Simplify the expression i⁸²

Answers

Answer:

We can use a trick here. Let's look at the first few exponents of i to realize this:

i^0 = 1

i^1 = i

i^2= -1

i^3 = -i

i^4 = 1

i^5 = i

i^6 = -1

i^7 = -i

we can see that the pattern (1, i, -1, -i) repeats. Since 82/2 = 41, and 41 is only divisible by 1, i^41 = i, and i^2 = -1. -1*i = -i, so i^82 = -i.

Complete the table of values for this absolute value function. Then use the drawing tool(s) to graph the function. F(x)-2|x+1|-1

Answers

Answer:

Please check the explanation!

Step-by-step explanation:

Given the equation

[tex]f\left(x\right)=-2|x+1|-1[/tex]

As some of the absolute rules are:

[tex]\left|a\right|=a,\:a\ge 0[/tex][tex]\:|-a|=a,\:\quad \:a>0[/tex]

NOW, let us solve!

Let us substitute all the table values

Putting x = -4

[tex]y=-2\left|-4+1\right|-1[/tex]        ∵[tex]\mathrm{Apply\:absolute\:rule}:\quad \left|a\right|=a,\:a\ge 0[/tex]

[tex]y=-6-1[/tex]

[tex]y=-7[/tex]

So, when x = -4, then y = -7

Putting x = -3

[tex]y=-2|-3+1|-1\:[/tex]

[tex]y=-4-1[/tex]

[tex]y=-5[/tex]

when x = -3, then y = -5

Putting x = -2

[tex]y=-2\left|-2+1\right|-1[/tex]

[tex]y=-2-1[/tex]

[tex]y=-3[/tex]

when x = -2, then y = -3

Putting x = -1

[tex]y=-2\left|-1+1\right|-1[/tex]

[tex]y=-0-1[/tex]

[tex]y=-1[/tex]

when x = -1, then y = -1

Putting x = 0

[tex]y=-2\left|0+1\right|-1[/tex]

[tex]y=-2-1[/tex]

[tex]y=-3[/tex]

when x = 0, then y = -3

Putting x = 1

[tex]y=-2\left|1+1\right|-1[/tex]

[tex]y=-4-1[/tex]

[tex]y=-5[/tex]

when x = 1, then y = -5

Miranda and Savannah are excited that a new store just opened in town! They go together the first day it opens! Each time Miranda goes to the store she plans to spend $7dollar sign, and each time Savannah goes to the store she plans to spend $9.A few weeks from now, Miranda and Savannah are surprised to find out that they have spent the exact same total amount of money at the store.

Answers

Answer:

Miranda made 9 visits to the store and Savannah made 7 visits to the store

Step-by-step explanation:

To find how many times Miranda and Savannah went to the store we would need to find the Greatest Common Multiple of the amount that each of them spends per visit. We do this by simply going through each of these numbers' times tables until we find a common one.

7 * 1 =  7                     9 * 1 = 9

7 * 2 =  14                   9 * 2 = 18

7 * 3 =  21                   9 * 3 = 27

7 * 4 =  28                  9 * 4 = 36

7 * 5 =  35                  9 * 5 = 45

7 * 6 =  42                  9 * 6 = 54

7 * 7 =  49                  9 * 7 = 63

7 * 8 =  56                  

7 * 9 =  63      

Finally, we can see that the first time that both Miranda and Savannah have spent the exact same amount would be when Miranda made 9 visits to the store and Savannah made 7 visits to the store. Each of which wasted $63

A skateboarder starting from rest accelerates down a ramp at 2 m/s for 2 s. What is the final speed of the skateboarder

Answers

Initial speed of the skateboard (u) = 0 m/s (Starts from rest)

Acceleration of the skateboard (a) = 2 m/s²

Time taken by the skateboard (t) = 2s

By using equation of motion, we get:

[tex] \bf \longrightarrow v = u + at \\ \\ \rm \longrightarrow v = 0 + 2 \times 2 \\ \\ \rm \longrightarrow v = 4 \: m {s}^{ - 1} [/tex]

[tex] \therefore [/tex] Final speed of the skateboard(v) = 4 m/s

The answer to 2+2 isnt 4 ill show you why

So you need to do f(x) 5x^2+3x-19+3

You would simplify the equation to get to y=4x+5f(x)+2

Naturally you would now graph the equation to a linear degree but still inducing a parabellum, y-(d-3)=0

Then solve using the square method (b/2)^2=(6)^2

Then put the 6 on both sides of the equation.

6^2+w0+8x+7t^2

Trina and Jessie went on a vacation to Hawaii. Trina went scuba diving and reached an elevation of −85.6 meters, which is below sea level.

Jessie went hang-gliding and reached an altitude of 87.9 meters, which is above sea level.

To Find :

The distance between them.

Solution :

Distance between them is :

[tex]D=87.9-(-85.6)\ m\\\\D = 173.5\ m[/tex]

Therefore, maximum distance between them is 173.5 m.

Hence, this is the required solution.

Many people think that a national lobby's successful fight against gun control legislation is reflecting the will of a minority of Americans. A previous random sample of 4000 citizens yielded 2250 who are in favor of gun control legislation. How many citizens would need to be sampled if a 90% confidence interval was desired to estimate the true proportion to within 4%?

Answers

Answer:

416

Step-by-step explanation:

Given that:

A previous random sample = 4000

Sample mean = 2250

[tex]\hat p = \dfrac{x}{n}[/tex]

[tex]\hat p = \dfrac{2250}{4000}[/tex]

[tex]\hat p = 0.5625[/tex]

The confidence interval level = 90%

Desired Margin of error E = 0.04

The level of significance at 90% C.I  = 1 - 0.90 = 0.10

The critical value [tex]Z_{\alpha/2} = Z_{0.10/2}[/tex]

[tex]\implies Z_{0.05} = 1.645[/tex]   ( From the  z tables)

[tex]n = \hat p \times (1- \hat p ) \bigg ( \dfrac{z_{0.05}}{E} \bigg)^2[/tex]

[tex]n = 0.5625 \times (1- 0.5625) \bigg ( \dfrac{1.645}{0.04} \bigg)^2[/tex]

[tex]n = 0.5625 \times (0.4375) \bigg ( 41.125 \bigg)^2[/tex]

n = 416.21

Thus, the number of citizens required to be sampled is [tex]\simeq[/tex] 416
