Writing the given trigonometry expression: cos(2 tan inverse (x)) as algebraic expression gives

How to write given expression: cos(2 tan inverse (x)) as algebraic expression

Data given in the question are as follows:

cos(2 tan inverse (x))

Using trigonometry (double angle formula)

cos 2x = 1 - 2sin² x

when x = tan inverse (x)

cos(2 tan inverse (x))  = 1 - 2sin² tan inverse (x)        (1)

cos² x + sin² x = 1

cos² x = 1 - sin² x

cos x = √(1 - sin x)

tan x = sin x / cos x

[tex]tan x = \frac{sinx }{\sqrt{1-sin^{2}x } }[/tex]

Geometry ?Use the photo to help me solveTriangle DEF is shown. What is the coordinate of D if triangle D E F is created by dilating DEF with a scale of 0.5 about the origin

Answers

Explanation

Since the scaling factor of the dilation (0.5) is fewer than 1, it shrinks (make smaller) the triangle around the origin (zero). Intuitively, the dilation is getting the points of the triangle closer to zero (in a way that preserves the shape of the triangle).

Formally, to know the coordinates of a point of the triangle after the dilation, we just need to multiply the original coordinates of the point by the scaling factor (this works for the dilation is around zero).

The original coordinates of D are

Answers

Whereas working with laws of exponents, when splitting the exponential equations with the same base, the exponents ought to be subtracted.

Basically, the Quotient of Powers rules is used to decrease the number of terms when parts like terms with exponents. In order to get the solution, just remove the exponents while dividing the terms with the same base, it is applicable to exponents with the same bases. when powers are multiplied,  for two whole numbers of the same bases the exponents are added, whereas when powers are divided for two whole numbers of the same bases,  exponents are subtracted. The zero exponent rule basically states that when any number is raised to the power of zero it results in 1.

One month Tony rented 5 movies and 3 video games for a total of $32. The next month he rented 2 movies and 12 video games for a total of $83. Find therental cost for each movie and each video game.Rental cost for each movie:Rental cost for each video game:

Answers

Let x represent the rental cost for each movie.

Let y represent the rental cost for each video game.

We were told that One month Tony rented 5 movies and 3 video games for a total of 532. This means that

5x + 3y = 32

Also, the month, he rented 2 movies and 12 video games for a total of $83. This means that

2x + 12y = 83

Dividing through by 2, we have

x + 6y = 41.5

x = 41.5 - 6y

Substituting x = 41.5 - 6y into 5x + 3y = 532, we have

5(41.5 - 6y) + 3y = 32

207.5 - 30y + 3y = 32

- 30y + 3y = 32 - 207.5

- 27y = - 175.5

y = - 175.5/- 27

y = 6.5

x = 41.5 - 6(6.5) = 41.5 - 39

x = 2.5

Rental cost for each movie = $2.5

Rental cost for each video game = $6.5

fill in the missing numbers along the sides of the triangle so that it contains each of the numbers from 4 through 12 exactly once. furthermore each side of the triangle should contain four numbers whose sum is 32the pair of numbers that can be used for A and B is ___. the pair of numbers that can be used for C and D is ____. and the pair of numbers that can be used for E and F is___.

Answers

Answer:

For A and B, we have (10, 6)

For C and D, we have (12, 8)

For E and F, we have (12, 8)

Explanation:

To determine the missing numbers along each side of the triangle, we have to

*Add the two numbers at the vertex

*Subtract it from 32

*Divide it by 2

*Add 2 to it to have the 1st number

*Subtract 2 from it to have the 2nd number

So to find the pair of numbers that can be used for A and B, we'll have;

[tex]\begin{gathered} 12+4=16 \\ 32-16=16 \\ \frac{16}{2}=8 \\ 8+2=10 \\ 8-2=6 \end{gathered}[/tex]

Therefore the missing numbers for A and B are 10 and 6.

So to find the pair of numbers that can be used for C and D, we'll have;

[tex]\begin{gathered} 4+8=12 \\ 32-12=20 \\ \frac{20}{2}=10 \\ 10+2=12 \\ 10-2=8 \end{gathered}[/tex]

Therefore the missing numbers for C and D are 12 and 8.

So to find the pair of numbers that can be used for E and F, we'll have;

[tex]\begin{gathered} 12+8=20 \\ 32-20=12 \\ \frac{12}{2}=6 \\ 6+1=7 \\ 6-1=5 \end{gathered}[/tex]

So to avoid repetition of any of the numbers between 4 and 12, we have to add and subtract 1 instead of 2.

Two trains leave the same station at the same time, one traveling west at a constant speed of 60 miles per hour, the other traveling south at a constant speed of 80 miles per hour. After how long are the two trains exactly 300 miles apart?

Answers

After 2.14 hours the trains are exactly 300 miles apart.  

How to find the time the trains travel 300 miles apart?

Two trains leave the same station at the same time, one traveling west at a constant speed of 60 miles per hour, the other traveling south at a constant speed of 80 miles per hour.

The time both of them will travel 300 miles can be calculated as follows:

Therefore,

speed = distance / time

distance = speed × time

The train that travel west:

let

t = time of the train that travel west

distance = 60t

The train that travel south:

distance = 80t

Therefore,

total distance = 60t + 80t

300 = 140t

t = 300 / 140

t = 2.14285714286

t = 2.14 hours

Therefore,

time taken  = 2.14 hours

Write the equation of the line with the given information in point-slope form. (-5, 11) and (-2, 1)

Answers

Answer

The equation in point-slope form is

y - 1 = (-10/3) (x + 2)

We can then simplify this by multiplying through by 3 to obtain

3y - 3 = (-10) (x + 2)

3y - 3 = 10x - 20

3y = 10x - 20 + 3

3y = 10x - 17

Explanation

The general form of the equation in point-slope form is

y - y₁ = m (x - x₁)

where

y = y-coordinate of a point on the line.

y₁ = This refers to the y-coordinate of a given point on the line

m = slope of the line.

x = x-coordinate of the point on the line whose y-coordinate is y.

x₁ = x-coordinate of the given point on the line

We can calculate the slope of the line and then use any of the two points given to serve as the point (x₁, y₁) in the equation

For a straight line, the slope of the line can be obtained when the coordinates of two points on the line are known. If the coordinates are (x₁, y₁) and (x₂, y₂), the slope is given as

[tex]Slope=m=\frac{Change\text{ in y}}{Change\text{ in x}}=\frac{y_2-y_1}{x_2-x_1}[/tex]

For this question,

(x₁, y₁) and (x₂, y₂) are (-5, 11) and (-2, 1)

x₁ = -5

y₁ = 11

x₂ = -2

y₂ = 1

[tex]\text{Slope = }\frac{1-11}{-2-(-5)}=\frac{-10}{-2+5}=\frac{-10}{3}[/tex]

Slope = m = (-10/3)

Using the point (-2, 1) as (x₁, y₁), we can write the equation of the line

y - y₁ = m (x - x₁)

y - 1 = (-10/3) (x - (-2))

y - 1 = (-10/3) (x + 2)

We can then simplify this by multiplying through by 3 to obtain

3y - 3 = (-10) (x + 2)

3y - 3 = 10x - 20

3y = 10x - 20 + 3

3y = 10x - 17

find an equation of the circle that has center (1,-5) and passes through (2,1)

Answers

[tex](x-1)^2+(y+5)^2=37[/tex]

1) Since the equation of the circle is given by:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

And we've been told the Center (1,-5) and one point located at the circumference, (2,1). So let's find the radius, i.e. the distance from the center to any point to the circumference.

2) Let's use the Formula for the distance between (1,-5) and (2,1), derived from the Pythagorean Theorem:

[tex]\begin{gathered} d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2} \\ d=\sqrt[]{(2-1)^2+(1_{}+5)^2} \\ d=\sqrt[]{37} \end{gathered}[/tex]

3) So d = radius, and now we can plug those pieces of information into the formula of the circle:

[tex]\begin{gathered} (x-h)^2+(y-k)^2=r^2 \\ (x-1)^2+(y+5)^2=(\sqrt[]{37})^2 \\ (x-1)^2+(y+5)^2=37 \end{gathered}[/tex]

So we now have the formula for that circle.

Answer:

Radius (R) is equal to the distance between the points (-2,1) and (3,1)

R² = (1 - 5)² + (1 - 1)² = (-24)² + 0 = 579

R =  23.16

⇒ 5( y - 3) = (x + 6)

⇒ 5y - 15 = x + 6

Add 15 both side, we get;

⇒ 5y - 15 + 15 = x + 6 + 15

⇒ 5y = x + 21

Subtract 21 both side, we get;

⇒ 5y - 21 = x + 21 - 21

⇒ 5y - 21 = x

Subtract 5y both side, we get;

⇒ 5y - 21 - 5y = x - 5y

⇒ - 21 = x - 5y

⇒ x - 5y = -21

Therefore,

The Standard form of the equation will be;

a=460 rounded to the nearest 10 b=11.9 rounded to 1 dp find the minimum (to 2 dp) of a / b

Answers

The minimum result (to 2 dp) of a / b is 38.66

What is rounding decimals?The term "rounding decimals" refers to the accurate rounding of decimal figures. When rounding a decimal number, certain principles must be followed. Simply put, if the last digit is less than 5, round down the previous digit. However, if it is 5 or greater, round the previous digit up.

Given:

a=460 rounded to the nearest 10

b=11.9

Now, substitute the values of a and b in a/b,

a/b = 460/11.9

Multiply the same integer(10) by both the numerator and denominator,

a/b = 4600/119

Round the number obtained

a/b ≅ 38.66

GIVING 20 POINTS! ENGLISH!There never was a time when the world was without fire, but there was a time when men did not know how to kindle fire; and after they learned how to kindle one, it was a long, long time before they learned how to kindle one easily. In these days we can kindle a fire without any trouble, because we can easily get a match; but we must remember that the match is one of the most wonderful things in the world, and that it took men thousands of years to learn how to make one. Let us learn the history of this familiar little object, the match.Fire was first given to man by nature itself. When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by natureby a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar.Which of the following is the best paraphrase of the first paragraph?A. Fire often comes from nature, like from a volcano or lightening striking a tree. Before humans could create their own fire, it only came from nature. Humans first got their own fire by lighting sticks of wood from where nature caused a fire. People guarded the fires to keep them from going out, except that sometimes, it would go out. Wind or rain would put out the fire and then they would have to find more fire.B. In 1827, a man named John Walker came up with a formula of friction (sandpaper) and chemicals (sulphur, chlorate of potash, and sulphid of antimony) to create the very first match. It didn't work incredibly well, as it needed a very hard strike and fire got everywhere, so he changed his formula later. Matches now needed less pressure and different chemicals and didn't need to be struck on sandpaper. These are the phosphorus matches that we still use today.C. It took humans a long time to be able to create fire on their own. The invention of matches is amazing to learn about. D.The earth has always had fire, but humans didn't know how to make it themselves. After they finally learned, it was hard for them for a while. Today, it's easy because we can just get a match, but matches are amazing. It took humans many years to learn to make matches, so let's examine the history of the ma Which ideas describe the big crunch?
