Pizzas are circles. Area of circles is (pi)r^2.

Then find the cost per in.^2

Smallest cost per in.^2 is better buy.

The formula for area is A = pi × radius^2. In this case, you are given diameter. Cut the diameter in half yo find the radius and plug the radius into the equation (Ex: for the first pizza the setup would be A = pi × 4^2.)

If i kick a soccer ball 10 feet and i comes back, how did this happen

Harman [31]

It likely hit a barrier like a wall for example and the force of the ball hitting the wall caused it to be pushed away. Another possibility is that the ball was kicked up some sort of slop and when it was at the ten feet it slowed down and then rolled back down. I hope this helps.

Let R(x), C(x), and P(x) be, respectively, the revenue, cost, and profit, in dollars, from the production and sale of x it

sp2606 [1]

Answer:

$P(x) = -0.004x^2 - 3.7x - 50$

Step-by-step explanation:

We have to find profit $P(x)$ .

This can be easily found using a formula for Profit given the Revenue and Cost.

$Profit = Revenue - Cost$

$P(x) = R(x) - C(x)$

Given that:

$R(x) = 6x$

$C(x) = 0.004x^2 + 2.3x + 50$

to find P(x) we can simply subtract R(x) by C(x).

$P(x) = R(x) - C(x)$

$P(x) = (6x) - (0.004x^2 + 2.3x + 50)$

$P(x) = 6x - 0.004x^2 - 2.3x - 50$

and finally, after simplify this equation subtracting 6x by 2.3x.

this is the equation for the profit $P(x)$

$P(x) = -0.004x^2 - 3.7x - 50$

The figure shows square KLMN. Which of the following conditions satisfy the criteria for squares?

BartSMP [9]

Answer:

First option: Square $KLMN$ with diagonals $LN$ and $KM$ .

Fifth option: Segment $LM$ is parallel to segment $KN$ .

Step-by-step explanation:

We know that a square is quadriteral whose sides are equal.

By definition, a square has the following properties:

1) Its four sides are congruent.

2) The diagonals are congruent.

3) The angles formed by the intersection of the diagonals measure 90 degrees.

4) The opposite sides are parallel.

5) Each internal angle measures 90 degrees.

Notice in the figure that:

The diagonals of the square $KLMN$ are: $LN$ and $KM$ .

$LM$ and $KN$ are opposite sides, therefore, they are parallel.
