Identify the graph of 4+2i. Is the point at (2,4), (4,2), (4,-2), or (-4,2)?
Answers
The graph of the complex number 4 + 2i corresponds to the point (4, 2) on the complex plane, with 4 as the real part and 2 as the imaginary part.
To identify the graph of the complex number 4 + 2i, you can think of it as a point on the complex plane. In the complex plane, the horizontal axis represents the real part of a complex number, and the vertical axis represents the imaginary part. So, for the complex number 4 + 2i, the real part is 4, and the imaginary part is 2.
Now, let's locate this point on the complex plane:
The real part (4) corresponds to the horizontal axis.
The imaginary part (2) corresponds to the vertical axis.
So, the point (4, 2) on the complex plane represents the complex number 4 + 2i. Therefore, the correct answer is (4, 2).
In summary, the graph of the complex number 4 + 2i corresponds to the point (4, 2) on the complex plane, where 4 is the real part, and 2 is the imaginary part.

A. always
B. sometimes
c never
Answers
Answer:
never
Step-by-step explanation:
In a 30 - 60 - 90 degree triangle , the common ratio is
1 : [tex]\sqrt{3}[/tex] : 2
Shorter leg that is opposite to 30 degree = 1
Longer leg that is opposite to 60 degree = [tex]\sqrt{3}[/tex]
Hypotenuse is opposite to 90 degree = 2
Shorter leg is half the length of the hypotenuse as per the ratio
Long leg is never the half of the hypotenuse

The number "2.8 x 10^3" turns into "3 x 10^3"

There are 1000 three digit locker combinations are possible if the digits are able to repeat.
The correct option is B.
If the digits are able to repeat, there are 10 options for each digit (0-9) in a three-digit combination.
Since each digit can be chosen independently, the total number of different three-digit combinations is given by:
Number of combinations
= Number of options for the first digit x Number of options for the second digit x Number of options for the third digit

Simplify the expression:
sqrt(4x^2/3y)
Answers
The expression √(4x^2/3y) simplifies to (2x)/√(3y), by taking the square root of the numerator and the denominator separately.
Explanation:To simplify the expression √(4x^2/3y), we will start by simplifying the square root of a fraction, which can be done by taking the square root of the numerator and the denominator separately. We have √(4x^2) = 2x because the square root of 4 is 2 and the square root of x^2 is x. For the denominator, we have √(3y), which cannot be simplified further without additional information about y. Therefore, the simplified form of the expression is (2x)/√(3y).
Remember, if we encounter an expression with a higher root like a fourth root, we would raise the number to the 0.25 power, which is equivalent to taking the square root twice. While simplifying expressions, we may also need to solve for variables in an equation or work with fractional powers, which represent roots, such as x^2 = √x.

Answers
The expression 3x + 2 - 3x + 7 +5x simplifies to 5x
when the terms containing variable 'x' are combined. Therefore, the coefficient in the simplified expression is 5.
Explanation:The given expression is 3x + 2 – 3x + 7 +5x.
To simplify this expression, we need to combine like terms, which in this case are terms with x.
The like terms are 3x, -3x, and 5x. When added together, they simplify to: 3x - 3x + 5x = 5x.
The number part of the term, excluding x, is referred to as the coefficient. So the coefficient of x in this simplified expression is 5.

A rose garden is designed by joining a rectangle and a semicircle, as shown below. The rectangle is 24ft long and 18ft wide. If the gardener wants to build a fence around the garden, how many feet of fence are required?
Answers
Because you would add:
24 + 24 + 18 + 18 = 84ft
If you multiplied 18 by 24 you'd get area not perimeter.
♥ Hope I helped ♥
According to the given rectangle, approximately 112.27 feet of fence are required to enclose the rose garden.
The perimeter of a rectangle is the sum of all its sides. In this case, the rectangle has two sides of length 24 feet and two sides of length 18 feet.
Therefore, the perimeter of the rectangle can be calculated as follows:
Perimeter of rectangle = 2 * (Length + Width)
= 2 * (24 ft + 18 ft) = 2 * 42 ft = 84 ft.
The circumference of a circle can be calculated using the formula:
Circumference = π * Diameter.
Diameter of the Semicircle: The diameter of the semicircle is equal to the width of the rectangle, which is 18 feet.
Circumference of the Semicircle: Using the formula mentioned above:
Circumference = π * 18 ft
≈ 56.5487 ft (rounded to four decimal places).
Perimeter of the Semicircle: As it is a semicircle, we only need half of the circumference:
Perimeter of semicircle = Circumference / 2
≈ 56.5487 ft / 2 ≈ 28.2744 ft (rounded to four decimal places).
Total Fence Length Required: Now, we add the perimeter of the rectangle and the semicircle to find the total length of fence required to enclose the rose garden:
Total fence length = Perimeter of rectangle + Perimeter of semicircle
= 84 ft + 28.2744 ft ≈ 112.2744 ft (rounded to four decimal places).

To solve the problem:
Let f = distance one way distance on level ground
Let h = distance rode on the hill
Write a time equation; where Time = distance/speed:
level time + uphill time + downhill time + level time = 1hr
f/9 + h/6 + h/18 + f/9 = 1 hr
Multiply equation by 18 to get rid of the denominators
2f + 3h + h + 2f = 18
4f + 4h = 18

Which exponential function goes through the points (1, 8) and (4, 512)?
f(x) = 4(2)^x
f(x) = 8(2)^-x
f(x) = 4(4)^-x
f(x) = 2(4)^x
Answers
Answer:
Therefore, the correct option is: (C.) [tex]\( f(x) = 2 \cdot 4^x \)[/tex]
Explanation:
To determine the exponential function that passes through the given points, we can use the general form of an exponential function:
[tex]\[ f(x) = a \cdot b^x \][/tex]
Where:
[tex]\( a \)[/tex] is the initial value or the value of the function when [tex]\( x = 0 \).[/tex]
[tex]\( b \)[/tex] is the base of the exponential function.
Given the points [tex]\((1, 8)\) and \((4, 512)\)[/tex], we can substitute these coordinates into the general form and solve for [tex]\( a \) and \( b \).[/tex]
Using the point [tex]\((1, 8)\):[/tex]
[tex]\[ 8 = a \cdot b^1 \][/tex]
[tex]\[ 8 = a \cdot b \][/tex]
Using the point [tex]\((4, 512)\):[/tex]
[tex]\[ 512 = a \cdot b^4 \][/tex]
We can divide the equation obtained from the second point by the equation obtained from the first point to eliminate [tex]\( a \)[/tex] and solve for [tex]\( b \):[/tex]
[tex]\[ \frac{512}{8} = \frac{a \cdot b^4}{a \cdot b} \][/tex]
[tex]\[ 64 = b^3 \][/tex]
Taking the cube root of both sides:
[tex]\[ b = 4 \][/tex]
Now that we have found the value of [tex]\( b \)[/tex], we can substitute it back into one of the equations to find \( a \). Let's use the first point [tex]\((1, 8)\):[/tex]
[tex]\[ 8 = a \cdot 4 \][/tex]
[tex]\[ a = 2 \][/tex]
So, the exponential function that passes through the points [tex]\((1, 8)\) and \((4, 512)\)[/tex] is:
[tex]\[ f(x) = 2 \cdot 4^x \][/tex]
