Hello There!
First, our formula for finding the volume of a cylinder is Pi*radius^2*height
Now, let'd get into solving for the volume. First, we need to find the radius so in this problem, we are given the diameter so to find the radius, we just divid the diameter by 2. Once we divide, our radius comes out to 6.5.
Next, in our formula it says we have to square our radius so we would multiply 6.5 by 6.5 to get a product of 42.25.
Lastly, we need to multiply 42.25 by our height which is our last step in our formula. Once we multiply 42.25 by the height of the cylinder which is 11, we get a product of 464.75.
464.75 rounded to the nearest tenth is 464.8

Find an equation of the line perpendicular to the graph of 28x-7y=9 that passes through the point at (4,1)
Answers
Answer:
Step-by-step explanation:
For this case we have by definition, if two lines are perpendicular then the product of their slopes is -1.
[tex]m_ {1} * m_ {2} = - 1[/tex]
We have the following equation:
[tex]28x-7y = 9[/tex]
Rewriting we have:
[tex]28x-9 = 7y\\y = \frac {28x-9} {7}\\y = 4x- \frac {9} {7}[/tex]
The slope of this line is 4.
We found [tex]m_ {2}:[/tex]
[tex]m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {4} = - \frac {1} {4}[/tex]
The new line is of the form:
[tex]y = - \frac {1} {4} x + b[/tex]
We substitute the given point to find the cut point "b":
[tex]1 = - \frac {1} {4} (4) + b\\1 = -1 + b\\b = 2[/tex]
Finally, the equation is:
[tex]y = - \frac {1} {4} x + 2[/tex]
Answer:
[tex]y = - \frac {1} {4} x + 2[/tex]
Blake brought 2 magazines for $4.95 each. If the sales tax was 6.75%, what was the total amount that he paid for the magazines?
Answers
Answer:
$10.57
Step-by-step explanation:
Blake brought 2 magazines for = $4.95 each
Cost of 2 magazines = 4.95 × 2 = $9.90
Sales tax rate = 6.75%
Total amount that he paid for the magazines = 9.90 + (6.75% × 9.90)
= 9.90 + (0.0675 × 9.90)
= 9.90 + 0.66825
= $10.56825 ≈ $10.57
He paid $10.57 for the magazines.

4x – 3y = 17
y-intercept:
2-intercept:
Answers
Answer:
y-intercept = -17/3x-intercept = 17/4Step-by-step explanation:
4x - 3y = 17
y-intercept is for x = 0.
x-intercept is for y = 0.
y-intercept:
put x = 0 to the equation
4(0) - 3y = 17
0 - 3y = 17
-3y = 17 divide both sides by (-3)
y = - 17/3
x-intercept:
put y = 0 to the equation
4x - 3(0) = 17
4x - 0 = 17
4x = 17 divide both sides by 4
x = 17/4

Answers
Answer:
B
Step-by-step explanation:
Given
x² - 2x + 26 = 0 ← in standard form : ax² + bx + c = 0 : a ≠ 0
with a = 1, b = - 2, c = 26
Use the quadratic formula to solve for x
x = ( - (- 2) ± [tex]\sqrt{(-2)^2-(4(1)(26)}[/tex] ) / 2
= ( 2 ± [tex]\sqrt{4-104}[/tex] ) / 2
= ( 2 ± [tex]\sqrt{-100}[/tex] ) / 2
= ( 2 ± 10i ) / 2
= 1 ± 5i
Solutions are x = 1 + 5i or x = 1 - 5i → B
The equation x² - 2x + 26 = 0 has no real solutions. Thus, none of the given options are correct.
Explanation:To solve the equation x² - 2x + 26 = 0, we can use the quadratic formula.
For an equation of the form ax² + bx + c = 0, the quadratic formula is given by:
x = (-b ± √(b² - 4ac)) / (2a)
By substituting the values a = 1, b = -2, and c = 26 into the formula, we get:
x = (-(-2) ± √((-2)² - 4(1)(26))) / (2(1))
Simplifying further:
x = (2 ± √(-92)) / 2
Since taking the square root of a negative number results in a complex solution, we can conclude that there are no real solutions to the equation x² - 2x + 26 = 0.
Which of the following is a 3rd degree polynomial with roots i and 2?
Answers
Answer:
D
Step-by-step explanation:
Given the roots of a polynomial, say x = a, x = b, x = c, then
(x - a), (x - b) and (x - c) are the factors and the polynomial is the product of the factors.
Note complex roots occur in conjugate pairs, thus
x = i is a root ⇒ x = - i is also a root
given roots x = 2, x = i, x = - i are roots, then
(x - 2), (x - i) and (x + i) are the factors and
f(x) = (x - 2)(x - i)(x + i)
= (x - 2)(x² - i²)
= (x - 2)(x² + 1)
= x³ + x - 2x² - 2
= x³ - 2x² + x - 2 → D
The 3rd degree polynomial with roots i and 2 is P(x) = x^3 - 2x^2 + x - 2, which is found by multiplying the factors (x - i), (x + i), and (x - 2).
Explanation:A 3rd degree polynomial with roots i and 2 must also have the complex conjugate of i, which is -i, as a root because the coefficients of the polynomial are real numbers. Thus, the polynomial will have three roots: i, -i, and 2. To find the polynomial, we can use the fact that a polynomial equation is the product of its factors. Therefore, we start by writing down the factors that correspond to each root:
(x - i)(x + i)(x - 2)Multiplying these factors together will give us the desired 3rd degree polynomial:
Multiply the factors (x - i) and (x + i), which are conjugates, to get x^2 + 1 because (i)(-i) = -i^2 = 1.Now, multiply the quadratic polynomial x^2 + 1 by (x - 2) to get the 3rd degree polynomial.The full expansion gives us the polynomial P(x) = x^3 - 2x^2 + x - 2.

Range is subtracting the biggest number in the data set by the smallest number
Hope this helped!
~Just a girl in love with Shawn Mendes
Final answer:
The mean is the average of a data set, the median is the middle value, the mode is the most frequent value, and the range is the difference between the highest and lowest values. The median is preferred in skewed distributions.
Explanation:
Mean, Median, Mode, and Range in Mathematics
The mean is the average of a data set, calculated by adding up all the values and dividing the total by the number of values. The median is the middle value when the data set is ordered from least to greatest, or the average of two middle values if there is an even number of values in the data set. The mode is the value that appears most frequently in a data set. The range is the difference between the highest and lowest values in the data set. Each of these measures provides different information about the distribution of the data and can be affected by outliers or the overall shape of the data distribution.
For example, consider the data set: 4, 5, 6, 6, 7, 8, 9. The mean is (4+5+6+6+7+8+9)/7 = 6.43, the median is 6, and the mode is 6 (since it appears the most). The range is 9-4 = 5.
In cases where data sets include outliers or are skewed, the mean may not be representative of the data's center. For instance, if a data set is 4, 5, 6, 6, 7, 8, 100, the mean is significantly influenced by the outlier (100), while the median remains a better indicator of the center. In such distributions, the median is often preferred over the mean.

classify the triangle by its sides
a(3,-3), b(1,4), c(-1,-1)
Answers
Answer:
The triangle is scalene Δ
Step-by-step explanation:
* Lets revise the types of the triangle according to its sides
- Equilateral triangle: its three sides are equal in lengths
- Isosceles triangle: two sides are equal in lengths
- Scalene triangle: its three sides have different lengths
- The length of a segment basses through two points (x1 , y1) and
(x2 , y2) is √[(x2 - x1)² + (y2 - y1)²]
* Lets solve the problem
∵ abc is a triangle with vertices a (3 , -3) , b (1 , 4) , c (-1 , -1)
- To classify the triangle by its side find the lengths of the 3 sides
∵ a = (3 , -3) and b = (1 , 4)
∴ ab = √[(1 - 3)² + (4 - -3)²] = √[(-2)² + (7)²] = √[4 + 49] = √53
∵ b = (1 , 4) and c = (-1 , -1)
∴ bc = √[(-1 - 1)² + (-1 - 4)²] = √[(-2)² + (-5)²] = √[4 + 25] = √29
∵ c = (-1 , -1) , a = (3 , -3)
∴ ca = √[(3 - -1)² + (-3 - -1)²] = √[(4)² + (-2)²] = √[16 + 4] = √20
∵ The lengths of the three sides of the triangle are √53 , √29 , √20
∴ The lengths of the three sides are different
∴ The triangle is scalene Δ

Solving for 'x'we have:
4x = -46 + 6 ⇒ 4x = -40 ⇒ x = 10.
Then, the solution is: x=10
Answer:
4x - 6 = -46
x = -10
Step-by-step explanation:
We are given the following sentence equation into a mathematical equation and then solve it to find each number:
The difference between four times a number and six is –46.
Translating it in chunks to make it easier:
1) The difference between ---> means there is a subtraction sign
2) four times a number ---> assuming x to be the number ---> 4x
3) and six ---> 6
4) is -46 ---> = -46
Combining these to get:
[tex]4x - 6 = -46[/tex]
[tex]4x = -46 + 6[/tex]
[tex]4x = -40[/tex]
[tex]x=\frac{-40}{4}[/tex]
