What two events are independent

27.5 hrs are  long did she walk take to cover distance .

In math, what is a distance?

The length of the segment of the line that connects the supplied two points determines the distance between them.

                    The shortest segment of a line connecting a point to a line will have a length equal to the distance between them.

Distance covered by Alliosn =  1/2 km

Time taken by Alliosn  = 1/5hr

Hence,

speed of peter = Distance/time

= (1/2)/(1/5) km/hr

= 1/10 km/hr

Distance travelled by Alliosn = 1  1/4 km

=  11/4km

Speed = distance/time

1/10 = (11/4) / time

i.e.

Time = 11 * 10/4

       = 27.5 hrs

JL has a length of 5.

The internal angles of a rectangle, which has four sides, are all exactly 90 degrees.

At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.

For instance, if the length of one side of a rectangle is 20 cm, the opposing side will also be 20 cm.

A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle.

It is also known as an equiangular quadrilateral for this reason.

Rectangles can also be referred to as parallelograms because their opposite sides are equal and parallel.

According to our question-

d).  A ball with radius r, lying inside a glass described by the function y = x^2, has its center at (0, F(r)) units above the bottom of the glass. f(2) - f(1/4)=4.

To solve this problem, we first need to find the function F(r). We can do this by finding the y-coordinate of the center of the ball when its radius is r.

Since the ball lies inside the glass described by the function y = x2, the y-coordinate of the center of the ball when its radius is r is equal to the y-coordinate of the point (r,r2).

Thus, the function F(r) is given by F(r) = r2. Now, we can calculate f(2) - f(1/4) = F(2) - F(1/4) = 22 - (1/4)2 = 4 - 1/16 = 4 - 0.0625 = 3.9375 ≈ 2. Therefore, f(2) - f(1/4) = 2.

On solving the provided question, we can say that angle are given a 9n - 3 + 8n +9 = 60; angle 1 = 24 and angle 2 = 33

In Euclidean geometry, an angle is a shape made up of two rays, referred to as the angle's sides, that meet at a point in the middle known as the angle's vertex. Two rays can generate an angle that is in the plane where the rays are located. The meeting of two planes also creates an angle. They are referred to as dihedral angles. An angle is the shape created by two rays or lines that have a shared termination in plane geometry. The Latin word "angulus," which meaning "horn," is the source of the English term "angle." The vertex is the common terminal of the two rays, which are referred to as the sides of the angle.

angle are given as

9n - 3 + 8n +9 = 60

Step-by-step explanation:

The slope-intercept form of the given linear equation 2x + y = 10 is y = -2x + 10.

If we draw the graph of the linear equation y = mx + c. The result is a line with m as the slope, and c as the y-intercept. This form of the linear equation y = mx + c is called the slope-intercept form, and the values of m and c are real numbers.

The slope, m, of the line represents the steepness of a line. This is also termed a gradient, sometimes. The y-intercept, c, represents the y-coordinate of the point where the graph of the line intersects the y-axis.

Now, change the given equation to slope-intercept form, y = mx + c, where m is the slope and c is the y-intercept.

2x + y = 10

Subtract 2x from both sides of the above equation, we get

y = -2x + 10

This is the required slope-intercept form of the given linear equation.

The points A(3,-2), B(-3, 8), C(-5, -1) and D(2,16) would form a parallelogram.

How to plot points on graph?

In mathematics, points on a graph are typically plotted on a coordinate plane. The x-coordinate and y-coordinate of each point determine its location on the plane. To plot a point, you will need to know its coordinates (x, y).

To plot the points A(3,-2), B(-3, 8), C(-5, -1) on the coordinate axes, we can start by drawing the x-axis and y-axis, where the x-axis is the horizontal line and y-axis is the vertical line.

We can then locate point A by starting at the origin (0,0) and moving 3 units to the right on the x-axis and 2 units down on the y-axis. Point B can be located by starting at the origin and moving 3 units to the left on the x-axis and 8 units up on the y-axis. Point C can be located by starting at the origin and moving 5 units to the left on the x-axis and 1 unit down on the y-axis.

To form a parallelogram, point D must be opposite of point B and have the same distance from point C and point A. Since a translation of a vector is a linear transformation, D is the translation of vector AB to point C.

The coordinates of point D would be (2,16), which is the translation of point B by the vector (2,8) to point C.

So the points A(3,-2), B(-3, 8), C(-5, -1) and D(2,16) would form a parallelogram.

Antonio's budget line has shifted upwards due to a 50 percent increase in the price of new books and a 20 percent increase in the price of used books. His new budget line equation is y = 110x.

Upper L1: y = 80x

The function is given by: h(x) = -2(x³ - 2x² - 5x + 6).

The factor theorem in algebra connects a polynomial's components and zeros. The polynomial remainder theorem has this particular special instance. A polynomial f(x) has a factor if and only if f=0, according to the factor theorem.

The Factor Theorem states that a polynomial function with roots [tex]$x_1, x_2, x_n$[/tex] is given by:

[tex]$$f(x)=a\left(x-x_1\right)\left(x-x_2\right) \cdots\left(x-x_n\right)$$[/tex]

In which a is the leading coefficient.

Looking at the table, considering the values of x when h(x)=0, the roots of h(x) are given as follows:

[tex]$$x_1=-2, x_2=1, x_3=3$$[/tex]

Then the rule is:

h(x) = a(x + 2)(x - 1)(x - 3)

h(x) = a(x² + x - 2)(x - 3)

h(x) = a(x³ - 2x² - 5x + 6)

The h-intercept is of -12, as when x = 0, h = -12, hence this is used to find a as follows:

6a = -12

simplifying the above equation, we get

a = -12/6

a = -2.

Answer:A′(−1, 1.5), B′(−0.5, 0.5), C′(1, −0.5), D′(1, 1).

Step-by-step explanation:

To dilate a point using a scale factor, you multiply both the x-coordinate and the y-coordinate of the original point by the scale factor.

Given the original vertices of the polygon ABCD and a scale factor of one fourth (1/4), we can find the coordinates of the dilated vertices A', B', C', and D':

Original vertex A(-4, 6):

x-coordinate of A': -4 * 1/4 = -1

y-coordinate of A': 6 * 1/4 = 1.5

So, vertex A' is (-1, 1.5).

Original vertex B(-2, 2):

x-coordinate of B': -2 * 1/4 = -0.5

y-coordinate of B': 2 * 1/4 = 0.5

So, vertex B' is (-0.5, 0.5).

Original vertex C(4, -2):

x-coordinate of C': 4 * 1/4 = 1

y-coordinate of C': -2 * 1/4 = -0.5

So, vertex C' is (1, -0.5).

Original vertex D(4, 4):

x-coordinate of D': 4 * 1/4 = 1

y-coordinate of D': 4 * 1/4 = 1

So, vertex D' is (1, 1).

Comparing the calculated coordinates with the options given:

A′(−1, 1.5), B′(−0.5, 0.5), C′(1, −0.5), D′(1, 1)
