Rounding to the nearest hundredth, the diameter of the sphere is approximately 4.26 cm.
What is the diameter of the sphere?A sphere is simply a three-dimensional geometric object that is perfectly symmetrical in all directions.
The surface area of a sphere is expressed as:
S = 4πr²
Where S is the surface area and r is the radius of the sphere.
Given that surface area of 18.2π cm²
We can solve for the radius as follows:
S = 4πr²
r = √( S / 4π )
r = √( 18.2π / 4π )
r = 2.13 cm
The diameter of the sphere is twice the radius, so:
d = 2r
d = 2( 2.13cm )
d = 4.26 cm
Therefore, the diameter of the sphere is 4.26 cm.

Answer:
(b) 10; 150°
Step-by-step explanation:
You want the polar coordinate equivalent of (-5√3, -5).
ConversionThe polar form of (a, b) is ...
(a, b) = (r; θ)
where ...
r = √(a² +b²)
θ = arctan(b/a) . . . . . with attention paid to quadrant
ApplicationFor the given values, the polar form is ...
r = √((-5√3)² +5²) = √(75 +25) = 10
θ = arctan(5/(-5√3)) = arctan(-1/√3) = 150°
The angle is a quadrant II angle with a reference angle of 30°.
The polar form is (10; 150°).

Differentiate y = x^3 ln 2x/e^x Sin x
Differentiating y = x^3 ln 2x/e^x Sin x is: y' = x^2 [(3 ln 2x/e^x Sin x + 3/x) - 2 ln 2x/e^x Sin x cos x + cos x].
What is Differentiation?Differentiate y can be find using the product and chain rule.
Using the chain rule
v'(x) = [1/(2x/e^x)] * (2e^x - e^x*2x) / (2x/e^x)^2
v'(x) = [e^x(2-e^x)] / (2x)^2
Using the product rule
y' = 3x^2 ln(2x/e^x) sin(x) + x^3 [e^x(2-e^x)] / (2x)^2 sin(x) + x^3 ln(2x/e^x) cos(x)
Simplifying
y' = 3x^2 ln(2x/e^x) sin(x) + (x/2) [2-e^x] sin(x) + x^3 ln(2x/e^x) cos(x)
So,
derivative of y is:
y' = 3x^2 ln(2x/e^x) sin(x) + (x/2) [2-e^x] sin(x) + x^3 ln(2x/e^x) cos(x)
Therefore the differentiate of y is 3x^2 ln(2x/e^x) sin(x) + (x/2) [2-e^x] sin(x) + x^3 ln(2x/e^x) cos(x).

The order will be $50.4 with the price increase
How much would the order be with the price increase?From the question, we have the following parameters that can be used in our computation:
Order = $45
Percentage increase = 12%
Using the above as a guide, we have the following:
New order = Order * (1 + Percentage increase)
Substitute the known values in the above equation, so, we have the following representation
New order = 45* (1 + 12%)

Mona pays $1.00 for the first call of the day on her mobile phone plus $0.15 per minute of the call. She paid $2.95 for her first call today. Write an expression that you could use to calculate the length in minutes of the phone call.
The requreid Mona's phone call was 13 minutes long.
Let's let the variable "m" represent the length of the phone call in minutes.
We know that Mona pays $1.00 for the first call of the day plus $0.15 per minute of the call. So the total cost of the call can be represented by the expression:
$1.00 + $0.15m
We also know that Mona paid $2.95 for her first call today. So we can set the expression for the total cost of the call equal to $2.95:
$1.00 + $0.15m = $2.95
To solve for the length of the call in minutes, we can first subtract $1.00 from both sides of the equation:
$0.15m = $1.95
Then we can divide both sides by $0.15:
m = 13
Therefore, Mona's phone call was 13 minutes long.

Water is 2parts of hydrogen and 1 part of oxygen. For one molecule of water, each atom has the atomic mass unit of u, shown. What percent of the mass of a water molecule is hydrogen
Oxygen=16.00u
Hydrogen = 1.01u
11.2% of the mass of a water molecule is hydrogen
How to solve for the percentageAs water is composed of two parts hydrogen and one part oxygen, the total mass of a single molecule may be determined by ascertaining the following:
The Total Mass of Water = (2 x Mass of Hydrogen) + (1 x Mass of Oxygen)
Total Mass of Water = (2 x 1.01u) + (1 x 16.00u)
Total Mass of Water = 18.02u
Consequently, the overall mass of one molecule of water is determined to be 18.02 atomic mass units (u).
% mass of hydrogen = (mass of hydrogen / total mass of water) × 100
% mass of hydrogen = (2.02u / 18.02u) × 100

Triangles ABC and DEF are mathematically similar. 9 Cm B The area of triangle ABC is 34 cm. Calculate the area of triangle DEF. F 13.5 cm
Answer:
Since the triangles are similar, their corresponding sides are in proportion. The ratio of sides AB to DE is 9:13.5, which simplifies to 2:3. Therefore, the ratio of their areas is the square of the ratio of their sides, which is 4:9.
If the area of triangle ABC is 34 cm, then the area of triangle DEF is:
Area of DEF = (Area of ABC) x (DE^2/AB^2) = 34 x (13.5^2/9^2) = 34 x 1.5^2 = 34 x 2.25 = 76.5 cm^2
Therefore, the area of triangle DEF is 76.5 cm^2.

Answer:16x-4-2x+8=14x+4
Step-by-step explanation:
In order to solve this question you first want to multiply everything inside the bracket by the number outside.
4(4x-1)
so 4 times 4x which is 16x and 4 times -1 which is -4 so the first bracket is
(16x-4)
then do the same for the second bracket
-2(x-4)
so -2 times x would be -2x and -2 times -4 would be 8
for the final step collect the like terms and solve
so your answer would be
16x-2x which would be 14x and -4+8 which would be 4
so in conclusion the answer is

use the product to rewrite log16(256b)
Log₁₆(256b) in terms of the logarithm of b, which is the factor that was multiplied by 256 inside the logarithm is 2 + log₁₆(b)
We can use the product rule of logarithms, which states that the logarithm of a product is equal to the sum of the logarithms of the factors.
Therefore, we can write
log₁₆(256b) = log₁₆(256) + log₁₆(b)
We can simplify log₁₆(256) as follows:
log₁₆(256) = log₁₆(16^2) = 2
Therefore, we have:
log₁₆(256b) = log₁₆(256) + log₁₆(b)
= 2 + log₁₆(b)
So, we have rewritten log₁₆(256b) in terms of the logarithm of b, which is the factor that was multiplied by 256 inside the logarithm.

Give two pairs of polar coordinates for the point (0, -10)
The required two pairs of polar coordinates for the point (0, -10) are:
(10, π/2) and (10, -π/2)
To convert from Cartesian coordinates (x, y) to polar coordinates (r, θ), we can use the following formulas:
[tex]r = \sqrt{(x^2 + y^2)}\\\theta = \tan^{-1}(y/x)[/tex]
Since the x-coordinate of the point (0, -10) is 0, we can directly say that the angle θ is either π/2 or -π/2, depending on whether y is positive or negative.
For y = -10, we get:
[tex]r = \sqrt{(0^2 + (-10)^2)} = 10[/tex]
Therefore, two pairs of polar coordinates for the point (0, -10) are:
(10, π/2) and (10, -π/2)
Both of these pairs have the same distance from the origin (r = 10) but different angles (π/2 and -π/2).

To factor the expression x^2 - 14 - 4x, we can use the technique of grouping.
First, we can rearrange the terms as:
x^2 - 4x - 14
Next, we can factor out a common factor of x from the first two terms:
x(x - 4) - 14
Then, we can factor out a negative 1 from the last two terms:
x(x - 4) - 1(14)
Finally, we can write the expression as the product of two binomials:
(x - 4)(x - 14)
Therefore, the factored form of x^2 - 14 - 4x is (x - 4)(x - 14).

Find the value of
n so that the line that goes through the points
(8,n) and
(2,−2) is perpendicular to
y=2x+4.
Answer:
n = -5
Step-by-step explanation:
We know that when two lines are perpendicular, the slopes of the two lines are negative reciprocals as
[tex]m_{2}=-\frac{1}{m_{1} }[/tex], where m2 is the slope of the line we're usually not given, and m1 is the slope of the line we're given
Thus, we know that m2 must equal -1/2 from the formula since m1 is 2:
[tex]m_{2}=-\frac{1}{2}[/tex]
Of course, -1/2 is already simplified so m2 is the slope of the line passing through (8, n) and (2, -2)
To find n, we must use our knowledge of the slope formula that gives us the slope, m:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex], where x1 and y1 are one point on the line and x2 and y2 are another point on the line:
If we allow (8, n) to be our x1 and y1 point and allow (2, -2) to be our x1 and y2 point and -1/2 to be our m, we can now solve for m by plugging everything into the slope formula and solving for n (aka y1 in the formula:
[tex]-1/2=\frac{-2-n}{2-8}\\ \\-1/2=\frac{-2-n}{-6}\\ \\3=-2-n\\\\5=-n\\\\-5=n[/tex]
We can even check that we get -1/2 when we plug in -5 into the slope formula:
[tex]-1/2=(-2-(-5))/(2-8)\\-1/2=(-2+5)/(-6)\\-1/2=3/-6\\-1/2=-1/2[/tex]
