Two angles are complementary. One angle is 4° less than four times the other angle. Find the measures of the angles.

Each midpoint's coordinate is given by the mean of the respective coordinates of the two endpoints of the segment. Then, if we say M is the midpoint of that segment, we have:

Mx = (-4 + 4)/2 = 0/2 = 0

My = [6 + (-2)]/2 = (6 - 2)/2 = 4/2 = 2

Therefore, writing those coordinates as an ordered pair, we have:

M = (0, 2)

Deterministic.

The relationship between the variables is deterministic. A deterministic relationship refers to a relationship in which the dependent variable does not depend on other elements (variables) other than the independent element classified in the relationship. The independent variable (element) in the relationship possesses an exact value. Hence deterministic relationship is also named as the exact relationship between variables.

Answer:

sin2x = 16/65

cos2x = -63/65

tan2x = -16/63

Explanation:

the tangent of an angle is equal to the opposite side over the adjacent side. So, if the tan(x) = 8, we can represent this as the following diagram:

Therefore, we can calculate the value of the hypotenuse as:

With the hypotenuse, we can calculate sin(x) and cos(x) as follows:

We type the negative sign because the question says that sin(x) is negative.

Now, we will use the following trigonometric identities to find sin(2x), cos(2x) and tan(2x)

Therefore, replacing the values, we get:

So, the answers are:

sin2x = 16/65

cos2x = -63/65

tan2x = -16/63

The coordinates of the vertices of the image of the square are S'(x, y) = (- 1, - 4), T'(x, y) = (- 1, 1), U'(x, y) = (4, 1) and V'(x, y) = (4, - 4).

In this problem we need to make use of a translation on a geometric locus on a Cartesian plane, which is generated by four points representing the vertices of the square. The translation is a kind of rigid transformation, whose formula is shown below:

P'(x, y) = P(x, y) + t(x, y)

Where:

If we know that S(x, y) = (- 6, - 5), T(x, y) = (- 6, 0), U(x, y) = (- 1, 0) and V(x, y) = (- 1, - 5) and t(x, y) = (5, 1), then the locations of the vertices of the triangle are:

S'(x, y) = (- 6, - 5) + (5, 1)

S'(x, y) = (- 1, - 4)

T'(x, y) = (- 6, 0) + (5, 1)

T'(x, y) = (- 1, 1)

U'(x, y) = (- 1, 0) + (5, 1)

U'(x, y) = (4, 1)

V'(x, y) = (- 1, - 5) + (5, 1)

It is not possible to write a linear inequality such that the solution contains only positive values of x and y.

This happens because every line on the coordinate plane must have a y-intercept and/or an x-intercept. When the line crosses an axis, either the variable x or y changes its sign.

Given

x - y + (- z) where x and z are positive real numbers and y is a negative real number.

Find

i) What are the directions of motion for this calculation ?

ii) Is the final answer positive , negative , or undetermined ?

Explanation

i) as we have given

x - y + (- z)

x - y - z

(x - y) - z

right -left - left

ii) for this we take examples

let x = 2 , y = -1 and z = 2

2- (- 1) + (- 2) = 1 , positive

now

let x = 2 , y = -1 and z = 5

2 - (- 1) + (- 5) = 3 - 5 = -2 , negative

In terms of the calculation, the answer is 39/4 in improper fraction.

An improper fraction has a denominator that is greater than or equal to the numerator. Based on the numerator and denominator values, proper fractions and improper fractions are the two main types of fractions in mathematics.

A mixed fraction is a fraction formed by combining a natural number and a proper fraction. It is a shortened version of an improper fraction.

The given equation is [tex]3\frac{1}{4}[/tex] + [tex]6\frac{1}{2}[/tex] .

Taking 4 as LCM from the above equation.

[tex]3\frac{1}{4}[/tex] + [tex]6\frac{1}{2}[/tex] = (13/4) + (13/2)

[tex]3\frac{1}{4}[/tex] + [tex]6\frac{1}{2}[/tex] = (13+26)/4

[tex]3\frac{1}{4}[/tex] + [tex]6\frac{1}{2}[/tex] = 39/4

Now, since the solution must be proffered in an improper fraction.

Therefore, the obtained improper fraction is 39/4.

Percentage of the student body exists at least 21 years old exists 50%.

A continuous probability distribution for a real-valued random variable in statistics is known as a normal distribution or Gaussian distribution.

As one moves away from the center, values start to taper off and the majority of values are concentrated in this area. In a normal distribution, the mean, mode, and median are identical measures of central tendency.

When given a normal or Symmetric distribution, the mean of the distribution exists at the center with 0.5 or 50% of the distribution to either side (right and left) of the distribution.

Therefore, if the mean = 21 ; then the percentage of student body with at least 21 years is the percentage to the left of the distribution, which exists 50%.

P(x ≤ 21) = 0.5 = 50%

Therefore, 50 percentage of the student body exists at least 21 years old

Step-by-step explanation:

The sum of  -1  and 3/4 and 2 and 1/2 is the same as the difference between 2 and 1/2 and 1 and 3/4.

First we will convert the mixed fractions into improper fractions.

-1 and 3/4 = -7/4

2 and 1/2 = 5/2

Sum of -1 and 3/4 and 2 and 1/2 = -7/4 + 5/2 = -7/4 + 10/4 = 3/4

Difference between  2 and 1/2 and 1 and 3/4 = 5/2 - 7/4 = 10/4 - 7/4 = 3/4

As both the values equal to 3/4 , we can say that the sum of  -1  and 3/4 and 2 and 1/2 is the same as the difference between 2 and 1/2 and 1 and 3/4.

Based on the linear relationship between the ticket numbers and the total cost, the cost of one ticket can be found to be A. $10.50

First, find the rate of change in ticket pricing assuming the number of tickets is x and the total cost is y.

The rate of change is:

= Change in y / Change in x

= (67.50 - 46.50) / (5 - 3)

= $10.50

Then find the y-intercept:

y = Slope(x) + y-intercept

67.50 = 10.50(5) + y-intercept

y-intercept  = 67.50 - 52.50

y-intercept = 15

Linear equation is:

Total cost = Rate of change (Tickets) + y-intercept

Now, we transform it to radians:

*Second: We replace on the equation:

So, the area of the green sector is 69pi/5 square centimeters. [Approximately 43.4 square centimeters]

Answer:

A ≈ 43.4 cm²

Step-by-step explanation:

the area (A) of the green sector is calculated as

A = area of circle × fraction of circle

  given d = 12 then r = 12 ÷ 2 = 6 cm

the central angle of the green sector = 180° - 42° = 138°

then

A = πr² × [tex]\frac{138}{360}[/tex] ( simplify fraction by dividing numerator/denominator by 6 )

   = π × 6² × [tex]\frac{23}{60}[/tex]

Step-by-step explanation:

Cos theta = B/h = 8/21

theta = 67.6 °

Step-by-step explanation:

imagine the triangle being flipped upwards around DE, so that F is on top instead of on the bottom.

then you see clearly that

DF (21) is the radius of the trigonometric circle,

DE is cos(angle D)×radius,

EF (8) is sin(angle D)×radius.

so,

8 = sin(angle D)×21

sin(angle D) = 8/21 = 0.380952381...

angle D = 22.39268781...° ≈ 22.4°

and so, something is wrong with your problem definition.

the answer options seem to aim for angle F, for which EF (8) is the cosine × radius.

but for angle D EF is clearly the sine × radius.

and for answer option b (20.9°) EF would have to be about 7.5 units long (with the radius DF still being 21). that is all too much off.

The value of g(a) + h(a) is a²-3a-2 or (a-2)(a-1) using addition of functions.

Given a collection of inputs X (domain) and a set of potential outputs Y (codomain), a function is more technically defined as a set of ordered pairings (x,y) where x belongs to X  and y belongs to Y, with the caveat that there can only be one ordered pair with the same value of x. The function notation f:XY can be used to express that f is a function from X to Y

Adding two functions-

g(a) = a²- 2

h(a) = -3a

Let h(a) be g(a) + h(a)

So h(a) = a² - 2 - 3a.

We can factorize the function into (a-2)(a-1).

The amount of coffee she bought is 5.16 pounds.

She received a $70 gift card for a coffee store.

She used it in buying some coffee that cost $8.36 per pound after buying a coffee she had $26.85 left.

Therefore, base on the card, the number of pounds of coffee she bought can be calculated as follows;

Hence,

let

the amount of coffee she bought in pounds = x

Hence,

70 = 8.36x + 26.85

70  - 26.85 = 8.36x

43.15 = 8.36x
