What is the equation of the exponential graph shown?

Answer: B) 3 × 3 × 3 × 3 × 3

Concept:

In factorization, the easiest way is to divide the term multiple times by the least factor each time until the answer is not divisible. Then, multiply all the factors and the remainder together to get the factorization of a term.

Solve:

243 ÷ 3 = 81

81 ÷ 3 = 27

27 ÷ 3 = 9

9 ÷ 3 = 3

3 ÷ 3 = 1

Therefore, the prime factorization of 243 = 3 × 3 × 3 × 3 × 3

Let the width of the rectangle be "w".Then the length of the rectangle is given by "3 cm more than twice the width."Therefore, length (l) = 2w + 3.The area of a rectangle is given by the product of its length and width. Thus we can write an equation for the area of the rectangle.

A = l × w Substituting l and w in terms of each other we get; A = (2w + 3) × w ⇒ 2w² + 3w - 90 = 0This quadratic equation can be factored as (2w + 15)(w - 6) = 0.So the width of the rectangle can be either -15/2 (rejected) or 6 cm. And the length of the rectangle is (2 × 6) + 3 = 15 cm. The dimensions of the rectangle are 6 cm by 15 cm. The length of a rectangle is 3 cm more than twice the width. If the area of the rectangle is 90 square cm, find the dimensions of the rectangle.

The fee charged for the R 2, 500 withdrawal from TownBank would be R 33. 30.

To find the total fee charged to withdraw the sum of R 2, 500 from TownBank, the formula is :

= 3. 30 + R 1, 20 per R 100

The amount withdrawn was R 2, 500 so the total fee charged would be :

= 3. 30 + 1, 20 x ( 2, 500 / 100 )

= 3. 30 + 1. 20 x 25

= 3. 30 + 30

= 33. 30

= R 33. 30

In conclusion, the total fee charged was R 33. 30.

The population of the town in 2040 will be 9384.

According to the question,

We have the following information:

From 2006 to 2010, the population of a town declined to 22,000. The population is expected to continue to decline at a rate of 2.8% each year.

Rate of decline = 2.8/100

Rate of decline = 0.028

Number of years = 30 years (time between 2010 and 2040)

We know that the following formula is used to find the future population:

Future population = present population\((1-I)^{n}\) where I is the rate of decline and n is the number of years

Future population = 22000\((1-0.028)^{30}\)

Future population = 9384.49

Future population = 9384

Hence, the population of the town in 2040 will be 9384.

Answer:

a) To make x the subject of equation (2), we need to isolate x on one side of the equation. We can do this by adding 2 to both sides, and then dividing both sides by 6:

x - 2 = 6y

x = 6y + 2

b) We can now substitute the expression 6y + 2 for x in equation (1):

6y + 2 - 2y = 10

Simplifying the left-hand side, we get:

4y + 2 = 10

Subtracting 2 from both sides, we get:

4y = 8

Dividing both sides by 4, we get:

y = 2

Now we can substitute y = 2 back into either equation to find x. Let's use equation (2), since we have already rearranged it to make x the subject:

x = 6y + 2

x = 6(2) + 2

x = 14

Therefore, the solution to the simultaneous equations is x = 14 and y = 2.

Step-by-step explanation:

The correct option is option (b). The percent overall error rate for the given confusion matrix is approximately 37.5%.

In the confusion matrix, the diagonal elements represent the correct predictions, while the off-diagonal elements represent the incorrect predictions. The overall error rate is calculated by summing up the incorrect predictions and dividing it by the total number of predictions.

In this case, the total number of predictions is the sum of all the elements in the confusion matrix, which is 80 + 100 + 20 + 120 = 320.

The total number of incorrect predictions is the sum of the off-diagonal elements, which is 100 + 20 = 120.

The percent overall error rate is then calculated by dividing the total number of incorrect predictions by the total number of predictions and multiplying by 100:

(120 / 320) * 100 = 37.5%.

Therefore, the percent overall error rate is approximately 37.5%, which corresponds to option b.

yes, if the value of the coin is 1 dollar, then it will exceed the million dollars within 28 days.

It will depend on the original value of the coin, value that we don't know, so I will assume that the value of the coin is $1.

If this coin doubles each day, then the day zero its value is $1.

After one day its value is 2*$1 = $2

After another day its value is 2*$2 = $4

And so on, this is modeled by the exponential equation:

y = $1*(2)^x

Where y is the total value and x is the number of days.

After 28 days (this means we use x = 28) the value will be:

y = $1*(2)^28 = $268,435,456

That is a lot more than one million dollars.

Applying the linear pair theorem and the sum of interior angles of hexagon, we have:

Angle 7 = 92°

Angle 1 = 107°

According to the linear pair theorem/postulate, when two angles lie on a straight line, the sum of their measures equals 180 degrees.

Angle 7 lie on a straight line with 88°, therefore, applying the linear pair theorem, we have:

Angle 7 + 88 = 180

Subtract both sides by 88

Angle 7 + 88 - 88 = 180 - 88

Angle 7 = 92°

Also, using the linear pair theorem, we have:

Angle 5 = 180 - 64

Angle 5 = 116°

Angle 3 = 180 - 57

Angle 3 = 123°

Sum of interior angles of hexagon equals 720°, therefore:

Angle 1 + angle 3 + angle 5 + angle 7 + 118 + 164 = 720°

Plug in the known values

Angle 1 + 123 + 116 + 92 + 118 + 164 = 720

Angle 1 + 613 = 720

Subtract both sides by 613

Angle 1 + 613 - 613 = 720 - 613

Angle 1 = 107°

By creating a graph that shows the relationship between the number of carts and the space required, the store can better design the space for rows of nested shopping carts.

To design the space for rows of nested shopping carts in a store, a graph can be created that shows the relationship between the number of carts and the amount of space required.

This can be done by plotting the number of carts on the x-axis and the space required on the y-axis.The appropriate labels for each axis are "Number of Carts" for the x-axis and "Space Required" for the y-axis.

The scale for the x-axis would depend on the maximum number of carts that the store wants to accommodate, while the scale for the y-axis would depend on the amount of space that each cart takes up.

The movable points on the graph can be used to illustrate different scenarios.

For example, if the store wants to know how much space would be required for 50 carts, the movable point can be placed at 50 on the x-axis, and the corresponding space required can be read off the y-axis.

Similarly, if the store wants to know how many carts can be accommodated in a given amount of space, the movable point can be placed at the desired space on the y-axis, and the corresponding number of carts can be read off the x-axis.

Answer:

x = 8

length is 12 meters

width is 9 meters

Step-by-step explanation:

P = 2l + 2w

where l is the length and w is the width.

(There are two sides with the same length, and two sides with the same width.)

Let l = x + 4 and w = 2x - 7

so 2(x+4) + 2(2x-7) = 42

Distribute the 2s

2x + 8 + 4x - 14 = 42

Combine like terms

2x + 4x + 8 - 14 = 42

Group

6x - 6 = 42

Add 6 to both sides

6x = 48

Divide 6 on both sides

x = 8

Plug back in

l = 8 + 4 = 12 meters

and w = 2(8) - 7 = 16 - 7 = 9 meters

Double-check: 2 * 12 + 2 * 9 = 24 + 18 = 42

If a scientist has 315 cells in a container and she expects the number of cells to triple in one day then the number of cells the scientist will have after one day is equal to 945.

The number of cells the scientist will have after one day can be figured out using multiplication. Multiplication is one of the four parts of arithmetic. It can be considered as the opposite of division and can be defined as the repeated addition of the same number or groups of equal sizes.

The number of cells the scientist will have after one day can be calculated as follows;

Number of cells = 315

As it is expected to triple, which means that it is expected to increase three times in amount.

Therefore;

3 × number of cells in the container

3 × 315 = 945

Hence, the number of cells the scientist will have after one day is calculated to be 945.
