Answer: the maximum profit per holiday is 31050 pesos
Step-by-step explanation:
y=-0,015x²+45x-2700 (1)
It`s a quadratic equation like y=ax+bx+c
Therefore, the value of x at which y is maximal is:
[tex]\displaystyle\\x=\frac{-b}{2a} \\\\x=\frac{-45}{2(-0.015)} \\\\x=\frac{-45}{-0.03} \\\\x=\frac{45(100)}{0.03(100)}\\\\x=\frac{4500}{3} \\\\x=\frac{3(1500)}{3} \\\\x=1500[/tex]
Substitute the value of x into equation (1):
[tex]y=-0,015(1500^2)+45(1500)-2700\\\\y=-0.015(15*10^2)^2+67500-2700\\\\y=-0.015(15^2)(10^4)+64800\\\\y=-0,015*225*10^4+64800\\\\y=-150*225+64800\\\\y=-33750+64800\\\\y=31050 \ pesos[/tex]
At 59 F, crickets chirp at a rate of 76 times per minute, and at 65 F they chirp 100 times per minute. Write an equation in slope-intercept form that represents the situation.
The equation in slope-intercept form that represents the situation is y = 4x - 160.
Given,
At 59°F, crickets chirp at a rate of 76 times/minute
At 65°F crickets chirp at a rate of 100 times/minute
We have to write an equation in slope-intercept form:
Here,
(x₁, y₁) = (59, 76)
(x₂, y₂) = (65, 100)
Lets find the slope.
m = (y₂ - y₁) / (x₂ - x₁)
m = (100 - 76) / (65 - 59)
m = 24/6
m = 4
That is, the slope is 4.
Now, substitute this in the slope-intercept form:
y = mx + b
100 = 4 × 65 + b
100 = 260 + b
b = -260 + 100
b = -160
Therefore, the equation in slope-intercept form that represents the situation is y = 4x - 160.

Step-by-step explanation:
Assume a profitable economic well produces an average income of $23 million, while the average cost of a dry hole is $1.2 million. How much profit can be expected from a 100-well drilling program?
The most appropriate choice for revenue and profit will be given by-
Profit expected from a 100-well drilling program = $[tex]146.2[/tex]
What is revenue and profit?
Total income generated by sale of goods and service is called revenue.
If [tex]p[/tex] is the cost of producing one unit of a commodity and [tex]q[/tex] is the number of units of the commodity, then the product of [tex]p[/tex] and [tex]q[/tex] gives the revenue.
If the revenue obtained by selling a commodity is more than the cost, difference between revenue and cost gives the profit.
Here,
Number of economic wells = 11
An economic well produces an average income of $23
Revenue obtained = $[tex]$[/tex][tex](23 \times 11)[/tex]
Number of dry wells = [tex]100 - 11[/tex]
= [tex]89[/tex]
Average cost of a dry hole is $1.2 million
Cost of 89 dry holes = $[tex]$[/tex][tex](89 \times 1.2)[/tex]
= $[tex]106.8[/tex]
Profit = Revenue - cost
= $[tex](253-106.8)[/tex]

Why can we consider the sample mean in random samples of size n from a given population to be a random variable?.
The sample mean is indeed a random variable because the value of the sample mean depends on the characteristics of the specific random sample. The sample size multiplied by the population mean yields the expected value of the sample sum.
What is random?
The lack of pattern or predictability in events, whether it be apparent or real, is referred to as randomness. Sometimes there is no order or discernible pattern or combination in a random series of events, symbols, or processes.
What is mean?
A collection of two or more numbers' mean is simply their simple mathematical average. There are various methods for calculating the mean for a given collection of numbers, including the arithmetic mean approach, which adds up the series' values, and the geometric mean method, which averages a group of products. The majority of the time, all of the fundamental approaches to calculating a basic average, however, yield the same rough result.
As the population is a huge number and not linear in growth we prefer to take random variable.

Find the 7th term in the
sequence
-4, -8,-16, . . .
Answer: -512
Step-by-step explanation:
to answer this problem you need to understand the sequence and hen extrapolate the sequence out until you get to the seventh term (which would be your answer).
looking at -4, -8, -16
First we clearly see that each number is a negative and an even number. going beyond this we see -4 goes into -8 twice and -8 goes into -16 twice (in other words the next number in the sequence is always double the proceeding number). Also, each number is an even factor of four which can help us with double checking at the end!
-4 --> (-4) + (-4) = -8 -8 --> (-8) + (-8) = -16 -16 --> (-16) + (-16) = -32 -32 --> (-32) + (-32) = -64 -64 --> (-64) + (-64) = (-120) + (-8) = -128 -128 --> (-128) + (-128) = (-200) + (-40) + (-16) = -256 -256 --> (-256) + (-256) = (-400)+(-100)+(-12) = -512Can also be seen as:
4 times (-2) = -8 4 times (-4)= -16 4 times (-8) = -32 4 times (-16) = -64 4 times (-32) = -128 4 times (-64) = -256 4 times (-128) = -512Double check by going back and reviewing you math as well as making sure each answer is even and divisible should be divisible by four!
I hope this helps!
P.S.
As this addition is rather tedious you could also times each previous answer by 2 .
example:
-64 times 2 = -128
(previous number in sequence) times 2 = (next number in sequence)

A rectangle as shown has a length of 11 centimeters and a width of 4.2 centimeters. A circle is drawn inside that touches the rectangle at two points. Which is the closest to the total area of the shaded region?A. 9.19 cm squaredB. 101.59 cm squared C. 60.05 cm squared D. 32.35 cm squared
The area of a rectangle can be calculated with this formula:
[tex]A_r=lw[/tex]Where "l" is the length and "w" is the width.
The area of a circle can be found with this formula:
[tex]A_c=\pi r^2[/tex]Where "r" is the radius of the circle.
Let be "d" the diameter of the circle shown in the picture. Since it touches the rectangle at two points, you can identify that:
[tex]d=w[/tex]Since the radius of a circle is half the diameter, in this case this is:
[tex]d=\frac{4.2cm}{2}=2.1\operatorname{cm}[/tex]Therefore, the area of the circle is:
[tex]A_c=\pi(2.1\operatorname{cm})^2=13.85\operatorname{cm}^2[/tex]Now you must find the total area of the rectangle. Knowing that:
[tex]\begin{gathered} l=11\operatorname{cm} \\ w=4.2\operatorname{cm} \end{gathered}[/tex]You get:
[tex]A_r=(11\operatorname{cm})(4.2\operatorname{cm})=46.2\operatorname{cm}^2[/tex]In order to find the total area of the shaded region, you must subtract the total area of the rectangle and the area of the circle. Then, this is:
[tex]A_{sr}=46.2\operatorname{cm}-13.85\operatorname{cm}=32.35\operatorname{cm}^2[/tex]The answer is: Option D.

A regular octagon is a closed figure with equal-length sides and equal-sized interior angles.
Measure of interior angle = 135°
Measure of exterior angle = 45°
What is meant by regular octagon?A regular octagon is a closed figure with equal-length sides and equal-sized interior angles. It possesses rotational symmetry of order 8 and eight lines of reflective symmetry. The Schläfli sign "8" represents a regular octagon. A regular octagon's internal angle at each vertex is 135°. ( radians).
We know that for a regular polygon with n sides the measure of each of the exterior angle = 360/n
Also, the measure of each of the interior angles of the regular polygon with n sides = (n - 2) × 180 / n
We have n = 8 (octagon)
Therefore, the measure of each of the exterior angles is: 360/8 = 45
Measure of each of the interior angles is given by:
(8-2) × 180/8 = 1080/8 = 135
Measure of interior angle = 135°
Measure of exterior angle = 45°

Kesha is an hourly worker and is paid bi-weekly. Her wage is $25, and she is scheduled for 8 hours a day for 5 days a week. She also works 4 hours every other Saturday at time-and-a-half pay. How much is the gross income on Kesha’s paystub normally?(1 point) Responses $2,000 $2,000 $2,100 $2,100 $2,150 $2,150 $4,300
Answer:
$2,150
Step-by-step explanation:
GivensWe are given that Kesha is an hourly worker, is paid bi-weekly, and her wage is $25.
We are also told that she works 40 hours a week (derived from 8 hours a day for 5 days a week) and that she works 4 hours every other Saturday at time-and-a-half pay.
We are asked to find Kesha's gross income on her pay stub.
SolveFirst, determine her weekly wage by multiplying her hourly wage by the number of hours she works each week:
[tex]\$25 \times 40 = \$1,000[/tex]
Then, multiply this value by 2 since Kesha is paid bi-weekly (twice a month):
[tex]\$1,000 \times 2 = \$2,000[/tex]
Then, determine her time-and-a-half pay by first multiplying her hourly wage by 1.5:
[tex]\$25 \times 1.5 =\$37.50[/tex]
Then, multiply this value by 4 to represent the hours she works every other Saturday:
[tex]\$37.50 \times 4 = \$150[/tex]
NOTE: Since "every other Saturday" means twice a month, this is the same definition as bi-weekly. Therefore, no adjustments need to be made to this value.
Finally, add her time-and-a-half pay to her bi-weekly pay:
[tex]\$2,000 + \$150 = \$2,150[/tex]
Final AnswerTherefore, Kesha's gross income on her pay stub is $2,150.
In your own words, explain the relationship between the graph of a function and the graph of function's derivative.
Answer:
The derivative of a function in a point is the slope of the graph in that point, so the graph of the function's derivative shows the slope of the function at any point. It is useful because we can say if the function is increasing or decreasing using the graph of the function's derivative. Where the derivative is positive, the graph of the function is increasing and when the derivative is negative, the graph of the function is decreasing.

Here is the answer to the question the way it is asked, but the question is ridiculous. 1 kernel of popcorn has a mass of perhaps 1.5 g, so 1.25 g is reasonable. That means 1 kernel has a mass of 0.00125 kg, or 1.25 × 10^-3 kg. To state that 1 kernel of popcorn has a mass of 1.25 × 10^1 means that a kernel of popcorn has a mass of 12.5 kg which corresponds to a weight of approximately 27.6 lb. That is just ridiculous.
Using the ridiculous information given in the problem, then if 1 kernel has a mass of 1.25 × 10^1 kg, then 5.2 × 10^8 kernels have a mass of

= (1.25 × 5.2) × (10^1 × 10^8) kg
= 6.5 × 10^9 kg
Your number is correct, but don't forget the units.
Which algebraic expression is equivalent to the expression below?
8(3x - 5)
A.
24x - 40
B.
8x - 3
C.
8x - 8
D.
24x + 40
Answer: A
Step-by-step explanation:
Using the distributive property,
[tex]8(3x-5)\\\\=8(3x)-5(8)\\\\=24x-40[/tex]
Which type of transformation is described by (x,y)
(x,y) → (x-4, y+8)?
(x, y) => (x-4, y+8) is a transformation of 4 units left and 8 units up
How is the transformation described?
From (x, y) to (x-4, y+8) ,
(a) Let us consider x => (x - 4)
Consider x axis and the ' - ' sign
Here a point moves 4 units to the left
(b) Let us consider y => (y + 8)
Consider y axis and the ' + ' sign
Here a point moves 8 units upwards
What is a transformation?
A point, line, or geometric object can be changed in four different ways that are all collectively referred to as transformations. Translation, rotation, reflection, and expansion are the four different types of transformation. The pre-image is the shape of the object as it was originally, and the transformed shape of the object is termed the image. Every point is equally distant from a fixed line in a reflection. Rotation is the act of turning about a central point .Translation is where every point of the shape must translate the same amount and in the same direction. A dilation is a resizing. A form changes size when you adjust it; even so, it retains the same appearance.To learn more about transformation, refer:
