What are the slopes of the point o,2 1 , -1

Answers

The slope of the line that goes through the points (0, 2) and (1, -1) is -3.

What is the slope of the line?

The slope of a line is a number that describes the steepness of a line and the direction it is heading. It is also known as the "rise over run" or the "rate of change" of a line. The slope of a line is typically represented by the letter "m" and is found using the formula:

slope = (y2 - y1) / (x2 - x1)

To find the slope of a line, you need two points on the line (x1, y1) and (x2, y2) and substitute their coordinates into the slope formula.

To find the slope of a line, we use the formula:

slope = (y2 - y1) / (x2 - x1)

In this case, we have two points: (0, 2) and (1, -1). To find the slope between these two points, we can substitute their coordinates into the slope formula:

slope = (-1 - 2) / (1 - 0)

slope = -3

Hence, the slope of the line that goes through the points (0, 2) and (1, -1) is -3.

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x ax²+bx+c=0. with a ≠ 0 .

It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem.

Given:

F(x) = x² + 3x - 40

Now, solving the quadratic Equation

x² + 3x - 40 = 0

x² + 8x - 5x - 40 = 0

x(x + 8) - 5(x + 8)=0

(x+8) (x-5)= 0

So, x+8 = 0 or x-5=0

What is linear function ?  

Two distinct but related concepts are referred to as linear functions in mathematics. A polynomial function of degree 0 or 1 is a linear function in calculus and related subjects if its graph is a straight line. Any function that depicts a straight line on a coordinate plane is said to be linear. For instance, y = 3x - 2 is a linear function since it depicts a straight line on the coordinate plane. f(x) = 3x - 2 can be used to represent the function since f(x) can be linked to y.

the pet owners, 12 prefer dogs to cats. Of the 8 non-pet

selecting a student from the class who is a pet owner or

Answers

The probability of selecting a student from the class who is a pet owner or prefers cats to dogs is; 0.4

What is the probability of selection?

In probability, If events A and B are not mutually exclusive, then the probability of A or B is expressed as;

p(A or B) = p(A) * p(B).

Total number of students = 26

Total number of students that are pet owners = 18

Total number of students that prefers cats to dogs = 26 - (8 + 3) = 15

Thus;

P(pet owner) = 18/26

P(prefers cats to dogs) = 15/26

P(Pet owner or prefers cats to dogs) = (18/26) * (15/26)

Draw a graph of the signed area represented by the integral and compute it using geometry. (Use symbolic notation and fractions where needed.)

Answers

The integral represents a graph of the signed area, and the geometry is calculated. The area is found to be 100 units².

A plane that is created when two perpendicular coordinate axes cross each other is known as a cartesian plane. Everywhere in the Cartesian plane, the functions define the boundaries of regions with regular geometrical patterns. The right triangle and other regular regions are good examples of how the area of a region may be computed using the geometry of the region.

The given function is [tex]\int\limits^{10}_{-10} {|x|} \, dx[/tex].  The function of this integrand is defined as f(x)=|x| with -10 ≤ x ≤ 10. Now, the graph is drawn for this function.

From the graph, we can tell the base and height of the two right-angle triangles are 10 units and 10 units. Then, the area is,

[tex]\begin{aligned}A&=2\left(\frac{1}{2}\times b\times h\right)\\&=2\times \frac{1}{2}\times 10 \times 10\\&=\mathrm{100\;{units}^2}\end{aligned}[/tex]

The area can also be calculated by solving the integrals,

[tex]\begin{aligned}\int\limits^{10}_{-10} {|x|} \, dx &=\int\limits^0_{-10} {-x} \, dx +\int\limits^{10}_0 {x} \, dx\\&=\left[\frac{x^2}{2}\right]^{0}_{-10} +\left[\frac{x^2}{2}\right]^{10}_{0}\\&=\frac{1}{2}(100+100)\\&=\mathrm{100\;units^2}\\\end{aligned}[/tex]

11) A plane travels 160 miles on a bearing of 327°. It then changes direction and travels 205 miles on a
bearing of 311°. How far is the plane from its original position?
2051/

Answers

2051/2 miles,The plane is travelling in a different direction from its original position, and the distance from the original position can be calculated by using the Law of Cosines.

How far is the plane from its original position?The plane's displacement from its original position can be calculated by finding the magnitude of the vector sum of the two displacements.The first displacement can be calculated using the magnitude of the vector, the bearing, and the formula for the magnitude of a vector in polar coordinates. The magnitude of the vector is equal to the distance traveled (160 miles) multiplied by the cosine of the bearing (327°). Therefore, the magnitude of the first displacement is 149.9 miles.The second displacement can be calculated in the same manner. The magnitude of the vector is equal to the distance traveled (205 miles) multiplied by the cosine of the bearing (311°). Therefore, the magnitude of the second displacement is 176.7 miles.The vector sum of the two displacements can be found by adding their respective x-components and y-components. The x-component of the first displacement is negative 149.9 miles, and the y-component is 131.8 miles. The x-component of the second displacement is negative 176.7 miles, and the y-component is 114.2 miles. The x-component of the vector sum is −326.6 miles, and the y-component is 246 miles.This problem is an example of vector addition. Vector addition is a mathematical process used to calculate the resultant displacement of two or more vector quantities. It is the process of combining two or more vectors to produce a vector that points in the same direction as the total of the individual vectors. In this case, we can use vector addition to find the distance from the plane's original position.

What is slope?

An indication of how steep a line is is its slope. When calculating slope mathematically, "rise over run" is used (change in y divided by change in x). The ratio of how much y grows as x grows by a certain amount is known as the slope of a line. A line's slope, or the amount by which y rises as x rises, indicates how steep a line is. The slope is constant (the same) along the line.

Here from given tables lets take any two points to find slope, then

[tex](x_1,y_1)=(0,-6) and (x_2,y_2)=(1,0)[/tex]

Now using slope formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] then

=> m = [tex]\frac{0-(-6)}{1-0}[/tex]

=> m =[tex]\frac{6}{1}[/tex]

=> m = 6.

Answers

The probability of getting a household income of $75,000 in Maryland is 0.3989.

The normal distribution formula is given by:

P(x) = 1/√(2πσ^2) * e^[-(x-μ)^2 / (2σ^2)]

Using substitution method to solve the system of linear equation, the number of children is 90 and adults is 93.

What is System of Linear Equation

In mathematics, a system of linear equations is the collection of two or more linear equations that share the same variables. The maximum power of the variable in the linear equations in this situation is 1, making them first-order equations. A linear equation may have one, two, or three variables. We can therefore create linear equations with n variables.

To solve this problem, we have to define our variables and then write the equations.

Let;

x = childreny = adult

x + y = 183 ...eq(i)

1.75x + 2.5y = 390 ...eq(ii)

solving both equations

From equation (i)

x + y = 183

x = 183 - y ...eq(iii)

Put equation (iii) into equation (ii)

1.75(183 - y) + 2.5y = 390

y = 93

Put y = 93 into equation (i)

x + 93 = 183

x = 90

Notice that f(x) and g(x) have been changed into y. The reason is because f(x) and g(x) are the same and stand for y, but we only use f and g to distinguish between the 2 equations. We can use equal values to solve.

[tex](x-3)^2+1=-3x+10[/tex]              [exponent]

[tex]x^2-6x+9+1=-3x+10[/tex]        [add both sides by 3x]

Notice that x=0 and x-3=0. This means the solutions are x=0 and x=3.

To find the actual full solution, we have to plug those points back into the original equations.
