Answer:
(g) D, (h) A--------------------
Part (g)'At most' means less than or equal, therefore the quotient of p and q is:
p/q ≤ 6The matching choice is D.
Part (h)'At least' means more than or equal, therefore the reciprocal of w is:
1/w ≥ 9The matching choice is A.
Answer:
g) The correct option is: p/q ≤ 6
The phrase "the quotient of p and q" means p divided by q, which is expressed as p/q. The statement "the quotient of p and q is at most 6" means that the value of p/q cannot exceed 6, but it can be less than or equal to 6. Therefore, we use the less than or equal to a symbol (≤) to represent this statement.
here is an explanation of each option:
p/q = 6: This statement indicates that the quotient of p and q is exactly 6. In other words, p/q can only be equal to 6 and not less than or greater than 6.p/q ≥ 6: This statement indicates that the quotient of p and q can be equal to 6 or greater than 6. In other words, p/q can be any value that is greater than or equal to 6.p/q > 6: This statement indicates that the quotient of p and q can be greater than 6, but not equal to 6. In other words, p/q can be any value that is greater than 6.p/q ≤ 6: This statement indicates that the quotient of p and q can be equal to 6 or less than 6. In other words, p/q can be any value that is less than or equal to 6.p/q < 6: This statement indicates that the quotient of p and q can be less than 6, but not equal to 6. In other words, p/q can be any value that is less than 6.Here's how to express each statement as an inequality in terms of 8a^2:
p/q ≤ 6:
Multiplying both sides by q, we get:p ≤ 6q
Multiplying both sides by 8a^2, we get:8a^2p ≤ 48a^2q
Therefore, the inequality for p/q ≤ 6 in terms of 8a^2 is:8a^2p ≤ 48a^2q
h) The correct option is: 1/w ≤ 9
The reciprocal of a number w is 1/w. The phrase "the reciprocal of w is at least 9" means that the value of 1/w cannot be less than 9, but it can be greater than or equal to 9. Therefore, we use the less than or equal to symbol (≤) to represent this statement.
Here's an explanation of each option:
1/w ≥ 9: This statement indicates that the reciprocal of w is greater than or equal to 9. In other words, 1/w can be any value that is greater than or equal to 9.1/w < 9: This statement indicates that the reciprocal of w is less than 9. In other words, 1/w can be any value that is less than 9.1/w ≤ 9: This statement indicates that the reciprocal of w cannot be less than 9, but it can be greater than or equal to 9. In other words, 1/w can be any value that is greater than or equal to 9.1/w > 9: This statement indicates that the reciprocal of w is greater than 9. In other words, 1/w can be any value that is greater than 9.1/w = 9: This statement indicates that the reciprocal of w is exactly 9. In other words, 1/w can only be equal to 9 and not less than or greater than 9.Here's how to express each statement as an inequality in terms of 8a^2:
1/w ≤ 9:
Multiplying both sides by w, we get:1 ≤ 9w
Subtracting 1 from both sides, we get:0 ≤ 9w - 1
Multiplying both sides by 8a^2, we get:0 ≤ 72a^2w - 8a^2
Therefore, the inequality for 1/w ≤ 9 in terms of 8a^2 is:0 ≤ 72a^2w - 8a^2
Note that the inequality for 1/w ≤ 9 involves a quadratic term with respect to "w," whereas the inequality for p/q ≤ 6 only involves linear terms with respect to "p" and "q."

If the claim is true, in a sample of 43 wall clocks, what is the probability that the mean clock life would be less than 17.9 years? Round your answer to four decimal places.
There is a 0.9830, or 98.30%, probability that the mean clock life will exceed 12.5 years.
What is probability?Probability is a metric used to express the possibility or chance that a particular event will occur.
Probabilities can be expressed as fractions from 0 to 1, as well as percentages from 0% to 100%.
Probability is simply the possibility that something will happen. When we don't know how something will turn out, we can talk about the possibility of one outcome or the likelihood of several.
The study of events that fit into a probability distribution is known as statistics.
So, the likelihood that the average clock life would exceed 12.5 years:
This is the p-value of Z when X = 12.5 subtracted by 1.
So,
Z = X - μ/σ
Z = 12.5 - 14/.07071
Z = -2.12
Z = The pvalue for -2.12 is 0.0170.
1 - 0.0170 = 0.9830
The likelihood that the mean clock life will be longer than 12.5 years is 0.9830, or 98.30%.

The sketch of the graph of y = 1/f(x) is added as an attachment
Sketching the graph of y = 1/f(x)To find the function equation, we need to determine the factors of the equation based on the zeros of the function.
Since the zeros of the function are at x = -5, -1, and 4, the factors of the equation will be:
(x + 5), (x + 1), and (x - 4)
Multiplying these factors together gives us:
f(x) = a(x + 5)(x + 1)(x - 4)
To find the value of the constant term a, we can use the fact that the graph passes through the point (0, -4):
-4 = a(0 + 5)(0 + 1)(0 - 4)
-4 = -20a
So, we have
a = 1/5
Therefore, the function equation is:
f(x) = 1/5(x + 5)(x + 1)(x - 4)
For the graph of y = 1/f(x), we have
y = 5/[(x + 5)(x + 1)(x - 4)]

I really need help with this two please help to find x value and explain with reasons
In the first triangle, the angle x = 45°
In the second triangle, the angle y = 75°
In the second triangle, the angle x = 45°
How to find the angles in the triangles?To find the angles in the triangles, we proceed as folows.
a. In the first triangle, let the base angle to the left be p. We know that we have a parallelogram there.
Now, in the parallelogram,
102° + p = 180°sum of (interior angles of a parallelogram)
So, p = 180° - 102°
= 78°
Now, in the larger triangle,
x + p + 57° = 180° (sum of angles in a triangle)
Since p = 78°, we have that
x + 78° + 57° = 180°
x + 135° = 180°
x = 180° - 135°
= 45°
So, x = 45°
b. In figure 2, we have two isoceles triangles.
i. In the first triangle, both base angles are y.
So, y + y + 30° = 180° (sum of angles in atriangle)
2y + 30° = 180°
2y = 180° - 30°
2y = 150°
y = 150°/2
y = 75°
So, y = 75°
ii. In the second triangle also, both base angles are x and the other angle is a right angle which is 90°.
So, x + x + 90° = 180° (sum of angles in a triangle)
2x + 90° = 180°
2x = 180° - 90°
2x = 90°
x = 90°/2
x = 45°
So, x = 45°

A particle moving in the horizontal direction has its position given by x(t). Find the expression for the velocity.
Ignore the pencil writing and red pen, just answer the printed answer.
The expression for the velocity is v(t) = 30m/s
Expression for the Velocity calculation(a) x(t) = 30t
The velocity is the derivative of the position function with respect to time:
v(t) = dx/dt
Since x(t) = 30t, we have:
v(t) = d/dt (30t)
= 30
So the expression for velocity is v(t) = 30 m/s.
(b) x(t) = 7sin(30)
The velocity is the derivative of the position function with respect to time:
v(t) = dx/dt
Since x(t) = 7sin(30), we have:
v(t) = d/dt (7sin(30))
= 7cos(30) * d/dt (30t)
= 3.5cos(30)
So the expression for velocity is v(t) = 3.5cos(30) m/s.
(c) x(t) = ecos(701)
The velocity is the derivative of the position function with respect to time:
v(t) = dx/dt
Since x(t) = ecos(701), we have:
v(t) = d/dt (ecos(701))
= -e sin(701) * d/dt (701t)
= -701e sin(701t)
So the expression for velocity is v(t) = -701e sin(701t) m/s.

The solution set of f(x) > 0 is x ∈ (-2, 8).
What is the set of the function?
To find the solution set of f(x) > 0, we need to first determine the critical values of x where f(x) changes sign.
Let's start by finding the domain of the function:
x² - 6x - 16 ≠ 0
We can solve for x by using the quadratic formula:
x = [6 ± √(6² + 4(16))]/2 = [6 ± √52]/2 = 3 ± √13
So the domain of f(x) is (-∞, 3 - √13) U (3 + √13, ∞).
Now let's factor the numerator and denominator of f(x):
f(x) = (x + 10)/[(x - 8)(x + 2)]
The critical points occur where the numerator or denominator of f(x) changes sign.
The numerator changes sign at x = -10, and the denominator changes sign at x = -2 and x = 8.

Give your answer to two decimal places.
Therefore, a sharpening costs Dollar 1.85.
what is dollarThe US, Canada, Australia, and some nations in the Pacific, Caribbean, Southeast Asia, Africa, and South America all use the dollar as their primary unit of exchange. The word "$" is used to denote it.
Let's use $a for the sharpener's price. We can state that the price of a book is $a + 1.95 because it costs $1.95 more than a sharpening.
We are aware of the $26.10 total cost of 10 sharpeners and 2 books. This can be expressed as an equation:
10a + 2(a + 1.95) = 26.10
If we simplify this equation, we get:
12a + 3.90 = 26.10
3.90 less from each side results in:
12a = 22.20
By multiplying both sides by 12, you get:

A popular beach currently has 88 visitors, and 28 of them are sunbathing. What is the probability that a randomly chosen beachgoer is sunbathing? Write your answer as a fraction or whole number.
The probability that the randomly selected person is taking a sunbath is 7/22.
Science uses a figure called the probability of occurrence to quantify how likely an event is to occur.
It is written as a number between 0 and 1, or between 0% and 100% when represented as a percentage.
The possibility of an event occurring increases as it gets higher.
So, the probability formula is:
P(E) = Favourable events/Total events
Now, insert values in the formula as follows:
P(E) = Favourable events/Total events
P(E) = 28/88
P(E) = 14/44
P(E) = 7/22
Therefore, the probability that the randomly selected person is taking a sunbath is 7/22.
