Multiply, and Divide

2/ 2 - 15i

2(2 + 15i)/ (2 - 15i) * 2 + 15i

= ( 4 + 30i)/ (4 + 225)

=  (4 + 30i )/ 229


Hence; 2/ 2 - 15i 
 =  4/ 229 + 30i/ 229


Therefore, Letter Choice  (D); is your answer 4/229 + 30i/229






Hope that helps!!!!

My son, Garrett, is 11 years old and has a piggy bank that he wants to fill. He started with 5 one dollar bills. Every Saturday
Debora [2.8K]

Answer:

1) M(x) = 5 + 3x

2) Dependent variable; 3 dollar bills

Independent variable: chores

3) Range is continuous

Domain is discrete

4) Range: 0 ≤ x ≤ 10

Domain: 5 ≤ M ≤ 35

Step-by-step explanation:

We are told he started with 5 number of $1 dollar bills and that every Saturday, he earns 3 more $1 dollar bill.

Thus, total number of $1 bills earned after x number of Saturdays(weekly) is;

M(x) = 5 + 3x

After 10 weeks, total number is;

M(10) = 5 + 3(10)

M(10) = 35

The dependent variable is the 3 more dollar bills earned each Saturday because it depends on chores he completed. While the independent variable is the chores because it doesn't depend on anything.

After 10 weeks, the range and domain will be;

Range: 0 ≤ x ≤ 10

For the; Domain:

For x = 1, M(0) = 5 + 3(0) = 5

M(10) = 35

Thus;

Domain: 5 ≤ M ≤ 35

The range could be all numbers in the interval from 0 to 10. Thus, it is continuous.

Whereas, the domain doesn't contain all the numbers in the interval from 5 to 35. Thus it is Discrete.

Nikolay [14]

$12.80 is your answer.. see all you needed to do was divide $2.40 by three.. as that is one oz you would only then multiply by twelve for your answer.

A + b = dr, solve for a
AURORKA [14]

Hey there!

Since we don't have values for b, d, and r, we can't get a specific number for the value of a, if that makes sense. It'll be represented by these variables.

To solve, we need to make sure the equation looks like a = ? .

Subtract b from each side of the equation.

<u>a = dr - b </u>

Now we have solved for a.

Hope this helps!
