The expression [tex]3log_b(8) - log_b(7)[/tex] written as a single logarithm is [tex]log_b(\frac{512}{7})[/tex].

Given the logarithmetic expression in the question:

[tex]3log_b(8) - log_b(7)[/tex]

To rewrite the expression [tex]3log_b(8) - log_b(7)[/tex] as a single logarithm, we can use the properties of logarithms.

Using the quotient rule property, which states that:

logₙ(a) - logₙ(b) = logₙ(a/b)

Applying the quotient rule:

First, rewrite [tex]3log_b(8) - log_b(7)[/tex] as:

[tex]log_b(8^3) - log_b(7)[/tex]

Now, since the base of the logarithm is the same (b), we can combine the two logarithms using the power rule, which states that logₙ(aᵇ) = b × logₙ(a).

[tex]log_b(\frac{8^3}{7})[/tex]

Simplify

[tex]log_b(\frac{512}{7})[/tex]

Therefore, the single logarithm is [tex]log_b(\frac{512}{7})[/tex].

Step-by-step explanation:

The formula for the average rate of change is [tex]\frac{f(b)-f(a)}{b-a}[/tex]. a = 0, b = 7, f(a) = 2, and f(b) = 3, We plus the numbers into the formula and get 0.1429 as our answer.

The domain of the exponential function is all real numbers.

The domain of a function refers to the set of all possible input values (also known as the independent variable) for which the function is defined.

For the exponential function y = 2ˣ + 6, the domain includes all real numbers.

This is because there are no restrictions on the input values that can be plugged into the function.

We can take any real number x, substitute it into the expression 2ˣ, and then add 6 to get a corresponding output value y.

Hence,  the domain of the exponential function is all real numbers.

We can see here that in order to known if the dollar belongs to the box or not, here is an explanation:

Let the single tickets = x

Answer:

Step-by-step explanation:

For Company C, the total cost in dollars, denoted as t, can be calculated using the following equation:

t = 27n + 18

In this equation, 27n represents the cost of the bracelets (charging $27 per bracelet), and 18 represents the flat rate for shipping any number of bracelets. By summing these two components, we obtain the total cost of the friendship bracelets from Company C in terms of the number of bracelets, n.

The value of x is equal to 15.1 units.

In Mathematics and Geometry, the measure of each interior angle of a regular polygon can be calculated by using this mathematical equation:

Interior angle = [180 × (n - 2)]/n

Where:

n represents the number of sides of a regular polygon.

Since this regular polygon can be decomposed into 46 triangles, it ultimately implies that it has 46 x 3 = 138 sides.

Therefore, the value of each interior angle can be calculated as;

Interior angle = [180 × (n - 2)]/n

Interior angle = [180 × (138 - 2)]/138

Interior angle = 169.6⁰

For the value of x, we have:

9.5x + 26.2 = 169.6

9.5x = 143.4

x = 15.1 units.

Answer:

h = -10

Step-by-step explanation:

The solution to the equation is h = -10. To solve for h, we need to isolate h on one side of the equation. We do this by adding 9 to both sides, subtract 4h from both sides, and add 5 to both sides. This gives us:

Negative 3 (h + 5) + 2 + 9 = 4 (h + 6) - 9 + 9

Negative 3h + 14 = 4h + 15

Negative 3h - 4h = 15 - 14

-7h = 1

h = -1/7

The cost per pound of sausage, s, and brisket, b is 10s + 14b = 100.5

We are given that;

First customer order= $21

Second customer order= $100.50

Now,

The two equations that can be used to create a system of equations are:

2s + 3b = 21 10s + 14b = 100.5

These equations are obtained by multiplying the cost per pound of sausage and brisket by the number of pounds ordered by each customer and setting them equal to the total cost for each customer. The variables s and b represent the cost per pound of sausage and brisket, respectively.

The required number of parrots out of 400 birds which are more than 18 cm tall is 391 parrots.

Given that the heights of adult parrots are normally distributed with a mean height of 34 cm and standard deviation of 8 cm.

The formula used to calculate the z-score for the height of 18 cm is

z = (x - mean) / standard deviation

By substituting the value of mean and standard deviation gives,

z = (18 - 34) / 8.

On simplification of numerator gives,

z= -16 / 8 = -2.

To find the proportion of parrots more than 18 cm tall by calculating the area under the standard normal curve to the right of z = -2 by the standard normal distribution table.

That implies, proportion = area to right of z = -2 is approximately equal to 0.9772.

The formula used to calculate the number of parrots that is more than 18 cm tall is  proportion × total number of parrots.

That implies, the number of parrots out of 400 birds which are more than 18 cm tall is 0.9772 × 400 = 390.88 ≈ 391.

To find the theoretical probability of Constance getting an orange ring from the coin-operated machine, we need to first understand what theoretical probability means. Theoretical probability is the likelihood or chance of an event happening based on the number of possible outcomes. In this case, the possible outcomes are the different colored rings that the machine contains.

We are given that the machine contains 5 white rings, 6 orange rings, 7 purple rings, and 15 pink rings.

Therefore, the total number of rings in the machine is 5 + 6 + 7 + 15 = 33.

The probability of Constance getting an orange ring can be calculated by dividing the number of orange rings by the total number of rings in the machine.

Therefore, the theoretical probability of Constance getting an orange ring is:

Area of composite figure:

8) To find the area of the composite figure, we have to add the area of rectangle, area of the top triangle and the area of the below triangle.

Rectangle:

            width = 2.5 m

          [tex]\boxed{\text{\bf Area of rectangle = length * width}}[/tex]

                                           = 3 * 2.5

Area of triangle:

              [tex]\boxed{\text{\bf Area of triangle =$ \dfrac{1}{2}*base*height$}}[/tex]

       Triangle1:

                    base = 3 m  ; height = 1.5 m

                   [tex]\sf Area \ of \ triangle1 = \dfrac{1}{2}*3*1.5[/tex]

       Triangle2:

               base = 3 m ; height = 2.5 + 1 = 3.5 m

               [tex]\sf Area \ of \ triangle2 = \dfrac{1}{2}*3*3.5[/tex]

                                          = 5.25 m²

Area of the figure = 7.5 + 2.25 + 5.25

                               = 15 m²

_______________________________________________________

9) To find area of the given area, add the area of rectangle1 and area of rectangle2.

      length = 5 ft ;  width =  5.5 ft

Rectangle1:

         Area of rectangle1 = 5 * 5.5

                                         = 27.5 ft²

Rectangle2:

           length = 8ft

           width = 10 - 5.5

                      = 4.5 ft²

           Area of rectangle2 = 8 * 4.5

                                           = 36 ft²

Area of the given figure = area of rectangle1 + area of rectangle2

                                       = 27.5 + 36

                                        = 63.5 ft²
