a. To prove the product property for logarithms using a base of 3 and solutions of 3, 9, 27, 81, and 243, we can start with the equation: log3(xy) = log3x + log3y

Let's say we want to find log3(81 * 27)
We know that log3(81) = 4, and log3(27) = 3
So, log3(81 * 27) = log3(81) + log3(27) = 4 + 3 = 7

We can verify this by using the fact that we know the solution of log3(81*27) is 243, and 3^7 = 243.

b. To prove the quotient property for logarithms using a base of 3 and solutions of 3, 9, 27, 81, and 243, we can start with the equation: log3(x/y) = log3x - log3y

Let's say we want to find log3(81 / 27)
We know that log3(81) = 4, and log3(27) = 3
So, log3(81 / 27) = log3(81) - log3(27) = 4 - 3 = 1

We can verify this by using the fact that we know the solution of log3(81/27) is 9, and 3^1 = 9.

c. To prove the power property for logarithms using a base of 3 and solutions of 3, 9, 27, 81, and 243, we can start with the equation: log3(x^n) = n*log3x

Let's say we want to find log3(81^3)
We know that log3(81) = 4
So, log3(81^3) = 3 * log3(81) = 3 * 4 = 12

We can verify this by using the fact that we know the solution of log3(81^3) is 243, and 3^12 = 243.

In all the above examples, we can see that the properties are upheld, and we can use the log3(y) values of 3, 9, 27, 81, and 243 to prove the Product, Quotient and Power property of logarithms with base 3.

Sarah's new total cost will be $1,685.73 including 15% gratuity.

To find the new total cost, we can first calculate the cost of shipping, which is 2% of the total cost of the computer repair.

Shipping = 2% * 1,444.50 = 28.89

We can then subtract the shipping cost from the original total cost to find the cost of the computer repair, excluding shipping.

Computer repair cost (excluding shipping) = 1,444.50 - 28.89 = 1,415.61

Now we can add the 15% gratuity to the cost of the computer repair, excluding shipping:

Gratuity = 15% * 1,415.61 = 212.34

Finally, we can add the gratuity and shipping cost back to the original cost of the computer repair to find the new total cost:

New total cost = 1,444.50 + 28.89 + 212.34 = $1,685.73

So, Sarah's new total cost will be $1,685.73 including 15% gratuity.

The function f(x) = 4x/(x-16) has vertical asymptotes at x = 16.

To see this, we can factor the denominator:

f(x) = 4x/(x-16) = 4x/x - 16

As x approaches 16 from the left or right, the denominator x-16 approaches 0, but the numerator 4x does not. This means that the function approaches infinity or negative infinity as x approaches 16, indicating a vertical asymptote at x = 16.

To find the end behavior of the function, we can look at the behavior of the function as x approaches positive or negative infinity. We can see that f(x) = 4x/(x-16)

As x increases without bound, x-16 increases without bound. This means that the denominator becomes larger and larger, making the function approach 0 as x approaches positive infinity.

As x decreases without bound, x-16 decreases without bound as well, this means that the denominator becomes smaller and smaller, making the function approach 0 as x approaches negative infinity.

Therefore, the function has a vertical asymptote at x = 16 and approaches 0 as x approaches positive and negative infinity.

The scale of the model is 0.00017 ft/in, or in inches per foot.

To determine the scale of the model, we need to find the ratio of the size of the model to the size of the real room. We can use the information provided about the total surface area of the model to find this ratio.

The total surface area of the model is given as 2,304 square inches. We can find the total surface area of the real room by multiplying the lengths of the four walls and the floor.

The inside dimensions of the room are given as 8 ft x 12 ft x 8 ft x 12 ft x 8 ft = 8 x 12 x 8 x 12 x 8 = 92,160 sq ft

Now we can find the ratio of the size of the model to the size of the real room by dividing the surface area of the model by the surface area of the real room and converting it to inches per foot.

2,304 sq in / 92,160 sq ft = 0.025 sq in/ sq ft

To convert square inches to square feet we divide by 144, so 0.025 sq in/ sq ft = 0.025/144 = 0.00017 ft/in

Equations that depict the revenue from recycling electronics and appliances are:

The following calculation can be used to calculate how much money Solomon can make by recycling appliances:

p = $0.60a

Solomon's potential earnings from recycling electronics are represented by the equation p = $1.50e - $27.

Here,

p = amount earned

a = pounds of appliances recycled

e = number of electronics recycled

The equation that depicts Solomon's earnings when he makes the same amount of money would be the same as the equation that describes his earnings when recycling gadgets.

$1.50e - $27 = $0.60e

To determine the number of pounds:

Combine and add similar terms

$1.50e - 0.60e = $27

Answer: We can use the formula for the sum of an arithmetic series to find the number of pages in the Funny Book. The formula is:

S = n/2 (2a + (n-1)d)

Where S is the sum of the series, n is the number of terms, a is the first term, and d is the common difference.

In this case, the series is the page numbers, a = 1, d = 1, and we know that there is no page numbered "21" but the page numbered "20" is there.

The number of pages numbered 20 is 20, and the number of pages numbered 19 is 19. So n = 20 + 19 = 39

By substituting the values into the formula

S = 39/2 (2*1 + (39-1)1) = 3920 = 780

The greatest number of pages that the Funny Book can have if it contains a page numbered 20 but not any that are numbered 21 is 780.

The coordinates of the points C and D are:

What is cartesian coordinate system?

A Cartesian coordinate system in a plane is a system of coordinates that uniquely identifies each point by a pair of numerical coordinates. These numerical coordinates are the signed distances from two fixed perpendicular oriented lines to the point, measured in the same unit of length.

Given:

The coordinates of A and B are A(1, 3) and b(-1, 3).

We have to find the coordinates of point C and D.

We know that C and D are directly below A and B respectively. So the x-values must coincide.

Then we can say that:

C = (1, y)

D = (-1, y)

Now, remember that for a rectangle of length L and width W the area is:

A = W*L

In this case, the length is AB, then:

L = 1 - (-1) = 2

And the area is 10 square units, so:

10 = W*2

10/2 = W = 5

This means that:

AC = BD = 5

So the difference between the y-component of A and the y-component of C is 5 units

3 - y = 5

3 - 5 = y = -2

Hence,  the coordinates of the points C and D are:

C = (1, -2), D = (-1, -2)

The sum of all possible values for the common ratio is -1/2.

The formula for a convergent infinite geometric series is:  Sum  =  a / (1 - r)

where a = first term and r = common ratio.

Given that,

The first term = -3/2  =>   a = -3/2

Since it sums to twice the common ratio,  Sum = 2r.

Putting these together   --->   2r  =  (-3/2) / (1 - r)                      

multiplying both sides by 1 - r:

2r(1 - r)  =  -3/2                              

multiplying both sides by 2:

4r(1 - r)  =  -3                                

multiplying out the left-hand side:

4r - 4r2  =  -3                                  

rearranging the terms:

0  =  4r2 - 4r - 3                              

factor:

0  =  (2r - 3)(2r + 1)

Either  r = 3/2  or  r = -1/2

Since an infinite geometric series converges only when  -1 < r < r,  the possible answer 3/2 must be rejected.

Thus, r = -1/2

Step-by-step explanation:

First, calm down.

The area of the trapezoid cannot be found in a straightforward way.

Instead, what we need to do here is divide the trapezoid into two parts, a right triangle and a trapezoid.

Finding the area of the right triangle is easy. You just need to multiply the sides and divide it by 2.

Area of right triangle = 5*4/2 = 10

Next, you need to find the area of the trapezoid.

Area of trapezoid(small) = (2+1)*4/2 = 6

All you need to do now is add the area of these two together, and you get 16.

Answer:

A = 16 units²

Step-by-step explanation:

the area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height between the parallel sides b₁ and b₋₂

here h = 4 , b₁ = 6 and b₂ = 2

A = [tex]\frac{1}{2}[/tex] × 4 × (6 + 2) = 2 × 8 = 16 units²
