Find y in terms of x for ln(y)=ln(x)+2

Answer:

First answer option:

"The first equation should be multiplied by 2 and the second equation by 3. "

Step-by-step explanation:

The first equation should be multiplied by 2 and the second equation by 3. This way the term in y in the first equation becomes "(2) (-3y) = -6y", and the term in y in the second equation becomes "(3) (2y) = 6y" so when added term by term, the term in "y" disappears.

That is represented by the first statement in your list of possible answers

Rotate it 90 degrees so that the would be the top.

Area of a trapezoid = (top+ bottom)/2 x height.

Each line on the graph is 2 units.

Top = 2

Bottom = 8

Height = 6

Area = (2+8)/2x6 = 30square units

Answer:

∠45°

Step-by-step explanation:

When looking at a unit circle, the only acute angle (an angle between

0° and 90°) that consists of an equal sine and cosine is 45°. This is because:

[tex]sin 45 = \frac{\sqrt{2} }{2}[/tex]

[tex]cos45 = \frac{\sqrt{2} }{2}[/tex]

45° is the only acute angle that contains an equal sine and cosine.

Answer:

45 degrees

Step-by-step explanation:

Since Sin(90-x) = Cos(x), we can find that the angle at which 90-x=x is 45 degrees. This corresponds to [tex]\frac{\pi }{4}[/tex] radians

Answer:

y+7= -6/5(x+3)

Step-by-step explanation:

Point slope form for a line is given by

y-y1 = m(x-x1) where m is the slope and (x1, y1) is a point on the line

y - -7 = -6/5(x - -3)

y+7= -6/5(x+3)

Answer:

Scalene

Answer:

(x-3)^2 + (y+2)^2 = 9^2

Step-by-step explanation:

x^2 -6x+y^2+4y-68 = 0

Complete the square

x^2 -6x+y^2+4y-68+68 = 0+68

x^2 -6x+y^2+4y = 68

Find the term to add for x

-6 /2 = -3  -3^2 = 9

Find the term to add for y

4/2 =2  2^2 = 4

Add 9 and 4

x^2 -6x+9+y^2+4y+4 = 68+9+4

(x-3)^2 + (y+2)^2 = 81

(x-3)^2 + (y+2)^2 = 9^2

The standard form is

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

Answer:

1.797 mm

Step-by-step explanation:

The key to solving this problem is finding the length of the coin wrapper, or "height" of the cylinder.

The volume of a cylinder equation is:

V = hπr^2

- We want to find h

- We are given diameter and we will want the radius so we divide

21.17/2 = 10.585

r = 10.585

So to find h we manipulate the equation by dividing both sides by pi and r^2

resulting in the following:

h = [tex]\frac{V}{\pi r^2}[/tex]

now substitute given values and we get

h = [tex]\frac{28470}{\pi10.585^{2} }[/tex] = 80.883

Now to find the thickness of a single coin we divide the length of the sleeve (h) by the number of coins in the sleeve (45).

Thickness = 80.883/45 = 1.797 mm

Answer:

The rectangle (A) has the largest area.

Step-by-step explanation:

To work out the area of the rectangle you have to multiply the width with the height.

A: 3 squares tall, and 5 squares wide. We have to multiply 3 with 5 which equals 15.

B: 2 squares tall, and 6 squares wide. We have to multiply 2 with 6 which equals 12.

The highest answer or area is 15. Which is Rectangle A.

Answer:

52°

Step-by-step explanation:

By remote interior angle theorem of a triangle:

115° = 63° + x° ( x is the vertical angle of one interior angle of the triangle)

x° = 115° - 63°

x° = 52°

x = 52

Answer:

120 miles is the answer

Answer:

Fatima's unit rate is 9.5 minutes per mile.

Step-by-step explanation:

To compute the one unit value of a variable divide the total values of n variables by n.

It is provided that it took Fatima 19 minutes to run 2 miles.

Then the unit rate at which Fatima runs is:

[tex]\text{Unit Rate}=\frac{19}{2}[/tex]

                [tex]=9.5[/tex]

Thus, Fatima's unit rate is 9.5 minutes per mile.

Answer:

120

Step-by-step explanation:

The sum of the degrees in any quadrilateral is 360. So add up all of the degrees you know and subtract it from 360 to get your answer.

120 + 60 + 60 = 240

360 - 240 = 120

another way you know that's easier is the angles that are diagonal are equal to one another, so since x is diagonal to 120, it is equal to 120.

Answer:

  B.  -1 ≤ y ≤ 1

Step-by-step explanation:

The range is the vertical extent of the function. Here, it appears the function is a sine function (y=sin(x)). The least value of the function is -1; the greatest value is +1. The function can take on any value between these extremes.

An appropriate description of the range is ...

  -1 ≤ y ≤ 1

Answer & Step-by-step explanation:

9x² + 6x + 12x + 8

First, simplify the expression.

9x² + 18x + 8

Now that you have simplified the expression, you can start factoring it. First, you have 9x². You can factor into 3x and 3x because 3 times 3 is 9 and once you multiply x by x, you will get x².

(3x + )(3x + )

Now that we have this part of the factoring, we have to find the other part. We can do this by looking at our constant number. Constant meaning a number that does not have a variable beside it. So, in this case, our constant is 8. We can reduce 8 into 2 and 4 because 2 times 4 is 8.

(3x + 2)(3x + 4)

So, the factored form of 9x² + 6x + 12x + 8 is (3x + 2)(3x + 4)

Answer: The lower quartile is 6

Step-by-step explanation: To find the lower quartile of a set of data, we can find the median of the data and then find the median of the first half. This strategy is similar to dividing a cake into halves, and then dividing one of the halves in half so that you end up with a quarter of the cake.

Answer:

<ABC = 30°

Step-by-step explanation:

<ABC + <CBD = 90 [Complementary angles add up to 90°]

x+7+2x+14 = 90

3x + 21 = 90

3x = 90-21

3x = 69

Dividing both sides by 3

x = 23

Now

<ABC = 23+7

<ABC = 30°

Answer:

30 degrees

Step-by-step explanation:

Answer:

Height: 48

Base: 34

Step-by-step explanation:

The formula for a triangle is 1/2(base)(height)

1/2(3x+10)(6x) = 816

18x² + 60x = 1632

18x² + 60x - 1632 = 0

Then, we use the Quadratic formula

x = (-60 ± √3600 + 117,504)/36

x =( -60 ± 348/36)

x = 288/36

x = 8

3(8) + 10

= 34

6(8) = 48

Therefore the dimensions are:

Height: 48

Base: 34

Answer:

Step-by-step explanation:

Using set notation to answer the question.

let n(U) be the total number of people surveyed = 1000

n(L) be number of people that visited London = 310

n(P) be number of people that visited Paris = 222

n(P∩L) be number of people that visited both cities = 118

n(P∪L)' be number of people that visited none of the cities = x

n(U) = n(PUL) + n(PUL)'

We willl get n(PUL) using the formula;

n(PUL) = n(P)+ n(L)-n(P∩L)

n(PUL)= 222+310-118

n(PUL)= 414

Since n(U) = n(PUL) + n(PUL)'

1000 = 414+n(PUL)'

n(PUL)' = 1000-414

n(PUL)' = 586

586 peoples visitied none of these cities?
