The solution of the given system of equation is (-19, 55).

In the given question we have to find the solution to the system of equations:

y = -3x-2 and 5x + 2y = 15

We can solve the system of equation using the substitution method.

In substitution method we have to put the the value of one variable from one equation to the other equation.

We have to equations:

y = -3x-2...................................(1)

5x + 2y = 15.............................(2)

Now putting the value of y from the equation 1 in equation 2

5x + 2(-3x-2) = 15

Now solving the equation using the distribution method.

5x - 6x - 4 = 15

Simplifying

-x - 4 = 15

Add 4 on both side we get

-x = 19

Now the value of x is -19.

Now putting the value of x in equation 1

y = (-3)*(-19)-2

y = 57-2

y = 55

Hence, the solution of the given system of equation is (-19, 55).

As per the combination method, the number of ways can the ribbons be awarded is 24,024

The general formula to calculate the combination is written as,

nCr = n!/r! (n - r)!

where n refers the set or population and r refers subset of n or sample set

Here we have given that there are 14 dogs in a particular class at a dog show. blue, red, yellow, and white ribbons will be awarded to the first through fourth place finishers,

Here we need to find the number of different ways can the ribbons be awarded.

While we looking into the given question, the following details are given in it,

Total number of dogs = 14

Number of ribbons = 5

Which means that the value on n = 14 and the value of r = 5.

As per the given question we know that,

There are 14 possibilities for blue one

And then there are 14 - 1 = 13 possibilities for red ribbon.

And for the next yellow one has 12 possibilities

Then the white one has 11 possibilities.

Therefore, the total number of ways is

=> 14 x 13 x 12 x 11

=> 24024

Therefore, option (c) is correct.

The simple interest is $6,240.00.

The term simple interest refers the interest that is only calculated on the initial sum borrowed or deposited.

Here we need to find  the simple interest on $6000 from 16 may 2010 to 9 October 2010 at 10% per annum.

While we looking into the given question, we know te following values,

Principal amount = $6000

Time period = 16 may 2010 to 9 October 2010

The number of days between 16 may 2010 to 9 October 2010 is

=> 146 days.

Here we have the interest for 1 year,

So, the time period is written as,

And then we have to put time into years for simplicity,

146 days / 365 days/year = 0.4 years.

And the interest rate = 10%

Here we have to convert R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year.

Now, we have to apply the values on the formula, then we get by solving our equation:

A = 6000(1 + (0.1 × 0.4)) = 6240

A = $6,240.00

Therefore, the total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 10% per year for 0.4 years (146 days) is $6,240.00.

The side-side-side (SSS) theorem states that if three sides of one triangle are equal to the corresponding sides of another triangle, then the two triangles are congruent.

In other words, if the lengths of the sides of two triangles are the same, then the triangles must be the same shape and size.

For example, consider two triangles ABC and DEF. If we know that

we can use the SSS theorem to conclude that triangle ABC is congruent to triangle DEF.

It is important to note that the SSS theorem is only applicable if the three sides of each triangle are equal in length. If the sides are not equal, the theorem does not apply and we cannot use it to prove the congruence of the triangles.

As per the given equation, the length of the arc of the curve from point p to point q is 1.8973

Here we have given the equation y = 1/2 x².

Then the the length of the arc of the curve from point p to point q is calculated by using the formula,

=> [tex]\int\limits^q_p {\sqrt{1+(\frac{dy}{dx} )^2} } \, dx[/tex]

Here we have to extract the value of (x1, x2) from the given coordinates, then we get,

=> (x1, x2) = (-3, 3)

Now, we have to find the derivative of y, then we get he value as,

=> dy/dx = x

So, the length is calculated as,

=> [tex]\int\limits^3_{-3} {\sqrt{1+x^2} } \, dx[/tex]

As per the power rule of derivative, then reduced form of the equation is written as.

=> [x/√x²+1]₋₃³

When we apply the value of x as the given limit, then  we get,

Discontinuity can be determined by looking for sudden changes in values or jumps in the graph of the function. If there is a break or gap in the graph, the function is discontinuous.

Discontinuity occurs when a function fails to be defined at a certain point within its domain, resulting in a sudden change in the graph of the function. Discontinuity can be determined by plotting the graph and looking for sudden changes in values or jumps in the graph. If the graph shows a break or gap, then the function is discontinuous. Discontinuity can also be determined by examining the behavior of the function at a certain point. If the function values diverge as the point is approached from either side, then the function is discontinuous at that point. Additionally, a function can be discontinuous at a point if it does not obey the rule of continuity, which is that the function's value must be equal to the limit of the function as the point is approached from both sides. If the limit does not exist at a point, then the function is discontinuous at that point.

The total distance traveled by the cows are 3.58 meters. To calculate that we need to calculate fourth area before.

It sounds like you are trying to solve a problem involving two cows grazing in a field and the area that they graze. Here is a possible solution:

We can use the formula for the area of a quadrilateral to solve for the fourth side:

Area = (1/2) x (12 cm) x (fourth side)

Solving for the fourth side, we get:

Fourth side = (20 cm)/(12 cm) = 1.67 meters

Finally, add up the lengths of the four sides to find the total distance traveled by the cows:

Population parameters are used to estimate sample statistics, and this is true.

Population parameters are used to describe the characteristics of a population, such as the mean, median, and standard deviation, and are used to make inferences about a population. Sample statistics, on the other hand, are used to describe the characteristics of a sample of a population. For example, a sample statistic could be the mean of a sample of people's heights.

To estimate sample statistics, population parameters must first be known. For example, the sample mean can be estimated using the population mean. If the population means are unknown, then the sample means can be estimated using the sample mean.

In conclusion, population parameters are used to estimate sample statistics, and this is true. Population parameters provide useful information about a population that can be used to make inferences about a sample. Knowing the population parameters allows researchers to make more accurate estimates of sample statistics, which in turn can be used to make more reliable inferences about a population.

In substitution method we have to put the the value of one variable from one equation to the other equation.

We have to equations:

y = -4x + 10...................................(1)
