Answers

Answer 1

Answer:

13

Step-by-step explanation:

(3-2i)(3+2i)

as (a+b)(a-b) =a²-b²

3²-(2i)²

=9-(4*-1)

=9-(-4)

=9+4

=13

Hope this helps you!

Answer 2

Answer:

13

Step-by-step explanation:

3^2=9, 2i*(-2i)=-4i^2=4

Answers

Answer: Choice B

The equation is sometimes true. When x = 0, 1 or -1, then the equation is true. Otherwise, the equation is false.

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

Explanation:

When it comes to something like "always true" all we need is one counter example to break that statement. Pick something like x = 64 and you'll find that the left hand side becomes

[tex]x^{1/3} = 64^{1/3} = \sqrt[3]{64} = \sqrt[3]{4^3} = 4[/tex]

while the right hand side turns into

[tex]x^3 = 4^3 = 4*4*4 = 64[/tex]

This means the original equation [tex]x^{1/3} = x^3[/tex] updates to [tex]4 = 64[/tex] after plugging in x = 4. We get a false statement making the original statement false when x = 4. So saying  "[tex]x^{1/3} = x^3[/tex] is always true" is not correct.

----------------------

The equation is only sometimes true for the x values 0, 1 and -1

Let's try x = 0

[tex]x^{1/3} = x^3\\\\0^{1/3} = 0^3\\\\0 = 0[/tex]

we get a true statement confirming x = 0 as a solution

Trying x = 1 leads to

[tex]x^{1/3} = x^3\\\\(1)^{1/3} = 1^3\\\\1 = 1[/tex]

also true. A similar situation happens with x = -1 as well, just that we have negatives this time.

Which expression is equivalent to the given expression? 2x - 11x-6 A. 2(x – 3) (x + 1) B. (2x + 3)(x- 2) C. (2x+ 1)(x- 6) D. 2(x + 3)(x- 2)​

Answers

Answer:

Option C. (2x + 1)(x - 6)

Step-by-step explanation:

To know which option is equivalent to 2x² - 11x - 6, we shall simplify the expression as follow:

2x² - 11x - 6

Multiply the 1st term (i.e 2x²) and last term (i.e - 6) together. This is illustrated below:

2x² × - 6 = - 12x²

Next, find two factors of - 12x² such that when we add them together, it will result to the 2nd term (i.e - 11x) in the expression above.

The factors are x and - 12x

Next, replace - 11x with x and - 12x in the expression 2x² - 11x - 6 as shown below:

2x² - 11x - 6

2x² + x - 12x - 6

Next, we shall factorise the expression 2x² + x - 12x - 6 as follow:

2x² + x - 12x - 6

x(2x + 1) - 6(2x + 1)

(2x + 1)(x - 6)

Thus,

2x² - 11x - 6 is equivalent to (2x + 1)(x - 6)

A square garden has an area of 100 square feet. What is the perimeter of the garden? show your work.​

Answers

Answer: 40

Step-by-step explanation: 10 • 10 equals 100, so each side is 10. Since a square has 4 sides multiply 4 by 10 which gets you 40.

Perimeter of a square garden is 40.

Here,

A square garden has an area of 100 square feet.

We have to find the perimeter of the square garden.

What is Perimeter of square?

Sum of all four sides of a square is known as Perimeter of a square.

Now,

Let side of a square garden is a.

Area of a square = [tex]side^{2}[/tex] = [tex]a^{2}[/tex]

[tex]a^{2} = 100[/tex]

[tex]a = 10[/tex]

Hence, Perimeter of a square garden = 10 + 10 + 10 + 10

                                                          = 40

So, Perimeter of a square garden is 40.

Which number is the smallest? 4.4 ⋅ 10−5, 3.99 ⋅ 10−6, 2.6 ⋅ 102, 1.85 ⋅ 103

Answers

Answer:

3.99 10-6

Step-by-step explanation:

This is simply the answer because if you multiply them all out this equation is the smallest number

Answer:

3.99*10^-6

Step-by-step explanation:

Anything taken to a negative power is going to be smaller than the original number because x^-y=1/(x^y). So since 3.99*10^-6 is smaller than 4.4*10^-5, the former is the answer.

Which number is less than 2.16? 2.3, 2.09, 2.93, or 2.9

Answers

Answer:

2.09

Step-by-step explanation:

Because:

2.3=2.30

2.9=2.90

and 2.93 is just bigger

therefore your answer is 2.09

Answer:

2.09

Step-by-step explanation:

2.93 > 2.9 > 2.3 > 2.16 > 2.09

2.09 is less than 2.16 mainly due to the fact that 9 is in the hundredths place. 16 is also in the hundredths place, but 9/100 is less than 16/100.

Answers

Answer:

[tex]Distance = 1572\ feet[/tex]

Step-by-step explanation:

Given

Courthouse = 1068 feet

Gallery = 0.5 mile ----- Missing Part of Question

What the question implies is to

determine the distance between these two locations

This is done as follows:

[tex]Distance = |Courthouse - Gallery|[/tex]

Substitute values for Courthouse and Gallery

[tex]Distance = |1068\ feet - 0.5\ mile|[/tex]

Convert 0.5 mile to feet (1 mile = 5280 feet)

[tex]Distance = |1068\ feet - 0.5 * 5280\ feet|[/tex]

[tex]Distance = |1068\ feet - 2640\ feet|[/tex]

Let the universal set be the set of integers and let A​ = {x​ | ​≤ 5}. Write A using the roster method.

Answers

Answer: A = {..., -1, 0, 1, 2, 3, 4, 5}

Step-by-step explanation:

We have that the set A is the set of all the integers equal to or smaller than 5.

To write in the Roster Method, we must list all the elements of this set, but we know that this set extends to minus infinity, then we should start with an ellipsis:

A = {...

Which means that it continues in that direction.

Then we can implicitly write the end of our set, and also some of the points so we can know the relation between the points in the set.

A = {..., -1, 0, 1, 2, 3, 4, 5}

And that is the set A in written with the Roster Method

A sample of 2,000 people yielded P(hat) = .52. What is the variance of the population proportion?
a. .0056
b. .0161
c. .0112
d. .00012

Answers

Answer:

d. .00012 or 0.00012

Step-by-step explanation:

The variance of the population proportion formula is given as:

p(1 - p)/n

Where n = sample size

p = population proportion or p(hat)

n = 2000 people

p = 0.52

Variance of the population proportion = 0.52(1 - 0.52)/ 2000

= 0.52 × 0.48 /2000

= 0.2496 /2000

= 0.0001248

Therefore the Variance of the population proportion is approximately = 0.00012

Describe how you would graph a figure that is translated by (x - 4, y + 2).

Answers

Answer:

see explanation

Step-by-step explanation:

Given the translation rule

(x, y ) → (x - 4, y + 2 )

This means subtract 4 from the original x- coordinate and add 2 to the original y- coordinate, that is

a point (4 , - 4 ) → (4 - 4, - 4 + 2 ) → (0, - 2 )

The resulting graph would result in moving input x by --4  horizontally and Output y by +2 vertically.

What is a translation of a point?

Translations are defined by saying how much a point is moved to the left/right and up/down. Vertically translating a graph is equivalent to shifting the base graph up or down in the direction of the y-axis. A graph is translated k units vertically by moving each point on the graph k units vertically.

Given the point  (x - 4, y + 2), we can clearly observe that the graph would move vertically by +2 units while the input will be in the -ve x-axis direction from right to left and thus will move negatively by -4.

Hence, The resulting graph would result in moving input x by --4  horizontally and Output y by +2 vertically.
