Can a prime number be a multiple of 11?
Answers
Multiple of 11 cant be prime number.
What are prime numbers?Prime numbers are those that are bigger than 1. Only the number itself and factor 1 are present. This indicates that no number other than 1 and the number itself may be used to divide these numbers without leaving a residue.
Now that multiples of 11 are being questioned, such as 22, 33, and 44, can they be prime numbers?
We know that prime numbers are those that can only be divided by themselves and by one , but since these multiples of 11 are all divisible by 11, they cannot be prime numbers.
The multiple of 11 cannot thus be a prime number.

What is B^2+8b+7??
Can someone explain it step by step please?
Answers
Step-by-step explanation:
B^2+8b+7 is a quadratic expression. It can be factored as (b+7)(b+1).
To factor a quadratic expression, you can use the following steps:
1. Find two numbers that add up to the coefficient of the middle term (8) and multiply to the constant term (7).
2. Write the quadratic expression as a product of two binomials, with the two numbers you found in step 1 as the coefficients of the terms in each binomial.
In this case, the two numbers that add up to 8 and multiply to 7 are 7 and 1. So, we can factor B^2+8b+7 as follows:
(b+7)(b+1)
This means that B^2+8b+7 is equal to the product of (b+7) and (b+1).
Here is a step-by-step explanation of how to factor B^2+8b+7:
1. The coefficient of the middle term is 8.
2. The constant term is 7.
3. The two numbers that add up to 8 and multiply to 7 are 7 and 1.
4. Therefore, B^2+8b+7 can be factored as (b+7)(b+1).
To solve it, you can use the quadratic formula, which is:
x = (-b ± √(b^2 - 4ac)) / 2a
In this case, a = 1, b = 8, and c = 7.
So, substituting the values, we get:
x = (-8 ± √(8^2 - 4(1)(7))) / 2(1)
x = (-8 ± √(64 - 28)) / 2
x = (-8 ± √36) / 2
x = (-8 ± 6) / 2
x = -1 or -7
Therefore, B^2+8b+7 is equal to -1 or -7.
f(n+1)=f(n)-5. If f(1)=100, what is f(6)
Answers
Answer:
75
Step-by-step explanation:
Given:
f(1) = 100
f(n+1) = f(n) - 5
Solve for:
f(6)
Solution:
f(1) = 100
f(2) = f(1) - 5 = 100 - 5 = 100 - 1 x 5 = f(1) - 1 x 5
f(3) = f(2) - 5 = 100 - 5 - 5 = 100 - 2 x 5 = f(1) - 2 x 5
...
f(n) = f(n - 1) - 5 = 100 - (n-1) x 5 = f(1) - (n-1) x 5
=> f(6) = f(1) - (6-1) x 5 = 100 - 5 x 5 = 100 - 25 = 75

The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equations can be used to solve for y, the length of the room? Select three options. y(y + 5) = 750 y2 – 5y = 750 750 – y(y – 5) = 0 y(y – 5) + 750 = 0 (y + 25)(y – 30) = 0
Answers
The equations can be used to solve for y, the length of the room follows:
B. y² – 5y = 750, C. 750 – y(y – 5) = 0 and E. (y + 25)(y – 30) = 0
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
As per the question, we have
length L = y
width W = y - 5
Since the area of a rectangular room is 750 square feet.
So L × W = 750
y(y - 5) = 750
y² – 5y = 750 ....(i)
This can be also written as:
750 – y(y – 5) = 0 ....(ii)
Factorizing the equation (i), we get
(y + 25)(y – 30) = 0
Thus, the correct answer would be options (B), (C), and (E).

write the expression in algebraic form. [hint: sketch a right triangle, as demonstrated in example 3.] tan(arcsec(x/3))
Answers
The expression tan(arcsec(x/3)) can be written \(1/3 \sqrt{x^2-9}\) in algebraic form.
The inverse secant function, or arcsecant, is defined as the inverse of the secant function, which is the ratio of the length of the hypotenuse of a right triangle to the length of the adjacent side. Given x/3 as the length of the adjacent side, arcsec(x/3) is the measure of the angle that has a secant equal to x/3.
The tangent function is the ratio of the length of the opposite side of a right triangle to the length of the adjacent side. By substituting arcsec(x/3) as the measure of the angle in a right triangle, we can use the tangent function to find the ratio of the lengths of the opposite and adjacent sides, which is equal to \(1/3 \sqrt{x^2-9}\).

The value in the data set varies from 12 by an Average of 4.
The mean of the data set is 12 and the mean absolute deviation is 4.
Option 1: Each value in the data set varies from 12 by exactly 4.
This statement cannot be concluded based on the given information. The mean absolute deviation measures the average distance between each data point and the mean. It does not imply that each value varies by exactly 4 from the mean.
Option 2: Each value in the data set varies from 12 by an average of 4.
This statement is true. The mean absolute deviation of 4 indicates that, on average, each data point deviates from the mean by 4 units. It does not necessarily mean that each value varies by exactly 4, but the average deviation is indeed 4.
Option 3: No values in the data set are less than 8 or greater than 16.
This statement cannot be determined based on the given information. The mean and mean absolute deviation do not provide information about the specific values in the data set. It is possible for some values to be less than 8 or greater than 16 while still maintaining a mean of 12 and a mean absolute deviation of 4.

Find the equation of the tangent line to the following curve
at the indicated point.
Answers
The equation of the tangent line at the point (108, 6) on the curve y² = x²/(xy - 324) is: y = 6
How to find the equation of the tangent?
The equation is given as:
y² = x²/(xy - 324) at (108, 6)
Differentiating implicitly with respect to x gives:
2y(dy/dx) = (2x(xy - 324) - x²(y - 324)(dy/dx)) / (xy - 324)²
Simplifying further using power rule and chain rule gives us:
\(\frac{dy}{dx} = \frac{x^{2}y - 648x }{2y(-324 + xy) +x^{3} }\)
We can find the slope by plugging in x = 108 and y = 6 to get
\(\frac{dy}{dx} = \frac{(108^{2}*6) - 648(108) }{2(6)(-324 + (108*6)) + 108^{3} }\)
dy/dx = 0
To find the equation of the tangent line, we use the point-slope form:
y - y₁ = m(x - x₁),
where:
(x₁, y₁) is the given point (108, 6) and m is the slope.
Substituting the values, we have:
y - 6 = 0(x - 108)
y = 6
This is the equation of the tangent line at the point (108, 6) on the curve y² = x²/(xy - 324).

The correct number line that displays the solution `x ≥ 3` would be:

-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
●------------------------------------------------>
The solution `x ≥ 3` is an inequality that means x is greater than or equal to 3. To graph this inequality on the number line, we mark the point representing the value 3 with a closed circle on the number line and draw an arrow pointing to the right to indicate that all values greater than or equal to 3 satisfy the inequality.
The closed circle at 3 indicates that 3 is included in the solution set, and the arrow to the right indicates that all values greater than 3 also satisfy the inequality. Therefore, any value of x that is equal to or greater than 3 would be considered a solution to the inequality `x ≥ 3`.
It is important to note that if the inequality was `x > 3` (without the equal sign), the closed circle at 3 would be changed to an open circle, indicating that 3 is not included in the solution set, and only values greater than 3 would be considered solutions. In conclusion, the number line provided above correctly displays the solution `x ≥ 3`.
