The point [tex](-1\frac{3}{4},4\frac{1}{2})[/tex] has been plotted on the coordinate plane.

Given the point [tex](-1\frac{3}{4},4\frac{1}{2})[/tex]

The coordinate plane is used to graph the points, lines and other objects.

First we have to convert the mixed fraction to the simple fraction

[tex]-1\frac{3}{4}[/tex] = -7/4

[tex]4\frac{1}{2}[/tex] = 9/2

Now we have to convert the simple fraction to decimal form

-7/4 = -1.75

9/2 = 4.5

The point is (-1.75,4.5)

Here the condition of axis is given, the horizontal axis is goes from -5 to 5, that is -5 < x < 5, and the vertical axis goes from -5 to 5 that is -5 < y < 8

Plot the points on the coordinate plane  

Hence, the point [tex](-1\frac{3}{4},4\frac{1}{2})[/tex] has been plotted on the coordinate plane.

Answer:

  1) CW 270° or CCW 90°

Step-by-step explanation:

In each case, you want to identify two transformations that will map the preimage to the image.

We note the transformation maps ...

  A(-7, 0) ⇒ A'(0, -7) . . . . . . CCW 90° or CW 270°

  B(-4, -1) ⇒ B'(1, -4)

  C(-7, 3) ⇒ C'(-3, -7)

These can be described by ...

  (x, y) ⇒ (-y, x)

This transformation is equivalent to either of the two transformations ...

As above, rotation about the origin by 90° in one direction is the same as rotation 270° about the origin in the other direction. The attached graph shows the result either way. The two equivalent transformations are ...

The coordinate transformation is ...

  (x, y) ⇒ (y, -x)

The question states:

Notice that the angle for which its measure is arctan(a/b), is the angle that has "a" as the oposite side, and "b" as the adjacent side , so it is the angle on the bottom right of the triangle.

Then the cosine of that angle, is defined as:

cos(angle) = adjacent/hypotenuse = b / squareroot( a^2+b^2)

which agrees with answer D in the list of possible answers given.

To find the area of the shaded region, we have to find the area of the square first.

Then, we find the area of each yellow triangle inside (up and down). The base of each triangle is 10 inches, and the height of each of them is 7 inches.

Add the area of both triangles.

At last, subtract the area of the triangles from the area of the square.

The strategy is to subtract the area of the yellow triangles (up and down) from the area of the square.

You have the following function for the height respect to the water, Jason has after time t he jumped:

In order to determine the time Jason takes to hit the water, equal h = 0. Thus, you have a quadratic equation and it is necessary to find the zeros of the polynomial:

use the following quadratic formula to find the zeros:

where a,b and c are the coefficients of the polynomial:

a = -16

b = -16

c = 672

replace these values into the formula:

Then, you obtain the following two values:

Select the positive values because negative time does not have physical meaning.

Hence, Jason takes 6 seconds to hit the water.

Answer:

SSS.

Step-by-step explanation:

The text above described the Side-Side-Side Theorem, which states that two triangles are congruent if three sides of one are equal or proportional respectively to three sides of the other (SSS=SSS).

04) The complementary angles are the angles whose sum is 90° thus { 26°,54°,48°,29°,22°} will be the corresponding angles.05)The supplementary angles are the angles whose sum is 180° thus {54°,48°,12°,135°,91°} will be the corresponding angles.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

If m∠A + m∠B = 90° then A and B will be the complimentary angle.

The complementary of 64° = 90° - 64° = 26°

The complementary angle of 36° = 90° - 36° = 54°

The complementary angle of 42°= 90° - 42° = 48°

The complementary angle of 51°= 90° - 51° = 29°

The complementary angle of 68°= 90° - 68° = 22°

If m∠A + m∠B = 180° then A and B will be the supplementary angle.

The supplementary of   = 180° - 126°  = 54°

The supplementary of   = 180° -  132° = 48°

The supplementary of   = 180° - 178°  = 12°

The supplementary of   = 180° -   45° = 135°

The supplementary of   = 180° -  89°  = 91°

Hence " { 26°,54°,48°,29°,22°} will be the corresponding complementary angle and {54°,48°,12°,135°,91°} will be the corresponding supplementary angles".

The main goal is 140 percent i.e., 21 members.

What is meant by percentage?

In mathematics, a percentage (from Latin: percentage , "by a hundred") may be a number or ratio expressed as a fraction of 100. it's often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" also are used. A percentage may be a dimensionless number (pure number); it has no unit of measurement. The term "percent" springs from the Latin per centum, meaning "hundred" or "by the hundred". The Italian word per cento, which means "for a hundred," gradually shrank to become the symbol for "percent." The "per" was often abbreviated as "p."—eventually disappeared entirely. The "cento" was contracted to 2 circles separated by a horizontal line, from which the fashionable "%" symbol is derived.

140 percent of 15 = 15x140/100 = 21 members

Hence, the main goal is 21 members.

The expressions from least to greatest is (√3)² < 8² < 29².

How to compare expressions with indices?
Expressions with indices are of three types:
(1) when bases are equal and powers are different;
(2) when powers are equal but bases are different;
(3) when both powers and bases are unequal.
To solve an expression of type (1), we compare the powers for the given expressions only to determine the greater number efficiently, no heed needs to be given to the base.
To solve an expression of type (2), we compare the bases for the given expressions only to determine the greater number efficiently, no heed needs to be given to the powers.
To solve an expression of type (3), we reduce the power of an expression until it matches the other, so that for comparison only bases are to be taken into consideration without any heed to powers.

Given the expressions are 29², 3 and 64
The given expressions can be re-written as: 29², (√3)² and 8².
On comparing the expressions with the above literature, they match type (2), thus following the assertions we should compare the bases only to find the greatest number.
Thus, the correct order for expressions is: (√3)² < 8² < 29²

Sum of 9 in a pair of dice can occur in the following 4 ways.

3 + 6

4 + 5

5 + 4

6 + 3

Also, total number of ways = 6*6 = 36

1/9 +  Probability of not getting a sum of 9 = 1

Probability of not getting a sum of 9 = 8/9

Also,

Probability of getting the sum of 9 atleast 1 + probability of getting the sum 9 none of the times = 1

Hence, we can write,

Probability of getting the sum of 9 atleast once =  1 - probability of getting the sum 9 none of the times/

Congruent shapes are produced by combining rotations, reflections, and translations. In fact, any pair of congruent shapes can be matched to one another by combining one or more of these three transformations.

A point, line, or geometric figure can be transformed into one of four different shapes or locations. Pre-Image refers to the shape of the object prior to transformation, whereas Image refers to the location and shape of the object after transformation.

Given information

We now know that the size and shape of the figures are preserved during stiff transformations (reflections, translations, and rotations). The pre-image and the actual image concur completely.

The following Matt's transformative skills:

Reflection

Because the The line of reflection remains the same distance away from comparable points from the pre-image to the image.

As a Congruence Transformation - rotations

Rotating a figure causes it to twist. Even though the figure is the same size and shape as before, it appears to have toppled over. A clock is a fantastic example of how the earth actually rotates. Every hour or every day, the clock's connecting arms revolve around their axis. A rotation's degree determines what it is, and common rotations include 90, 180, and 270 degrees. Before going back to its original position, the figure rotates a full 360 degrees. the direction of a rotation, whether it is counterclockwise or clockwise. It is possible to determine the degree, amount, and and the direction of a revolution.

Translational congruence transformation

When an object or shape is transported from one location to another without altering its size, shape, or orientation, the movement is referred to as a translation. During a translation, also known as a slide occasionally, every point on an object or shape is moved by the same amount and in the same direction.

Step-by-step explanation:

27/7

Answer:

The answer to the first question is:
[tex]27[/tex] groups.

And the second answer is:
[tex]\frac{27}{7}[/tex]

Step-by-step explanation:

Step 1: Analyze the number line

As we can see from the number line, each interval equals to [tex]\frac{1}{3}[/tex].

We can prove this by the fact that at the seventh interval, the value is [tex]\frac{7}{3}[/tex].

So, the value between each intervals would be:

[tex]\frac{7}{3}\div 7\\=\frac{1}{3}[/tex]

Step 2: Solving the first question:

We can see that the number [tex]9[/tex] lies on the [tex]27\text{th}[/tex] interval.

Since the value between each interval is [tex]\frac{1}{3}[/tex], it would take [tex]27[/tex] groups of [tex]\frac{1}{3}[/tex] to equal to [tex]9[/tex].

Step 3: Solving the second question:

From the number line, we can see that it takes four groups of [tex]\frac{7}{3}[/tex] to equal to [tex]\frac{28}{3}[/tex].

And since we are taking [tex]\frac{7}{3}[/tex] as a single group here, each interval in a group of [tex]\frac{7}{3}[/tex] would be [tex]\frac{1}{7}[/tex] of the group.

So, the answer of the division would be: [tex]4[/tex] (the number of groups of [tex]\frac{7}{3}[/tex]needed to reach [tex]\frac{28}{3}[/tex]) minus [tex]\frac{1}{7}[/tex] (the amount of the group that when subtracted, brings the entire answer to [tex]9[/tex]):

[tex]4-\frac{1}{7}\\\\\frac{4\times 7}{7}-\frac{1}{7}\\\\=\frac{28}{7}-\frac{1}{7}\\\\=\frac{28-1}{7}\\\\=\frac{27}{7}[/tex]
