Officials in a town use a function c to analyze traffic patterns. C(n) represents the rate of traffic through an intersection where n is the number of observed vehicles in a specified time interval. What would be the most appropriate Damian for the function

Answers

Answer: The domain of the function should be whole numbers.

This functions counts the number of cars that pass through an intersection as the domain (or input). Therefore, we would start counting at 0 and go up for each car.

The set of numbers {0, 1, 2, 3, 4, 5, 6, 7 ....} are called the whole numbers.

The most appropriate domain for [tex]\( C(n) \)[/tex] is non-negative integers, representing the count of vehicles observed.

The most appropriate domain for the function [tex]\( C(n) \)[/tex], which represents the rate of traffic through an intersection based on the number of observed vehicles [tex]\( n \)[/tex] in a specified time interval, would be all non-negative integers. This is because the number of vehicles observed [tex](\( n \))[/tex] can only be a whole number (you can't have a fraction of a vehicle), and it can't be negative.

So, the domain of [tex]\( C(n) \)[/tex] would be:

[tex]\[ \text{Domain: } n \in \{0, 1, 2, 3, \ldots\} \][/tex]

This means [tex]\( n \)[/tex] is any non-negative integer.

the points (10, 6) and (7, u) fall on a line with a slope of -4/3. what is the value of u?

Answers

Answer:
u = 10

Explanation:
slope can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)

We are given:
slope = -4/3
point (10,6) representing (x1,y1)
point (7,u) representing (x2,y2)

Substitute with the givens in the above rule and solve for u as follows:
slope = (y2-y1) / (x2-x1)
-4/3 = (u-6) / (7-10)
-4/3 = (u-6) / (-3)
-3 * -4 = 3 * (u-6)
4 = u - 6
u = 4 + 6
u = 10

Ian is going to water his plants is it reasonable to say he will fill the watering can with 3 liters of water explain

Answers

This is possible for a smaller watering can. 3 liters is about 3/4 of a gallon (imagine a jug of milk).

It is equivalent to 3000 ml, which would also be 100 ounces of water.(5 -20 oz bottles of water).

Final answer:

It is reasonable for Ian to fill a watering can with 3 liters of water for watering plants, as it falls within the typical range required by houseplants and should suffice for watering multiple indoor plants or a small garden.

Explanation:

To determine if it is reasonable for Ian to fill a watering can with 3 liters of water to water his plants, we should consider the capacity of common watering cans and the typical water requirements for houseplants. For example, a standard watering can might hold anywhere from 1 to 10 liters of water, and most indoor plants generally require between 0.25 and 1 liter of water per week, depending on their size and the environmental conditions.

If Ian has several plants or a few large plants, 3 liters of water might be a perfectly reasonable amount for him to use. Without knowing the exact number and size of the plants, it is difficult to provide a precise answer, but in general, 3 liters is within a normal range for watering multiple houseplants.

For a substantial garden or larger outdoor plants, 3 liters might even be on the lower end, and multiple trips to the tap may be necessary. Thus, it is indeed reasonable to say that Ian will fill the watering can with 3 liters of water for watering plants.

Spin a spinner numbered 1-8 two times, land on two the first time and
land on a factor of 8 the second time

Answers

The correct probability is 1/16.

Explanation:

There is 1 section marked 8 out of 8 sections.  This makes the probability of landing on an 8 1/8.

The factors of 4 on this spinner are 1, 2, 4 and 8.  This makes 4 sections out of 8, which makes the probability of landing on a factor of 8 equal 4/8=1/2.

Together, the probability of both events would be 1/8(1/2) = 1/16.

Answer:

Required probability = 1/16

Step-by-step explanation:

When we spin a spinner numbered 1-8, we find that each spin is independent of the other.

HEnce probability for getting any number from 1 to 8 will be equal to 1/8 and remain the same for each spin.

So Probability on two for the first time and factor of 8 on the second time

=Prob (landing on 2)*Prob (landing on any factor of 8)

P(landing on 2) = 1/8

Factors of 8 are 1,2,4,8

Prob (landing on factor of 8) = 4/8

Hence required prob = 1/8(4/8) =1/16

at a local animal shelter there are 12 small size dogs and 5 medium sized dogs everyday the small sized dogs are each given 12.5 oz of dry food and the medium sized dogs are each given 18 oz of the same dry food how many pounds of dry food does the shelter serve in one day

Answers

12*12.5=150 oz 18*5=90 oz 150+90=240 convert to pounds = 15 pounds

The shelter serves a total of 15 pounds of dry food per day, after calculating the food given to both small and medium-sized dogs and converting the total from ounces to pounds.

To calculate the total amount of dry food served at the shelter in one day, you must multiply the amount of food each dog consumes by the number of dogs of that size. Then, add the totals for each size category. Since the pound is the most suitable unit for this calculation, you need to convert the ounces of food into pounds. There are 16 ounces in one pound.

First, calculate the total food for small-sized dogs: 12 dogs × 12.5 oz each = 150 oz.Then, calculate the total food for medium-sized dogs: 5 dogs × 18 oz each = 90 oz.Combine the amounts: 150 oz + 90 oz = 240 oz of dry food total.Finally, convert ounces to pounds: 240 oz ÷ 16 oz per pound = 15 pounds of dry food.

Therefore, the shelter serves a total of 15 pounds of dry food in one day.

$27.99 shoes ; 7 1/2 tax find the total cost or sale price to the nearest cent

Answers

27.99x.075= 2.09925 or 2.10 Rounded
27.99+2.10= $30.09

Answer:

$The total cost or sale price  = $30.09

Step-by-step explanation:

The total cost or sale price is the absolute price of a commodity including the given tax.

From the question given, the tax is [tex]7\frac{1}{2}[/tex]% of the price. So that;

Tax = [tex]7\frac{1}{2}[/tex]% × 27.99

      = 0.075 × 27.99

      = 2.09925

∴ Tax  = $2.09925

The total cost or sale price = price + tax

                                             = $27.99 + $2.09925

                                            = $30.08925

The total cost or sale price  = $30.09

Two congruent triangles fit together to form a parallelogram with a base of 14 inches and a height of 10 inches. What is the area of each triangle?

Answers

To find the answer you will find the area of the parallelogram by multpltig the base (14 in) by the height (10 in).

After this you will divide the answer of 140 square inches by 2 because the area each congruent triangle would be half of the total area.

The answer is 70 square inches for each triangle.

Final answer:

The area of each triangle is 140 square inches.

Explanation:

The area of a triangle is given by the formula A = ½ × base × height.

In this case, the base of the parallelogram is 14 inches and the height is 10 inches.

Since two congruent triangles form the parallelogram, we can consider one of the triangles.

Let's call the base of the triangle 'b' and the height 'h'.

We have the equation A = ½ × b × h = 14 × 10 = 140 square inches.

Therefore, the area of each triangle is 140 square inches.

You didn't give the fourth zero, but the answer is still false. If you have a root or an imaginary number as a zero, then its conjugate is also a zero. So if 8i is a zero, then -8i must also be a zero, and if 4i is a zero, then -4i must be a zero, with those zeros and -4, the number of zeroes exceeds the number of zeroes that a fourth degree polynomial can have.

The given statement is false, as a fourth degree polynomial with real coefficients -4, 8i,+4i cannot be formed it will form three degree or cubic polynomial as given by f(x) = (x + 4)(x - 8i)(x - 4i)

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

Polynomials can be classified based on degree as linear, quadratic, cubic, fourth degree.

Let f(x) represent the function with zeros 4​, 8i ​, and 4i. Hence:
