Answer:

ln(25x)

Step-by-step explanation:

ln(x) + 2ln(5)+ln(1) = ln(x) + ln(5^2) + ln(1)

= ln(x*5^2*1) = ln(25x)

Answer:

75 posters

Step-by-step explanation:

Given

[tex]y = 3x[/tex] ----  Revenue

[tex]y = \frac{x}{3} + 200[/tex] --Cost of production

Required

Determine the number of posters that when cost equals revenue

To do this, we simply equate both equations

i.e. [tex]3x = \frac{x}{3} + 200[/tex]

Collect like terms.

[tex]3x - \frac{x}{3} = 200[/tex]

Multiply through by 3

[tex]3(3x - \frac{x}{3}) = 200*3[/tex]

[tex]9x - x = 600[/tex]

[tex]8x = 600[/tex]

Divide both sides by 8

[tex]\frac{8x}{8} = \frac{600}{8}[/tex]

[tex]x = \frac{600}{8}[/tex]

[tex]x = 75[/tex]

Answer:

y = x - 2

Step-by-step explanation:

Slope intercept form is: y = mx + b, where m is the slope and b is the y- intercept. In this question, we are given everything, and all we need to do is rearrange the terms.

-x + y = -2

Add x to both sides

y = x - 2

In this equation, the slope is 1 and the y intercept is -2.

Answer:

Step-by-step explanation:

Y = mx + b

Y = x -2 after adding x to both sides of equation

m = 1 and b = -2

Answer:

x=34 degrees

Step-by-step explanation:

since angle TSU=4x then angle RSP=4x

4x-3x=x

angle PSQ=x

angle PQS=112 degrees (180-68=112)

triangle PSQ angles are x+x+112=180

2x-68

x=34 degrees

Given that,

The vertices of a rectangle are (–1, 1), (3, 1), (–1, –4), and (3, –4).

To find,

The perimeter of the rectangle.

Solution,

Let the points are :

A(–1, 1), B(3, 1), C(3, –4) and D(–1, –4)

Let's find AB and BC using distance formula :

[tex]AB=\sqrt{(3-(-1))^2+(1-1)^2} \\\\=4\ \text{units}[/tex]

[tex]BC=\sqrt{(3-3)^2+(-4-1)^2} \\\\=5\ \text{units}[/tex]

The perimeter of a rectangle = 2(sum of two adjacent sides)

= 2(AB+BC)

= 2(4+5)

= 18 units

So, the perimeter of the rectangle is 18 units.

Answer:

[tex]y = \frac{-3}{2}x - 14[/tex]

Step-by-step explanation:

(-4 , -8)  ;  slope = (-3/2)

Equation of the line: y - y₁ = m( x- x₁)

[tex]y - [-8] = \frac{-3}{2}(x - [-4])\\\\y + 8 = \frac{-3}{2}(x +4)\\\\y + 8 = \frac{-3}{2}x +(\frac{-3}{2})*4\\\\y + 8 = \frac{-3}{2}x - 3 * 2\\\\ y = \frac{-3}{2}x -6 -8\\\\y = \frac{-3}{2}x - 14[/tex]

Step-by-step explanation:

The place-value chart's two tenths closest to 0.446 is 0.4. We can determine the place value of each digit based on its location in a number using the place value chart, which is a very useful table structure.

The place value chart is a very helpful table structure that enables us to determine each digit's place value based on where it is in a number. On the place value chart, a digit's place value increases as we move left and drops as we move right by a factor of ten.

Using a place value chart, we may compare the place values of the digits in a number and determine a digit's exact position. In this graph or figure, the place value of a number's digits increases as we move to the left and drops as we move to the right.

Given

0.446

In ones place is 0

In tens place is 4

In hundredth place is 4

In thousand place is 6

Therefore, The place-value chart's two tenths closest to 0.446 is 0.4.

Answer:

24

Step-by-step explanation:

Imagine s is 1, no is 2, wm is 3, and an is 4.

If you look at all the possible ways to orginaze the numbers starting with one you get 6;

1234

1243

1324

1342

1432

1423

you then need to multiply this by the amount of numbers that could be in the start; which is four; 1, 2, 3, and 4. So, six ways to orginaze multiplied by 4 numbers is 24.

In Snowman language, total words are 24.

Permutation and combination are ways to arrange values in a set. In permutation the order of arrangement matters, but in combination the order of arrangement does not matter,

Given that,

Total number of letters in Snowman language = 7

The letters are in form of {s, no, wm, an}.

To find the total words in Snowman language,

Consider the following: s = 1, no = 2, wm = 3, and an = 4.

If you consider every possible method to order the numbers beginning with one, you will arrive at the number 6;

1234

1243

1324

1342

1432

1423

You must then multiply this by the total number of possible numbers at the beginning, which is four: 1, 2, 3, and 4. Six possible organizations divided by four digits equals 24.

So, the total words in Snowman language is 24.
