Question 25 Given that a: b = 8:5 and b: c = 3:4, find the ratio a: b: c Give your answer in its simplest form.
Answer:
24 : 15 : 20
Step-by-step explanation:
express ratios in fractional form and express b and c in terms of a
\(\frac{a}{b}\) = \(\frac{8}{5}\) ( cross- multiply )
8b = 5a ( divide both sides by 8 )
b = \(\frac{5}{8}\) a
also
\(\frac{b}{c}\) = \(\frac{3}{4}\) ( cross- multiply )
3c = 4b ( divide both sides by 3 )
c = \(\frac{4}{3}\) b = \(\frac{4}{3}\) × \(\frac{5}{8}\) a = \(\frac{5}{6}\) a
Then
a : b : c
= a : \(\frac{5}{8}\) a : \(\frac{5}{6}\) a ( multiply each part by 24, the LCM of 8 and 6 )
= 24a : 15a : 20a ( divide each part by a )
= 24 : 15 : 20 ← in simplest form

The length of side x is approximately 24.87, rounded to the nearest hundredth.
how can we find side of the triangle?
To find the length of side x, we can use the sine function, which relates the opposite side to an angle to the hypotenuse:
sin(11°) = opposite side/hypotenuse
Rearranging this equation, we get:
opposite side = sin(11°) * hypotenuse
We know that the hypotenuse has a length of 130, so we can substitute that in:
opposite = sin(11°) * 130
Using a calculator, we can evaluate sin(11°) to be approximately 0.1919, so we can substitute that in as well:
opposite = 0.1919 * 130
Simplifying this expression, we get:
opposite ≈ 24.87
Therefore, the length of side x is approximately 24.87, rounded to the nearest hundredth.

Answer: $130 money did Brenda and Hazel have all together before buying decorations and snacks.
Here, we have,
You want to know Brenda and Hazel's combined money when the ratio of their remaining balances is 1 : 4 after Brenda spent $58 and Hazel spent $37. They had the same amount to start with.
Setup
Let x represent the total amount the two women started with. Then x/2 is the amount each began with, and their fnal balance ratio is ...
(x/2 -58) : (x/2 -37) = 1 : 4
Solution
Cross-multiplying gives ...
4(x/2 -58) = (x/2 -37)
2x -232 = x/2 -37 . . . . . . eliminate parentheses
3/2x = 195 . . . . . . . . . . . . add 232-x/2
x = (2/3)(195) = 130 . . . . . multiply by 2/3
Brenda and Hazel had $130 altogether before their purchases.
Alternate solution
The difference in their spending is $58 -37 = $21.
This is the same as the difference in their final balances.
That difference is 4-1 = 3 "ratio units", so each of those ratio units is $21/3 = $7.
Their ending total is 1+4 = 5 ratio units, or $35.
The total they started with is $58 +37 +35 = $130.

What of the following is not a vertical asymptote of the function

Rewrite the function as
\(f(x) = \dfrac{\tan(\left(\frac{\pi x}4\right)}{x^2 - 8x + 15} = \dfrac{\sin\left(\frac{\pi x}4\right)}{\cos\left(\frac{\pi x}4\right) (x-3) (x-5)}\)
Vertical asymptotes occur wherever the denominator is zero (but not necessarily when the numerator is also zero).
We have
\(\cos\left(\dfrac{\pi x}4\right) (x-3) (x-5) = 0\)
\(\implies \cos\left(\dfrac{\pi x}4\right) = 0 \text{ or } x - 3 = 0 \text{ or } x - 5 = 0\)
In the first case, we have
\(\cos\left(\dfrac{\pi x}4\right) = 0 \implies \dfrac{\pi x}4 = \pm\dfrac\pi2 + 2n\pi \implies x = \pm 2 + 8n\)
where \(n\) is an integer. That is, any of \(x\in\{\ldots,-10,-2,\boxed{6},14,\ldots\}\) and \(x\in\{\ldots,-6,\boxed{2},10,18,\ldots\}\) are asymptotes.
In the latter two cases, we get \(x=\boxed{3}\) or \(x=\boxed{5}\). The numerator is finite at these values \(\left(\sin\left(\frac{3\pi}4\right)=\frac1{\sqrt2}\text{ and } \sin\left(\frac{5\pi}4\right)=-\frac1{\sqrt2}\right)\).
This means \(x=4\) is not an asymptote. (C)

In any year, the weather can inflict storm damage to a home. From year to year, the damage is random. Let Y denote the dollar value of damage in any given year. Suppose that in 95% of the years Y = $0, but in 5% of the years Y = $20,000.
A. The mean of the damage in any year is $__. nothing. The standard deviation of the damage in any year is $____.
B. Consider an "insurance pool" of 100 people whose homes are sufficiently dispersed so that, in any year, the damage to different homes can be viewed as independently distributed random variables. Let barY denote the average damage to these 100 homes in a year. The expected value of the average damage barY, is $____. The probability that exceeds $is____.
Answer:
a. mean = 1000
standard deviation = 4358.9
b. expected value of average damage bar Y = 1000
probability bar y exceeds 2000 = 0.011
Step-by-step explanation:
we have p1 = 95%, y1 = 0, p2 = 5%, y2 = 20000
Mean = (0.95 * 0) + (0.05 * 20000)
= 1000
var(y) = E(y²) - E(Y)²
= we solve for E(y)²
= 0²*0.95 + 20000²*0.05
= 0 + 20000000
then the variance of y = 20000000 - 1000²
=20000000-1000000
= $19000000
standard deviation is the square root of variance
= √19000000
= 4358.9
2.
a. Expected value of average is also the mean = 1000
b. we are to find probability that barY exceeds 2000
\(z=\frac{2000-1000}{\sqrt{19000000/100} }\)
= 1000/435.889
= 2.29
1-p(z≤2.29)
= 1 - 0.989
= 0.011
so the probability that barY exceeds 2000 is 0.011
A function y = g(x) is graphed below. What is the solution to the equation g(x) = 3?
Answer:
See below.
Step-by-step explanation:
From the graph, we can see that g(x)=3 is true only when x is between 3 and 5. However, note that when x=3, the point is a closed circle. When x=5, the point is an open circle. Therefore, the solution is between 3 and 5, and it includes 3 but not 5.
In set-builder notation, this is:
\(\{x|x\in \mathbb{R}, 3\leq x<5\}\)
In interval notation, this is:

Essentially, these answers are saying: The solution set for g(x)=3 is all numbers between 3 and 5 including 3 and not including 5.

The transformations taking place in the given function is a horizontal left ward shift of 9 units and 1 unit upward vertical shift.
What is transformation?A Transformation in Math is a process of moving an object (two-dimensional shape) from its original position to a new position.
Given that, a function f(x) undergo some transformations to become f(x+9)-1,
We know that,
Vertical Shifting:
Adding a constant to a function will shift its graph vertically (i.e. y = f (x) + c). Adding a positive constant c will shift the graph upward c units, while adding a negative constant c will shift it downward c units.
Horizontal Shifting:
Horizontal shifts are inside changes that affect the input (x-) axis values and shift the function left or right. Combining the two types of shifts will cause the graph of a function to shift up or down and right or left.
Therefore, there is transformation of a horizontal and vertical shift.
Hence, the transformations taking place in the given function is a horizontal left ward shift of 9 units and 1 unit upward vertical shift.

You are given the great circle of a sphere is a length of 25 miles. What is the volume of the sphere
The volume of the sphere is approximately 3431.82 cubic miles.
To find the volume of a sphere, we need the radius of the sphere. The length of a great circle is the circumference of the sphere, which is related to the radius by the formula C = 2πr, where C is the circumference and r is the radius.
In this case, we are given that the length of the great circle is 60 miles. We can use this information to find the radius of the sphere.
C = 2πr
60 = 2πr
Divide both sides of the equation by 2π:
r = 60 / (2π)
r = 30 / π
Now that we have the radius, we can use the formula for the volume of a sphere:
V = (4/3)πr³
V = (4/3)π(30/π)³
V = (4/3)π(27000/π³)
V = (4/3)π(27000/π³)
V = (4/3)π(27000/π³)
V = (4/3)(27000/π²)
V = (4/3)(27000/9.87) (approximating π to 3.14)
V ≈ 3431.82 cubic miles
Therefore, the volume of the sphere is approximately 3431.82 cubic miles.

The Centers for Disease Control reported the percentage of people 18 years of age and older who smoke (CDC website, December 14, 2014). Suppose that a study designed to collect new data on smokers and nonsmokers uses a preliminary estimate of the proportion who smoke of .30. a. How large a sample should be taken to estimate the proportion of smokers in the population with a margin of error of .02 (to the nearest whole number)
Answer:
A sample of 2017 people should be taken.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.
\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)
In which
z is the zscore that has a pvalue of \(1 - \frac{\alpha}{2}\).
The margin of error is:
\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)
Suppose a 95% confidence level:
So \(\alpha = 0.05\), z is the value of Z that has a pvalue of \(1 - \frac{0.05}{2} = 0.975\), so \(Z = 1.96\).
Preliminary estimate of the proportion who smoke of .30.
This means that \(\pi = 0.3\)
a. How large a sample should be taken to estimate the proportion of smokers in the population with a margin of error of .02 (to the nearest whole number)
This is n for which M = 0.02. So
\(M = z\sqrt{\frac{\pi(1-\pi)}{n}}\)
\(0.02 = 1.96\sqrt{\frac{0.3*0.7}{n}}\)
\(0.02\sqrt{n} = 1.96\sqrt{0.3*0.7}\)
\(\sqrt{n} = \frac{1.96\sqrt{0.3*0.7}}{0.02}\)
\((\sqrt{n})^2 = (\frac{1.96\sqrt{0.3*0.7}}{0.02})^2\)
\(n = 2016.84\)
To the nearest whole number, 2017.

Step-by-step explanation:
Gross income= $813.61
Giving the following information:
Sales= $32,874
Fixed salary= $452
Commission= 1.1% paid on sales in excess of $25,000.
To calculate the gross income, we need to use the following formula:
Gross income= 452 + y*x
y= percentage comission
x= sales
For $32,874 sales:
Gross income= 452 + 0.011*32,874
Gross income= $813.61

The function\(f(x)\) is continuous at \(x = -1.\)
We must demonstrate the following to establish that the function \(f(x) = (x+3x5)4\) is continuous at \(a=-1\)
if\(x -1\), then\(f(x) = f (-1)\)
\(f(-1) = (-1 + 3(-1)^5)^4 = (-1 - 3)^4 = 16\)
The phrase \(lim x -1\)f can then be made simpler using the properties of limits (x). The formula for binomial expansion allows us to express \(f(x)\) as follows:
\(f(x)=x4 + 12 + 9 + 54 + 13 + 108 + 81\)
Next, we have
\(lim x → f(x) = -1 lim x (x4 + 12x9 + 54x13 + 108x17 + 81x21) - 1 = lim x -1 x^4 + lim x → -1 12x^9 + lim x → -1 54x^13 + lim x → -1 108x^17 + lim x → -1 81x^21 \s= (-1) (-1) ^4 + 12(-1)^9 + 54(-1)^13 + 108(-1)^17 + 81(-1)^21 \s= 1 - 12 + 54 - 108 + 81 \s= 16\)

The domain of function A and function B are compared by the statement of Option A: The domain of Function A is the set of real numbers greater than 0. The domain of Function B is the set of real numbers greater than or equal to 1.
What is a function?
A function is a fundamental concept in mathematics that relates a set of inputs (also known as the domain) to a corresponding set of outputs (sometimes referred to as the codomain). For each input, there exists exactly one output, and the output can be linked to its corresponding input in a unique manner.
The domain of a function refers to the set of all possible input values for which the function can produce an output.
In Function A, the domain consists of all real numbers greater than 0, since it is a logarithmic function that can take any positive number as an input.
In contrast, the domain of Function B includes all real numbers greater than or equal to 1, since it is a square root function that begins at (1,0) and continues to infinity.
This means that any number greater than or equal to 1 can be used as an input to produce a corresponding output.
It is essential to define the domain of a function accurately to ensure that the function is well-defined and to avoid potential errors or ambiguities in mathematical computations.
Therefore, the correct statement is A.

What is simple intresst?Simple interest is the type of interest that is calculated on the principal amount only.
It is a fixed percentage of the principal amount that is charged or earned over a certain period of time, without any compounding of interest.
(a) The total amount they ended up paying for the townhome is the sum of the down payment and the total amount of the mortgage payments.
Down payment = $41,000
Total amount of mortgage payments = monthly payment x number of payments = $2675.04 x 12 months/year x 15 years = $482,906.40
Total amount paid = down payment + total amount of mortgage payments = $41,000 + $482,906.40 = $523,906.40
(b) The amount of interest paid on the mortgage can be calculated by subtracting the principal (the amount borrowed) from the total amount paid.
Principal = Total cost of townhome - Down payment = $358,000 - $41,000 = $317,000
Total interest paid = Total amount paid - Principal = $523,906.40 - $317,000 = $206,906.40

Answer:
The answer is (f.g)(x) = 12x^2 - 9.
Step-by-step explanation:
To find (f.g)(x), we need to apply the composition of functions formula, which is:
(f.g)(x) = f(g(x))
First, we need to find g(x):
g(x) = 3x^2
Now, we need to plug g(x) into f(x) in place of x:
f(g(x)) = 4(g(x)) - 9
= 4(3x^2) - 9
= 12x^2 - 9
Therefore, (f.g)(x) = 12x^2 - 9.
