Answer:

f(x)=x^3-3x^2+25x-75

Step-by-step explanation:

Solve for x:

x^3 - 3 x^2 + 25 x - 75 = 0

The left hand side factors into a product with two terms:

(x - 3) (x^2 + 25) = 0

Split into two equations:

x - 3 = 0 or x^2 + 25 = 0

Add 3 to both sides:

x = 3 or x^2 + 25 = 0

Subtract 25 from both sides:

x = 3 or x^2 = -25

Take the square root of both sides:

Answer:  x = 3 or x = 5 i or x = -5 i

Answer: So the sum of all of the measures of the interior angles of a 16-sided polygon is 2520 degrees.

The sum of the interior angles of a 16-sided polygon is 2520 degrees.

The sum of the interior angles of a 16-sided polygon, or hexadecagon, is 2520 degrees, which can be calculated using the formula (n-2) x 180 degrees.

The sum of the interior angles of any polygon can be found using the formula (n-2)  imes 180 degrees, where n is the number of sides of the polygon. A 16-sided polygon is known as a hexadecagon. Using the formula, we have:

Sum of interior angles = (16-2)  imes 180 degrees

Sum of interior angles = 14  imes 180 degrees

Sum of interior angles = 2520 degrees

Therefore, the sum of the interior angles of a 16-sided polygon is 2520 degrees.

Answer:

x = -7 and x = 2

Step-by-step explanation:

Look for the points on the graph where if you draw a horizontal line at y=1, you will intersect the curve.

By observation, we can see that this happens at x = -7 and x = 2

x = -7 and x = 2

Here in the diagram, we can see that, a curve is present & 6 co-ordinates on that curve are given.

We have to find the values of x correspond with f(x) = 1

f(x) = 1 means y = 1

So, if we draw a horizontal line at y = 1, which is parallel to x-axis.

Then, we can able to observe the points which are on the line y = 1.

So, the points on line y = 1 are (-7, 1) & (2, 1).

Hence, we can say that, input values that correspond with f(x) = 1 are x= -7 & x = 2.

Move 5r to the left hand side . Positive 5r changes to negative 5r

7r-5r+2= 5r-5r-20

2r+2=- 20

2r+2-2= -20-2

Move positive 2 to the right hand side. Changes to negative -2

2r+2-2= -20-2

2r= -22

Divide by 2 for 2r and -22

2r/2= -22/2

r= -11

Answer is r= -11

Answer:

r = (-11)

Step-by-step explanation:

7r + 2 = 5(r – 4) ​

7r + 2 = 5r – 4 * 5

7r + 2 = 5r – 20

7r - 5r = -20 - 2

3 to the 2nd power plus 3 to the 3rd power does not equal 3 to the 5th power. In actuality, 3^2 + 3^3 = 36, while 3^5 = 243.

No, 3 to the 2nd power plus 3 to the 3rd power does not equal 3 to the 5th power. This is a common misconception when dealing with exponents. To clear this up, let's look at what these expressions actually mean:

3 to the 2nd power (3^2) = 3*3 = 9

3 to the 3rd power (3^3) = 3*3*3 = 27

So, 3^2 + 3^3 = 9 + 27 = 36

However, 3 to the 5th power (3^5) = 3*3*3*3*3 = 243

So, as you can see, 36 does not equal 243.

Answer:

Option A (Causation cannot be proven because lower test scores can occur for other reasons, such as not studying or poor attendance).

Step-by-step explanation:

Correlation is a concept which explains a linear relationship between two variables. The correlation constant lies between -1 and 1. 0 lies in the center of the interval. A negative correlation means an inverse relationship, and a positive correlation means a direct relationship. 0 technically means no linear relation between the variables. Further the correlation constant lies from 0, more the strength of the relationship. It is important to note that correlation shows a relationship between the two variables but it cannot determine the causation i.e. it cannot be concluded that one variable caused the other variable to occur. Even though having a strong correlation does not mean causal relationship. Therefore, correlation does not prove causation. This is because there are several other lurking and unobserved variables which affect the observed variables. The former class of variables are not accounted for in the correlation. Therefore, the exact magnitude of the causal relationship cannot be determined. Therefore, Option A is the correct choice!!!

Answer: 50 degrees.

Step-by-step explanation:

To find the measure of the angle Q, you need to follow these steps:

- Knowing that:

[tex]-980= -(1,360)cos(Q)[/tex]

You can divide both sides of the equation by -1,360:

[tex]\frac{-980}{-1,360}=\frac{-1,360cos(Q)}{-1,360}\\\\\frac{49}{68}=cos(Q)[/tex]

- Finally, using  the inverse function of the cosine, Arccosine, we get:

These are the terms of an arithmetic sequence

The n th term ( explicit rule ) for an arithmetic sequence is

where a₁ is the first term and d the common difference

d = 9 - 2 = 16 - 9 = 23 - 16 = 30 - 23 = 7 and a₁ = 2, hence

[tex]a_{n}[/tex] = 2 + 7(n - 1) = 2 + 7n - 7 = 7n - 5

The explicit rule for the sequence 2,9,16,23,30... is 7n - 5

Answer:

2160

Step-by-step explanation:

36*20=720      720*3=2160

To find the number of square inches of paper needed, multiply the length and width of each drawer to get the area, and then multiply that area by 3.

To find the number of square inches of paper needed, we need to find the area of the bottom of each drawer and then add them together. The area of a rectangle is found by multiplying its length by its width. So, for each drawer, we multiply 36 inches by 20 inches to get an area of 720 square inches.

Since there are 3 drawers, we need to multiply the area of one drawer by 3. So, the total number of square inches of paper needed is 720 square inches times 3, which equals 2160 square inches.

Therefore, the correct answer is D) 2160.
