The exponential equation is N ( t ) = a ( b )^t , where a = 50 and b = 3

The exponential growth or decay formula is given by

x ( t ) = x₀ × ( 1 + r )ⁿ

x ( t ) is the value at time t

x₀ is the initial value at time t = 0.

r is the growth rate when r>0 or decay rate when r<0, in percent

t is the time in discrete intervals and selected time units

Given data ,

Let the number of bacteria in the culture at a given time be N ( t )

The culture increases by a factor of 2

So , the value of r = 200 % , r = 2

Now , when t = 0 , the number of bacteria in the culture N ( 0 ) = 50

So , the exponential equation is

N ( t ) = N ( 0 ) ( 1 + r )^t

Substituting the values in the equation , we get

N ( t ) = 50 ( 1 + 2 )^t

N ( t ) = 50 ( 3 )^t

On simplifying the equation , we get

N ( t ) = a ( b )^t , where a = 50 and b = 3

Hence , the exponential equation is N ( t ) = 50 ( 3 )^t

Step-by-step explanation:

1 cm is defined as 1/100 of a meter. One foot is defined as 1/3 of a yard or 12 inches in length. We know that, 1 inch = 2.54 cm and therefore, 23.5 centimeter = 9.252 inches

Centimeters :

The centimeter (cm) is the fractional part of the meter, the international standard unit of length, and equals approximately 39.37 inches. It is defined as 1/100 of a meter.

The centimeter is based on the SI unit of measurement and is equal to one hundredth of a meter as indicated by the prefix "centi". The metric prefix ranges from 10-18 to 1018 in decimal, and the base (metric in this case) has no prefix and a modulus of 1. Exploring the most commonly used metric prefixes such as kilogram, mega, giga, tera, centi, milli, micro, and nano can be useful for quickly navigating metric units.

Inch:

Inches is a unit of length or distance in several systems of measurement, including traditional American units and British Imperial units. An inch is defined as 1/12 of a foot, so 1/36 of a yard. By modern definition, 1 inch equals 25 exactly 4 mm.

The term "inch" comes from the Latin unit "uncial", equivalent to "1/12" in Roman terms. There were several standards for inches in the past and the current definition is based on international yards. One of the earliest definitions of an inch was based on a barley grain, where an inch equals the length of three dry round grains of barley laid end to end. Another version of the inch is believed to be derived from the width of a person's thumb, where length was obtained by averaging the widths of three thumbs (small, medium, and thumb).

By multiplying  the value in centimeters by the conversion factor 0.3937007874021.

So, 23.5 centimeters = 23.5 × 0.39370078740213

                                   = 9.25196850395 inches.

The numerical values of x and y are 14 and 54 respectively.

The sum of angles on a straight line is equal to 180 degrees.

From the diagram, angle (9x + 2)° and angle (5x - 18)° are on a straight line,

Since the sum of angles on a straight line is equal to 180 degrees.

(9x + 2)° + (5x - 18)° = 180°

Solve for x

9x + 2 + 5x - 18 = 180

14x - 16 = 180

14x = 180 + 16

14x = 196

x = 196/14

x = 14

Now, angle (9x + 2)° and angle (2y + 20)° are corresponding angles.

Since corresponding angles are congruent.

(9x + 2)° = (2y + 20)°

Plug in x = 14 and solve for y

9( 14 ) + 2 = 2y + 20

126 + 2 = 2y + 20

128 = 2y + 20

128 - 20 = 2y

108 = 2y

2y = 108

y = 108/2

To answer this question, we can use a Venn diagram to visualize the data and find the number of participants that shopped in each category.

First, we'll create a venn diagram with three circles, one for each store (BJ's Wholesale Club, Sam's Club, and Costco). Then, we'll fill in the data from the question.

1. Start with the center of the venn diagram, where all three circles overlap. This represents the 5 participants who shopped in all three stores.
2. Next, fill in the overlapping sections between two circles. These represent the participants who shopped in two of the stores, but not the third.
- BJ's Wholesale Club and Sam's Club: 15 - 5 = 10
- BJ's Wholesale Club and Costco: 16 - 5 = 11
- Sam's Club and Costco: 12 - 5 = 7
3. Finally, fill in the sections that do not overlap with any other circles. These represent the participants who shopped in only one of the stores.

In the first week, it grew from 500 to 1000

1000 / 500 = 2

In the second week, the growth is from 2000 to 1000

2000 / 1000 = 2

m = Δy/Δx where, m is the slope

Given:

Answer: Yes

Step-by-step explanation:

We don't know the value of n and you are subtracting it from both sides.

A linear function has a constant rate of change, which means that the change in the value of y is proportional to the change in the value of x. This means that if we plot the points (x,y) for a linear function, they will fall on a straight line.

To determine which of the tables represents a linear function, we can calculate the rate of change between the points. If the rate of change is the same for all pairs of points, then the table represents a linear function.

For the first table:

Rate of change between (−2,4) and (−1,1) = (1−4)/(−1−(−2)) = −3

Rate of change between (−1,1) and (0,−2) = (−2−1)/(0−(−1)) = −3

Rate of change between (0,−2) and (1,−5) = (−5−(−2))/(1−0) = −3

Rate of change between (1,−5) and (2,−8) = (−8−(−5))/(2−1) = −3

Since the rate of change is constant (equal to −3) for all pairs of points, the first table represents a linear function.

For the second table:

Rate of change between (−2,4) and (−1,1) = (1−4)/(−1−(−2)) = −3

Rate of change between (−1,1) and (0,0) = (0−1)/(0−(−1)) = 1

Rate of change between (0,0) and (1,1) = (1−0)/(1−0) = 1

Rate of change between (1,1) and (2,4) = (4−1)/(2−1) = 3

Since the rate of change is not constant (it changes from −3 to 1 to 3), the second table does not represent a linear function.

For the third table:

Rate of change between (2,−2) and (2,−1) is undefined since x does not change.

Rate of change between (2,−1) and (0,0) = (0−(−1))/(0−2) = 0.5

Rate of change between (0,0) and (2,2) = (2−0)/(2−0) = 1

Rate of change between (2,2) and (2,−2) is undefined since x does not change.

Since the rate of change is not constant (it changes from undefined to 0.5 to 1 to undefined), the third table does not represent a linear function.

For the fourth table:

Rate of change between (0,−2) and (1,1) = (1−(−2))/(1−0) = 3

Rate of change between (1,1) and (2,0) = (0−1)/(2−1) = −1

Rate of change between (2,0) and (3,1) = (1−0)/(3−2) = 1

Rate of change between (3,1) and (4,−2) = (−2−1)/(4−3) = −3

Since the rate of change is not constant (it changes from 3 to −1 to 1 to −3), the fourth table does not represent a linear function.

Therefore, the only table that represents a linear function is the first one.

The total volume of all the tents is 1920 cubic feet

From the question, we have the following parameters that can be used in our computation:

Number of tents = 6

Base area of the tents = 96 square ft

Height of the tent = 10 ft

The total volume of all the tents is calculated as

Volume = Number of tents * Base area of the tents * Height of the tent/3

Substitute the known values in the above equation, so, we have the following representation

Volume = 6 * 96 * 10/3

The bedroom has a surface space of 17.4225 m² and the closet has a surface area of 2.5875 m².

In mathematics, the area is a measure of the amount of two-dimensional space taken up by a shape. It is a scalar quantity, meaning it has only magnitude and no direction. The unit of measurement used for area depends on the units used for the length of the sides of the shape. Common units used to measure area include square centimeters, square meters, square inches, and square feet. The formula for finding the area of a shape depends on the specific type of shape. For example, the area of a rectangle is given by the formula A = lw, where l is the length and w is the width of the rectangle. The area of a triangle is given by the formula A = (1/2)*bh, where b is the base and h is the height of the triangle.

Here,

area of bedroom=l*w

l=5.05 m

w=3.45 m
