UT The dimension of row space equals the dimension of column space c. If rank of A is smaller than the rank of A's augmented matrix, there is no solution for the linear system d. if rank of A equals the rank of A's augmented matrix, there is unique solution for the linear system . e. None of above

Answers

Answer 1

In this question about matrices, we know that If m equals n and the rank of A is n, A is invertible,  If the rank of A is smaller than the rank of A's augmented matrix, there is no solution for the linear system, and if the rank of A equals the rank of A's augmented matrix, there is a unique solution for the linear system. So, options A, C, and D are the correct answers.

The Number of independent rows determines a matrix's rank.

A square matrix has "full rank" and is non-singular when its rank equals the number of rows, at which point it has an inverse.

So, statement "A" is right.

Dimension of row space and column space may not be equal even if the matrix is square.

So, Statement "B" is incorrect.

For "No solution", the condition is that the Rank of the matrix is lesser than the augmented matrix.

So, the statement "C" is correct.

For the "Unique solution", the condition is that the Rank of the matrix is equal to the augmented matrix.

So, the statement "D" is correct.

So, we can check option B as the incorrect option.

Emily went to the store and bought five packages of cookies and 1 gallon of milk and spent $17 Emma went to the same store and bought 10 packages of cookies and 3 gallons of milk and spent $36 how much does each package of cookies cost 

Answers

Answer:

Let's use a system of equations to solve this problem.

Let c be the cost of one package of cookies. Then we can write two equations based on the given information:

5c + 1m = 17 (where m is the cost of one gallon of milk)

10c + 3m = 36

We want to solve for c, so let's eliminate m by multiplying the first equation by 3 and subtracting it from the second equation:

10c + 3m = 36

-(15c + 3m = 51)

-5c = -15

Simplifying, we get:

c = 3

Therefore, each package of cookies costs $3.

what is the best estimate for the amount of cost a when there is expected to be 8,570 units?

Answers

The best estimate for the amount of cost A when there is expected to be 8,570 units would depend on the cost per unit of A.

Without knowing the cost per unit, it is not possible to accurately estimate the total cost of A for 8,570 units.
To find the total cost of A for 8,570 units, you would multiply the cost per unit of A by the number of units (8,570). For example, if the cost per unit of A is $2, then the total cost of A for 8,570 units would be $2 x 8,570 = $17,140.
Therefore, without knowing the cost per unit of A, it is not possible to provide the best estimate for the amount of cost A when there is expected to be 8,570 units.

if N = 7^5* 3^8 *5^4 the sum of divisiors of N will be

Answers

N has a total number of divisors of 22,953,195,865,728.

To find the sum of divisors of N, we need to use the formula:

Sum of divisors = (p⁰ + p¹ + p² + ... + p^a) x (q⁰+ q¹ + q² + ... + q^b) x (r⁰ + r¹ + r² + ... + r^c) x ...

Where p, q, r, etc. are the prime factors of N, and a, b, c, etc. are the exponents of these prime factors.

Using this formula, we can find the sum of divisors of N as:

Sum of divisors = (1 + 7 + 7² + 7³ + 7⁴ + 7⁵) x (1 + 3 + 3² + ... + 3⁸) x (1 + 5 + 5² + 5³ + 5⁴)

Simplifying each of the geometric series within the parentheses, we get:

Sum of divisors = (1 - 7⁶)/(1 - 7) x (1 - 3⁹)/(1 - 3) x (1 - 5⁵)/(1 - 5)

Evaluating each of these fractions, we get:

Sum of divisors = (11764808) x (19682) x (78126)

Multiplying these values together, we get:

Sum of divisors = 22,953,195,865,728

What is the relationship between speed, distance and time?

The relationship between speed, distance, and time is given by the formula:

distance = speed x time

This formula states that the distance covered by an object is equal to the product of its speed and the time it travels. Alternatively, we can say that:

speed = distance / time

This formula gives the speed of an object based on the distance it covers and the time it takes. Finally, we can also rearrange the formula to solve for time:

time = distance / speed

This formula gives the time it takes for an object to travel a certain distance at a given speed.


Given by the question:
Adriana drove for 8 minutes at 46 meters per minute, so the total distance she drove is:

distance = time x speed = 8 minutes x 46 meters per minute = 368 meters

Since it was raining for one-quarter of the time, the time Adriana spent driving in the rain is:

time in rain = 8 minutes x (1/4) = 2 minutes

To find the distance she drove in the rain, we can use the formula:

distance = time x speed

where time is 2 minutes and speed is 46 meters per minute. Therefore:

distance in rain = 2 minutes x 46 meters per minute = 92 meters

So, Adriana drove 92 meters in the rain.

4. Determine the initial markup percent for a children's department with these figures:

Expenses $92,500. 00


Profit 5%


Employee discounts $2,100. 00


Shortages $1,550. 00


Cash discounts $5,500. 00


Markdowns 3%


Alteration costs $3,500. 0

Answers

The initial markup percentage for the children's department is 37.31%.

How to calculate the initial markup percent

First, we need to calculate the total deductions:

Total deductions = Employee discounts + Shortages + Cash discounts + Alteration costs

Total deductions = $2,100 + $1,550 + $5,500 + $3,500

Total deductions = $12,650

Next, we need to calculate the total cost:

Total cost = Net sales - Profit + Markdowns + Total deductions + Expenses

Total cost = $270,000 - 5%($270,000) + 3%($270,000) + $12,650 + $92,500

Total cost = $270,000 - $13,500 + $8,100 + $12,650 + $92,500

Total cost = $370,750

Finally, we can calculate the initial markup percentage:

Initial markup percentage = (Total cost - Net sales) / Net sales x 100%

Initial markup percentage = ($370,750 - $270,000) / $270,000 x 100%

Initial markup percentage = $100,750 / $270,000 x 100%

Answers

From the given information provided, the volume of air in the round house is 64.3 cubic meters.

we need to calculate the volume of cylinder:

The radius of the cylinder is half the diameter, so it's:

r = 4m / 2 = 2m

The volume of the cylinder is then:

V_cylinder = πr²h

V_cylinder = 22/7 x 2² x 2.2

V_cylinder = 30.8 cubic meters

we need to calculate the volume of cone:

The radius of the base of the cone is also 2m, so its volume can be calculated as:

V_cone = 1/3πr²h

V_cone = 1/3 x 22/7 x 2² x 4

V_cone = 33.5 cubic meters

Finally, we add the volumes of the cylinder and the cone to get the total volume of air in the round house:

V_total = V_cylinder + V_cone

The system of equations must have at least one solution because the equations are linearly independent. Also, because the determinant of the coefficient matrix is not equal to zero.

In other words, there is no way to add or subtract the equations from each other to get a zero result. This means that there must be at least one solution to the system of equations. Linearly independent equations means that there is no linear combination of the equations that can equal zero.

Additionally, the determinant of a matrix is a scalar value that can be used to determine if a system of equations has a unique solution, an infinite number of solutions, or no solution. If the determinant of the coefficient matrix is not equal to zero, then the system of equations has a unique solution.

dy/dx = 1 - 2y

Next, we need to substitute x = y - y² into the formula:

S = ∫2π(y - y²)√(1 + (1 - 2y)²)dx

Finally, we need to rearrange the equation to get y in terms of x:

y - y² = x

y² - y + x = 0

How to determine the time they arrive at the destination.

From the question, we have the following parameters that can be used in our computation:

Time = 4 pm

Distance = 64 km

Start by calculating time taken for the father to ride the horse and son to walk the first 32 km:

Time = Distance / (Difference between rates of father and son)

Time = 32 km / (8 km/h - 3 km/h)

Time = 32 km / 5 km/h

Time = 6.4 hours

Calculate time taken for the son to ride the horse and father to walk the remaining 32 km:

Time = Distance / (Difference in Speed)

Time = 32 km / (8 km/h - 4 km/h)

Time = 32 km / 4 km/h

Time = 8 hours

So, we have

Total time = 6.4 hours + 8 hours + 3 hours break + 4 pm
