Step-by-step explanation:
note that i² = - 1
Thus
[tex]i^{8}[/tex]
= i² × i² × i² × i²
= - 1 × - 1 × - 1 × - 1
= 1 × 1
= 1
The value of complex number is 1. Therefore, the option B is the correct answer.
What is the complex number?A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z.
The given complex number is i⁸.
We know that, i²=-1
Now, i⁸ can be written as i²×i²×i²×i²
= -1×(-1)×(-1)×(-1)
= 1
Therefore, the option B is the correct answer.

Which choice is equivalent to the quotient shown here for acceptable values of x?
Answer:
(D)
Step-by-step explanation:
Equivalent expressions are expressions that have equal values
The equivalent expression of [tex]\sqrt{8x^2 } \div \sqrt{3x}[/tex] is [tex]\sqrt{\frac{8x}{3}}[/tex]
The expression is given as:
[tex]\sqrt{8x^2 } \div \sqrt{3x}[/tex]
Represent the expression as a quotient
[tex]\sqrt{8x^2 } \div \sqrt{3x} = \sqrt{\frac{8x^2}{3x}}[/tex]
Evaluate the quotient
[tex]\sqrt{8x^2 } \div \sqrt{3x} = \sqrt{\frac{8x}{3}}[/tex]
Hence, the equivalent expression of [tex]\sqrt{8x^2 } \div \sqrt{3x}[/tex] is [tex]\sqrt{\frac{8x}{3}}[/tex]

what is 10 1/3 x 1/4? that is, what is ten and one third times one fourth?
Answer: 31/12, or 2 7/12
Step-by-step explanation: The answer is actually very simple. All you have to do is to simplify 10 1/3 into 31/3, as 10x3+1=31. Then, you have to multiply 31/3 with 1/4. Do a simple fraction multiplication, and you get 31/12, or 2 7/12 if your teacher is asking for a mixed number. Sometimes simplifying is better
Sarkis wants to draw a triangle with sides measuring 4 ft, 10 ft, and 16 ft. Which is true about Sarkis’s plan?
Answer: Sarkis cannot draw a triangle with these side lengths.
Step-by-step explanation: The triangle inequality theorem states that the sum of any two sides of a triangle must be greater than the other side.
The two smallest sides are 4 and 10; their sum is 14. This is shorter than the longest side, so these will not make a triangle.

A proportional relationship is shown in the table below: x 0 3 6 9 12 y 0 0.5 1.0 1.5 2.0 What is the slope of the line that represents this relationship? \qquad Graph the line that represents this relationship.
Answer:
Take two point from the table, doesn't matter which ones, because this is linear. I will choose (0,0) and (3,.5).
Now follow the equation for slope: m = change in y / change in x.
[tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{.5-0}{3-0}[/tex]
[tex]\frac{.5}{3}[/tex]

The slope is 1/6. m=1/6
Its y-intercept is at 0. b=0
So the equation is y = 1/6x. The graph is attached.

I bought a box from the post office that has a volume of 24 cubic centimeters,
Which of the following could be the dimensions of my box?
A. 8cm long, 1cm wide, 3cm high
B.10cm long, 4cm wide, 10cm high
C. 2cm long, 2cm wide, 6cm high
Answer:
A) Is the answer
Step-by-step explanation:
vol.=LxBxH
8x1x3=24
The dimensions that could be the box with a volume of 24 cubic centimeters are:
8cm long, 1cm wide, 3cm high
2cm long, 2cm wide, 6cm high
Options A and C are the correct answer.
We have,
To determine if the given dimensions could represent the box with a volume of 24 cubic centimeters, calculate the volume for each option and check if it matches the given volume.
Let's calculate the volume for each option:
Option A:
Length = 8 cm, Width = 1 cm, Height = 3 cm
Volume = Length × Width × Height
Volume = 8 cm × 1 cm × 3 cm
Volume = 24 cubic cm
Option A could be the dimensions of the box
Option B:
Length = 10 cm, Width = 4 cm, Height = 10 cm
Volume = Length × Width × Height
Volume = 10 cm × 4 cm × 10 cm
Volume = 400 cubic cm
Option B does not have a volume of 24 cubic cm.
Option C:
Length = 2 cm, Width = 2 cm, Height = 6 cm
Volume = Length × Width × Height
Volume = 2 cm × 2 cm × 6 cm
Volume = 24 cubic cm
Option C could be the dimensions of the box.
Therefore,
The dimensions of the box with a volume of 24 cubic centimeters are:
8cm long, 1cm wide, 3cm high
2cm long, 2cm wide, 6cm high

Select a Value
Linear
Quadratic, f(x) = x2 – 5x - 2
Exponential, Linear, y = 2x + 4, f(x) = 3.47
y = 2x + 4, Exponential
f(x) = x2 – 5x – 2, Linear
f(x) = 3.4"
Answer:
y = 2x + 4Step-by-step explanation:
The linear functions are the ones that can have at most 1 x-intercept. Specifically, slant lines and vertical lines have this characteristic.
The quadratic function doesn't have this characteristic because there are cases where it intercepts x-axis at two points (concave down).
Additionally, the exponential function doesn't have any x-intercept, because its range is restricted.
Therefore, the right asnwer is the linear function
The function that could have at most 1 x-intercept is y = 2x + 4.
What is a linear function?It is the function that can have at most 1 x-intercept. When slant lines and vertical lines should contain the attributes.
The quadratic function doesn't have this attribute since there are cases where it intercepts the x-axis at two points that represent concave down.
Moreover, the exponential function doesn't have an x-intercept, since its range is restricted.
Therefore, it should be a linear function.
