A linear system is a set of linear equations that can be written in the form ax + by = c, where x and y are variables, a and b are coefficients, and c is a constant.

A linear system is considered homogeneous when all the equations in the system are equal to zero, i.e., they have a constant term of zero. For example, a homogeneous linear system could be:

a linear equation is represented as

2x + 3y = 0

4x - 5y = 0

In this example, both equations are homogeneous because the constant term is equal to zero.

The sum of p, q, and r is 27.

The point of intersection of the lines t1 and t2, (x,y), can be found by using the equation of the lines. The equation of t1 is y=mx+c, where m is the slope, and c is the y-intercept. The equation of t2 is y=mx+c, where m is the slope, and c is the y-intercept.

The equations of t1 and t2 can be written as y= 1/2 x + 1 and y= -1/4 x + 7/2 respectively.

By setting the two equations equal to each other, we can find the x-coordinate of the point of intersection (x,y).

x=2 - 7/4 =4/4 - 7/4 = -3/4

Since x=p−q√r, we can write -3/4 = p−q√r.

Rearranging this equation, we get p+q+r= 4/3 + 7/3 + 4/3 = 27/3 = 9.

Therefore, P+Q+R=27.

Therefore, the sum of p, q, and r is 27.

Step-by-step explanation:

The indefinite integral of sin(16x) with respect to x cannot be expressed in terms of elementary functions.

LaTeX, you can display powers using the caret (^) symbol. For example, to display x raised to the power of 2, you would write:

[tex]$x^2$[/tex]

And to display x raised to the power of y, you would write:

[tex]$x^y$[/tex]

To solve this integral, we would typically use numerical or approximate methods, or special functions such as the sine integral or Fresnel integrals.

The indefinite integral of [tex](1 + cos^2(16x))[/tex] with respect to x can be evaluated using the substitution u = cos(16x). The derivative of cos(16x) with respect to x is -16sin(16x), so the integral becomes:

[tex]∫ (1 + cos^2(16x)) dx = ∫ (1 + u^2) du[/tex]

[tex]= 1/3 u^3 + u[/tex]

[tex]= 1/3 cos^3(16x) + cos(16x) + C[/tex]

where C is the constant of integration.

The intercept of a graph is a point at which the graph crosses either the x-axis or the y-axis. For a graph with an x-intercept, the y-coordinate is 0 and the x-coordinate gives the value at which the graph intersects the x-axis.

For a graph with a y-intercept, the x-coordinate is 0 and the y-coordinate gives the value at which the graph intersects the y-axis. In the context of a line or a linear regression model, the intercept is the value of the dependent variable (y) when the independent variable (x) is 0.

To find the number of cupcake boxes that fit in the larger box, we need to find the volume of the larger box and divide it by the volume of one cupcake box.

The volume of the larger box is 10.5 x 7 x 7 = 572.5 cubic inches.

The volume of one cupcake box is 3.5 x 3.5 x 3.5 = 42.375 cubic inches.

Dividing the volume of the larger box by the volume of one cupcake box, we get 572.5 / 42.375 = 13.5.

So, 13.5 cupcake boxes will fit in the larger box.

The number of cakes that Andy, Betty, and Colin have will be 13, 52, and 16, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Andy has x cakes, Betty has 4x cakes, and Colin has x + 3. Then the equation is given as,

0.65(x + 4x + x + 3) = £52.65

Simplify the equation, then we have

0.65(x + 4x + x + 3) = £52.65

6x + 3 = 81

6x = 78

x = 13

Then the number of cakes that Betty has is given as,

4x = 4 (13)

4x = 52

Then the number of cakes that Colin has is given as,

x + 3 = 13 + 3

x + 3 = 16

You can use the fact that both the cars were travelling at the same speed so we can take them equal to some variable.

The speed of the cars was 0.8 miles per hour

How to form may you can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

How  to find the speed of the cars?

Supposing that both the cars were travelling with the speed

Let the first car travels  miles

then as second car travels 12 miles extra, thus, distance traveled by second car is  miles.

Using the formula for speed, we have:

For first car:

Distance traveled =  miles

Speed =

Time taken =

Thus,

For second car:

Distance traveled =  miles

Speed =

Time taken =

Thus,

So, we got system of 2 linear equations in two variables.

Using the expression for x from first equation and substituting it in second equation, we get

Substituting this value in first equation to get the value of x

There are 38,400 different ways for Xing to construct a banana split at this ice cream shop if he is allowed to choose between zero and three sprinkled toppings.

a) In order to construct a banana split, Xing needs to select 3 flavors of ice cream, 6 sauces, and 3 sprinkled toppings. Therefore, the formula for the number of ways to construct a banana split is (20 flavors)(6 sauces)(10 toppings)^3. When calculated, this number is 28,800. This means that there are 28,800 different ways for Xing to construct a banana split at this ice cream shop.

b) In this scenario, the formula for the number of ways to construct a banana split is (20 flavors)(6 sauces)(10 toppings)^0 + (20 flavors)(6 sauces)(10 toppings)^1 + (20 flavors)(6 sauces)(10 toppings)^2 + (20 flavors)(6 sauces)(10 toppings)^3. When calculated, this number is 38,400. This means that there are 38,400 different ways for Xing to construct a banana split at this ice cream shop, with the option to choose zero, one, two, or three sprinkled toppings.

A function is composite when the co-domain of the first mapping is the domain of the second mapping

We shall evaluate the domain of the function (f - g)(4) as follows:

(f - g) = 4x - 3 - (x³ + 2x)

(f - g) = 4x - 3 - x³ - 2x

(f - g) = 2x - 3 - x³

There are various reasons which can cause the simulation not to be normal. The main reason for this if the sample size is not big enough. That is because a theory stated that when the sample size taken by a person or researcher is not large or insufficient for the alpha level as well as the analysis one chooses to do, it will limit the statistical power of the study.

Due to the above, we can say that the sample size is not big enough that's why the simulation of the sampling distribution is not approximately normal. So option (b) is correct.
