3(-1.5x+2) = -5(0.5x - 0.4)
Answer:
x=2
Step-by-step explanation:
A small company is selling a new board game, and they need to know how many to produce in the future, After 12 months, they sold 4 thousand games; after 18 months, they sold 7 thousand games; and after 36 months, they sold 15 thousand games. 1) Could this information be reasonably estimated using a single linear model?
Yes, the information could be estimated using a single linear model.
How to get the linear model?
So remember that if a line passes through two points (x₁, y₁) and (x₂, y₂) the slope of that line can be written as:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Here we have 3 points:
(12, 4)
(18, 7)
(36, 15)
Where the first value represents the number of months and the second the number of games sold in thousands.
From these we can form 3 pairs and make 3 slopes, then we can take the mean slope:
[tex]\frac{7 - 4}{18 - 12} = 0.5\\\\\frac{15 - 7}{36 - 18} = 0.44\\ \\\frac{15 - 4}{36 - 12} = 0.46[/tex]
So the mean slope is:
s = (0.5 + 0.44 + 0.46)/3 = 0.467
y = 0.467*x + b
To find the mean value of b, we evaluate the function in the 3 points, and then we take the mean for b.
y - 0.467*x = b
for each point we have:
4 - 0.467*12 = b = -1.6
7 - 0.467*18 = b = -1.4
15 - 0.467*36 = -1.8
Taking the mean we get:
(-1.6 - 1.4 - 1.8)/3 = -1.6
So a line that models this can be:
y = 0.467*x - 1.6
to test the line, we can evaluate it in x = 36, we will get:
y = 0.467*36 - 1.6 = 15.212
Comparing, with the actual value, which is 15, we get a percentual error of:
100%*(15.212 - 15)/15 = 1.4%
As you can see, the percentual error with this line is really small, which means that the line is a really good estimation for the relation between the number of months and the number of games sold.

Find the indicated limit. Note that L'Hopital's rule may not apply or may require multiple applications.
lim e^9x -1-9x/x^2
x→0
Answer:
40.5
Step-by-step explanation:
Given the limit of the function expressed as:
[tex]\lim_{x \to 0} \frac{e^{9x}-1-9x}{x^2} \\[/tex]
Step 1: Substitute x = 0 into the function:
[tex]\lim_{x \to 0} \frac{e^{9x}-1-9x}{x^2} \\= \frac{e^{9(0)}-1-9(0)}{(0)^2}\\= \frac{{1-1-0}}{0}\\= \frac{0}{0} (ind)[/tex]
Step 2: Apply L'hopital rule
[tex]\lim_{x \to 0} \frac{d/dx(e^{9x}-1-9x)}{d/dx(x^2)} \\= \lim_{x \to 0} \frac{(9e^{9x}-9)}{(2x)}\\= \frac{(9e^{9(0)}-9)}{(2(0))}\\= \frac{9-9}{0} \\= \frac{0}{0} (ind)[/tex]
Step 3: Apply L'hopital rule again
[tex]\lim_{x \to 0} \frac{d/dx(9e^{9x}-9)}{d/dx(2x)}\\ = \lim_{x \to 0} \frac{81e^{9x}}{2} \\=\frac{81e^{0}}{(2)}\\= \frac{81}{2} \\= 40.5[/tex]
Hence the limit of the function is 40.5
Use substitution to solve the linear system of equations.

A man sold his house for $125000. After paying the broker his commission, the man received $116875. What was the brokers commission percentage?
Answer:
6.5%
Step-by-step explanation:
[tex]\frac{116875}{125000}[/tex] = [tex]\frac{187}{200}[/tex] = 0.935
0.935 -------> move the decimal point 2 places to the right ----> 93.5%
The man received 93.5%, meaning the broker received the rest.
100% - 93.5% = 6.5%
The brokers commission percentage was 6.5%

You can see by the shape of the white triangles within the large triangle that there were no rotations. The first similarity transformation shown in this image is a dilation, which we know because the white triangles are varying in size. The second similarity transformation depicted in this image is a translation, which we know because the white triangles are in various locations within the large triangle.

Answer:
$50
General Formulas and Concepts:
Math
Reading word problemsIdentifying operationsPre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightStep-by-step explanation:
We are given that Harry has a total of $72 as his starting amount (he got it from his uncle from his birthday).
We are also given that he spends some of that money to buy some clothes. Since he is spending money, that means we must remove the spent amount from the total.
We know that Harry spent $7 on a shirt, $5 on shoes, and $10 on jeans. In total, he spend $7 + $5 + $10 = $22.
Given he has $72 dollars to spend, he just spent $22 to pay for those items:
$72 - $22 = $50
Harry has $50 remaining.
How many different rectangles can you draw, that has an area of 28 cm sq. ? pls help me
Answer:
You can draw three rectangles:
1- 28 * 1.
2- 14*2
3- 7*4
Step-by-step explanation:
We have a total area of 28. If we use only integer numbers, we can find all the divisors of 28. The possible rectangles will be organized with them, taking into account that the product of them, which means the area should be 28.
28 = 1*2*2*7
We can organize them as follows:
R1: 28 = 1*28
R2: 28 = 2*14
R3: 28 = 4*7
Finally, we can conclude that there are only three possibilities
1- 28 by 1.
2- 14 by 2
3- 7 by4
The perimeters will be:
Perimeter 1 = 2x1 + 2x28 = 58
Perimeter 2 = 2x2 + 2x14 = 32
Perimeter 3 = 2x4+2x7 = 22

You may notice that the side lengths of the right triangle are in the ratio ...

B
D
3
A. 4.5
B. 5
C. 7.5
D. 10
Answer:
A) 4.5
Step-by-step explanation:
you can set up a ratio comparing AB/CB to (AB + BD)/5
3/2 = 3 + BD/5
cross-multiply to get 15 = 2(3 + BD)
15 = 6 + 2BD
9 = 2BD
9/2 = BD
The length of AD will be 7.5
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Lines BC and DE are both vertical.
Now,
Since, Lines BC and DE are both vertical.
So, We get by definition of proportionality;
⇒ AB / CB = (AB + BD) / 5
⇒ 3/2 = (3 + BD) / 5
⇒ 3×5 / 2 = 3 + BD
⇒ 15/2 = 3 + BD
⇒ 15/2 - 3 = BD
⇒ BD = 9 / 2
⇒ BD = 4.5
Thus, The length of AD = 3 + 4.5
= 7.5
Therefore, The length of AD will be 7.5.

Of the students in the photography club, 15% are not planning to go to the art show. There are 6 students not going to the art show. How many students are in the photography club? Use any strategy to solve.
Answer:
There are 40 students in the photography club.
Step-by-step explanation:
Given that:
Percent of people not going to art show = 15%
Number of people not going to art show = 6
Let,
x be the number of students in the photography club
15% of x = 6
[tex]\frac{15}{100}x=6[/tex]
0.15x = 6
Dividing both sides by 0.15
[tex]\frac{0.15x}{0.15}=\frac{6}{0.15}\\x= 40[/tex]
Hence,
There are 40 students in the photography club.
