A particle moves along the x-axis with the given acceleration function a(t) = 8t - 6, initial position s(0) = 2, and initial velocity v(0). Find the position function.
Answer:
[tex]s(t) = \frac{4t^3}{3} - 3t^2 + v(0)t + 2[/tex]
Step-by-step explanation:
Relation between acceleration, velocity and position:
The velocity function is the integral of the acceleration function.
The position function is the integral of the velocity function.
Acceleration:
As given by the problem, the acceleration function is:
[tex]a(t) = 8t - 6[/tex]
Velocity:
[tex]v(t) = \int a(t) dt = \int (8t - 6) dt = \frac{8t^2}{2} - 6t + K = 4t^2 - 6t + K[/tex]
In which the constant of integration K is the initial velocity, which is v(0). So
[tex]v(t) = 4t^2 - 6t + v(0)[/tex]
Position:
[tex]s(t) = \int v(t) dt = \int (4t^2 - 6t + v(0)) dt = \frac{4t^3}{3} - \frac{6t^2}{2} + v(0)t + K = \frac{4t^3}{3} - 3t^2 + v(0)t + K[/tex]
The initial position is s(0) = 2. So
[tex]s(t) = \frac{4t^3}{3} - 3t^2 + v(0)t + 2[/tex]

c. 6 to 5
d. 9 to 8
Please select the best answer from choices provided
Answer:
B. 3 to 2
Step-by-step explanation:
I calculated it logically
The ratio of the frequency of G to C is 1.5. So, option b is correct.
What is meant by frequency ?Frequency of a wave is defined as the number of oscillations completed by the wave in one second.
Here,
The frequency of note G, f(G) = 392 Hz
The frequency of note C, f(C) = 262 Hz
The ratio of the frequency of G to C, r = frequency of G/frequency of C
r = f(G)/f(C)
r = 392/262
r = 1.496 approximately r = 1.5
Hence,
The ratio of the frequency of G to C is 1.5

A consulting firm submitted a bid for a large research project. The firm's management initially felt they had a chance of getting the project. However, the agency to which the bid was submitted subsequently requested additional information on the bid. Past experience indicates that for of the successful bids and of the unsuccessful bids the agency requested additional information. a. What is the prior probability of the bid being successful (that is, prior to the request for additional information) (to decimal)? b. What is the conditional probability of a request for additional information given that the bid will ultimately be successful (to decimals)? c. Compute the posterior probability that the bid will be successful given a request for additional information (to decimals).
Answer:
Step-by-step explanation:
Dear student, the missing data in the given information includes that:
The past experience showcases that for 75% successful bids & 40% unsuccessful bids, additional information is being requested by the agency.
∴
For a bid to be successful, the chance is half
Thus, the prior probability P(successful) is;
P(successful) = [tex]\dfrac{50}{50+50}[/tex]
P(successful) = 0.5
The conditional probability is:
[tex]P(request/successful)= \dfrac{P(request \& \ successful) }{P(successful)}[/tex]
[tex]P(request/successful)= 0.75[/tex]
To compute the posterity probability, we use the Naive Bayes Theorem:
So,
Let S = successful, Us = Unsuccessful; R = request:
Then;
[tex]P(S/R) = \dfrac{P(R/S) *P(S)}{[P(R/s)* P(S) +P(R/Us) *P(Us)]}[/tex]
[tex]P(S/R) = \dfrac{0.75*0.5}{0.75* 0.5 +0.40 *0.5]}[/tex]
[tex]P(S/R) = \dfrac{0.375}{0.375 +0.20} \\ \\ P(S/R) = \dfrac{0.375}{0.575}[/tex]
P(S/R) = 0.65

Answer:
[tex]x=37.4[/tex]
Step-by-step explanation:
In an right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse (a/h).
Therefore, we have the following equation:
[tex]\cos 68^{\circ}=\frac{14}{x},\\x=\frac{14}{\cos 68^{\circ}}\approx\boxed{37.4}[/tex]
Find the measure of the exterior angle.
Answer:
u = 143º
Step-by-step explanation:
Sum of angles in a triangle is 180
The unknown angle IN the triangle
x + 90 + 53 = 180
x + 143 = 180
x = 37º
x and u are supplementary angle which total 180
u + 37 = 180
u = 143º
Tiya earns $7 an hour mowing her neighbor's lawn.
Part A: Create two variables and determine which is dependent and which is independent for this situation. (4 points)
Part B: List three ordered pairs to show the values of the two variables. (3 points)
Part C: Write an equation to represent the relationship between the two variables. (3 points)
Part A) The independent variable is the hours that Tiya mows her neighbor's lawn, and we can denote that with x. It's the variable that isn't affected by other factors. The dependent variable is the amount of money Tiya earns, which we can denote with y. The dependent variable is the variable that is affected by other factors. The amount of money Tiya makes depends on how many hours she works.
Part B) As stated in part A, x is the hours and y is the money earned. The ordered pairs are in (x, y) form, with x being the hours and y being the money earned. For example, if Tiya worked one hour, x would be 1. As she earns 7 dollars per hour, she would earn 7 dollars (1*7), which is y. Therefore, one ordered pair could be (1, 7). Two hours would give Tiya 14 dollars, so we have another pair of (2, 14). Three hours would give Tiya 21 dollars, so we have (3, 21). We can do that for any numbers.
Part C) With every hour, Tiya earns 7 dollars. In order to find y, which is the amount of money totally earned, we multiply x by 7 (7 dollars per hour). Therefore, y = 7x.
The variables are:
x = number of hours that she worksy = how much she gets paid.And the proportional relation that relates them is:
y = $7*X
How to define variables?
The only information that we know is that Tiya earns $7 per hour, so the only variables that we can use are money and time.
The independent variable will be time, because she can decide how much time can she work. The dependent variable is money, because how much she earns depends on how many hours she works.
How to get ordered pairs?The ordered pairs are of the form (number of hours, money).
Some examples for this case are:
(0 hours, $0)(1 hour, $7)(2 hours, $14).How to get the equation?We define the variables.
x = number of hours that she worksy = how much she gets paid.Because she wins $7 per hour, the proportional equation will be:
y = $7*x

line f has a slope of -3. what is the slope of the line that is parallel to line f
Answer:
A line parallel has the same slope, so -3
The slope of the line that is parallel to line f is -3.
The given line f has a slope of -3.
We need to find the slope of the line that is parallel to line f.
What are parallel lines slope?The slope of parallel lines. The slope of parallel lines is equal. The parallel lines are equally inclined with the positive x-axis and hence the slope of parallel lines is equal.

A recent survey showed that 23.3 million adults have cut the cord on cable TV services, a 30% increase fron the previous year. If this trend continues, how many millions if adults can be expected to cut the cord next year?
Answer:
30,290,000 people
Step-by-step explanation:
The question is asking if the trend continues from the PREVIOUS year, so we would find the 30% of 23,300,000
23,300,000/100 = 233,000 = 1%
233,000 x 30 = 6,990,000
23,300,000 = 6,990,000 = 30,290,000
the auto parts department of an automotive dealership sends out a mean of 66 special orders daily. what is the probability that, for any day, the number of special orders sent out will be no more than 33
Answer:
0% probability that, for any day, the number of special orders sent out will be no more than 33
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 66 special orders daily
This means that [tex]\mu = 66[/tex]. We have the mean during a time interval, which means that the number of special orders follow a Poisson distribution, which has [tex]\sigma = \sqrt{\mu} = \sqrt{66}[/tex]
What is the probability that, for any day, the number of special orders sent out will be no more than 33?
Since the Poisson distribution, which is discrete, is approximated to the normal(which is continuous), we have to use continuity correction, and thus, this probability is P(X < 33 - 0.5) = P(X < 32.5), which is the p-value of Z when X = 32.5.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{32.5 - 66}{\sqrt{66}}[/tex]
[tex]Z = -4.12[/tex]
[tex]Z = -4.12[/tex] has a p-value of 0.
0% probability that, for any day, the number of special orders sent out will be no more than 33

Answer:
6
Step-by-step explanation:
The interquartile range is calculated by subtracting the first quartile from the third quartile. Box and whisker plots make it pretty easy to find the quartiles. The first quartile is the point where the box starts, and the third is where the box ends. The second is the median/line in the middle of the box.
So for that first box plot on the top, the first quartile is 7, because that's where the box begins. The third quartile is 22 because it's where the box ends.
For the second one, the first quartile is 8 and the third is 17.
To find the interquartile range of each, subtract the first quartile from the third. 22-7 = 15 and 17-8 = 9.
Now to find the difference in the interquartile ranges, subtract 9 from 15. You get 6, so that is the answer :)
In order to obtain a linear relationship between predictor and response variable, you had to transform the response variable (Y) using a natural log transformation. After running the regression your estimate of the slope is 0.30011. Because you transformed the response variable the slope is no longer the change in Y, measured in the original units, per unit change in the predictor X. Using a simple mathematical expression you can still interpret the slope. Following the expression used in the lecture, the correct interpretation is now that this is a ___________change in Y per unit change in X. And the value of this change is __________
Answer:
Estimated average
0.30011
Step-by-step explanation:
Estimate of slope = 0.30011
Given that the transformed response variable possess a slope that is no longer the change in Y
The correct interpretation is now that this is an estimated average change in Y per unit change in X. And the value of this change is 0.30011
