The curved surface area of a cylinder with radius of 7 cm and height of 15 cm is 259.7 cm²
What is an equation?An equation is an expression that shows how two numbers and variables are related using mathematical operations such as addition, subtraction, exponent, division and multiplication.
The curved surface area of a cylinder is:
Curved surface area = 2π * radius * height
From the image:
Radius = 7 cm, height = 15 cm, therefore:
Curved surface area = 2π * 7 cm * 15 cm = 259.7 cm²

For the two functions given, the value for f(g(8)) is option D - 24.
What is a function?
In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.
The first function is given as f(x) = x² + 2x.
The second function is given as g(x) = √(2x).
To find f(g(8)), we need to first evaluate g(8) and then plug the result into f(x).
Using g(x) = √(2x), we can find g(8).
Substitute the value of x in the equation -
g(8) = √(2(8))
g(8) = √16
g(8) = 4
Now that we know g(8) = 4, we can find f(g(8)) by plugging in 4 for x in f(x) .
Substitute the value of g(8) in the equation -
f(g(8)) = f(4)
f(g(8)) = 4² + 2(4)
f(g(8)) = 16 + 8
f(g(8)) = 24
Therefore, the solution is obtained as 24.

Step-by-step explanation:
I used my calculator and inputted everything.
given that logm 3=0.903,logm4=1.139 , and logm7=1.599, find logm4/m.
The value of logm 4/m is 1.139 - 2 logm m. This means that we can express logm 4/m in terms of other logarithmic values without finding the exact value of m.
Given that logm 3 = 0.903, logm 4 = 1.139, and logm 7 = 1.599. We are to find logm 4/m.
Using the properties of logarithm, we have,
logm 4/m = logm 4 - logm m
=1.139 - logm m .....................................(1)
Again, using the properties of logarithm, we know that:
logm 4 = logm (2 × 2)
= logm 2 + logm 2
= 1.139 = 2logm 2 ..................................(2)
Substituting equation (2) into (1) gives:
logm 4/m = 2logm 2 - logm
m = 2logm (2/m) ..................................................(3)
Using the property of logarithm once again, we know that:
loga b = logc b / logc a ............................................(4)
Substituting equation (4) into equation (3), we have:
logm 4/m = 2 logm 2 - logm
m= logm [(2/m)² / m] .............................................(5)
Now, we are to find logm 4/m by substituting the given values.
Using equation (2), we have:
logm 2 = (1.139)/2
= 0.5695
Using equation (5), we get:
logm 4/m = logm [(2/m)² / m]
logm 4/m = logm [4/m²m]
logm 4/m = logm 4 - logm
logm 4/m = 1.139 - 2 logm m
Therefore, by using the properties of logarithm, we have found that logm 4/m = 1.139 - 2 logm m. This means that we can express logm 4/m in terms of other logarithmic values without finding the exact value of m.

what is the electron domain charge cloud geometry of brf5
The electron domain charge cloud geometry of \(BrF_5\) is trigonal bipyramidal.
To determine the electron domain charge cloud geometry of \(BrF_5\), we need to examine the number of electron domains around the central atom (Br).
\(BrF_5\) consists of one central bromine atom (Br) surrounded by five fluorine atoms (F). Each bond and lone pair of electrons represents an electron domain.
In \(BrF_5\), there are five bonding pairs (Br-F) and no lone pairs around the central bromine atom. Therefore, the total number of electron domains is five.
Based on this information, the electron domain charge cloud geometry of \(BrF_5\) is trigonal bipyramidal.

the length of each side of a square is 3 inches more than the length of each side of a smaller square. the sum of the areas of the squares is 149 inches squared. find the length of the side of the smaller square.
The length of the side of the smaller square is 7 inches.
Let x be the length of the side of the smaller square.
The length of each side of a square is 3 inches more than the length of each side of a smaller square. Thus the length of the side of the larger square is
(x + 3) inches.
The area of the smaller square is
x^2 square inches.
The area of the larger square is
(x + 3)^2 square inches.
We can set up the equation:
x^2 + (x + 3)^2 = 149
Expanding and simplifying the equation gives:
x^2 + x^2 + 6x + 9 = 149
Combining like terms:
2x^2 + 6x - 140 = 0
Using the quadratic formula, we can solve for x:
x = (-b ± √(b^2 - 4ac)) / 2a
x = (-6 ± √(6^2 - 4 * 2 * (-140))) / 2 * 2
x = (-6 ± √(36 + 1120)) / 4
x = (-6 ± √(1156)) / 4
x = (-6 ± √(596)) / 4
x = (-6 ± 34) / 4
x = -10 or x = 7
The side length of the smaller square can't be negative, so x = 7 inches.

Answer:
x - y = 14x - 2y = 3x = 25Step-by-step explanation:
Given the difference of x and y is 14, and the difference of x and 2y is 3, you want two equations, their graph, and the value of x.
EquationsThe difference of 'a' and 'b' is (a -b). Here, the two differences are expressed as the equations ...
x - y = 14x - 2y = 3GraphThe attachment shows a graph of these equations. Their point of intersection is (25, 11), meaning the value of x is 25.
The graph of the first equation is easily drawn by recognizing the x- and y-intercepts are 14 and -14, respectively.
The graph of the second equation will go through the x-intercept point of (3, 0) and the y-intercept point of (0, -3/2). It is probably easier to graph this by hand by considering the x-intercept point and the slope of 1/2.
Algebraic solutionSince we're only interested in the value of x, it is convenient to eliminate the variable y. We can to that by subtracting the second equation from twice the first:
2(x -y) -(x -2y) = 2(14) -(3)
x = 25 . . . . . . . . . simplify
A 330 ml bottle of mineral water costs $0.42. A 1.5 litre bottle of the same water costs $1.65.
Which bottle is better value for money?
Answer:
Not much of a difference but the second bottle is the best buy
Step-by-step explanation:
1) Make sure that all corresponding units are the same.
Litres to millilitres
1.5 L x 1000 = 1500 ml
2) Find out how much you are paying for 1 ml for each bottle
a) First bottle
330 ml = $0.42
1 ml = x
330x = 0.42
x = 0.42/330
x = 0.0013

This is incorrect. 2p cannot be added with 6 because they are different terms: one with a variable, and one without anything. He should've continued the process of isolating p, the variable, by subtracting 6 from both sides, having:

for a goodness-of-fit test for a distribution with 7 categories, what are the degrees of freedom for the distribution for this test?
The degrees of freedom for a goodness-of-fit test with 7 categories is 6, and this value is used to determine the critical value for the chi-square test statistic.
The degrees of freedom (df) for a goodness-of-fit test with k categories is calculated as (k-1), where k represents the number of categories or groups being compared. Therefore, for a goodness-of-fit test with 7 categories, the degrees of freedom would be 6.
The goodness-of-fit test is a statistical test that assesses whether a set of observed data fits a particular theoretical distribution. The test involves comparing the observed frequencies of data in each category with the expected frequencies based on the theoretical distribution. The chi-square test is commonly used for this purpose.
The degrees of freedom in a chi-square goodness-of-fit test are important because they determine the critical value of the test statistic. The critical value is compared to the calculated chi-square value to determine whether the observed data fits the theoretical distribution.
If the calculated chi-square value is greater than the critical value, then the observed data does not fit the theoretical distribution and the null hypothesis is rejected. If the calculated chi-square value is less than the critical value, then the observed data fits the theoretical distribution and the null hypothesis is not rejected.
