What is the height, in meters, of a cylinder with surface area 104π m2 and radius 4 m?
PLEASE SOMONE HELP
The height h of the cylinder is 9 meters.
What is the height of the cylinder?A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
The surface area of a cylinder is expressed as;
Surface Area = 2πrh + 2πr²
Given that; the surface area is 104π m² and the radius as 4 m.
We need to solve for the height (h).
Plug the values into the above formula:
Surface Area = 2πrh + 2πr²
104π = 2πrh + 2πr²
104π = 2π( rh + r² )
Divide through by 2π
52 = rh + r²
52 = ( 4 × h) + ( 4² )
52 = 4h + 16
Subtract 16 from both sides
52 - 16 = 4h + 16 - 16
52 - 16 = 4h
36 = 4h
4h = 36
h = 36/4
h = 9 meters
Therefore, the height is 9 meters.

Convert from radians to degrees.
1/4π
1/4π radians is approximately equal to 45 degrees.
To convert a value from radians to degrees, multiply the value by 180/π. For example, to convert π/4 radians to degrees, multiply π/4 by 180/π to get 45 degrees. This conversion is useful for converting angles between the two units of measurement.
Degrees = Radians × 180/π.
Therefore, to convert 1/4π radians to degrees, we have:
Degrees = (1/4π) × (180/π) ≈ 45°
Hence, 1/4π radians is approximately equal to 45 degrees.

Following a translation of (x, y) (x - 1, y + 2) and a dilation by a scale factor of 2 centred at the origin, the coordinates of T are T''(8, 8).
Following translation and dilation, we must take the following actions to determine the new coordinates of point T:
1) Translation: (x, y) = (x - 1, y + 2).
T' = (5 - 1, 2 + 2)
= (4, 4) applies the translation to the original coordinates of T.
2) Dilation: Scale factor of 2 centered at the origin
Multiply the translated coordinates by the scale factor of 2:
T'' = (2 × 4, 2 × 4)
= (8, 8)
Therefore, the coordinates of T after the translation (x, y) → (x - 1, y + 2) followed by a dilation by a scale factor of 2 centered at the origin are T''(8, 8).

principal $45,687.23 annual interest rate 7.555% interest period monthly. What is the first period interest?
The interest rate for the first period is $287.22
Using the Simple Interest PrincipleTo obtain the first period interest, we use simple interest formula;
Simple Interest = Principal * Rate * Time
Given:
Principal = $45,687.23
Annual interest rate = 7.555%
Interest period = Monthly
Convert the annual interest rate to a monthly interest rate.
Monthly interest = Annual interest/ 12 = 7.555/12 = 0.6295%
First period interest:Interest = Principal * Monthly interest rate * Time
Since it's the first period, the time is 1 month:
Interest = $45,687.23 * 0.62958333% * 1
Interest = $45,687.23 * 0.0062958333
Interest ≈ $287.22
Therefore, the first period interest is $287.22.

After 1 year = £2630.00
After 2 years = £2766.76
a) What is the rate of interest per annum? Give your answer as a percentage to 1 d.p.
b) Work out the value of the loan 10 years after it starts. Give your answer in pounds (£) to the nearest 1p.
The rate is 5.2%
After 10 years, the money will amount to £4150.
What is compound interest?We know that the compound interest can be obtained from;
[tex]A = P(1 + r/n)^{nt}[/tex]
The rate is obtained from;
I = A - P
I = interest
A = amount
P = principal
r = rate
n = Number of times compounded
t = time in years
Then;
I = £2630.00 - £2500.00
I = £130
I = PRT/100
130 = 2500 * R * 1/100
R = 130 * 100/2500
R = 5.2%
After 10 years;
[tex]A = 2500 ( 1 + 0.052)^{10}[/tex]

PLS HELP! What is the domain and Rage of the given below?
And is it a Function or not?
X /-2/-2 /-1 /-1 /0
Y/ 5/-5/ 3/-3/-1
In Functions and Function Notation, we were introduced to the concepts of domain and range. In this section we will practice determining domains and ranges for specific functions. Keep in mind that, in determining domains and ranges, we need to consider what is physically possible or meaningful in real-world examples, such as tickets sales and year in the horror movie example above. We also need to consider what is mathematically permitted. For example, we cannot include any input value that leads us to take an even root of a negative number if the domain and range consist of real numbers. Or in a function expressed as a formula, we cannot include any input value in the domain that would lead us to divide by 0.
Diagram of how a function relates two relations.
We can visualize the domain as a “holding area” that contains “raw materials” for a “function machine” and the range as another “holding area” for the machine’s products.
We can write the domain and range in interval notation, which uses values within brackets to describe a set of numbers. In interval notation, we use a square bracket [ when the set includes the endpoint and a parenthesis ( to indicate that the endpoint is either not included or the interval is unbounded. For example, if a person has $100 to spend, he or she would need to express the interval that is more than 0 and less than or equal to 100 and write
(
0
,
100
]
. We will discuss interval notation in greater detail later.
Let’s turn our attention to finding the domain of a function whose equation is provided. Oftentimes, finding the domain of such functions involves remembering three different forms. First, if the function has no denominator or an even root, consider whether the domain could be all real numbers. Second, if there is a denominator in the function’s equation, exclude values in the domain that force the denominator to be zero. Third, if there is an even root, consider excluding values that would make the radicand negative.
Before we begin, let us review the conventions of interval notation:
The smallest term from the interval is written first.
The largest term in the interval is written second, following a comma.
Parentheses, ( or ), are used to signify that an endpoint is not included, called exclusive.
Brackets, [ or ], are used to indicate that an endpoint is included, called inclusive.

Option D is the correct answer.
We have,
A pure imaginary number is a number that does not have a real part and can be written in the form of bi, where b is a real number and i is the imaginary unit (√(-1)).
We have,
[tex]3i^5 + i (2 - 4i^3) - 2 (-3 + i)[/tex]
In this expression, we can simplify and rewrite it as:
[tex]3i^5 + i(2 - 4i^3) + 6 - 2i[/tex]
Now, let's evaluate the powers of i:
[tex]i^5 = i^{4 + 1} = i^4 \times i = 1 \times i = i\\i^3 = i^{2 + 1} = i^2 \times i = (-1) \times i = -i[/tex]
Substituting these values back into the expression:
[tex]3i^5 + i(2 - 4i^3) + 6 - 2i = 3i + i(2 - 4(-i)) + 6 - 2i[/tex]
= 3i + i(2 + 4i) + 6 - 2i
= 3i + 2i + 4i² + 6 - 2i
= 3i + 2i + 4(-1) + 6 - 2i
= 5i - 4 + 6 - 2i
= 5i - 2i - 4 + 6
= 3i + 2
The expression 3i + 2 represents a pure imaginary number, as it has no real part (the constant term is 2 and does not involve the imaginary unit i).
Thus,
The expression that represents a purely imaginary number is:

Answer:
(-6,0)
Step-by-step explanation:
An equation of a line can be modeled as y = mx + b where m is slope and b is y-intercept.
For the line r, we can model the equation as y = mx + 3 since the line intersects y-axis at (0,3) as seen in the attachment.
For the line t, we can model the equation as y = mx - 6 as the problem gives y-intercept for line t equal to -6. Hence, the line t intersects y-axis at (0,6)
Next, we have to find the slope of line t by finding the slope of line r in the attachment. Apply the rise over run by counting the steps, you can see in the attachment that I put to learn how to count rise and run of a line. Also note that the value in attachment here is a scalar quantity, meaning only magnitude, no direction.
So we will have the slope of -1 since a line graph is heading down so the output decreases as input increases. Therefore, we know that m = -1 for both lines. Therefore, for the line t, we can model the new equation to:
[tex]\displaystyle{y=-x-6}[/tex]
Then we find the x-intercept of the line by letting y = 0. Thus,
[tex]\displaystyle{0=-x-6}\\\\\displaystyle{x=-6}[/tex]
Therefore, the x-intercept of line t is at (-6,0).
Answer:
(-6,0)
Step-by-step explanation:
We need to determine the equation of line r first to find the x-intercept of line t.
The slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by the formula:
[tex]slope = \frac{y_2 - y_1}{x_2 -x_1}[/tex]
For line r passing through (3, 0) and (0, 3), the slope is:
[tex]slope = \frac{3 - 0}{0 - 3} = -1[/tex]
Since line t has the same slope as line r, its slope is also -1.
The equation of a line in slope-intercept form (y = mx + b) is determined by its slope (m) and y-intercept (b).
We know that the slope (m) of line t is -1, and the y-intercept (b) is -6. Substituting these values into the slope-intercept form, we get:
y = -x - 6
To find the x-intercept, we set y = 0 and solve for x:
0 = -x - 6
Adding x to both sides:
x = -6
Therefore, the x-intercept of line t is (-6,0).
