Which is the solution of x=2+√x-2? <br>x=2 <br>x=3 <br>x=2 or x=3 <br>no solution​
erik [133]
No Solution
x=2+ Square root of x-2
-2
x-2= Square root of x-2
2s cancel out.
x = Square root of x
Or you can just graph it and see no solutions

Do you agree with the researchers method of predicting the population? Why or why not?
Burka [1]

Yes, I agree with the researcher's method. All the values of a_{n} in the table correspond to the values of n by using their formula.

Step-by-step explanation:

Step 1:

If we substitute the values of n in the researcher's equation and we get the right values of a_{n}, we can agree with the researcher's method.

The researcher's formula is a_{n} = 1000(2)^{n-1}. Here a_{n} is the wombat population and n is the number of years.

Step 2:

When n = 1, a_{1} = 1000(2)^{1-1} =  1000(1) = 1,000,

when n = 2, a_{2} = 1000(2)^{2-1} = 1000(2) = 2,000,

when n = 3, a_{3} = 1000(2)^{3-1} = 1000(4) = 4,000,

when n = 4, a_{4} = 1000(2)^{4-1} = 1000(8) = 8,000,

when n = 5, a_{5} = 1000(2)^{5-1} = 1000(16) = 16,000.

As all the values correspond to the values on the table, I agree with the researcher's method.

wendy is logging the number of video game levels she wins per hour. she has determined the function to be f(x) = 6x + 9, where x
True [87]
Since we are talking about real quantities (hours), x should be positive. Also, you need to take into account that Wendy needs to play in order to win game levels.
Therefore the domain will be: x > 0

In a bag of candy, Marsha found that there were 7 red, 8 blue, 5 yellow, and 9 greens pieces of candy. Marsha put all of the pie
son4ous [18]

Answer:

Step-by-step explanation:

1) find the total candies

7 + 8 + 5 + 9 = 29

2) a probability can be expressed with a fraction whose denominator is the total candies, while the numerator represents the candies that we want to find

- red = 7/29

- blue = 8/29

- yellow = 5/29

- green = 9/29

3) compound probability

(red + blue)/29 = 15/29

(yellow + green)/29 = 14/29

(blue + yellow + green)/29 = 22/29

6. (5 points) What is 3loga + logb − logc written as a single logarithm?
Jobisdone [24]

Answer: log(\frac{a^3b}{c})

Step-by-step explanation:

You need to use the following Properties of Logarithms:

1)m*log(a)=log(a)^m\\\\2)log(a)+log(b)=log(ab)\\\\3)log(a)-log(b)=log(\frac{a}{b})

Given the following expression:

3log(a) + log(b) - log(c)

You can follow these steps in order to write it as a single logarightm:

- Apply the first property shown above:

=log(a)^3 + log(b) - log(c)

- Apply the second property:

=log(a^3b)- log(c)

- Finally, apply the third property:

=log(\frac{a^3b}{c})
