Answer:

8.30

Step-by-step explanation:

Lee mailed 3 packages

If he paid 1.70 for 1 package and 3.60 for 2 package

= 3.60×2 + 1.70

= 7.2+1.70

= 8.9

If Lee paid 3.60 for 1 package and 1.70 for 2 packages

= 3.60 + 1.70(2)

= 3.60 + 3.4

= 7

Hence the price paid to mail the thee packages is 8.30 because it falls in between 7 and 8.9

Answer: a. $8.30

Step-by-step explanation:

Highest paid was $3.60 and lowest paid was $1.70. There is a middle package that cost less than $3.60 and more than $1.70.

= 3.6 + 1.7

= $5.30

This rules out option c because we have not added the price of the third package and it is already higher than option c.

Add the maximum twice:

= 3.6 + 3.6 + 1.7

= $8.90

If the second package was assumed to have the same cost as the highest paid, the total would still be less than options b and d which makes them both wrong.

<em>Option a is the most feasible answer. </em>

Explain and demonstrate the multiplication of complex conjugates using 2+3i and its complex conjugate. Be sure to discuss all st
krok68 [10]

The product of a <em>complex</em> number and its conjugate is (a + i b) · (a - i b), where a and b are <em>real</em> numbers, and the result for the <em>complex</em> number 2 + i 3 is 13.

<h3>What is the multiplication of a complex number and its conjugate</h3>

Let be a <em>complex</em> number a + i b, whose conjugate is a - i b. Where a and b are <em>real</em> numbers. The product of these two numbers is:

(a + i b) · (a - i b)

Then, we proceed to obtain the result by some algebraic handling:

a · (a + i b) + (- i b) · (a + i b)

a² + i a · b - i a · b - i² b²

a² - i² b²

a² + b²

If we know that a = 2 and b = 3, then the product of the complex number and its conjugate is:

z\cdot \bar z = 2^{2} + 3^{2}

z\cdot \bar z = 13

Find the values of x and y. State which theorem(s) you used.
Usimov [2.4K]

The required simplified value of x and y is 32 and 84 respectively.

Given that,
To find the values of x and y. State which theorem(s) you used.

<h3>What is simplification?</h3>

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Vertical opposite angles

3x = 5x - 64
2x = 64
x = 32

Now,

5x - 64 = 5*32 - 64
            = 160 - 64

            = 96°
Now complementary angle y
y = 180 - 96°

y = 84°


Thus, the required simplified value of x and y is 32 and 84 respectively.
