadratic function in standard form with a leading coefficient of 1 for the given set of zeros. 7 and 4
Viefleur [7K]

We are given : Zeros x=7 and x=4 and leading coefficent 1.

In order to find the quadratic function in standard form, we need to find the factors of quadratic function first and the multiply by given leading coefficent.

For the given zeros x=7 and x=4, we get the factors (x-7) and (x-4).

So, we need to multiply (x-7) and (x-4) by foil method.

We get

(x-7)(x-4) = x*x + x* -4 -7*x -7*-4

x^2 -4x -7x +28.

Combining like terms, we get

-4x-7x = -11x

x^2 -4x -7x +28 = x^2 -11x +28.

Now, we need to multiply x^2 -11x +28 quadratic by leading coefficent 1.

We get

1(x^2 -11x +28) = x^2 -11x +28.

Therefore, the required quadratic function in standard form is x^2 -11x +28.

The time on the clock is 5:35 set the clock below to show what time it will be in a 11 hours and 38 minutes. Thank you
lora16 [44]

A clock is 12 hours.

11 hours and 38 minutes is 22 minutes short of being a full 12 hours.

In 12 hours the time would be 5:35 again, so now subtract 22 minutes from the time:

5:35 - 22 minutes = 5:13

In 11 hours and 38 minutes, the time will be 5:13
