Answer:

E. 2/5 a³

Step-by-step explanation:

$\sqrt{36a^8/225a^2} =$ simplify
$\sqrt{4a^6/25} =$ square root
2/5 a³

Also possible option is B if 4a⁶/25 is under root

Step-by-step explanation:

√(36a⁸/225a²)

=> 6/9√(a⁸/a²)

If option B is 6/25√(a⁸/a²)

Otherwise

=> √(36a⁸/225a²)

=> √(36a⁶/225)

=> 6a³/15

=> 2/5a³

To finance her community college education, Sarah takes out a loan for $3700. After a year Sarah decides to pay off the inter

iragen [17]

So, to solve this, we use this equation:
3700 + 0.05(3700)
But, if we want to make it shorter:
1.05(3700)
Now you just multiply(you may want to use a calculator)
1.05(3700) = 3885
She will pay $3885

X=y<br> x+2y =3<br> Solve using substitution

Zielflug [23.3K]

Answer:

Therefore the Final Solution is

x = 1 and y = 1

Step-by-step explanation:

Given:

$x=y$ ...............Equation ( 1 )

$x+2y=3$ ................Equation ( 2 )

To Find:

x = ?

y = ?

Solution:

Equating Equation ( 1 ) in Equation ( 2 ) we get

$y+2y=3\\\\3y=3\\\\y=\frac{3}{3} \\\\\therefore y =1$

Now Substituting y = 1 in Equation ( 1 ) we get

$x =1\\\\\therefore x=1$

Therefore the Final Solution is

x = 1 and y = 1

PLEASE HELP!! A classmate wrote the set notation for the values of the domain of a function {−5, −4, −3, −2, −1, 0} as {x | −5 ≤

vfiekz [6]

<h3>Answer: Choice B</h3>

The set notation includes all values from -5 to 0, but the domain only includes the integer values

eg: something like -1.2 is in the second set, but it is not in the set {-5,-4,-3,-2,-1}

==========================================================

Further explanation:

Let's go through the answer choices one by one

A. This is false because 0 does not come before -5, but instead -5 is listed first. The order -5,-4,-3,-2,-1,0 is correct meaning that $-5 \le x \le 0$ is the correct order as well.
B. This is true. A value like x = -1.2 is in the set $\left\{x| -5 \le x \le 0\right\}$ since -1.2 is between -5 and 0; but -1.2 is not in the set {-5, -4, -3, -2, -1, 0}. So the distinction is that we're either considering integers only or all real numbers in this interval. To ensure that we only look at integers, the student would have to write $\left\{x| x\in\mathbb{Z}, \ -5 \le x \le 0\right\}$ . The portion $x \in \mathbb{Z}$ means "x is in the set of integers". The Z refers to the German word Zahlen, which translates to "numbers".
C. This is false. The student used the correct inequality signs to indicate x is -5 or larger and also 0 or smaller; basically x is between -5 and 0 inclusive of both endpoints. The "or equal to" portions indicate we are keeping the endpoints and not excluding them.
D. This is false. Writing $-5 \ge x \ge 0$ would not make any sense. This is because that compound inequality breaks down into $-5 \ge x \ \text{ and } \ x \ge 0$ . Try to think of a number that is both smaller than -5 AND also larger than 0. It can't be done. No such number exists.
