Alaska occupies 17.22% of the surface area of the United States. Rounding to the nearest whole number, we get 17%. Hence, the answer is:17%

We are given that the surface area of the United States is 3.797 million square miles and the state of Alaska occupies 655,400 square miles. We need to determine what percentage of the surface area of the United States is occupied by Alaska using ratios.To find the percentage, we need to first find the ratio of Alaska's surface area to the surface area of the United States. We can do this by dividing the surface area of Alaska by the surface area of the United States. That is,655,400 / 3,797,000 = 0.1722We can express this ratio as a percentage by multiplying by 100. That is,0.1722 × 100 = 17.22%

Answer:c) 4/5

Step-by-step explanation:

y= mx+c, here, m is the slope.

In this case, m= 4/5, c= -3

We need to remember the quadratic function in it's standard form:

where a,b,c can be any real number.

For the point A) We can compare this equation to the equation that they give us in the question,since the term with the quatratic x is 5x^2 we conclude that a=5, since there is no a linear term x in the equation we conclude that b=0, and finally since the independent term is 1, we conclude that c=1.

For the point B) The graph opens up because a=5 that is a positive number.

For the point c) The vertex is (0,1) because -b/2a=-0/10=0 and when we replace it in the equation we will obtain that y=1

For the point D) The axis of symmetry is the y-axis because there are no quadratic terms in the equation that involves the variable y. the equation of the axis of symmetry is x=0

For the point E) in accordance with the procedure of point C) the y- intercept will be (0,1)

the graph of the equation is:

6.28 feet is the  circumference of a circle with a diameter of 2 feet

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The circumference of a circle is given by the formula:

Circumference=2πr

Where two times of r is equal to diameter

circumference =πd

The diameter is given as 2 feet, so we can substitute this value into the formula:

circumference = 3.14 x 2

Three point one four times of two

We get six point two eight

= 6.28 feet

Therefore, 6.28 feet is the  circumference of a circle with a diameter of 2 feet

Answer:

C)  I, III, IV, II

Step-by-step explanation:

Convert each number into a decimal:

\(\textsf{I.} \quad \dfrac{58}{67}=0.86567...\)

\(\textsf{II.} \quad 0.58\%=\dfrac{0.58}{100}=0.0058\)

\(\textsf{III.} \quad 58\%=\dfrac{58}{100}=0.58\)

\(\textsf{IV.} \quad 5.8\%=\dfrac{5.8}{100}=0.058\)

Comparing the tenths of all the numbers, 8 is the biggest tenth, so 58/67 is the largest number.

The next biggest tenth is 5, so 58% is the next largest number.

The two remaining numbers have zero tenths, so compare their hundredths. 5 is the largest hundredth, so 5.8% is the next largest number.  Therefore, 0.58% is the smallest number.

Therefore, the given set of numbers in order from greatest to least is:

This is further explained below.

Generally,  the equation for the expansion is  mathematically given as

(3 x-1)^4

Pascal's Triangle can be displayed as such:

1

1-1

1-2-1

1-3-3-1

1-4-6-4-1

The triangle can be used to calculate the coefficients of the expansion of (a+b)^n by taking the exponent n and adding 1 .

The coefficients will correspond with line n+1 of the triangle.

For (3 x-1)^4, n=4 so the coefficients of the expansion will correspond with line 5.

The expansion follows the rule

(a+b)^n=c_0 a^n b^0+c_1 a^{n-1} b^1+c_{n-1} a^1 b^{n-1}+c_n a^0 b^n

The values of the coefficients, from the triangle, are $-4-6-4-1.

\($1 a^4 b^0+4 a^3 b+6 a^2 b^2+4 a b^3+1 a^0 b^4$\)

Substitute the actual values of a 3 x and b-1 into the expression.

Answer: C. The classmate did not reverse the coordinates of (2, 1), so the inverse of s is wrong and it is not a function

The first two points in relation s are (3,1) and (2,1). Their coordinates swap to get (1,3) and (1,2) respectively which helps form the inverse relation.

We don't have a function with { (1,3), (1,2) } because the x coordinate repeats itself. Functions are only possible if any input x leads to exactly one output y.

Step-by-step explanation:

1 year insurance policy covering its equipment was purchased for 6,144. The date purchased was June 14 but it doesn't go into effect until June 16th, the amount paid for the month of June is approximately $252.75, and the amount paid for the entire year is approximately $6,144.

To calculate the amount paid for the month and the year, we need to consider the number of days covered by the insurance policy. Let's break it down step by step:

Step 1: Determine the number of days covered in June.

Since the policy doesn't go into effect until June 16th, there are 15 days remaining in June that will be covered by the insurance policy.

Step 2: Calculate the daily rate.

To find the daily rate, we divide the total cost of the insurance policy by the number of days in a year:

Daily rate = 6,144 / 365

Step 3: Calculate the amount paid for June.

The amount paid for June can be found by multiplying the daily rate by the number of days covered:

Amount paid for June = Daily rate * Number of days covered in June

Step 4: Calculate the amount paid for the year.

To calculate the amount paid for the year, we simply multiply the daily rate by 365 (the total number of days in a year):

Amount paid for the year = Daily rate * 365

Now let's perform the calculations:

Step 2: Daily rate

Daily rate = 6,144 / 365 ≈ 16.85 (rounded to two decimal places)

Step 3: Amount paid for June

Amount paid for June = 16.85 * 15 ≈ 252.75 (rounded to two decimal places)

Step 4: Amount paid for the year

Amount paid for the year = 16.85 * 365 ≈ 6,144 (rounded to two decimal places)

The net present value of the project is $0.15 million.

Net present value is the present value of after-tax cash flows from an investment less the amount invested.

hee, we have,

The first step is to determine the cash flow of the project.

Cash flow = (sales - cost - depreciation) × (1 - tax) + depreciation

Depreciation = (cost of the asset ) / useful life

Depreciation = $2.18 million / 3

Depreciation = 0.727 million

Cash flow = (1.645 -  0.61 - 0.727) x (1 - 0.21) + 0.727 = $0.97 million

Net present value = -2.18 million + 0.97 / 1.12 +  0.97 / 1.12² +  0.97 / 1.12³

Firstly, we will have to make a representation of the angle

We have this as follows;

As we can see, alpha added to theta is 180 degrees

Firstly, by the use of Pythagoras' theorem, we can get the value of r

r faces the right angle, and that makes it the hypotenuse

According to the theorem, the square of r, the hypotenuse equals the sum of the squares of the two other sides

Thus, we have it that;

From here, we can proceed to get the individual trigonometric ratios

a) Sine

This is the ratio of the opposite to the hypotenuse

On the second quadrant, the value of sine is positive

Thus, we have it that;

b) cosine

The cosine of an angle is the ratio of the adjacent to the hypotenuse

Mathematically, we know that;

We choose the negative value for the cosine since cosine is negative on the second quadrant

c) Tan

The tan of an angle is the ratio of the opposite to the adjacent

Also, by dividing the sine of an angle by the cosine of the same angle, we can get the tan of the angle

Thus, we have it that;

d) cosec theta

The cosec of an angle is the multiplicative inverse of the sine

Mathematically;

e) sec theta

The sec of an angle is the multiplicative inverse of the cosine of the angle

Thus, we have it that;

f) cot theta

The cot of an angle is the multiplicative angle of the tan

Thus, we have it that;

A, C, and D are not functions--they don't pass the vertical line test (there's not a single value y for each value of x).

Answer:

all real values of x where x < -1

The correct statement is all real values of x where x < -1.

Option A is the correct answer.

We have,

To determine the values for which the graph of the function

f(x) = (x - 3)(x + 1) is positive and decreasing, we need to analyze the behavior of the function.

Let's consider the factors individually:

(x - 3): This factor is positive for x > 3 and negative for x < 3.

(x + 1): This factor is positive for x > -1 and negative for x < -1.

To determine the overall sign of the function, we need to consider the signs of both factors together.

When both factors are positive or both factors are negative, the function is positive.

When the factors have opposite signs, the function is negative.

From the above analysis, we can conclude the following:

When x > 3, both factors are positive, so the function is positive.

When -1 < x < 3, the factor (x - 3) is negative, while the factor (x + 1) is positive. Therefore, the function is negative.

When x < -1, both factors are negative, so the function is positive again.

Since we are looking for values where the function is positive and decreasing, we can eliminate the options that include positive and increasing regions (such as x > 3).

Thus,

The correct statement is all real values of x where x < -1.
