The image of triangle CDE after a rotation of 90º counterclockwise around the origin is graphed at the end of the answer.
What is a rotation?When a polygon undergoes a rotation, this rotation is over an angle measure, that defines the coordinate rule for each vertex of the polygon.
For triangle CDE, the vertices are given as follows:
D(-7,-1), C(-7,-7), E(-4,-8).
The rule for a rotation of 90º counterclockwise around the origin, for each vertex (x,y) of the polygon, is given by:
(x,y) -> (-y,x).
Hence, applying the rule above, the vertices of the image of triangle CDE will be given as follows:
D'(1,-7), C'(7,-7), E'(8,-4).
The triangle, with these vertices labeled, is graphed at the end of the answer.

1. One of two supplementary angles is four times the other. Find the largest angle.
Answers
144 is the largest angle in supplementary angle .
What is an example of a supplementary angle?
Angles that add up to 180 degrees are referred to as supplementary angles. For instance, the sum of angle 130° and angle 50° is 180°, hence they are supplementary angles.The pair of angles known as supplementary angles always add up to 180 degrees. The terms "supplements" for these two viewpoints describe them. The Latin terms "Supplere" and "Plere," which mean "supply" and "fill," respectively, are the source of the English word "supplementary."Let one angle = x
then other angle is four times the other = 4x
x + 4x = 180
5x = 180
x = 180/5
x = 36
smaller angle = 36
largest angle = 4x = 4 * 36 = 144

The height till which the ladder will reach the wall will be 3.84 m.
What is defined as the trigonometric identity?Trigonometric Identities come in handy when trigonometric functions are used in an expression or equation. Trigonometric identities hold for all values of variables on both sides of an equation. Geometrically, these identities involve one or more trigonometric functions (including such sine, cosine, and tangent). The principal trigonometry functions are sine, cosine, and tangent, whereas the other three functions are cotangent, secant, and cosecant. All six trig functions are used to derive the trigonometric identities.For the given question,
The distance between the base of the ladder and the wall is 1.4 m.
The angle made by base of the ladder to the floor is 70 degree.
Let the height till which the ladder goes be 'h'.
Then, applying the trigonometric identity.
tan 70 = h/1.4
h = 1.4 × tan 70
h = 3.84 m
Thus, the height till which the ladder will reach the wall will be 3.84 m.

Plot the image of point D under a dilation about the origin (0,0) with a scale factor of 2
Answers
The coordinates of the image of point D are (- 6, - 4) and a representation of the rigid transformation is shown in the picture attached below.
How to determine the location of the image of a point set on Cartesian plane
Herein we find the location of point D, which is set on Cartesian plane and must be modified by the use of a rigid transformation known as dilation. The general definition of the dilation rule is defined below:
D'(x, y) = O(x, y) + k · [D(x, y) - O(x, y)]
Where:
O(x, y) - Center of dilation.k - Scale factorD(x, y) - Coordinates of the point.D'(x, y) - Coordinates of the image.If we know that O(x, y) = (0, 0), D(x, y) = (- 3, - 2) and k = 2, then the coordinates of the image are:
D'(x, y) = (0, 0) + 2 · [(- 3, - 2) - (0, 0)]
D'(x, y) = (- 6, - 4)
Now we proceed to present the location of the image on the Cartesian plane.

find the number of calories in a stalk of celery and in a carrot, a carrot hs 13 calories more then a celerystalk, five carrots and 1o celery stalks have only 170 calories
Answers
The number of calories in stalk of celerystalk and carrot is found as 20 and 7 respectively.
What is defined as the method of substitution?The algebraic method for solving simultaneous linear equations is the substitution method. The value with one variable through one equation is replaced in the other equation, as the name implies.For the given question;
Let the number of calories present in carrot is 'x'.
Let the number of calorie present in celerystalk is 'y'.
Carrot has 13 more calories than celerystalk.
Thus,
x = y + 13 ......eq 1
Now, 5 carrots and 10 celery stalks have total 170 calories.
The equation becomes.
5x + 10y = 170
Substitute the value of x from eq 1.
5(y + 13) + 10y = 170
Simplify the equation;
5y + 65 + 10y = 170
15y = 105
y = 7 (number of calories in stalk of celerystalk)
Put the value of y in eq 1.
x = y + 13
x = 7 + 13
x = 20 (number of calories in stalk of carrot)
Thus, the number of calories in stalk of celerystalk and carrot is found as 20 and 7 respectively.

Answers
Given the transformations of the graph of f(x)=6x, the function rule g(x) is therefore g(x) = -1/2x.
What is transformation?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location. Transformations can be divided into four categories: translation, rotation, reflection, and enlargement. You must be able to carry out each transformation and recognize which ones have already been done.
Given Data
f(x) = 6x
The resulting function will be f(x) = -6x if the function is not reflected over the x-axis.
The final function rule will be; if the resulting function is compressed by a factor of 1/12.
g(x) = 1/12(-6x)
g(x) = -1/2x
Given the transformations of the graph of f(x)=6x, the function rule g(x) is therefore g(x) = -1/2x.

Answers
The value of the fraction given as - 1 3/4 - (-8 1/3) - (- 4 1/4) will be 10 5/6.
How to calculate the fraction?It should be noted that a fraction is simply used to represent the numbers that aren't whole. The commutative property of addition states that the sum is unaffected by the order of the addends.
According to the associative property of addition, the grouping of integers does not affect the sum.
Based on the information given, the fraction is illustrated as:
= - 1 3/4 - (-8 1/3) - (- 4 1/4)
Note that (-) × (-) = +
Therefore,
= - 1 3/4 - (-8 1/3) - (- 4 1/4)
= - 1 3/4 + 8 1/3 + 4 1/4
The LCM of the denominator is 12

Answers
There is a 0.75 percent chance that the person is a woman with long hair.
What is probability?Probability can be used to define potential. The occurrence of a random event is the focus of this mathematical field. There is a 0 to 1 value range. The likelihood of anything happening is often referred to as probability. Utilize probability to gauge a situation's likelihood of happening. Numerous factors are difficult to forecast with absolute precision. Using it, we can only speculate on whether or how likely it is that an event will occur. A probability scale with a value of 0 for an impossibility and 1 for a certainty. In a sample space, there is a one probability for every event.
E is the probability of an event . Hence,
P(E) is the ratio of favorable results to all outcomes.
In probability, an event is deemed dependent if it is impacted by other occurrences, and independent if it is wholly unaffected by the occurrence of any other event.
By applying the literature and formulas previously mentioned, we have:
F should signify for the fact that the student is female, and L should stand for the fact that the student has long hair.
P(F)
= 0.60
P(L)
= 0.50
P(F AND L)
= 0.45
P(L|F)
