Consider Z1= 4-4 radical 3i and Z2= -16 i. What is Z1-Z2?

Answers

Answer 1

Answer:

Option (3)

Step-by-step explanation:

[tex]Z_1=4-4\sqrt{3}i[/tex]

[tex]Z_2=-16i[/tex]

[tex]Z_1-Z_2=(4-4\sqrt{3}i)-(-16i)[/tex]

[tex]=4-4\sqrt{3}i+16i[/tex]

[tex]=4-(4\sqrt{3}i-16i)[/tex]

[tex]=4-4(\sqrt{3}-4)i[/tex]

Therefore, Option (3) will be the correct option.

the correct answer is marked

Step-by-step explanation:

When the graph of the left side of the equation does not intersect the graph of the right side of the equation, there are no solutions.

Additional comment

Even if you extend the domain to complex numbers, there are no solutions. The f(x) = |x| function always returns a positive real value, even for complex numbers.

Bella wants to create a tea-mix. She can buy Asian Treasure tea for $7.50 per ounce and Paradise tea for $5.00 per ounce. If she wants to make 60 ounces of tea-mix at a cost of $6.00 per ounce, how many ounces of Asian Treasure tea and how many ounces of Paradise tea should she buy?

Answers

9514 1404 393

Answer:

24 oz Asian Treasure36 oz Paradise

Step-by-step explanation:

The proportion of Asian Treasure is the difference in price of the mix and Paradise tea, divided by the difference in price of Asian Treasure and Paradise tea. So the amount of Asian Treasure is ...

(6.00 -5.00)/(7.50 -5.00)(60 ounces) = 24 ounces . . . Asian Treasure tea

The remaining 60-24 = 36 ounces will be Paradise tea.

Using an equation

You can get the same result if you define a variable (a) to the amount in ounces of the higher-priced contributor. Then the lower-priced contributor will be in the amount (60-a) ounces. The total cost of the mix is ...

7.50a +5.00(60 -a) = 60(6.00)

(7.50 -5.00)a +60(5.00) = 60(6.00) . . . rearrange the left side

(7.50 -5.00)a = 60(6.00 - 5.00) . . . . . . subtract 60(5.00)

a = 60(6.00 -5.00)/(7.50 -5.00) . . . . . . divide by the coefficient of 'a'

Note that this last expression is identical to the one we used above to find the quantity of Asian Treasure tea.

what is There are fourteen whole snack bars on a plate. There are five friends.
Carl eats 2.5 snack bars.
Dave eats 2.7 snack bars.
Tony eats 2.5 snack bars.
Gary eats 2.0 snack bars.
Tyrone eats 2.3 snack bars.
Carl says he ate the most snack bars. Is Carl correct? There are no more snack bars on the plate. Gary looks at the snack bar pieces that each friend has left. Gary says they only ate a total of a dozen snack bars. How does Gary know that the friends only ate a total of a dozen snack bars? Show all your mathematical thinking.

Answers

Carl is incorrect. Dave ate a higher fraction of snack bars, by 0.2 snack bars.

Carl had .5 left of a snack bar.

Dave had .3 left of a snack bar.

Tony had .5 left of a snack bar.

Gary had .0 left of a snack bar.

Answer: [tex]x < 3[/tex]

Explanation:

To isolate x, we first add 3 to both sides. Then we'll divide both sides by 4

[tex]4x-3 < 9\\\\4x-3+3 < 9+3\\\\4x < 12\\\\\frac{4x}{4} < \frac{12}{4}\\\\x < 3[/tex]

So x can be any number smaller than 3.

The inequality sign will not flip because we are not dividing both sides by a negative number.

Answers

Answer:

Multiplying and dividing fractions are essentially the same process which you multiply the numbers straight across and no need for common denominators. Except in division of fractions, the second fraction is flipped so that the denominator is on the top and the numerator is on the bottom (reciprocal).

Step-by-step explanation:

Example:

[tex]\frac{3}{4} * \frac{1}{5} = \frac{3}{20}[/tex]

[tex]\frac{3}{4}[/tex] ÷ [tex]\frac{1}{5} = \frac{3}{4} * \frac{5}{1} = \frac{15}{4}[/tex]
