Part A: 2 points
Is this function increasing or decreasing? What does this mean in the context of the problem?
Part B: 2 points
What is the horizontal asymptote of the function? Interpret the meaning of the asymptote in
the context of the problem.
Answer:
A) decreasing. Salt concentration is being reduced.
B) 5%. The more 5% solution that is added, the closer the mixture becomes to 5%.
Step-by-step explanation:
A) Increasing values of x result in decreasing values of C(x), so the function is decreasing.
This means that when a lower concentration of salt solution is added to one of higher concentration, the result is a decrease in the concentration of salt in the mixture.
__
B) As x gets very large, C(x) approaches 5. The horizontal asymptote is C=5.
In the context of the problem, it means that as the solution contains more and more 5% brine, the concentration of salt in the mix approaches 5%.
A computer and printer cost a total of 1218. The cost of the computer is two times the cost of the printer. Find the cost of each item.
Answer:
Computer costs 812, printer costs 406
Step-by-step explanation:
Let c represent the cost of a computer and p, the cost of a printer
c + p = 1218 ....eq 1
but,
c = 2p ...eq 2
Substitute the value of c in eq 1
2p + p = 1218
3p = 1218
Divide both sides by p
p = 406
Substitute the value of p in eq 2
c = 2 * 406
c = 812

Answer:
1/4, -1/8, and 1/16
Step-by-step explanation:
Geometric sequence: -2, 1, -1/2, ....
Geometric sequence means there is a common ratio.
so from -2 , the next term is -2*r , and the next term is -2*r*r
-2r = 1, means r = -1/2
then next after -1/2, is 1/4,
and then... -1/8, and then 1/16
In a geometric sequence, each term is found by multiplying the previous term by a constant ratio. The next three terms in the sequence are 1/4, -1/8, and 1/16.
Explanation:In a geometric sequence, each term is found by multiplying the previous term by a constant ratio. In this sequence, the common ratio can be found by dividing each term by its previous term.
-2 ÷ 1 = -2
1 ÷ -2 = -1/2
The next three terms in the sequence can then be found by multiplying each term by the common ratio.
-1/2 × (-1/2) = 1/4
1/4 × (-1/2) = -1/8
-1/8 × (-1/2) = 1/16
Therefore, the next three terms in the geometric sequence are 1/4, -1/8, and 1/16.

The ratio of the number of girls in choir is 5 to 4 there are 60 girls in choir how many boys are in choir
Answer:75
Step-by-step explanation:
The number of boys in the choir can be calculated by setting up a proportion based on the given ratio of 5 girls to 4 boys. With 60 girls in the choir, solving the proportion indicates that there are 48 boys in the choir.
Explanation:This question deals with the concept of ratios. In this context, the ratio of girls to boys in choir is given as 5 to 4, which means for every 5 girls, there are 4 boys. As there are 60 girls in the choir, we can determine the number of boys by setting up a proportion.
First, let’s set our ratio to match the girl to boy ratio from our question, which is 5 to 4 or 5/4. Then we set that equal to a ratio of the number of girls to x (the variable we're using to figure out the number of boys), which will be 60 to x, or 60/x.
So, 5/4 = 60/x. Then, we cross-multiply to solve for x, which results in 5x = 240. We then solve for x by dividing each side by 5. So, x = 240 ÷ 5 = 48. This means there are 48 boys in the choir.

Scott paid 19.99 for a 7.98-kg bag of dog food. A few weeks later, he paid 20.38 for an 8.39-kg bag at a different store. What is the unit price for each bag
Answer:
Store 1: 19.99/7.98 = 2.51
Store 2: 20.38/8.39 = 2.43
Step-by-step explanation:
unit price is per 1 kg...so you will divide
Store 1: 19.99/7.98 = 2.51
Store 2: 20.38/8.39 = 2.43
The unit price of the first bag of dog food is $2.50 per kg, and the unit price of the second bag is $2.43 per kg.
Explanation:
To determine the unit price for each bag of dog food, we need to divide the total cost of the bag by the weight of the bag. The unit price will tell us the cost per kilogram of dog food. Let's calculate the unit price for each bag.
For the first bag:
Cost = $19.99
Weight = 7.98 kg
Unit price = Cost ÷ Weight
Unit price = $19.99 ÷ 7.98 kg
For the second bag:
Cost = $20.38
Weight = 8.39 kg
Unit price = Cost ÷ Weight
Unit price = $20.38 ÷ 8.39 kg
Let's perform the calculations:
First bag's unit price: $19.99 ÷ 7.98 kg = $2.50 per kg (rounded to two decimal places)Second bag's unit price: $20.38 ÷ 8.39 kg = $2.43 per kg (rounded to two decimal places)So the unit prices are $2.50 per kg for the first bag and $2.43 per kg for the second bag.

Figure WXYZ is transformed using the rule . Point W of the pre-image is at (1, 6). What are the coordinates of point W" on the final image? (–5, 8) (–3, –8) (5, –8) (3, 8)
The final image is:
[tex]\boxed{W''(3,8)}[/tex]
Explanation:Here we have two rules. The first one is a reflection across the y-axis and the second one is a translation. Let's apply these rules in two steps:
First rule:
Reflection across the y-axis:
[tex](x,y)\rightarrow (-x,y)[/tex]
By following this rule, you must multiply the x-coordinate of the point by -1. So here we reflect point W. Then:
[tex]W'(-1,6)[/tex]
Second rule:
[tex]T(x+4,y+2)[/tex]
This transformation shift each point 4 units to the right and 2 units up. Here we shift point W' that was previously transformed. Then:
[tex]W''(x,y)=W''(-1+4,6+2) \\ \\ \boxed{W''(x,y)=W''(3,8)}[/tex]
Applying the transformations, it is found that the coordinates of point W'' on the final image are (3, 8).
----------------------------------
The first transformation is a reflection across the y-axis, which has rule [tex](x,y) \rightarrow (-x,y)[/tex]Applying for W(1,6), we get W'(-1,6).The second transformation is a translation defined by [tex]T(x,y) \rightarrow T(x + 4, y + 2)[/tex].Applying for W'(-1,6), we get W''(3,8), as [tex]-1 + 4 = 3[/tex] and [tex]6 + 2 = 8[/tex].A similar problem is given at https://brainly.com/question/10547006

Answer:
$210
Step-by-step explanation:
(Note: there is no mention of the teachers buying origami kits so I will assume it's irrelevant)
We have 10 origami books, each of which is $24, so the total cost of the books is 10 * 24 = $240. We have 100 packs of origami paper, each of which is $6, so the total cost of the paper is 100 * 6 = $600.
Add these together: 240 + 600 = $840.
There are 4 teachers and each one will pay the same amount, so divide 840 by 4:
840 ÷ 4 = $210

An isosceles triangle has a perimeter of 75 cm. Each of the two equal sides is twice as long as the base. Find the length of the base.
Answer:
the base is 15cm
Step-by-step explanation:
Check out the photo and ask me if you need further explanation.
The base of the isosceles triangle is 15 cm, obtained by setting up the equation based on the given perimeter and the relationship between the base and the equal sides.
Explanation:Length of the Base of an Isosceles Triangle
Let's denote the base of the isosceles triangle as b, and each of the two equal sides as s. According to the problem, s is twice as long as b; hence, we can write s = 2b. Given the perimeter of the triangle is 75 cm, we can set up the equation 2s + b = 75, which simplifies to 2(2b) + b = 75, and further simplifies to 5b = 75. Solving for b, we get b = 75 / 5, which gives us b = 15 cm.
Therefore, the length of the base of the isosceles triangle is 15 cm.

Meghan unfolded a three dimensional solid and formed the two dimensional figure below. Select all the statements that apply to this figure
Answer:
The statements that apply to this figure are:
3. The surface area is the lateral area plus the area of the two circles.4. This is the net of a cylinder.
5. The lateral area is the circumference of the circle multiplied by the height of the solid.
Explanation:
First, analyze the 2D figure and imagine what it is in 3D: you may bend the left circle 90º, then roll it along the line of the rectangle all the way up and then bend the other circle 90º.
The rectangle will become the lateral walls of a cylinder and each circle a base.
Thus, the net corresponds to a cylinder.
Now, check every statementÑ
1. This is the net of a cone
FALSE. It is a cylinder2. The volume is found by adding up the areas of the circles and the rectangle.
FALSE. By adding up the areas of the circles and the rectangle you get the area of the cylinder.
3. The surface area is the lateral area plus the area of the two circles.
TRUE. The lateral area of the cylinder is equal to the area of the rectangle. The area of the two circles is the area of the bases of the cylinder.
By adding the lateral area and the area of the bases you get the total surface area of the cylinder.
4. This is the net of a cylinder.
TRUE. Explained above
5. The lateral area is the circumference of the circle multiplied by the height of the solid.
TRUE. The circumference of the circle is equal to the length of the rectangle. Thus, by multiplying this by the height of the rectangle, which is the same height of the solid, you get the area of the rectangle and that is the lateral area of the cylinder.
6. The solid has 3 faces, 6 edges and 4 vertices.
FALSE. The only edges of the cylinder are the rims of the bases and a cylinder does not have vertices.
Hence, the true statements that apply in the figure are:
The surface area is the lateral area plus the area of the two circles.This is a net of a cylinder.The lateral area is the circumference of the circle multiplied by the height of the solid.Cylinder:A cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance. These bases are normally circular in shape (like a circle) and the center of the two bases are joined by a line segment, which is called the axis. The perpendicular distance between the bases is the height, [tex]'h'[/tex] and the distance from the axis to the outer surface is the radius [tex]'r'[/tex] of the cylinder.
Here this unfold is of a cylinder as it has [tex]2[/tex] circulars bare and [tex]1[/tex] rectangle side of the surface.
Total surface area is equal to= Surface area of lateral area + 2 circular area.
Lateral area= height[tex]\times[/tex]circumference of the circle.
