what is the solution of in(x-2)^2=6

Answers

Answer:

22.09

Step-by-step explanation:

Given the expression ln(x-2)^2=6

Take exponent of both sides

e^ln(x-2)^2=e^6

(x-2)² = e^6

(x-2)² = 403.43

x - 2 = √403.43

x - 2= 20.09

x = 20.09 + 2

x = 22.09

Hence the value of x is 22.09

Can some solve this and explain how they solved it for both process

Answer:

1=27 2= -1

Step-by-step explanation:

if three watermelons equal 60 divide that by 3 to get 20. 30 minus 20 will get you what the strawberries together make so divide by two to get 5. After subtract 5 from 3 to get -2 and since you did it in reverse think of it as a positive. So that equals 1. 20 + 1 + 7 is 27. For number two start at the bottom with the clovers since its only clovers.divide 12 by 3 to get 4. Then go up to the second equation 31-16 is 15. After divide by 3 and get 5. Then go to the next equation and do the same thing, add the sunflowers and then subtract the sum from both sides. 40 - 10 is 30. 30 divided by 3 is ten. After go to the last one. 5 - 10 + 4 is -1.

¿Cómo expresarías la siguiente cantidad 1149,8x1018, en su equivalencia a notación científica?

Answers

Respuesta:
hay tres respuesta creo en el problema te los dire los tres:
Primero tu pregunta:
Cómo corregirías esta equivalencia?
1149,8 x 10¹⁸ = 1,15 x 10¹⁸
Recordemos:
-en la notacion cientifica no se aproxima, solo se reduce
-Requisito: La notacion cientifica debe estar dentro de los estandares de 1-10
sabiendo esp te dare un ejemplo y asi se te hace mas faci:
1149,8 x 10¹⁸ = 1,15 x 10¹⁸ esta es mal
1149,8 x 10¹⁸ = 114,98 x 10¹⁸ + 1 ( esto se suma xq se movio la coma a la derecha)
PSDT: esta sumando el exponente ese pequeño(yo no puedo ponerlo pequeño xd)
Bueno segun esto avanzamos hasta que cumpla el requisito
y quedaria asi:
1149,8 x 10¹⁸ esta es la forma mala
asi quedaria: 1,1498 x 10 sobre 21 ( arribita del 10 va 21)
Que procedimientos ayudaron a encontrar la respuesta?

Explicación paso a paso:

You raise pigs. When you purchase the pig it weighs 54 pounds. Within 5 to 6 months your pig will gain around 420% in weight. How much should it weigh by then?

Answers

Answer:

280.8 pounds

Step-by-step explanation:

Original weight of pig = 54 pounds

Percentage increase in weight = 420%

Current weight of pig = original weight + 420% of original weight

= 54 + 420% of 54

= 54 + 420/100 * 54

= 54 + 4.2 * 54

= 54 + 226.8

= 280.8 pounds

Current weight of pig = 280.8 pounds

FIND THE AREA OF THE SHADED REGION​

Answers

Answer:

A =28 pi cm^2

Step-by-step explanation:

First find the area of the larger circle

A = pi r^2

A = pi (8)^2

A = 64 pi

Find the area of the smaller circle

A = pi r^2

A = pi 6^2

A = 36 pi

The shaded area is the larger circle minus the smaller circle

A shaded = 64 pi - 36 pi

A =28 pi cm^2

28 pi is the correct answer. Subtract the larger area which is 64 pi by the smaller which is 36 pi and you get 28 pi

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = [tex]\frac{1}{2}[/tex] x + 4 ( multiply through by 2 to clear the fraction )

2y = x + 8 ( subtract 8 from both sides )

2y - 8 = x

Change y back into terms of x with x = [tex]f^{-1}[/tex] (x) , then

The larger triangle is twice as big as the smaller triangle. Therefore, the length of the side EF is twice as large as the side YZ.

I multiplied 4.5 (the length of YZ) and 2 to get 9. The value of side EF is 3x-12 and should be equivalent to 9.

3x - 12 = 9

I solved this equation by adding 12 to both sides and dividing 3 on both sides.

Write an equation that represents the line

Answers

Answer:

y = -2x - 3

Step-by-step explanation:

A standard equation written in slope-intercept form looks like this:

y = mx + b

m is the slope and b is the y-intercept.

First let's identify the y-intercept.

This is the point where the line crosses the y-axis. That point is (0, -3); therefore, our y-intercept is -3.

y = mx - 3

Now let's find the slope.

This is the rate of change of the line. It is represented by rise over run. "Over" means the number will be presented as a fraction.

We can see that from Point 2 (on the right), we rise 2 units to the level of Point 1 (on the left). This is expressed as 2.

To get directly to Point 1, we run backwards 1 unit. This is expressed as -1.

rise: 2

run: -1

rise/run = 2/-1 = -2

-2 is our slope.

y = -2x - 3

This is your equation.

Hope this helps!

Answer:

Step-by-step explanation:

for part a:

since all sides are the same length (represented by the 3 same type of tick marks on all sides) then the triangle is equilaterial. Which means all the angles are the same.

Sum of angles in a triangle is 180˚.

x represents the value of <N, <M, and <P

so since all angles are the same, 3x = 180, all angles of part a triangle are 60˚. Therefore, <M is 60˚.

for part b:

this is an isoceles triangle since two sides are the same length.

If it's isoceles, that means it's 2 base angles are the same value.
