Answer:
[tex]8i^{22}[/tex] - 1
Explanation:
It's actually quite easy to tell which simplifies to a real number without working out the problem.
[tex]i^{2}[/tex] = -1
Any imaginary number with an even exponent is simplified to a real number. If it has an odd exponent, it cannot be simplified to a real number.
Some tips for fully solving the expression:
If the exponent is divisible by 4, then don't change the sign of the coefficient. You're just multiplying it by 1 because [tex]i^{4}[/tex] = [tex](i^{2})^{2}[/tex] = [tex](-1)^{2}[/tex] = 1
If the exponent is divisible by 2, change the sign of the coefficient because you're multiplying it by -1.

Answer:
22 ft.
Step-by-step explanation:
First we can get the total change in elevation, which should be the final elevation minus the initial elevation:
(98ft)-(10ft)=88ft
Then, to get the change in 4 equal intervals, we can divide the total change in elevation by 4.
(88/4)ft=22ft
So during each of the four intervals, assuming they were four equal intervals, the diver descends 22ft.

Harvey is 3 times as old as Jane. The sum of their ages is 52 years. Find the age of each. Jane is 13 and Harvey is 39 Jane is 12 and Harvey is 48 Jane is 13 and Harvey is 48
Answer:
13, 39
Step-by-step explanation:
H +J =52
H=3J
3J +J=52

Solve the equation. Show your work / explain your steps. x - 5 + 3x = -21
Answer:
X = -4
Step-by-step explanation:
See image for explanation
Answer:
x=4
Step-by-step explanation:
x - 5 + 3x = -21
add 3x and x and add 5 to both sides of the equation
4x = -16
then divide both sides by 4
x = 4
ya answer is x = 4

DaniElSabiondoWhat is the mean of 25, 27, 32, 29, 42?
Step-by-step explanation:
To find the mean, or average, you add all of the numbers and divide the sum by how many there are.
In this case, you add 25,27,32,29, and 42 and then divide the sum by 5.
25+27=52+32=84+29=113+42=155.
Then divide.
155/5=31.

Which is a y-intercept of the continuous function in the table? (0, –6) (–2, 0) (–6, 0) (0, –2)
Answer:
(0, - 6)
Step-by-step explanation:
The y- intercept is where the function crosses the y- axis.
This occurs when x = 0 , thus
From the table when x = 0, f(x) = - 6
The y- intercept is therefore (0, - 6 )
Answer:
(0, - 6)

Step-by-step explanation:
if y varies directly with x, and y = -20 and x = 5, what is x when y = -30
Answer:
7.5
Step-by-step explanation:
The value of x = 7.5 when y = -30
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Given that y varies directly with x, and y = -20 and x = 5,
To determine the value of x = 7.5 when y = -30
Direct variation equations can be written as:
y = kx where "k" is a constant.
Substitute the values of y = -20 and x = 5 in the direct variation equation and solve for k:
⇒ -20 = 5k
⇒ k = -20/5
⇒ k = -4
The direct variation equation :
⇒ y = -4x
Substitute the values of y = -30 in the above equation and solve for x:
⇒ -30 = -4x
⇒ 4x = 30
⇒ x = 30/4
⇒ x = 7.5
Thus, the value ofx = 7.5 when y = -30

JK = 7x + 9
JL = 114, and
KL = 9x + 9,
Find KL.
Answer:
KL= 63
Step-by-step explanation:
JK=7x+9 , JL=114 , KL=9x+9 ( if the points are on the same line and point J at the end point and K in the middle)
*J_______________________K___________________________L
JL=JK+KL
114=7x+9+9x+9
114-18=16 x
16x=98
x=98/16=6
KL= 9x+9
KL=9(6)+9
KL= 63

The sum of 20.7 and a number is 50.5.
Answer:
x = 29.8
Step-by-step explanation:
x represents the unknown number
20.7 + x = 50.5
x + 20.7 - 20.7 = 50.5 - 20.7
x = 50.5 - 20.7
x = 29.8
