The smallest number a such that A + BB is regular for all B > a can be determined by finding the eigenvalues of the matrix A. The value of a will be greater than or equal to the largest eigenvalue of A.

A matrix A is regular if it is non-singular, meaning it has a non-zero determinant. We can consider the expression A + BB as a sum of two matrices. To ensure A + BB is regular for all B > a, we need to find the smallest value of a such that A + BB remains non-singular. One way to check for singularity is by examining the eigenvalues of the matrix A. If the eigenvalues of A are all positive, it means that A is positive definite and A + BB will remain non-singular for all B. In this case, the smallest number a can be taken as zero. However, if A has negative eigenvalues, we need to choose a value of a greater than or equal to the absolute value of the largest eigenvalue of A. This ensures that A + BB remains non-singular for all B > a.

Step-by-step explanation:

3x+2y-5y=0

3x-3y=0

x=y+10

3(y+10)-3y=0  ==> plugin y+10 for x

3*y + 3*10 - 3y = 0 ==> distribute 3 to y and 10

3y + 30 - 3y = 0

3y - 3y + 30 = 0

30 \(\neq\) 0    

3(y+10)-3y \(\neq\) 0

3(y+10)-3y \(\neq\) 3x-3y  ==> 3x-3y=0

Hence, there are no solutions.

One period of solutions is:

x ≈ 0.729 + kπ radians ≈ 41.8 + 180k degrees

x ≈ 1.148 + kπ radians ≈ 65.8 + 180k degrees

x ≈ 2.576 + kπ radians ≈ 147.6 + 180k degrees

We can write the equation as:

tan(x) = 20 - 7cos(x)

Since both tan(x) and cos(x) have a period of π, we only need to find solutions in the interval [0, π]. We can use a graphing calculator or a table of values to find approximate solutions. Here are a few solutions:

x ≈ 0.729 radians ≈ 41.8 degrees

x ≈ 1.148 radians ≈ 65.8 degrees

x ≈ 2.576 radians ≈ 147.6 degrees

To find one period of solutions, we can add or subtract multiples of the period π. Since the tangent function has a vertical asymptote every π radians, we need to exclude any solutions that make the denominator of the equation equal to zero.

Therefore, one period of solutions is:

x ≈ 0.729 + kπ radians ≈ 41.8 + 180k degrees

x ≈ 1.148 + kπ radians ≈ 65.8 + 180k degrees

x ≈ 2.576 + kπ radians ≈ 147.6 + 180k degrees

The number of combination or ways she can pick 4 is , 12,650 ways.

In mathematics, a permutation for a set of value can be defined as  the arrangement of its members into a sequential order, or in the case if  set is already in a proper ordered , the rearrangement of the elements.

If we have to find the number of ways to do something then we can use the concept of permutation.

If n is no of total elements and r is no of selection , then permutation is :

\(np_{r} = \frac{n !}{(n-r)!}\)

Whereas, a combination is use to define the number of ways to select something or select particular set of values from the total set.

If n is no of total elements and r is no of selection , then combination is :

\(nC_r = \frac{n!}{r! . (n-r)!}\)

In the given question:

n = 25 and r =4

thus, no of ways = \(25C_4 = \frac{25!}{4! . 21!}\)

=> no of ways = \(\frac{25 . 24 . 23 . 22}{4!}\) = 12,650

Hence, The number of combination or ways she can pick 4 is , 12,650 ways.

Answer:

$1.030 ($1.03 rounded.)

Step-by-step explanation:

First, we need to start of making an equation.

$2.36 + x = 6.48.

We will use x as the variable for the amount of each bottle of juice, because it is unknown.

Then, we must put the variable on one side of the equation. To do this, we must subtract $2.36 from $6.48; and $2.36 - $2.36.

We get the result that x = $4.12. However, only 1 pack is $4.12, and we must find the cost of 4 juice bottles. Therefor, we divide 4.12 by 4.

If Lillian bought a bag of apples for $2.36 and a 4-pack of juice bottles. The total cost before tax was $6.48 then each juice bottle costs $1.03.

Let's denote the cost of each juice bottle as "x".

Since Lillian bought a 4-pack of juice bottles, the total cost of the juice is 4x.

Given that the total cost before tax was $6.48, we can set up an equation:

Cost of apples + Cost of juice = Total cost

$2.36 + 4x = $6.48

Now, solve for "x":

4x = $6.48 - $2.36

4x = $4.12

x = $4.12 / 4

x = $1.03

Hence, Each bottle of juice costs $1.03.

A leaf plot, also known as a stem-and-leaf plot, is a way of displaying numerical data by separating each value into a "stem" and "leaf" and organizing them in a table for easy analysis.

To find the value of the 18th percentile for this data set, we need to first determine how many scores fall below that percentile.

Since there are 31 scores in total, the 18th percentile would correspond to the score at the 0.18(31) = 5.58th position when the scores are listed in ascending order. However, since we are given a stem-and-leaf plot rather than the raw data, we need to estimate the position of the 18th percentile based on the plot.

Looking at the plot, we can see that there are a total of 31 scores, with 12 of them falling in the range from 120 to 139 (inclusive) and 9 of them falling in the range from 140 to 159 (inclusive). This means that the 18th percentile must be somewhere in the first group of scores.

To estimate the exact position, we can use the fact that the 12 scores in the first group represent 12/31 = 0.3871 (rounded to 4 decimal places) of the total number of scores. To find the position of the 18th percentile within that group, we can multiply that fraction by the number of scores in that group:

0.3871 x 12 = 4.6452 (rounded to 4 decimal places)

So the 18th percentile falls somewhere between the 4th and 5th scores in the first group. Looking at the stem-and-leaf plot, we can see that the 4th score is 127 and the 5th score is 133.

Therefore, the value of the 18th percentile for this data set is between 127 and 133.5 (since we know it falls between the 4th and 5th scores in the first group, and there is a gap of 0.5 between adjacent scores).

The answer choices given are 152, 133, 127, and 133.5. Of these, the only one that falls within the range we just determined is 133. Therefore, the answer is:

Step-by-step explanation:

y = - 2x + 3 ← is in slope- intercept form

with slope m = - 2

The second derivative of the equation \( \sin(x^2) + \cos(y^2) = 1 \) with respect to \( x \) is \( \frac{{d^2y}}{{dx^2}} \).

To find the second derivative of the given equation with respect to \( x \), we need to differentiate both sides of the equation implicitly with respect to \( x \).

Differentiating the equation \( \sin(x^2) + \cos(y^2) = 1 \) with respect to \( x \) using the chain rule, we get:

\( 2x \cos(x^2) + (-2y) \sin(y^2) \cdot \frac{{dy}}{{dx}} = 0 \)

Rearranging the equation and isolating \( \frac{{dy}}{{dx}} \), we have:

\( \frac{{dy}}{{dx}} = \frac{{2x \cos(x^2)}}{{-2y \sin(y^2)}} \)

To find the second derivative, we differentiate \( \frac{{dy}}{{dx}} \) with respect to \( x \) using the quotient rule:

\( \frac{{d^2y}}{{dx^2}} = \frac{{(-2y \sin(y^2)) \cdot (2 \cos(x^2)) - (2x \cos(x^2)) \cdot (-2 \sin(y^2) \cdot \frac{{dy}}{{dx}})}}{{(-2y \sin(y^2))^2}} \)

Simplifying the expression, we can cancel out some terms:

\( \frac{{d^2y}}{{dx^2}} = \frac{{4y \sin(y^2) \cos(x^2) + 4x \cos(x^2) \sin(y^2) \cdot \frac{{dy}}{{dx}}}}{{4y^2 \sin^2(y^2)}} \)

Finally, substituting \( \frac{{dy}}{{dx}} = \frac{{2x \cos(x^2)}}{{-2y \sin(y^2)}} \) into the equation, we can simplify further:

\( \frac{{d^2y}}{{dx^2}} = \frac{{4y \sin(y^2) \cos(x^2) + 4x \cos(x^2) \sin(y^2) \cdot \frac{{2x \cos(x^2)}}{{-2y \sin(y^2)}}}}{{4y^2 \sin^2(y^2)}} \)

\( \frac{{d^2y}}{{dx^2}} = \frac{{2x^2 \cos^2(x^2) - 2y^2 \sin^2(y^2)}}{{y^3 \sin^3(y^2)}} \)

Hence, the second derivative of the given equation with respect to \( x \) is \( \frac{{2x^2 \cos^2(x^2) - 2y^2 \sin^2(y^2)}}{{y^3 \sin^3(y^2)}} \).
