The Greatest Common Factor [GCF] means the LEAST DEGREE TERM possible, plus finding a common factor, in this case, between 9 and 13, which is 1, but writing it is unnecessary.

I am joyous to assist you anytime.

The greatest common factor of 13c and 9c³ is "c".

To find the greatest common factor (GCF) of 13c and 9c³, we need to determine the largest term that divides evenly into both expressions.

First, let's break down each expression into its prime factors:

13c = 13 x c

9c³ = 3²  x c³

Now, let's identify the common factors between the two expressions:

Common factors of 13c and 9c³: c

To find the GCF, we take the product of the common factors, considering the lowest exponent for each common factor:

GCF = c

Therefore, the greatest common factor of 13c and 9c³ is "c".

Answer:

A) A = 30m + 13           B = 28m + 15

B) Company B would charge $6 less for 4 mattresses

C) Company B would charge $12 less for 7 mattresses

Step-by-step explanation:

A. : Write equations to represent Company A's and Company B's total mattress cleaning charges for a certain number of mattresses. Define the variable  used in the equations.

Let's define the variable m to represent the number of mattresses to be cleaned.

For company A, we have a cost per mattress of $30 plus a fixed service fee of $13.  So the equation will be:

A = 30m + 13  

While company B charges $28 per mattress, with a fixed service fee of $15:

B = 28m + 15

That way, we have a good representation of both price structures, using a meaningful variable.

B. Which company would charge less for cleaning 4 mattresses? Justify your answer.

We just have to calculate the cost of cleaning 4 mattresses at both companies:

A = 30m + 13 = 30 (4) + 13 = 120 + 13 = $133

B = 28m + 15 = 28 (4) + 15 = 112 + 15 = $127

Company B would charge $6 less for 4 mattresses

C. How much money is saved by using the services of Company B instead of Company A to clean 7 mattresses?

Again, all we have to do is calculate the cost to clean 7 mattresses at both companies:

A = 30m + 13 = 30 (7) + 13 = 210 + 13 = $223

B = 28m + 15 = 28 (7) + 15 = 196 + 15 = $211

Company B would charge $12 less for 7 mattresses

Step-by-step explanation:

The geometric mean finds the typical value of a set of numbers through multiplication. To find the geometric mean of two numbers, you take the square root of the product of the two numbers.

So in this instance, multiply the two numbers together:

[tex]2*8=16[/tex]

And take the positive square root of the product:

[tex]\sqrt{16}=4[/tex]

The geometric mean is different than the commonly-used arithmetic mean, which finds the central value of a set of numbers by dividing the set's sum total by how many numbers are in the set.

Final answer:

The geometric mean of 8 and 2 is calculated as the square root of their product, which is 4.

Explanation:

To find the geometric mean of 8 and 2, we use the formula for geometric mean which is the square root of the product of the numbers. Therefore, the geometric mean of 8 and 2 is the square root of 8 multiplied by 2, which is √(8×2).

Let's calculate it step by step:

Hence, the geometric mean of 8 and 2 is 4.

Answer:

The possible dimensions are  y, 5y + 2 and y + 7.

Step-by-step explanation:

V = 5y^3 + 37y^2 + 14 y

y is common  to all 3 terms so

V = y(5y^2 + 37y + 14)

V = y (5y  + 2)(y + 7)

The expressions for the possible dimensions of the rectangular prism.

[tex]V = 5y^3 + 37y^2 + 14 y[/tex]. The possible dimensions are y, 5y + 2, and y + 7.

Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units,

then its volume is given as:

[tex]V = a\times b \times c \: \: unit^3[/tex]

The given expressions for the possible dimensions of the rectangular prism.

[tex]V = 5y^3 + 37y^2 + 14 y[/tex]

y is common to all 3 terms

so,

[tex]V = y(5y^2 + 37y + 14)\\V = y (5y + 2)(y + 7)[/tex]

By the comparison of the volume

[tex]V = a\times b \times c \: \: unit^3[/tex]

Therefore, the dimensions are a = y, b = 5y + 2, c = y + 7.

Answer:

Step-by-step explanation:

Replace tan^2(x) with sin^2 (x ) / cos^2(x)

2 sec(x) sin^3(x) = cos(x) * sin^2(x) / cos^2(x)    Cancel cos(x) with cos^2(x)

2 sec(x) sin^3(x) = sin^2(x) / cos(x)                     Multiply by cos(x) both sides

2 sec(x)*cos(x)*sin^3(x) = sin^2(x)                      Divide sin^2(x) both sides

Note sec(x) and   cos(x) will cancel when multiplied. giving you one

2 sin^3(x) / sin^2(x) = sin^2(x) / sin^2(x)             Do the division

2 sin(x) = 1                                                           Divide by 2

sin(x) = 1/2

x = sin-1(1/2)

Answer:

a: 5.25 b: -0.33

Step-by-step explanation:

a:

4x - 5 = 16

isolate the variable. this is done by putting only the variable on the left side and the numbers on the right side. when moving the 5 to the right side, it is counted as a -5 because of the minus in front. when moving it, be sure to change from - to + and vice versa.

4x = 16 + 5

4x = 21

x = 21/4

x = 5.25

b:

same process

35 + 3x - 11 = 23

move the 35 to the right, changing it to a -35

3x - 11 = 23 - 35

move the -11

3x = 23 - 35 + 11

3x = -12 + 11

3x = -1

x = -1/3

x = -0.33

Hope I could help! If you have any trouble, tell me in the comments.

Answer:

a. [tex]x=5.25[/tex]

b. [tex]x=-0.33[/tex]

Step-by-step explanation:

You need to solve for the variable "x" in each equation. Then:

a. You need to add 5 to both sides of the equation:

[tex]4x - 5 +(5)= 16+(5)\\\\4x= 21[/tex]

Now you need to divide both sides of the equation by 4, getting:

[tex]\frac{4x}{4}=\frac{21}{4}\\\\x=5.25[/tex]

b. You need to subtract 35 from both sides of the equation:

[tex]35 + 3x - 11-(35)= 23-(35)\\\\3x-11=-12[/tex]

Add 11 to both sides:

[tex]3x-11+(11)=-12+(11)\\\\3x=-1[/tex]

Now you need to divide both sides of the equation by 3, getting:

[tex]\frac{3x}{3}=\frac{-1}{3}\\\\x=-0.33[/tex]

Answer:

Step-by-step explanation:

The question is on calculating the confidence interval for a population mean

The general expression is

CI = x ± z * δ/√n   where;

CI = confidence interval,

 x = mean of sample,

 δ = standard deviation,

  n= is sample size

   z = z* value from standard normal distribution according to   confidence level given.

Given that;

n= 30   x =70.2    δ=10.51          z* for 95% CI = 1.96

Then applying the expression

CI = x ± z * δ/√n

To answer your question the graph will go 6 units to the right because the absolute value bar means the "-6" will become +6 so therefore 6 units right.

the pictures show the y=|x| & the y=|x-6|

Answer:

shift 6 units up

Step-by-step explanation:

When you are moving the graph from the center, you only have to put a 0 to the X and in that way you can know where is it going to be located

So it will end up like this:

y = lx - 6l= l0 - 6l= 6

So since its the absolute value, and in this case you have to move the graph upwards to the (0,6)

Answer:

C). 0 degrees

Step-by-step explanation:

The given equation is:

-4 + 6 sinx = -4 + 4 sinx

adding 4 on both sides:

4 - 4 + 6 sinx = 4 - 4 + 4 sinx

6sinx = 4sinx

dividing by 2 on both sides, we get:

6sinx/2 = 4sinx/2

3 sinx = 2 sinx

subtracting 2 sinx from both sides we get:

sin x = 0

x = sin⁻¹ (0)

x = 0 degrees

64 large boxes and 60 small boxes.

Here we must use the concept of multiples. A multiple of a number result of the multiplication of that number by an integer. For instance, 2, 4, 6, 8 are multiples of 2. The following chart shows our statement:

[tex]\begin{array}{cccccccccc}Number\,of\,boxes & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9\\Large & 8 & 16 & 24 & 32 & 40 & 48 & 56 & 64 & 72\\Small & 10 & 20 & 30 & 40 & 50 & 60 & 70 & 80 & 90\end{array}[/tex]

So we need to choose the number of small and large boxes such that the sum is 124 boxes of sunglasses and the number of large boxes is greater than the number of small boxes. From the table, the correct solution is:

64 large boxes and 60 small boxes because 64 + 60 = 124 and 64 > 60

Answer:

A merchant selling sunglasses can place 8 large boxes or 10 small boxes into a carton for shipping.

If a total of 124 boxes are shipped, then the large boxes in the cartons must be a multiple of 8 which means either 16,56,64, 72,104.

We will choose that multiple of 8, which when subtracted from 124, gives the number that is divisible by 10.

As the larger boxes are more in quantity, we will choose 64 and 104.

[tex]124-64=60[/tex]

[tex]64/8=8[/tex] cartons

[tex]60/10=6[/tex] cartons

Total cartons are =[tex]8+6=14[/tex]

Also, [tex]124-104=20[/tex]

[tex]104/8=13[/tex] cartons

[tex]20/10=2[/tex] cartons

So, total cartons shipped = [tex]13+2=15[/tex]

So, both can be answers. As any options are not given, you can solve it whatever way you like.

Answer:

Step-by-step explanation:

"Rectangular" includes "square," and in fact treating the rectangle as a square is the fastest way to "solve" this problem.  The perimeter of the rectangular area is 160 ft; dividing that by 4 yields 40 ft.  "40 ft square" describes the rectangle maximum area:  (40 ft)^2 = 1600 ft^2.

Alternatively, let W and L represent the width and length of the rectangle.  Then:

P = perimeter = 2W + 2L = 160 ft, or W + L = 80 ft, or W = 80 ft - L.

A = area = L*W = L(80 ft - L) = 1600 ft^2.  Rewriting this as a proper quadratic:

80L - L^2 - 1600 = 0, or  L^2 - 80L + 1600.  Note that this last result factors into (L - 40)^2 = 0, so L = 40 ft.  Then W = 80 ft - 40 ft = 40 ft.

This confirms that the max area is 1600 ft^2 = (40 ft)^2.

Answer:

see explanation

Step-by-step explanation:

Using the intercept form of the equation of a straight line

[tex]\frac{x}{a}[/tex] + [tex]\frac{y}{b}[/tex] = 1

where a is the x- intercept and b the y- intercept

here a = - 2 and b = 3, hence

[tex]\frac{x}{-2}[/tex] + [tex]\frac{y}{3}[/tex] = 1

Multiply through by - 6

3x - 2y = - 6 ← equation in standard form

Substitute x = 2 and y = 6 into the left side of the equation and if equal to the right side then (2, 6) lies on the line

left side = (3 × 2) - 2(6) = 6 - 12 = - 6

Hence line passes through (2, 6)
