Answer:

d 1–2i

Step-by-step explanation:

(4–7i)+(–3+5i)=1–2i

The sum of the complex numbers 4−7i and −3+5i is obtained by adding the real parts and the imaginary parts separately. This gives a result of 1 - 2i.

To find the sum of two complex numbers, you simply add the real parts together and the imaginary parts together separately.

So, you add the real parts (4 and -3), which equals 1, and the imaginary parts (-7i and 5i), which equals -2i.

Thus, the sum of the complex numbers 4−7i and −3+5i is 1 - 2i.

Answer:

0.9333 as a fraction equals 9333/10000

Step-by-step explanation:

0.9333 = 0.9333/1 = 9.333/10 = 93.33/100 = 933.3/1000 = 9333/10000

Answer:

f(2)=0

f(-4)=24

Step-by-step explanation:

We are given

f(n)=n^2-2n

We are asked which of the following are true?

f(2)=0

f(1)=3

f(-4)=24

f(5)=35

f(-2)=0

Let's start with f(2)=0.

f(2)=2^2-2(2)

f(2)=4-4

f(2)=0

So f(2)=0 is true.

Moving on to f(1)=3.

f(1)=1^2-2(1)

f(1)=1-2

f(1)=-1

So f(1)=3 is false.

Now for f(-4)=24.

f(-4)=(-4)^2-2(-4)

f(-4)=16+8

f(-4)=24

So f(-4)=24 is true.

f(5)=35?

f(5)=5^2-2(5)

f(5)=25-10

f(5)=15

So f(5)=35 is false.

Finally f(-2)=0.

f(-2)=(-2)^2-2(-2)

f(-2)=4+4

f(-2)=8

So f(-2)=0 is false.

Answer:

The correct option are,

f(2) = 0, and f(-4) = 24

Step-by-step explanation:

Given function,

[tex]f(n) = n^2 - 2n[/tex]

By substituting n = 2,

[tex]f(2) = 2^2 - 2(2) = 4 - 4 = 0[/tex]

By substituting n = 1,

[tex]f(1) = 1^2 - 2(1) = 1 - 2 = -1[/tex]

By substituting n = -4,

[tex]f(-4) = (-4)^2 - 2(-4) = 16 + 8 = 24[/tex]

By substituting n = 5,

[tex]f(5) = (5)^2 - 2(5) = 25 - 10 = 15[/tex]

By substituting n = -2,

[tex]f(-2) = (-2)^2 - 2(-2) = 4 + 4= 8[/tex]

Answer:

19,549

Step-by-step explanation:

If 26,000 ( I'll assume you missed a 0) is 33% more than their total the previous year.

If the previous year is supposed to be 100%, this year is 100% + 33% = 133%

Using rule of three:

26,000 -> 133%

x -> 100%

x = 100/133 * 26,000 = 19,549

Answer:

The answer would be 3.

Step-by-step explanation:

This can be found by subtracting 12 from both sides and then the x will be alone on one side and be set equal to 3 on the other side.

The total number of blocks in Troy's toy bin is 50, which is the sum of 14 red blocks, 20 yellow blocks, and 16 blue blocks.

To solve the problem regarding Troy's toy bin, we need to use basic arithmetic to calculate the total number of blocks of each color and then add them together to find the total number of blocks in the bin.

Troy has 14 red blocks, so let's represent the number of red blocks as R = 14. It's mentioned that there are 6 more yellow blocks than red blocks, which means the number of yellow blocks Y = R + 6 = 14 + 6 = 20.

The problem states that there are 2 more blue blocks than red blocks, so the number of blue blocks B = R + 2 = 14 + 2 = 16.

Now, to find the total number of blocks in the bin, we simply add the numbers of red, yellow, and blue blocks:

Total blocks = R + Y + B = 14 + 20 + 16 = 50.

Therefore, there are 50 blocks in Troy's toy bin in all.

Step-by-step explanation:

answer would be a because a reflection does not change the size or shape of any figure

A reflection of a shape maintains its size and shape, changing only its position and orientation. Thus, the perimeters and corresponding side lengths of reflected triangles FGH and ABC are equal.

When a shape is reflected across a line, its shape and size remain the same, although its orientation and position may change. Therefore, a reflection is a type of transformation called an isometry, also known as a congruence transformation. In the case of triangle FGH being reflected to form triangle ABC:

Answer:

(2x6)+6

2x6=12

12+6=18

Final answer:

Two-step equations that equal 18 can be solved by performing two operations to isolate the variable, such as subtracting and then dividing, or adding and then dividing.

Explanation:

A student is asking for examples of two-step equations that result in an answer of 18. Two-step equations involve performing two operations to solve for the unknown variable. For instance, a simple two-step equation could be x/2 + 5 = 14, where you would first subtract 5 from both sides to get x/2 = 9, and then multiply both sides by 2 to find x = 18.

Another example could be 2x - 4 = 32. To solve this equation, you would first add 4 to both sides, resulting in 2x = 36, and then divide both sides by 2 to get x = 18.

These examples help students understand how to manipulate equations using addition, subtraction, multiplication, or division to isolate the variable and solve the equation.

Tom's best strategy would be to keep a minimum balance of $1,000 in his CD to meet his bank minimum requirement.

From the given information, Tom's income can change from month to month and he needs to withdraw money from his CD to pay monthly bills, he should plan ahead and withdraw the necessary amount in one go to minimize the number of early withdrawals.

Withdrawing $250.00 from his CD every month for bills would result in multiple early withdrawals, incurring multiple penalties.

Thus, Tom's best strategy would be to keep a minimum balance of $1,000 in a separate CD for longer-term savings and avoid multiple early withdrawals.

Also he should keep the majority of his funds in a regular savings account or money market account for more flexibility in managing his irregular income and monthly expenses.

Answer:

x = [tex]\frac{g-f}{h-e}[/tex]

Step-by-step explanation:

Given

f - ex = g - hx

Collect the terms in x on the left side by adding hx to both sides

hx - ex + f = g ( subtract f from both sides )

hx - ex = g - f ← factor out x on the left side

x(h - e) = g - f ← divide both sides by (h - e)

x = [tex]\frac{g-f}{h-e}[/tex]

x = 6; ∠ONP = 24°

Step-by-step explanation:

1. Find the value of x

[tex]\begin{array}{rcl}\angle MNP & = & \angle MNO + \angle ONP\\3x^{2} + 12 & = & x^{2} + 10x + x^{2} - 2x\\3x^{2} + 12 & = & 2x^{2} + 8x\\x^{2} + 12 & = & 8x\\x^{2} -8x + 12 & = & 0\\(x - 2)(x - 6) & = & 0\\\end{array}[/tex]

[tex]x = 2 \text{ or }x = 6[/tex]

2. Find the measures of the angles

(a) x = 2

∠ ONP = x² - 2x = 2² - 2(2) = 4 - 4 = 0

This answer does not make sense because O lies in the interior of ∠MNP.

We disregard x = 2.

(b) x = 6

∠ ONP = x² - 2x = 6² - 2(6) = 36 - 12 = 24

Answer:

It is needed [tex]\frac{8}{5}[/tex] cups of yellow paint to mix with one cup

of red paint

Step-by-step explanation:

* Lets explain how to solve the problem

- To make the orange pint, Roger mixed 5/8 cup of red paint to one

 cup of yellow paint

∴ The ratio of red paint to yellow paint is 5/8 : 1

- Lets simplify it by multiplying the two terms of the ratio by 8

∵ [tex]\frac{5}{8}(8):1(8)[/tex]

∴ The ratio of red paint : yellow paint = 5 : 8

∴ For every 5 cups of red paint we need 8 cups of yellow paint to

  make the orange paint

- We need to know how many yellow paint is needed to mix with

 one cup of red paint

∵     red paint        :        yellow paint

            5               :                 8

             1               :                 ?

- By using cross multiplication we can find the number of yellow cups

∴ The number of the yellow cups = [tex]\frac{1*8}{5}=\frac{8}{5}[/tex]

∴ It is needed [tex]\frac{8}{5}[/tex] cups of yellow paint to mix with one
