Which of these choices is equivalent to the expression: i85

Answers

Answer 1

Answer:

[tex]i^{85} = i[/tex]

Step-by-step explanation:

The options are missing; however, the question can still be solved.

Given

[tex]Number = i^{85}[/tex]

Required

Simplify

[tex]Number = i^{85}[/tex]

Rewrite 85 as 84 + 1

[tex]Number = i^{84 + 1}[/tex]

Split the expression using the law of indices

[tex]Number = i^{84} * i^1[/tex]

Rewrite 84 as 4(21)

[tex]Number = (i^{4})^{21} * i^1[/tex]

In complex numbers, [tex]i^4 = 1[/tex]

So, we have

[tex]Number = 1^{21} * i^1[/tex]

[tex]Number = 1 * i[/tex]

[tex]Number = i[/tex]

Hence;

[tex]i^{85} = i[/tex]

Step-by-step explanation:

The general equation of a straight line graph is y = mx + c, where m is the gradient of the line and c is the y-intercept.

Gradient = (2 - (-18)) / (3 - (-2)) = 20/5 = 4.

So y = 4x + c.

When x = 3, y = 2. (Given in the question)

This means that 2 = 4(3) + c, hence c = -10.

The answer is y = 4x - 10.

The path of water from a hose on a fire tugboat can be approximated by the equation y=-0.0055x^2 +1.15x + 5, where y is the height above the ocean and x is the distance from the tugboat. When the water is 6 ft above the ocean how far is it from the tugboat

Answers

Answer:

The water is 208.22ft from the tug boat

Step-by-step explanation:

The governing equation is [tex]y=-0.0055x^2 +1.15x + 5[/tex]

y is the height above the ocean

x is the distance from the tugboat

if y= 6ft, the equation will now become

[tex]6=-0.0055x^2 +1.15x + 5[/tex]

we can arrange this properly to form a quadratic equation by grouping like terms.

[tex]-0.0055x^2 +1.15x -1=0[/tex]

solving quadratically we have two values of x as  208.22ft and 0.873 ft.

We can take a more realistic value as a solution to our problems:

In this expression, we're dividing by a fraction, the fraction 4/5.  We can get the same result by inverting this divisor fraction, 4/5, and then multiplying 2/3 by 5/4:

Answer:

D. 0.64

Write 6 x 10 x 10 x 10 x 10 with an exponent. ​

Answers

Answer:

the answers is 6x 10 4

Step-by-step explanation:

The expression 6 x 10 x 10 x 10 x 10 with an exponent would be written as 6(10^4).

What are exponents?

The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.

If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

We have been given an expression as

6 x 10 x 10 x 10 x 10

Here we can see the base 10 multiplied by itself 4 times.

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^b \implies b= c \: \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]

The expression 6 x 10 x 10 x 10 x 10 with an exponent would be written as 6(10^4).

16/31 is the probability of picking black

13/31 is the probability of picking blue

Click on the graph until the graph of a line with undefined slope appears.

Answers

Answer:

The graph with the vertical line.

Step-by-step explanation:

All vertical lines have an undefined slope.  Horizontal lines have zero slope, and diagonal lines have a slope.

When calculating a slope for a vertical line, you would have to divide by zero. The quotient of any number and 0 are undefined, as you cannot divide by zero.  This is what makes vertical lines have an undefined slope.

Ava has 34 candy bars. If
a box contains 5 bars and she has 4 extra candy bars
determine how many boxes
She has?

Answers

[tex]\bf Step-by-step~explanation:[/tex]

If Ava has 34 candy bars, and each box can hold 5 bars, then we need to find out how many boxes that are filled up.

[tex]\bf Step~1:[/tex]

Divide the number of candy bars (34), by the number each box can hold (5)

[tex]\bf\frac{34}{5}=6.8[/tex]

Since we cannot have 6.8 boxes, we have to round down to 6.

[tex]\boxed{\bf Our~final~answer:~6~boxes}[/tex]

[tex]\bf Check~our~answer:[/tex]

To check our answer, we multiply the number of boxes (6), by the number of bars in each box (5), to get 30. We add Ava's extra bars (4), and we get the number we started off with: 34. This proves our answer is correct!

The cross-sectional areas of a right pyramid and a right cylinder are congruent. The pyramid has a height of five units, and a right triangle has a height of three units. Which conclusion could be made from the given information

Answers

Answer:

the volume of the right cylinder is 1.8 times the volume of the pyramid

Step-by-step explanation:

The volume of a pyramid is

[tex]V = \dfrac{1}{3} \times B\times H[/tex]

where the height of the pyramid is 5

[tex]V = \dfrac{1}{3} \times B\times 5[/tex]

[tex]V = \dfrac{5}{3} B \ units ^3[/tex]

On the other hand, the volume of a right cylinder is

V = BH

where the height of the right cylinder = 3 units

V = 3 B units³

Since we know that the cross-sectional areas are congruent, comparing the two-volume, we have the ratio of their volumes to be:

[tex]\dfrac{V_p}{V_c}= \dfrac{\dfrac{5}{3}B}{3B}[/tex]

[tex]\dfrac{V_p}{V_c}= \dfrac{5}{9}[/tex]

[tex]9 V_p = 5 V_c[/tex]

[tex]V_c = 1.8 \ V_p[/tex]

Hence, the volume of the right cylinder is 1.8 times the volume of the pyramid

Owen knows he only has three pencils in his backpack, and they are all yellow. He reaches into his backpack without looking and takes out a pencil. What is the probability that the pencil was yellow? Answer options with 5 options A. 0-thirds B. 1-third C. 2-thirds D. 3-thirds E. 3 over 1 I NEED ACTUAL ANSWERS NOT JUST STUPID PEOPLE WITH A POOR SENSE OF HUMOR

Answers

Answer:

D; 3-thirds

Step-by-step explanation:

Here is a probability question.

Firstly, we need to understand that the probability of any event is between 0 and 1; it cannot be negative and cannot be more than 1.

So the probability we want to calculate here is simply the probability of drawing a yellow pencil.

The way to go about this is by dividing the number of yellow pencils by the total number of pencils

Mathematically;

Probability of bringing out a yellow pencil= Number of yellow Pencils/ Total number of pencils

From the question, we are told that the number of pencils = number of yellow pencils = 3

Thus the probability will be 3/3 = 1

This cannot be found in the options right?

A)
-18
B)
-24
D
-28
D)
-36

Answers

Answer:

D

Step-by-step explanation:

Given

[tex]\frac{1}{4}[/tex] (2x + 8) = - 16

Multiply both sides by 4 to clear the fraction

2x + 8 = - 64 ( subtract 8 from both sides )

2x = - 72 ( divide both sides by 2 )

x = - 36

Answer:

The answer is option D

Step-by-step explanation:

[tex] \frac{1}{4} (2x + 8) = - 16[/tex]

First multiply through by 4

That's

[tex]4 \times \frac{1}{4}(2x + 8) = - 16 \times 4 \\ 2x + 8 = - 64[/tex]

Subtract 8 from both sides

We have

[tex]2x + 8 - 8 = - 64 - 8 \\ 2x = - 72[/tex]

Divide both sides by 2

That's

[tex] \frac{2x}{2} = - \frac{72}{2} [/tex]

We have the final answer as

x = - 36

Tina has 1/2 of a pan of cornbread left from a dinner party. She eats 1/2 of the leftover part the next night. How much of the whole pan does tina eat? Write and solve this equation

Answers

Answer:

Tina ate 3/4 of the whole pan of cornbread.

Step-by-step explanation:

Let the amount of cornbread in the initial pan be x.

After the dinner party, Tina has 1/2 of x left; That is 1/2x

If she eats 1/2 of the leftover, that will be 1/2 of 1/2x that is eaten. This will be 1/4x that is eaten.

To find the potion of the whole pan that Tina ate, we will add the potion she ate during the party to the portion of the leftover she ate the next night.

That will be 1/2x + 1/4x =3/4x

Therefore, Tina ate 3/4 of the whole pan of cornbread.
