Answer: B) -1/3i
Step-by-step explanation: 81(-1/3i)^4
Answer:
Step-by-step explanation:
81x^4=1
x^4=1/81
(x^4)^(1/4)=(1/81)^(1/4)
x=+\-1/3
so -1/3 is a solution

From a train station, one train heads north, and another heads east. Some time later, the northbound train has traveled 27 kilometers, and the eastbound train has traveled 36 kilometers. How far apart are the two trains, measured in a straight line?
Answers
Answer: the eastbound train had travelled 12 miles
Explanation: using Pythagoras theorem, we know that
X^2 = a^2 + b^2
Where ^ stands for raised to power.
Let
a stand for the train going towards North and
b stands for the train going towards east.
X stands for the total distance between train a and b = 20 miles.
By Pythagoras rule
X^2 = a^2 + b^2
20^2 = 16^2 + b^2
400 = 256 + b^2 so that
b^2 = 400 - 256 = 144
b = √144
b = 12 miles.

roots are 11/2,4
The required value of the b is -3/2, and another root of the given equation is -11/2.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given expression,
x² - bx - 22 = 0
As we know 4 is the root of the equation,
put 4 in the given expression,
(4)² -b(4) -22 = 0
16 -4b -22 = 0
b = -3/2
x² + 3/2x - 22 = 0
(x - 4)(x + 3/2) = 0
root are,
x = 4 and -11/2
Thus, the required value of the b is -3/2, and another root of the given equation is -11/2.

The slope of the linear function represented by the table is -6.
To find the slope of the linear function represented by the table, we can use the formula for slope:
Slope (m) = (change in y) / (change in x)
Let's calculate the slope using two points from the table. We'll choose the points (-1, 2) and (2, -16):
(change in y) = -16 - 2 = -18
(change in x) = 2 - (-1) = 3
Slope (m) = (-18) / (3) = -6
Therefore, the slope of the linear function represented by the table is -6.

Determine if the sequence below is arithmetic or geometric and determine the
common difference / ratio in simplest form.
4, 20, 100
Answers
Answer:
Step-by-step explanation:
a₂ - a₁ = 20 - 4 = 16
a₃ - a₂ = 100 - 16 = 84
Since a₂ - a₁ ≠ a₃ - a₂, the sequence is not arithmetic.
a₂/a₁ = 20/4 = 5
a₃/a₂ = 100/20 = 5
Since a₂/a₁ = a₃/a₂ = 5, the sequence is geometric with a common ratio of 5.
Find the total amount due on a simple-interest loan if the principal is $5,000 with a rate of 4% for 12 years
Answers
Answer:
$7400
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
I = 5000 × 0.04 × 12 = 2400
I = $ 2,400.00
The simple interest accumulated
on a principal of $ 5,000.00
at a rate of 4% per year
for 12 years is $ 2,400.00.
The total amount due on a simple-interest loan if the principal is $5,000 with a rate of 4% for 12 years is $2400 and this can be determined by using the simple interest formula.
Given :
The total amount due on a simple-interest loan if the principal is $5,000 with a rate of 4% for 12 years.
The total amount due on a simple interest loan can be determined by using the simple interest formula which is given by the equation:
[tex]\rm I = PRT[/tex]
Given that time, T = 12 years
Rate, R = 4% = 0.04
Principal amount, P = $5000
Now, put the value of P, R, and T in the equation (1).
[tex]\rm I = 5000\times 0.04 \times 12[/tex]
I = $2400
The total amount due on a simple-interest loan if the principal is $5,000 with a rate of 4% for 12 years is $2400.

OC.
It is the graph of y = x translated 13 units up.
OD. It is the graph of y = x where the slope is decreased by 13.

Step-by-step explanation:
Translation of a Graph
If the graph of
y=f(x) is translated a units horizontally, then the equation of the translated graph is
y =f(x - a)
The value of a is considered positive for translations to the right.
The parent function is
y = x
and the given function is
y = x - 13
The translation corresponds to a translation of 13 units to the right
