Answer:

0.7

Step-by-step explanation:

The function's range is in the interval (1, ∞).

Members of a set can congregate in mathematics.

These sets' constituents are referred to as elements. The correspondence between the two groups is known as a relation when the elements of each group are paired up together.

So, between two sets, a relation is a collection of ordered pairs of elements.

The term "function" refers to a particular type of relation where each element in the first group, referred to as the domain, corresponds to exactly one element in the second group, referred to as the range.

The elements in the domain couple with exactly one element in the range, and this is how a function is a pairing between two sets.

According to our question-

[7, ] is the interval notation.

The function's range falls between the numbers (1, ).

provided function

Determine the function's domain:

You do not want to use a counterargument to the square root in this situation (you cannot find the solution of a negative square root, at least as a real number).

What you actually do is "impose" that the argument always ends in a yes or a no (you know the square root of a positive number or zero).

You then solve for x to determine the variable's ALLOWED values by setting the argument greater than or equal to zero:

Consequently, the function is in the domain.

The given expression is simplified as -4/7. So, the correct option is D.

To simply means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue.

Given that, (8-(4)(3))/(∛8 +5).

The given expression can be simplified as follows

Numerator of fraction simplified as 8-(4)(3)

= 8-12

= -4

Numerator of fraction simplified as (∛8 +5)

We know that, cube root of 8 (∛8) is 2

=(2 +5)

= 7

Thus, the fraction is -4/7

So, the expression (8-(4)(3))/(∛8 +5) is reduced to -4/7.

The simplified form of expression is -4/7. Therefore, option D is the correct answer.

Because the value of x is 126° and the value of cos 2x is -0.301, which is fractionally identical to -7/25, the value of cos 2x will be -7/25.

Trigonometry is the study of angles and the angular relationships between planar and three-dimensional shapes. The cosecant, cosine, cotangent, secant, sine, and tangent are among the trigonometric functions (also known as the circle functions) that make up trigonometry. The sine, cosine, and tangent are the three fundamental trigonometric operations. The cotangent, secant, and cosecant functions are derived from these three basic functions. On these functions, all trigonometrical concepts are built.

Here,

sin x=4/5

x=126°

Cos 126°=-0.588

cos (2*126)=-0.310

The value of cos 2x will be -7/25 because value of x is 126° and that of cos 2x is -0.301 that is fractionally equal to -7/25.

Answer:

6 drinks

2 boxes of candy

==================================================

Explanation:

x = number of drinks

y = number of boxes of candy

These two variables represent positive integers.

"He bought 3 times as many drinks as candies" which means we can set up the equation x = 3y

-------------

1 drink costs $4.50

x drinks cost 4.50x dollars

1 box of candy costs $3

y boxes of candy cost 3y dollars.

4.50x + 3y = total cost = 33 dollars

Therefore, we arrive at the second equation of 4.50x+3y = 33

-------------

We have this system of equations

[tex]\begin{cases}x = 3y\\4.50x+3y = 33\end{cases}[/tex]

I'll use substitution to solve. Replace x with 3y in the second equation, then isolate y.

[tex]4.50x+3y = 33\\\\4.50(3y)+3y = 33\\\\13.50y+3y = 33\\\\16.50y = 33\\\\y = 33/16.50\\\\y = 2\\\\[/tex]

This tells us he bought 2 boxes of candy.

Use that value to find x.

[tex]x = 3y\\\\x = 3*2\\\\x = 6\\\\[/tex]

Carter also bought 6 drinks.

-------------------------------

Check:

The answers are confirmed.

Another way to confirm the answers is to plug (x,y) = (6,2) into each equation of the system I mentioned earlier. After simplifying, you should get the same thing on both sides.

A visual way to confirm the answers is to graph each equation on the same xy grid. The two lines intersect at (6,2). You can use a graphing tool such as Desmos or GeoGebra.

The values of given functions are Sin2x = 120/169, Cos2x = 119/169 and tan2x = 120/119.

Trigonometric equation is a condition including at least one trigonometric ratios of obscure points. It is communicated as proportions of sine(sin), cosine(cos), tangent(tan), cotangent(cot), secant(sec), cosecant(cosec) points. For instance, cos2 x + 5 sin x = 0 is a mathematical condition.

We have,

Cosx = 12/13

Use sin^2(x) + Cos^2(x) = 1

sinx = [tex]\sqrt{1-cos^{2}x}[/tex] = 5/13

We know that

Sin2x = 2sinxcosx

Sin2x = 2(5/13)(12/13)

Sin2x = 120/169

Using cos2x = 2cos^2x - 1

cos2x = 2(12/13)^2 - 1

Cos2x = 119/169

Then, using tanx = sinx/cosx

tan2x = sin2x/cos2x

tan2x = [tex]\frac{\frac{120}{169} }{\frac{119}{169} }[/tex] = 120/119

Thus, required values Sin2x = 120/169, Cos2x = 119/169 and tan2x = 120/119

Increasing the given sample size will decreases the probability because σx will decreases as n value increases.

In Statistitics whenever we test a hypothesis for testing a statistic, we use confidence interval. Confidence interval is on either side of an assumed value a margin of error. Margin of error is calculated as critical value * sigma/sqrt of n. Thus we find that whenever n increases, margin of error decreases.

Thus making confidence interval narrower and thus making probability for accepting null hypothesis a less value. As the pattern sizes increase, the range of every sampling distribution decreases so they emerge as more and more leptokurtic. The variety of the sampling distribution is smaller than the variety of the authentic populace. Therefore, as a pattern length increases, the pattern imply and general deviation might be nearer in fee to the populace imply μ and general deviation σ.

Answer:

see explanation

Step-by-step explanation:

vertical angles are congruent , then

2x - 3 = x + 16 ( subtract x from both sides )

x - 3 = 16 ( add 3 to both sides )

x = 19

Then

x + 16 = 19 + 16 = 35°

since the angles are congruent , then

the measure of each angle is 35°

Step-by-step explanation:

Formula 1: V = lwh

V = 10 x 8 x 6

V = 480

Formula 2: V = 2lw + 2lh + 2wh

V = 2(10 x 8) + 2(10 x 6) + 2(8 x 6)

V = 480

To find the value of K, we need to find the point at which the line Y=2x+K is tangent to the parabola Y=x^2-4x+4. This means that the line and the parabola will have the same y-value at this point, and the line will be tangent to the parabola (meaning it will just touch the parabola at this point, without intersecting it).

To find the point at which the line and parabola are tangent, we can set Y=2x+K equal to Y=x^2-4x+4 and solve for x:

2x + K = x^2 - 4x + 4

x^2 - 4x + 4 - 2x - K = 0

(x-2)^2 = K

x = 2 +/- sqrt(K)

Since the line is tangent to the parabola, it will just touch the parabola at this point, which means that the parabola will have a minimum value at this point. This means that the value of K must be nonnegative, because the square root of a negative number is not a real number. Therefore, K must be equal to or greater than 0.

So, the value of K for which Y=2x+K is tangent to Y=x^2-4x+4 is K >= 0.

Answer:

Each egg costs $0.60

Each piece of toast costs $0.30

Step-by-step explanation:

Let's assume that the cost of a single egg is E

And the price of a toast as T

Kendra charges $1.50 for one toast and two eggs

The equation above will be

2E + T = $1.50

And the other equation is

E + T = $0.90

For the second equation, we make E the subject of the formula

E = 0.90 - T

Now substitute for this in equation 1

2E + T = 1.50

It will now be 2(0.90 - T) + T = 1.50

1.80 - 2T + T = 1.50

T= $0.30

price of one toast is $0.30

And now, for the price of an egg, we substitute T = 0.30 in the equation

E= $0.60
