Does lower production cost increase profit?
Yes lower production cost increase profit.
Production costs are expenses, such as labor and materials that your company incurs within the course of producing the product that you simply offer to consumers. In common, the lower your generation cost, the higher your benefit, or the sum you've got remaining after you subtract your costs from your sales revenue. lower production costs generally lead to higher profits. When production costs are lower, companies can charge lower prices and still make a profit, or they can keep prices the same and earn higher profits. Lower production costs also reduce the amount of money spent on materials, labor, and other expenses, leaving more of the revenue as profit.

The transformation equivalent to the reflection across the line q = -1, followed by the reflection across the line p = 2, [tex]r_p \circ r_q[/tex] is a translation of 6 units to the right.
What is a reflection transformation?A reflection transformation is one in which the points of the image are mirrored across the line of reflection.
The coordinate of a point (x, y) following a reflection about the y-axis is the point (-x, y)
The line x = -1 is parallel to the y-axis, therefore, only the x-coordinate of the preimage point (x, y) will change following the reflection across the line, q, [tex]r_q[/tex], x = -1
The relative x-coordinate of a point (x, y) to the line x = -1 is x + 1
Therefore, the image of the point (x, y) following the reflection across the line x = -1 and relative to the line is the point (-(x + 1), y) = ((-x - 1), y)
Relative to the x-axis, the point ((-1 - x), y) is (-1 + (-1 - x), y) = (-2 - x, y)
The coordinate of a point (x, y) relative to the line x = 2 is (x - 2, y)
Therefore, the coordinate of the point ((-2 - x), y) relative to the line x = 2 is ((-2 - x) - 2, y) = ((-4 - x), y)
The image of the point ((-4 - x), y) following a reflection across the line x = 2, [tex]r_p[/tex], is (-(-4 - x), y) = ((4 + x), y)
Relative to the y-axis, the coordinate of the image point ((4 + x), y) is ((2 + (4 + x)), y)

A hollow pipe is submerged in a stream of water so that the length of the pipe is parallel to the velocity of the water. If the water speed doubles and the cross-sectional area of the pipe quadrupled, what happens to the volume flow rate of the water passing through it?.
The volume flow rate of the water passing through the pipe increases by a factor of 6.
Assuming that the initial cross sectional area of the pipe is A m² and the initial velocity of the water is V m/s, the water flow rate is:
= initial flow rate = area × velocity = AV m³/s
As the water speed doubles (2V m/s) and the pipe cross-sectional area triples (3A m²), the volume flow rate becomes:
Final flow rate = 2V × 3A = 6AV m³/s
As a result, the volume flow rate of the water moving through it multiplies by a ratio of six.
The basic equation for cases like these is
Q=AV,
where Q is the volume flow rate, A is the cross-sectional area occupied by the flowing material, and V is the average velocity of flow.
V is considered an average since not every component of a flowing fluid flows at the same rate. If you monitor the waters of a river moving slowly downstream at a consistent rate of gallons per second, you will see that the surface has slower currents here and faster currents there.

a) The amount of water in the tank will be 0 after 5 minutes.
b) As time increases, the amount of water decreases at a rate of -60 L/min.
At which time the water reaches 0 liters?Here we can see a graph of a linear function that relates the amount of water in an aquarium (vertical axis) with the time (horizontal axis).
The amount of water in the aquarium will reach the 0 liters mark when the line intercepts the x-axis.
We can see that happens for x = 5 minutes
b) We can see that as we move to the right (time flows to the right in that graph) the line goes downwards. This means that the amount of water on the tank decreases as the time increases.
We can see that in 5 minutes, the amount of water goes from 300 lites to 0 liters, so the rate at which the water comes out of the tank is:
R = 300L/5min = 60 liters per minute.
It should actually be written with a negative sign so we are 100% clear that it means that the water is coming out from the tank, so the rate is:
R = -60 L/min

Jessica bought two tickets of the same price. She then sold one of the tickets at a profit of 10% and the other
one at a loss of $18. It is given that the difference in the selling prices of these two tickets is $36.
(a) Find the cost of each ticket for Jessica.
(b) Did she make an overall profit or loss? Explain your answer
Please give explanation!!! Will give brainliest ty ty!!
Answer and Step-by-step explanation:
Let the cost of each ticket for Jessica be $x. If she sold one of the tickets at a profit of 10%, she got $x + 0.1*x = $1.1x from selling it. Similarly, if she sold the other ticket at a loss of $18, she got $x - $18 from selling it.
Since the difference in the selling prices of the two tickets is $36, we have $1.1x - ($x - $18) = $36. Solving this equation for x, we get $x = $36 / 0.1 = $360. Therefore, the cost of each ticket for Jessica was $360.
To determine whether Jessica made an overall profit or loss, we need to compare the total amount she received from selling the two tickets to the total cost of the tickets. The total amount she received from selling the two tickets was $1.1x + ($x - $18) = $1.1x - $18 + $x = $1.1x = $396. The total cost of the tickets was 2 * $360 = $720. Since $396 < $720, Jessica made a loss of $720 - $396 = $324 overall.

Describe probability.The field of mathematics known as probability studies numerical representations of the likelihood that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, with 0 generally signifying the event's impossibility and 1 generally signifying its certainty.
Here,
a) It doesn't matter what suit the first card is. Any of the suits may be drawn first, provided that the following four cards are taken from the same deck and have the same suit.
The deck contains 13 of each suit, so after the first card is pulled, there are only 12 of that suit remaining. There are then 11 remaining for the third card, 10 remaining for the fourth card, and 9 remaining for the fifth and final card. The deck will also contain one fewer card overall each time.
