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.
Answer:
A.) nine more girls read 6 or more than boys who read 6 or more books
Step-by-step explanation:
Let's examine the statements ...
a) 24 is 9 more than 15 . . . TRUE
b) 41 is 6 more than 36 . . . false
c) 32 is twice as many as 15 . . . false
d) 24 is twice as many as 48 . . . false
Answer:
5/8
Step-by-step explanation:
You need to convert to a simplified fraction by placing the numbers to the right of the decimal over 1000. Then reduce the fraction.
56 + 90 = 146 kilometers
4 + 2 = 6 hours
rate = 146 km / 6 hour
= 24.333 km / hour
Divide number of pounds eaten by the portion of the bag eaten.
= 4 1/2 pounds ÷ 3/4
= 4.5 ÷ 0.75
= 6 pound bag
CHECK:
multiply total pounds of bag by portion eaten
= 6 pound bag * 3/4
= 4 1/2 pounds eaten
ANSWER: The bag was 6 pounds of dog food.
Hope this helps! :)
