The size of the the matrix B if a matrix A is 5x3 and the product AB is 5x7 is B =[3x7].

Two matrices can only be multiplied if the first matrix has the same number of columns as the second matrix has. If the first matrix has dimensions of a x b and the second matrix has dimensions of c x d, then b = c and their product will have dimensions of a x d.

Let A is a 3 x 5 matrix and B is a 5 x 7 matrix

We know that matrix multiplication of A and B is possible if

Number of columns of A = Number of rows of B

Since in the given problem

Number of columns of A = Number of rows of B = 5

So the product is possible

Now the product AB is a matrix of order 3 × 7

Now the order of the product AB is 3 × 7

If a 3 x 5 matrix is multiplied by a 5 x 7 matrix then their product is a matrix of order 3 × 7.

Answer:

  x = 3/2 ± i√2

Step-by-step explanation:

For quadratic ax² +bx +c = 0, the roots are given by the formula ...

  \(x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\)

When we put your equation into standard form:

  4x^2 -12x +17 = 0

we see the relevant formula values are ...

  a = 4, b = -12, c = 17

Then the roots are ...

  \(x=\dfrac{-(-12)\pm\sqrt{(-12)^2-4(4)(17)}}{2(4)}=\dfrac{12\pm\sqrt{-128}}{8}\\\\x=\dfrac{3\pm2\sqrt{2}i}{2}=\boxed{\dfrac{3}{2}\pm i\sqrt{2}}\)

It is proved that f(g(x)) = g(f(x)) =  x , So f(x) and g(x) are inverses of one other

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

We are given the function as;

f(x) = 5x + 2

g(x) = (x -2)/ 5

If two functions f(x)  and g(x) are inverses of each other, their compositions will equal

f(g(x)) = 5[ (x -2)/ 5] + 2

f(g(x)) = x - 2 + 2

f(g(x)) = x

Now,

g(f(x)) =  ((5x + 2) -2)/ 5

g(f(x)) =  (5x + 2 -2)/ 5

g(f(x)) =  x

it can be concluded that the population standard deviation is within or less than 12.

To construct a hypothesis test to determine whether the population standard deviation of σ≦12 should be rejected for Costco, we can use a chi-square test for variance.

Step 1: State the null and alternative hypotheses:
- Null hypothesis (H₀): σ ≤ 12
- Alternative hypothesis (H₁): σ > 12

Step 2: Determine the level of significance (α = 0.05) and degrees of freedom (df = n - 1 = 11 - 1 = 10).

Step 3: Calculate the test statistic:
- χ² = (n - 1) * (s² / σ²) = 10 * (11.3² / 12²) = 10 * 0.94 = 9.4

Step 4: Determine the critical value:
- The critical value at α = 0.05 with df = 10 is χ²ₐ = 18.307

Step 5: Compare the test statistic with the critical value:
- Since χ² = 9.4 < χ²ₐ = 18.307, we fail to reject the null hypothesis.

Step 6: Conclusion:
- Based on the given sample data, there is not enough evidence to reject the hypothesis that the population standard deviation of σ≤12 for Costco.

Therefore, it can be concluded that the population standard deviation is within or less than 12.

The answer is "183  yards"

Step-by-step explanation:

\(Drive \ 1= 180 \ yards \\\\Drive \ 2= 170 \ yards\\\\ Drive\ 3= 195 \ yards \\\\Drive \ 4= x \ \ yards \\\\\)

Using formula:

\(\to \text{average of number}=\frac{sum \ of \ number}{total\ number}\\\\\to 182 =\frac{180+170+195+x}{4}\\\\\to 4 \times 182 =545+x\\\\\to x= 728-545\\\\\to x=183\)

The number 320.5492492492... is rational and can be expressed as the fraction 1829/333.

To show that the number 320.5492492492... is rational, we can follow the same approach as before and express it as a sum of rational numbers.

Let x = 320.5492492492...

We can separate the integer part of x and the repeating decimal part:

x = 320 + 0.5492492492...

To express the repeating decimal part as a fraction, we can subtract a portion of it from the original number, like this:

1000x - 320000 = 549.2492492...

100000x - 32000000 = 549249.2492492...

Now we can subtract the first equation from the second equation:

99900x = 549249.2492492... - 549.2492492...

This simplifies to:

99900x = 548700

x = 548700/99900

Simplifying the fraction by dividing both numerator and denominator by their greatest common factor, we get:

x = 1829/333

Therefore, the number 320.5492492492... is rational and can be expressed as the fraction 1829/333.

Option D. m<A = 43, m<B = 55, a = 20

Step-by-step explanation:

1. Determination of angle B.

Angle C = 82

Opposite C (c) = 29

Opposite B (b) = 24

Angle B =?

Using Sine rule, we can obtain the value of angle B as follow:

b/Sine B= c/Sine C

24/Sine B = 29/Sine 82

Cross multiply

29 × Sine B = 24 × Sine 82

Divide both side by 29

Sine B = (24 × Sine 82) /29

Sine B = 0.8195

Take the inverse of Sine.

B = Sine¯¹ (0.8195)

B = 55

2. Determination of angle A.

Angle C = 82

Angle B = 55

Angle A =?

The value of angle A can be obtained as follow:

A + B + C = 180 (sum of angle in a triangle)

A + 55 + 82 = 180

A + 137 = 180

Collect like terms

A = 180 – 137

A = 43

3. Determination of side a (Opposite A)

Angle C = 82

Opposite C (c) = 29

Angle A = 43

Opposite A (a) =?

The value 'a' can be obtained as by using sine rule as illustrated below:

a/Sine A = c/Sine C

a/Sine 43 = 29/Sine 82

Cross multiply

a × Sine 82 = 29 × Sine 43

Divide both side by Sine 82

a = (29 × Sine 43) /Sine 82

a = 20

Therefore,

m<A = 43, m<B = 55, a = 20

Yes, the vector v is necessarily orthogonal to w if v is in the image of the symmetric matrix A and w is in the kernel of A. This is due to the fact that for any symmetric matrix A, the image (column space) and kernel (null space) are orthogonal subspaces. Since v is in the image of A and w is in the kernel of A, their dot product must be zero, indicating orthogonality.

The hiker's distance and bearing from their starting point are approximately 7.155 miles and 28.07°, respectively.

Given that two hikers travel 8 mi southeast and then 6 mi east, we are to find the hikers distance and bearing from their starting point at this time.Long ExplanationThe bearing of the hiker refers to the angle between the hiker's direction and North. So, let us assume that the hiker has initially moved at a direction East, as shown below:We are given that the hiker has traveled 8 miles to the southeast.

Therefore, from the diagram, the distance traveled in the East direction is 8 sin(45) miles, and the distance traveled in the South direction is 8 cos(45) miles. East = 8 sin(45) = 8/√2 = 4√2 miles South = 8 cos(45) = 8/√2 = 4√2 miles We are then told that the hiker travels 6 miles east, from the last position.

Answer:

a = -3

Step-by-step explanation:

Step 1:  Since we're told that 5 to the power of a = 1/125, we can use the following equation to solve for a:

5^a = 1/125

Step 2:  Take the log of both sides

log(5^a) = log(1/125)

Step 3:  According to the power rule of logs, we can bring a down and multiply it by log(5):

a * log(5) = log (1/125)

Step 4:  Divide both sides by log(5) to solve for a:

(a * log(5) = log(1/125)) / log(5)

a = -3

Optional 5:  We can check our answer by plugging in -3 for a and seeing if we get 1/125 when completing the operation:

5^-3 = 1/125

1/(5^3) = 1/125 (rule of exponents states that a negative exponent creates a fraction with 1 as the numerator and the base (5) and exponent (-3 becoming 3) as the denominator

1/125 = 1/125

The bisection method is a numerical method for finding the roots of a polynomial. This method starts by evaluating the polynomial at the mid-point of the interval.

The polynomial is evaluated at the interval's endpoints, and the half of the interval containing the root is chosen based on the sign of the evaluated results.If f(a) and f(b) have different signs, then there is a root between them. The midpoint of this interval is used to check the sign of f at the midpoint.

The half-interval that includes the root is chosen as the new interval. The midpoint of the new interval is used to determine whether the midpoint has the same sign as f(a) or f(b).

Here, we use the bisection method to estimate the root of the equation In(x - 1) + cos(x - 1) = 0, with absolute error less than 10^(-12), in the interval [1, 2]. Let's start by defining the function to be evaluated as `f(x) = ln(x - 1) + cos(x - 1)`.

Now, Let's define `a = 1` and `b = 2`, which is the interval containing the root.To apply the bisection method, we compute the midpoint of the interval \(`c = (a + b) / 2`, which is equal to `c = (1 + 2) / 2 = 1.5`\).Then we calculate `f(c)` as follows:f(c) = f(1.5) = ln(1.5 - 1) + cos(1.5 - 1) = 0.25597837Since `f(a)` and `f(c)` have opposite signs,

we conclude that the root lies in the interval `[1, c]`.Thus, the new interval is `[1, c] = [1, 1.5]`, and we will continue the bisection method by computing the midpoint `d = (1 + 1.5) / 2 = 1.25`.
