Answer:

Sqrt(7) is irrational because 7 is not a perfect square.

7.1234... is irrational because it is a nonterminating nonrepeating decimal.

Step-by-step explanation:

A rational number is a number that can be expressed in terms of fractions which result in terminating decimals, repeating decimals, or integer values.

An irrational number is a number that cannot be expressed in terms of fractions resulting in nonrepreating nonterminating decimals.

All options other than the two selected do not make sense.  Pi is irrational because it is a nonrepeating nonterminating decimal.

12) Twenty cubic feet of marble can weigh 3400 pounds, plus or minus 100

pounds. Write and solve an absolute-value inequality for the possible weights of a

cubic foot of marble.

Answers

Answer:

Let's suppose that one cubic foot of marble is x.

20x = 3400

But because the weight has a range of +-100, then 20x is between 3300 and 3500. Write it like this:

3300<20x<3500

Divide by 20:

165<x<175

The meaning of this is that one cubic foot of marble weight between 165 and 175 pounds

The obtained inequality shows that one cubic foot of marble weight between 165 and 175 pounds.

Given that, twenty cubic feet of marble can weigh 3400 pounds, plus or minus 100 pounds.

What is an absolute-value inequality?

Absolute value inequalities are inequalities in algebra that involve algebraic expressions with absolute value symbols and inequality symbols. In simple words, we can say that an absolute value inequality is an inequality with an absolute value symbol in it. It can be solved using two methods of either the number line or the formulas. An absolute value inequality is a simple linear expression in one variable and has symbols such as >, <, ≥, ≤.

Now, the weight has a range of ±100, then 20x is between 3300 and 3500.

That is, 3300<20x<3500

Divide the inequality by 20.

So, 165<x<175

Therefore, the obtained inequality shows that one cubic foot of marble weight between 165 and 175 pounds.

Imagine a population of 100 individuals, with the initial frequencies A1 = 0.7 and A2 = 0.3. If A1 and A2 are selectively neutral what is the probability that the A2 allele will drift to fixation?
a. 70%
b. 30%
c. 3%
d. 0

Answers

Answer: b. 30%

Step-by-step explanation:

given data:

population size (n) = 100

A1 = 0.7

A2 = 0.3

if A1 and A2 are selectively neutral, the probability that A2 would drift to fixation

= 0.3

= 30%

there is a. 30% chance that A2 would drift towards fixation.

Answer:

x = -2

Step-by-step explanation:

First distribute the 2 with x and 3

Equation should look like... 2x + 6 - 10 = 4x

Second combine like terms, 6 and -10

Equation should look like... 2x - 4 = 4x

Third bring 2x to the other side making it -2x and subtract it from 4x

Equation should look like... -4 = 2x

Last divide -4 and 2.

Equation should look like... x = -2

If g(x)=x^2+5x find the value g(-2)+2

Answers

Answer:

-4

Step-by-step explanation:

g(-2) =  (-2)^2 + 5(-2)

g(-2) = 4 - 10

g(-2) = -6

and

g(-2) + 2

-6 + 2 = -4

Answer:

-4

Step-by-step explanation:

g(x)=x^2+5x

First find g(-2) by letting x=-2

g(-2) = (-2)^2 +5(-2)

       = 4 -10

      = -6

g(-2) +2 = -6+2 = -4

f(x) = 2x – 1 What is f(13)?

Answers

Answer:

f(13) = 25

Step-by-step explanation:

f(x) = 2x – 1

To find f(13) substitute the value of x that's 13 into f(x). That is for every x in f (x) replace it with 13

We have

f(13) = 2(13) - 1

= 26 - 1

We have the final answer as

f(13) = 25

Answer:

Add like terms

Step-by-step explanation:

You want to combine the squared, the variables, and the constants.

Combine -2x^2 and 7x^2 to get 5x^2

Then combine 8x and 4x which is 12x

Then combine -9 and +2 which is -7.

You should get 5x^2 + 12x - 7.

Keep in mind you can only combine like terms that are in the same equals barrier

For example: You can combine 8x + 3 + 2x = 0

but not 8x +3 = 2x +0 because they are on different sides of the equal sign.

which number can each term of the equation be multiplied by to eliminate the fractions before solving?
