The equation that represents the number of zombies after 4 hours is the exponential function N(4) = 6 * (4)⁴.

What is an exponential function?

The formula for an exponential function is f (x) = aˣ, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0. The exponential curve is influenced by both the exponential function and the value of x. Depending on the exponential function, an exponential curve might increase or decrease. A quantity should have either exponential growth or exponential decay if it regularly increases or decreases by a predetermined percentage.

When there is exponential growth, the quantity grows initially extremely slowly and subsequently quickly. Throughout time, the rate of change quickens.

With exponential decay, the quantity initially falls very quickly and then gradually. The speed of change slows over time.

The number of zombies in the beginning = 6

It is said that it quadruples in size every hour.

So,

After one hour it becomes = 6 * 4

After two hours it becomes = 6* 4 * 4

The size increases as an exponential function.

If the number of hours passed is x, then the number of zombies can be written as the following exponential function.

N(x) = 6 * (4)ˣ

where the number of zombies is N(x).

Therefore the equation that represents the number of zombies after 4 hours is the exponential function N(4) = 6 * (4)⁴.

Airplane A traveled at a faster rate. The solution has been obtained by using speed-distance-time relationship.

Speed is calculated by dividing the distance traveled by the time needed to complete the journey. Distance and speed are intimately associated but time and speed are not.

We are given that Airplane A traveled 1662 miles in six hours.

We know that Speed = Distance / Time

Using this, we get

⇒Speed = 1662 / 6

⇒Speed = 277 miles per hour

We are given for Airplane B that y = 922/3x , where x represents its rate of speed over the same six hours

So, from this we get,

⇒Speed = (922/3) / 6

⇒Speed = 922 / 18

⇒Speed = 51.22 miles per hour

Hence, Airplane A traveled at a faster rate.

What is ratio ?

A ratio is a quantitative comparison of two or more quantities or values, expressed as the quotient of one divided by the other. It is usually represented in the form of a fraction, using a colon, or by the word "to". For example, if there are 6 boys and 4 girls in a class, the ratio of boys to girls can be represented as 6:4, or 6/4, or 6 to 4. Ratios are often used to compare the relative sizes or amounts of two or more things, such as ingredients in a recipe, parts in a machine, or components in a financial statement.

The rate for a ratio of the two different quantities is the number of one quantity for each unit of the other quantity. In this case, the rate is the number of puppies per litter.

Mallory had 13 puppies in 2 litters, so the rate is:

13 puppies / 2 litters = 6.5 puppies per litter

A expression is  combination of numbers, variables, and mathematical operations like addition, subtraction, multiplication, and division. It is  as simple as single number, variable or  combination of them, or it can be complex combination of various terms connected by mathematical operators. Expressions are used to represent the mathematical relationships, formulas, and calculations

To add the expression (((56)x)78)9)24, you would need to simplify it using the order of operations (PEMDAS):

First, simplify the innermost parentheses:

The expression (56)x evaluates to 56 times x.

The expression 78 with the result of (56)x in parentheses evaluates to 78 times the result of (56)x, or 78(56x).

The expression 9 with the result of the previous step in parentheses evaluates to 9 times the result of the previous step, or 9(78(56x)).

c² = a²+b²

represent the two sides of x by a and b

from the big triangle

b = √ 29² - 12²

b = √ 841 -144

b = √ 697

Answer:

Let's call the price of a student ticket "s" and the price of an adult ticket "a".

From the first day's sales, we know that:

3s + 1a = 38

From the second day's sales, we know that:

3s + 2a = 52

We can use these two equations to solve for "s" and "a".

First, we'll use the first equation to solve for "a":

3s + a = 38

a = 38 - 3s

Next, we'll substitute this expression for "a" into the second equation:

3s + 2(38 - 3s) = 52

Simplifying and solving for "s", we get:

3s + 76 - 6s = 52

-3s = -24

s = 8

So the price of a student ticket is $8.

We can substitute this value back into the first equation to solve for "a":

3(8) + a = 38

24 + a = 38

a = 14

So the price of an adult ticket is $14.

Answer:

Step-by-step explanation:

First, we need to calculate the sale price of the tablet computer after the 14% discount is applied. To do this, we can multiply the original price by 0.86 (1 - 0.14), which gives:

Sale price = $707 x 0.86 = $608.02

Next, we need to add the sales tax to the sale price. To do this, we can multiply the sale price by 0.05 (5%), which gives:

Sales tax = $608.02 x 0.05 = $30.40

Finally, we can find the total cost of the tablet computer by adding the sale price and the sales tax, which gives:

Total cost = $608.02 + $30.40 = $638.42

Therefore, the total cost of the tablet computer with the discount and sales tax included is $638.42.

The analysis of the number of runners, can be presented as follows;

a. The sequence is a geometric sequence

b. r(3) = 72, which indicates that the number of runners after the third week is 72

c. r(6)/r(5) = (2/3)

d. The recursive rule for r(w) is that the number of  runners in a week is (2/3) × The number of passengers in the previous week

A sequence is an ordered list of items.

The number of passengers currently in the  running club = 243

The amount by which the  number reduces each week =  2/3 the number in the previous week.

a. Therefore, the number of passengers each week can be presented as follows;

First week = 243

Second week = (2/3)  × 243 =  162

Third week = (2/3)³ ×  243

Therefore, the number  of runners in the nth week is; an= (2/3)ⁿ × 243, which is a geometric sequence

b. The number of runners in the wth week, r(w) =  2/3)^w × 243,

Therefore; r(3)  = (2/3)³ × 243  = 72

The meaning of the value is that the number of runners in the third  week, r(3) =  72 runners

c. r(6))/(r(5)) can be obtained as follows;

r(6) = (2/3)^6 × 243

r(5) = (2/3)^5 × 243

r(6)/r(5) = ((2/3)^6 × 243)/( (2/3)^5 × 243) = (2/3)

d. The recursive formula can be obtained as follows;

The number of passengers in a specified week =  (2/3) × The number of passengers in the previous week

r(w + 1) = (2/3)^w  ×  243

Answer: There isn't an error, it's taxes

Step-by-step explanation:

Answer:

The percent error in the price can be calculated using the formula:

percent error = |(experimental value - actual value) / actual value| x 100%

In this case, the experimental value is the final price of $52 and the actual value is the initial price of $50. So we have:

percent error = |(52 - 50) / 50| x 100%

percent error = |2/50| x 100%

percent error = 4%

Therefore, the percent error in the price is 4%.
