Answer:

The domain is (-∞ , ∞)

The domain is continuous

Step-by-step explanation:

Here, we want to identify the domain of the linear function

The domain in this case can be represented by the set of all real numbers.

When we talk of the domain of a function, we are simply referring to the the range of values between the smallest value on the x-axis and the largest number on the x-axis

Hence, mathematically, we are simply considering the smallest value of b up to the largest value of b in this case. Where b simply represents the number of books

Thus, the domain here will be (-∞ , ∞)

On if the domain is discrete or continuous, we can see that the domain is continuous.

The domain is continuous simply because, the domain we have contains all the values and not some in the set of real numbers. If it had contain only some, then it would have been discrete. But since it contains all, it is continuous

On solving the provided question, we can say that x is an acute angle., cos(x) = 12 => x = cos^{-1}1/2=> x = 60

In Euclidean geometry, an angle is a shape made up of two rays, referred to as the angle's sides, that meet at a point in the middle known as the angle's vertex. Two rays can generate an angle that is in the plane where the rays are located. The meeting of two planes also creates an angle. They are referred to as dihedral angles. An angle is the shape created by two rays or lines that have a shared termination in plane geometry. The Latin word "angulus," which meaning "horn," is the source of the English term "angle." The vertex is the common terminal of the two rays, which are referred to as the sides of the angle.

In this problem, we're dealing with tan since we're working with the opposite and adjacent sides.

Remember SOH CAH TOA which means

Sin: Opposite over Hypotenuse,

Cos: Adjacent over Hypotenuse,

and Tan: Opposite over Adjacent

to remember what sin cos and tan means

So to set up a tan equation we have to do

tan(angle) = opposite side length/adjacent side length

The first equation is tan(25) = 50/x

because we have to find the length of the adjacent side so we can find how far away the tree is.

which is about 107.2 ft

The second equation is tan(50) = 50/x

because now we have to find how far away the tree is once the angle of elevation is twice the measure of the original angle (which is 50)

which is about 41.9 ft

After we subtract the two values, you get 65.3 so the answer is A.

I hope this helps!

Two make the angle from the top of the tree to the ground distance should be 41.95 ft.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

Given, The angle of elevation from a point on level ground to the top of a 50-ft tree is 25".

Since it makes a right-angle triangle with the tree that has a height of 50

Also given, At another angle from the ground that is twice the previous angle calculate the base.

Thus, the new angle will be 50°

thus, the base of the triangle:

Since. tan α = height/ base

in our case, α is 50°

height = 50 ft

tan α = 50 / base

base = 50/tan 50°

Base = 41.95 ft

therefore, Two make the angle from the top of the tree to the ground distance should be 41.95 ft.

Answer:

(2)(9) + 75 = 75+18

Step-by-step explanation:

(2)(9) + 75 = 75+18

The expression written as a product of a number and another sum is 3(25 + 8)

Given the expression 75 + 18, we are to write as a product of a number and another sum.

First we need to find the GCF of 75 and 18

75 = 3 * 25

18 = 3 * 6

Since 3 is common to both D+GCF, we can factor it out from the expression to have:

Step-by-step explanation:

(5.8 x 10⁴) + (7.17 × 10^6) =

(5.8 × 10⁴) + ( 717 × 10⁴)

A 1.5 meter wide sidewalk has been created completely around a garden that is 12 meters by 16 meters in size, bringing the total square footage to 285 meters.

An outdoor space that is 12 by 16 meters.

Its overall area increased to 285 square meters thanks to a pathway that was created completely around it.

Let 'x' represent the width of the installed route.

When a pathway is put in place, the garden's length changes.

x + 12 + x = 12 + 2x

Garden width, including pathway, is

x + 16 + x = 16 + 2x

Using new length and width, we can now find the area.

Area = Length . width

Area = (12 + 2x) (16+2x)

Total area 285

285 = (12 + 2x) (16 + 2x)

Now calculate the equation for x to find out the breadth of the pathway

285 = (12 + 2x) (16 + 2x)

285 = 192 + 56x + 4x²

192 + 56x +4x² - 285 = 285 - 286

4x² + 56x - 93 = 0.

A quadratic equation was obtained. Use the quadratic formula to solve for x.

x = -56 ±√56² -4 . (-93)/2.4

x = -56 ± 68 /2.4

x = -56 + 68 / 2.4 . x = -56 -68 / 2.4

x = 1.5.x = -15.5

There can be no negative width x.

B)the smallest number of coins which are worth at least the price of a toy, expecting possible change=30

C)the largest number of coins which are worth exactly the price of the toy with no change=86

What is currency-conversion?

Any medium of exchange that is used to pay for commodities, services, or products, as well as to estimate their value, is referred to as currency or money. Money in circulation in a nation, such as coins, notes, and bills, is referred to as currency. 100 cents to the dollar We multiply (here by 100) a larger unit (a dollar) to get a smaller unit (a cent), and we divide (here by 100) a smaller unit (a cent) to get a larger unit (a dollar).

We know that :

1 penny= 1 cent

1 nickel = 5 cents

1 dime = 10 cents

1 quarter = 25 cents

1 dollar = 100 cents

Ishan has:

43 pennies = 43 cents

31 nickels = 31 x 5 cents

               = 155 cents

21 dimes= 21 x 10

             =210 cents

10 quarters=10 x25

                 =250 cents

total money in cents=43+155+210+250

    Ishan has             =658 cents

Ishan wants to buy a toy car:

price of toy car=3 dollars 99 cents

                        = 3x100 cents+99cents

                        =399 cents

A)To make exactly 399 cents using larger value coins so that number of coins is smallest and no change:

399 cents = 250  cents+ 140  cents+ 5  cents + 4 cents

                 =10 quarters+ 14 dimes + 1 nickel + 4 pennies

Total coins = 10+14+1+4

                   =29 coins

29 coins which are worth exactly the price of the toy, so there is no change.

B)To make 399 cents using larger value coins so that number of coins is smallest possible change:

400 cents = 250  cents + 140  cents + 5  cents + 5 cents

                 =10 quarters+ 14 dimes + 2 nickels

Change=400-399=1 cent

Total coins = 10+14+2

                   =30 coins

30 coins which are worth at least the price of a toy, expecting possible change

C)To make 399 cents with least value coins so that we get the largest number of coins which are worth exactly the price of the toy with no change:

399 cents=34 cents + 155 cents + 210 cents

                =34 pennies + 31 nickels + 21 dimes

Total coins= 34+ 31+21

In this plot, the stem represents the tens digit, and the leaves represent the ones digit. For example, the stem "2" with leaves "2 3 5 8" means that there were four employees who worked between 20 and 29 hours.

To construct a stem-and-leaf plot for the given data, we need to organize the numbers into stems and leaves. The stem represents the tens digit, and the leaf represents the ones digit.

Let's take a look at the data:
30, 25, 12, 46, 31, 5, 22, 28, 8, 32, 23, 41, 39, 44

First, we separate the tens and ones digits for each number. For example, 30 has a stem of 3 and a leaf of 0.

Next, we arrange the stems in ascending order from left to right. The stems in this data set are 0, 1, 2, 3, 4.

Now, we place the leaves next to their respective stems. We can write the leaves in increasing order, but you could also choose to write them in decreasing order or any other order that makes sense to you. For this example, we'll write the leaves in increasing order.

Here's the completed stem-and-leaf plot:

0 | 5
1 | 2
2 | 2 3 5 8
3 | 0 1 2 9
4 | 1 4

In this plot, the stem represents the tens digit, and the leaves represent the ones digit. For example, the stem "2" with leaves "2 3 5 8" means that there were four employees who worked between 20 and 29 hours.

The domain of the function is a semicircle with a radius of 5 and centered at the origin, where y is non-negative.

The domain of a function is the set of all possible input values for which the function is defined. In this case, the function is defined as:

\(f(x,y) = \sqrt{y} + \sqrt{[25 - x^2 - y^2} ]\)

To find the domain of this function, we need to determine the values of x and y that would result in the function producing a real-valued output.

For the square root of y to be real, y must be non-negative. That is, y ≥ 0.

For the square root of [\(25 - x^2 - y^2\)] to be real, we must have:

\(25 - x^2 - y^2 \geq 0\\x^2 + y^2 \leq 25\)

This is the equation of a circle with radius 5 centered at the origin. Therefore, the domain of the function is the set of all points (x, y) that lie inside or on this circle and have y ≥ 0.

In interval notation, we can write:

Domain: {(x, y) |\(x^2 + y^2 \leq 25, y \geq 0\)}

To sketch the domain, we can plot the circle with radius 5 centered at the origin and shade the region above the x-axis. This represents all the valid input values for the function. The boundary of the domain is the circle, and the domain includes all points inside the circle and on the circle itself, but not outside the circle.

There are two main subtypes of quantitative data, which are discrete data and continuous data. Each subtype has different techniques for analysis.

1. Discrete data: This type of data represents whole numbers or counts that can only take specific values. Examples include the number of students in a class or the number of cars in a parking lot. Techniques used to analyze discrete data include:
  a. Frequency distribution: A summary of the number of times each value appears in the dataset.

 b. Measures of central tendency: Calculating the mean, median, and mode of the dataset to understand its central point.

 c. Measures of dispersion: Assessing the range, variance, and standard deviation to understand the spread of the data.

2. Continuous data: This type of data represents measurements that can take any value within a range, such as height, weight, or temperature. Techniques used to analyze continuous data include:

 a. Histogram: A graphical representation of the distribution of the data, using bars to represent the frequency of values within specific intervals.

  b. Probability density function: A mathematical function that describes the probability of a continuous random variable falling within a specific range.

  c. Regression analysis: A statistical method for analyzing the relationship between a dependent variable and one or more independent variables.

Answer:2&2/3

Step-by-step explanation:

The statement is true. If we take any two distinct prime numbers, and the number "1", these numbers will always be pairwise relatively prime.

Two numbers are said to be pairwise relatively prime if their greatest common divisor (GCD) is equal to 1. In this case, since we are considering distinct prime numbers, their GCD will always be 1 since prime numbers have no common factors other than 1 and themselves. Therefore, any two distinct prime numbers will be relatively prime.

Similarly, when we consider the number "1", it is relatively prime to any other number because its only divisor is 1. Hence, when "1" is paired with any prime number, the GCD will be 1.

In summary, whether we consider two distinct prime numbers or pair them with the number "1", the resulting numbers will always be pairwise relatively prime.
