Which expression is equivalent i^233? On edge
Answer:
C
Step-by-step explanation:
Remember the four basic power of i:
[tex]\begin{aligned}i^1&=i\\i^2&=-1\\i^3&=-i\\i^4&=1\end{aligned}[/tex]
We have:
[tex]i^{233}[/tex]
The trick here is to split the exponent into a number divisible by 4 plus the remainder. Notice that:
[tex]233=232+1[/tex]
And that:
[tex]232/4=58[/tex]
So, we can rewrite our exponent as:
[tex]=i^{4\cdot 58+1[/tex]
Using the properties of exponents:
[tex]=(i^4)^{58}\cdot i^1[/tex]
Since i to the fourth is simply 1:
[tex]=(1)^{58}\cdot i^1[/tex]
Simplify:
[tex]=1\cdot i^1[/tex]
Simplify:
[tex]=i[/tex]
Hence, our answer is C.

1.red sky in the afternoon sunset
2. rainbows only appear after the rain
3. there's a pot of gold at the end of the rainbow
1.) As the sun light travels along path through as atmosphere to reach our eyes, the blue light has been mostly remove living mostly red and yellow light remain since red light waves are scattered the list by atmospheric gas molecules
2.) Rainbows are formed when it’s misty or spray the sky with water. It’s not solely just from after a rain; you only need water that can act at as prism and light to shine to create a rainbow.
3.) Having gold at the end of rainbow is just a myth since you can never reach the end of the rainbow. A rainbow is caused by dispersion of light in water droplet which is why they occur when sun comes out after rain.

Step-by-step explanation:
This is a difference of squares.
√x^2 - √49 is the basic formula for factoring a difference of squares. The idea is that the middle term has been cancelled out.
√x^2 = x
√49 = 7
(x - 7)(x + 7) is the way this factors.
(x - 7)(x + 7)
===========
(x + 7)
The (x +7) in the numerator cancels with the (x + 7) in the denominator.
The answer is (x - 7)
====================================================
She might have wanted you to do it like this.
(x + 7) || x^2 + 0x - 49 || x - 7
x^2 + 7x ........... Subtract
==========
-7x - 49
-7x - 49 ...... Subtract.
=============
0
Or she might have seen you do this
x^2 - 49 x^2 49
======= = === - =====
x + 7 x 7

Step-by-step explanation:
Answer:
b.) 350 = 0.25m + 300
Step-by-step explanation:
His earnings are a fixed amount, $300, and a variable amount that depends on the number of miles.
The variable amount depends on the number of miles he drives.
For 1 mile, he earns $0.25
For 2 miles, he earns $0.25 * 2
For m miles, he earns $0.25 * m
The total amount he earns is the fixed amount plus the variable amount
300 + 0.25m or 0.25m + 300
He earned $350, so we get the equation
350 = 0.25m + 300
Answer: b.) 350 = 0.25m + 300
in march, Arnold finds a guitar with a price of $650 that he wants to buy, but he only has $300 saved. In September, Arnold has 75% more money saved, and the guitar is on sale for a 30% discount off the original price. The sales tax is 5% of the sale price. Does Arnold have enough money to buy the guitar in September? justify your answer
Answer:
Yew, he has enough money to buy the guitar in september.
Step-by-step explanation:
300*0.75=225 300+225=525
650*0.35=195 650-195=455
sales tax: 455*0.05=22.75 455+22.75=477.75
Yes , Arnold have enough savings to buy the guitar
Savings amount of Arnold is $ 525 and the price of the guitar is $ 477.75
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the original price of the guitar be = $ 650
Let the initial savings of Arnold be = $ 300
Now , Arnold saved 75 % more than what he actually had
And , the equation will be
So , the new savings of Arnold is = 300 + ( 75/100 ) x 300
The new savings of Arnold is = 300 + ( 300 x 0.75 )
The new savings of Arnold is = 300 + 225
The new savings of Arnold is = $ 525
Now , the price of the guitar is discounted by = 30 %
And , the equation will be
So , the new price of the guitar after discount is = 650 - ( 30/100 ) x 650
The new price of the guitar after discount is = 650 - ( 650 x 0.30 )
The new price of the guitar after discount is = 650 - 195
The new price of the guitar after discount is = $ 455
Now , A sales tax of 5 % is priced on the guitar
And , the equation will be
So , the sale price of the guitar is = 455 + ( 5/100 ) x 455
The sale price of the guitar is = 455 + 22.75
The sale price of the guitar is = $ 477.75
Now , the new savings of Arnold is greater than the sale price of the guitar
$ 525 > $ 477.75
Therefore , Arnold have enough savings to buy the guitar
Hence , Yes , Arnold have enough savings to buy the guitar
Savings amount of Arnold is $ 525 and the price of the guitar is $ 477.75

The mean weight for team A with 15 members is 140 pounds, the mean weight for team B with 7 members is 135 pounds, and mean weight for team C with 20 members is 160 pounds. The overall mean weight for all three teams is
Answer:
86.74 pounds
Step-by-step explanation:
Team A
The mean weight for team A with 15 members is 140 pounds
Total weight for Team A = Mean × number is members
= 15 × 140 pounds
= 2100 pounds
Team B
The mean weight for team B with 7 members is 135 pounds
Total weight for Team B = Mean × number is members
= 7 × 135 pounds
= 945 pounds
Team C
Mean weight for team C with 20 members is 160 pounds.
Total weight for Team C = Mean × number is members
= 20 × 160 pounds
= 3200 pounds
The total number of members from the 3 teams =( 15 + 7 + 20) members
= 42 members
The total weight in pounds from the 3 teams = (2100 + 945 + 3200)
= 6245 pounds
The overall mean weight for all three teams is calculated as:
6245/42 members
= 86.736111111 pounds
Approximately = 86.74 pounds

A worker is spray painting doors. It takes LaTeX: \frac{2}{5} 2 5 of a can of spray paint to paint 1 door. The worker has 2 cans of spray paint total. How many doors can the worker paint? Group of answer choices
Answer:
5 doors
Step-by-step explanation:
Can of spray paint : door painted = 2/5 : 1
The worker has 2 cans of spray paint total.
How many doors can the worker paint?
Let x = number of doors the worker can paint
Can of spray paint : door painted
2 : x
Equate both ratios
2/5 : 1 = 2 : x
2/5 ÷ 1 = 2/x
2/5 × 1/1 = 2/x
2/5 = 2/x
Cross product
2 * x = 5 * 2
2x = 10
x = 10/2
x = 5 doors
The worker can paint 5 doors with 2 cans of spray paint

You are participating in a "Secret Gift Exchange" with your friends. You set
two price requirements: You can spend less than $30, but you must also
spend more than 20. Write the compound inequality. *
Answer:
FOREVER AND ALWAYS
Step-by-step explanation:
i love you more than you know:( <3
see you someday
The compound inequality which represents the given situation is 20 < x < 30.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
Let's say x represents the spend.
As per the given,
You can spend less than $30,
x < 30
You must also spend more than 20.
x > 20
Compound,
30 < x < 20
Hence "The compound inequality which represents the given situation is 20 < x < 30".
