Imagina that the cook is using a potato-chopping machine instead of a knife, allowing him to chop a maximum of 120 potatoes inst
FrozenT [24]

The number of hamburgers he could cook is 14 if he chopped 100 potatoes with the machine option (B) is correct.

<h3>What is the graph of the best estimate?</h3>

A mathematical notion called the graph of the best estimate connects points spread throughout a graph.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have shown a graph in the picture that shows the number of hamburgers cooked versus the number of potatoes chopped.

As we can see in the graph,

Number of potatoes chopped = 80

number of hamburgers cooked = 30

Number of potatoes chopped = 90

number of hamburgers cooked = 20

Number of potatoes chopped = 95

number of hamburgers cooked = 10

Number of potatoes chopped = 100

number of hamburgers cooked = 14 (best estimate)

Thus, the number of hamburgers he could cook is 14 if he chopped 100 potatoes with the machine option (B) is correct.

14] two drivers, starting at the same place, begin driving in opposite directions at the same time. one heads east at 65 kilomet
Juliette [100K]
They are driving in opposite directions, so the velocities need to be added together.
65+85=150
375/150=2.5 hours, or 150 mins

If Lylah completes the square for f(x)=x^2-12x+7 in order to find the minimum, she must write f(x) in the general form f(x)=(x-a
Ber [7]
<span>f(x) = x^2 - 12x + 7

First, separate the first two terms from the constant

f(x) = (x^2 - 12x) + 7

Next, half the coefficient of second term in the parenthesis (12x) and square the result. Make sure to subtract outside the parenthesis what you added inside so that the equation stays equal.

f(x) = (x^2 - 12x + 36) + 7 - 36
f(x) = </span><span>(x^2 - 12x + 36) - 29

Now, just factor the trinomial inside the parenthesis, lemme know in a comment if you don't know how to do this and I'll explain.

f(x) = (x(x - 6) -6(x - 6)) - 29
f(x) = (x - 6)^2 - 29

The polynomial is now in vertex form, and the value of a, as you can see, is 6.
