f(x)= a(x+p)² +q and g(x)= 0 3 3.1 x + p 1. The turning point of f is (1;4) and the asymptotes of g intersect at the turning point of f. Both graphs cut the y-axic at 3. 3.2 3.3 3.4 a 10 g +94 (1:4) Determine the equation of f Determine the equation of g Determine the coordinates of the x-intercept of g For which values of x will f(x) ≥ g(x)? [9]
Step-by-step explanation:
Let's solve the given questions step by step:
1. Determine the equation of f:
From the given information, we know that the turning point of f is (1, 4). The general form of a quadratic function is f(x) = ax^2 + bx + c. We are given that f(x) = a(x + p)^2 + q, so let's substitute the values:
f(x) = a(x + p)^2 + q
Since the turning point is (1, 4), we can substitute x = 1 and f(x) = 4 into the equation:
4 = a(1 + p)^2 + q
This gives us one equation involving a, p, and q.
2. Determine the equation of g:
The equation of g is given as g(x) = 0.3x + p1.
3. Determine the coordinates of the x-intercept of g:
The x-intercept is the point where the graph of g intersects the x-axis. At this point, the y-coordinate is 0.
Setting g(x) = 0, we can solve for x:
0 = 0.3x + p1
-0.3x = p1
x = -p1/0.3
Therefore, the x-intercept of g is (-p1/0.3, 0).
4. For which values of x will f(x) ≥ g(x)?
To determine the values of x where f(x) is greater than or equal to g(x), we need to compare their expressions.
f(x) = a(x + p)^2 + q
g(x) = 0.3x + p1
We need to find the values of x for which f(x) ≥ g(x):
a(x + p)^2 + q ≥ 0.3x + p1
Simplifying the equation will involve expanding the square and rearranging terms, but since the equation involves variables a, p, and q, we cannot determine the exact values without further information or constraints.
To summarize:
We have determined the equation of f in terms of a, p, and q, and the equation of g in terms of p1. We have also found the coordinates of the x-intercept of g. However, without additional information or constraints, we cannot determine the exact values of a, p, q, or p1, or the values of x for which f(x) ≥ g(x).

the radius of curve r= 20m
velocity v= 15 m/s
Substituting we have
\(F_c = \frac{0.3*15^2}{20}\\\\F_c= \frac{0.3*225}{20}\\\\ F_c=\frac{67.5}{20}\\\\F_c=3.37N\)
The force is 3.37N
TV advertising agencies face increasing challenges in reaching audience members because viewing TV programs via digital streaming is gaining in popularity. A poll reported that 54% of 2348 American adults surveyed said they have watched digitally streamed TV programming on some type of device.
1) Calculate and interpret a confidence interval at the 99% confidence level for the proportion of all adult Americans who watched streamed programming up to that point in time.
A) We are 99% confident that this interval does not contain the true population proportion.
B) We are 99% confident that this interval contains the true population proportion.
C) We are 99% confident that the true population proportion lies below this interval.
D) We are 99% confident that the true population proportion lies above this interval.
2) What sample size would be required for the width of a 99% CI to be at most 0.03 irrespective of the value of p?
Answer:
1
Option B is the correct answer
2
\(n = 9418\)
Step-by-step explanation:
From the question we are told that
The sample size is \(n = 2348\)
The sample proportion is \(\r p = 0.54\)
Given that the confidence level is 99% then the level of significance is evaluated as
\(\alpha = 100 - 99\)
\(\alpha = 1\)%
\(\alpha = 0.01\)
Next we obtain the critical values of \(\frac{\alpha }{2}\) from the normal distribution table. The values obtained is
\(Z_{\frac{\alpha }{2} } = 2.58\)
The reason we are obtaining values for is because is the area under the normal distribution curve for both the left and right tail where the 99% interval did not cover while is the area under the normal distribution curve for just one tail and we need the value for one tail in order to calculate the confidence interval .
Next is to calculate the margin of error which is mathematically evaluated as
\(MOE = Z_{\frac{\alpha }{2} } * \sqrt{ \frac{\r p ( 1 - \r p )}{n } }\)
substituting values
\(MOE = 2.58 * \sqrt{ \frac{0 .54( 1 - 0.54 )}{2348 } }\)
\(MOE = 0.0265\)
Now the interval for the 99% confidence level is evaluated as
\(\r p - MOE < \r p < \r p + MOE\)
substituting values
\(0.514 < \r p <0.567\)
Looking at the Confidence interval we see that the proportion of Americans that watched streamed program up to that point in time is between
51.4% and 56.7%
Hence we are 99% confident that this interval contains the true population proportion.
The sample size that will be required for the width o 99% Cl is mathematically evaluated as
\(n = \frac{4 *[Z_{\frac{\alpha }{2} }]^2 * \r p (1- \r p )}{MOE^2}\)
substituting values
\(n = \frac{4 *2.58^2 * 0.54 (1- 0.54 )}{0.0265^2}\)
\(n = 9418\)

3x - y = 1; D: (-3, -1, 0, 4)
Graph each function for the given domain
Evaluating the function in the values of the domain we will get some coordinate pairs. The graph of these is in the image at the end.
How to graph the function in the given domain?Here we have the function:
3x - y = 1
And we want to graph this in the domain (-3, -1, 0, 4)
To do so, we need to evaluate the function (the values of x) in the values of the domain.
Solving the equation for y we get:
y = 3x - 1
Now, when x = -3
y = 3*-3 - 1 = -10
when x = -1
y = 3*-1 - 1 = -4
when x = 0
y = 3*0 - 1 = -1
When x = 4
y = 3*4 - 1 = 11
So we have the points (-3, -10), (-1, -4), (0, -1), (4, 11)

What is the slope of the line that represents this relationship?
Graph the line that represents this relationship.
The line parallel to the x-axis passing through the points (5,5) and (-5,5) has a slope of 0, indicating a horizontal line with a constant y-coordinate value of 5.
To determine the slope of the line that represents this relationship, we can use the formula for slope, which is given by:
slope = (change in y-coordinates) / (change in x-coordinates)
In this case, we are given two points on the line: (5,5) and (-5,5).
The change in y-coordinates is 5 - 5 = 0, as the y-coordinate remains constant.
The change in x-coordinates is -5 - 5 = -10.
Substituting these values into the slope formula, we get:
slope = 0 / -10 = 0
Therefore, the slope of the line that represents this relationship is 0.
A slope of 0 indicates that the line is parallel to the x-axis. This means that the line has a constant y-coordinate value for all x-coordinate values. In this case, the line passes through the point (5,5) and (-5,5), and it remains at y = 5 for all x-values.
Visually, a line with a slope of 0 would be a horizontal line on the coordinate plane. It does not have an upward or downward slope but remains parallel to the x-axis.
It's important to note that the slope of 0 indicates a relationship where the dependent variable (y) does not change with respect to the independent variable (x). In this case, no matter the value of x, the corresponding y-value remains constant at 5.

AB and AD are tangent to circle C. Find the length of AB, if AB = 8x and AD = x + 9. Round your answer to 2 decimal places.
Answer:
To find the length of AB, we can use the property that two tangents to a circle from the same external point are equal. This means that AB = AD. Substituting the given values, we get:
8x = x + 9
Solving for x, we get:
x = 1.5
Therefore, AB = 8x = 8(1.5) = 12.
To check our answer, we can use the Pythagorean theorem on triangle ABD, since AB is perpendicular to BD at the point of tangency. We have:
AB^2 + BD^2 = AD^2
Substituting the values, we get:
12^2 + BD^2 = (1.5 + 9)^2
Simplifying, we get:
BD^2 = 56.25
Taking the square root of both sides, we get:
BD = 7.5
Hence, the length of AB is 12 and the length of BD is 7.5.

An article reports that when each football helmet in a random sample of 34 suspension-type helmets was subjected to a certain impact test, 24 showed damage. Let p denote the proportion of all helmets of this type that would show damage tested in the prescribed manner.
Required:
a. Calculate a 99% Cl for p.
b. What sample size would be required for the width of a 99% Cl to beat most .10, irrespective of p ?
Answer:
a
\(0.5043 < p <0.9075\)
b
\(n = 24\)
Step-by-step explanation:
From the question we are told that
The sample size is n = 34
The number of damaged helmets is x = 24
Now the proportion of damaged helmets is mathematically represented as
\(\r p = \frac{k}{n }\)
substituting values
\(\r p = \frac{24}{34 }\)
\(\r p = 0.7059\)
Given that the confidence level is 99% the level of significance can be evaluated as
\(\alpha = 100 - 99\)
\(\alpha = 1\)%
\(\alpha = 0.01\)
Next we obtain the critical value of \(\frac{\alpha }{2}\) from the normal distribution table, the value is \(Z_{\frac{\alpha }{2} } = 2.58\)
The reason we are obtaining critical values of \(\frac{\alpha }{2}\) instead of \(\alpha\) is because
\(\alpha\) represents the area under the normal curve where the confidence level interval ( \(1-\alpha\)) did not cover which include both the left and right tail while
\(\frac{\alpha }{2}\)is just the area of one tail which what we required to calculate the margin of error
The margin of error is mathematically represented as
\(MOE = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\r p ( 1 - \r p)}{n} }\)
substituting values
\(MOE = 2.58 * \sqrt{\frac{ 0.7059 ( 1 - 0.7059)}{34} }\)
\(MOE =0.2016\)
The 99% confidence interval for p is mathematically represented as
\(p-MOE < p < p + MOE\)
substituting values
\(0.7059 - 0.2016 < p <0.7059 + 0.2016\)
\(0.5043 < p <0.9075\)
The sample size required for the width of a 99% Cl to beat most 0.10, irrespective of p ? is mathematically represented as
\(n \ge \frac{ Z_{\frac{\alpha }{2} } * \sqrt{\r p (1- \r p )} }{\frac{\sigma }{2} }\)
Here \(\sigma = 0.10\) telling us that the deviation from the sample proportion is set to 0.10 irrespective of the value of \(\r p\)
so the sample size for this condition is
\(n \ge \frac{ 2.58 * \sqrt{ 0.7059 (1- 0.7059)} }{\frac{0.10 }{2} }\)
\(n \ge 23.51\)
=> \(n = 24\)
10. Prime numbers from 1 to 100 are running a restaurant - PRIME SPOT, near a tourist point. On a winter holiday, 1 and the composite numbers up to 100 enter the restaurant for dinner after their picnic at the same point. The dining hall has tables with seating capacity 15 for each. If they occupy tables without leaving any chair free, how many tables are required? If each prime number attender has to serve equal number of customers, how many customers should each one get to serve?
6 tables are required. Each prime number attender should serve 3 customers each.
The prime numbers between 1 and 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
All the numbers other than prime numbers are composite numbers.
The composite numbers from 1 to 100 are: 1, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.
Now, as there are 25 primes and 75 composites in the group that visited the restaurant, we can calculate the number of tables required by dividing the number of people by the seating capacity of each table.
Each table has a seating capacity of 15, so the number of tables required will be: Number of tables = (Number of customers)/(Seating capacity of each table)Number of customers = 25 (the number of primes) + 75 (the number of composites) = 100Number of tables = 100/15 = 6 tables
Therefore, 6 tables are required.
Now, as each prime number attender has to serve an equal number of customers, we need to calculate how many customers each one should serve.
Each prime attender has to serve 75/25 = 3 customers each, as there are 75 composites and 25 primes.
Thus, each prime number attender should serve 3 customers each.

Two sets that contain exactly the same elements are called ___ sets.
Two sets that contain exactly the same elements are called "equal sets" or "identical sets."
In set theory, the concept of equality between sets is defined by the axiom of extensionality, which states that two sets are equal if and only if they have the same elements.
To illustrate this concept, let's consider two sets: Set A and Set B. If every element of Set A is also an element of Set B, and vice versa, then we say that Set A and Set B are equal sets. In other words, the sets have the exact same elements, regardless of their order or repetition.
For example, if Set A = {1, 2, 3} and Set B = {3, 2, 1}, we can observe that both sets contain the same elements, even though the order of the elements is different. Therefore, Set A is equal to Set B.
In summary, equal sets refer to two sets that possess exactly the same elements, without considering the order or repetition of the elements. The concept of equality is fundamental in set theory and forms the basis for various operations and theorems in mathematics.
