( velocity - on a graph )
Answer:
a) v_avg = k
b) 0.034 km/h
Step-by-step explanation:
a) The average velocity is given by the displacement over the time:
[tex]v_{avg}=\frac{\Delta x}{\Delta t}[/tex] (1)
Δx is the area under the line. In this case you can consider two areas. Firs, from t=0 t0 t=30 and from t=30 to t=50:
S1 = 30k
S2 = 20k/2 = 10k
Then, the total surface is:
S = S1+S2 = 50k
The average speed is:
v_avg = (50k)/(50s)= k
b) The value of k can be determined by using the expression for the total area under the line, which is the total displacement of the car S=1.7 km:
S=50k=1.7km
k=(1.7km)/(50k)=0.034km/h = 34 m/h
find an equation equivalent to r = 10 sin in rectangular coordinates
Answer:
x²+(y-5)²=25
Step-by-step explanation:
To convert polar into rectagular
[tex]->r=\sqrt{x^2+y^2} =>r^2=x^2+y^2\\[/tex]
also, y=rsin θ => sin θ=y/r
r= 10sinθ
r=[tex]\frac{10y}{r}[/tex] => r²=10y
therefore, x²+y²-10y=0
By completing the squares on y²-10y gives
x²+(y-5)²=25
which is the equation of the circle.
This is the Cartesian equation of a circle with center ( 0, 5)
and radius, r=5

6 more than a number is 36.
Answer:
30
Step-by-step explanation:
30+6= 36
36-6=30
Lets use n to represent the number.
6 more than a number: n + 6
is 36: = 36
Put the equation together:
n + 6 = 36
Solve for n.
n + 6 = 36
~Subtract 6 to both sides
n + 6 - 6 = 36 - 6
~Simplify
n = 30

Susan paid $240 to have her house decorated. The materials used to decorate the house coast $115, and service was charged at $5 an hour. How many hours was the house worked on?
Answer:
[tex] 240 =5x +115[/tex]
And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:
[tex] 240-115= 5x[/tex]
[tex] 125 = 5x[/tex]
And now we can divide both sides by 5 and we got:
[tex] x= 25[/tex]
So then the number of hours spent to decorate the house are 25
Step-by-step explanation:
Based on the information given we can model this function with this formula:
[tex] y = mx+b[/tex]
Where y represent the total cost paid, m the cost per hour representing the slope and x the number of hours worked and finally b the initial cost for the materials. Then our function is given by:
[tex] 240 =5x +115[/tex]
And we can solve for x in order to find the number hours using to decorate the house.
We can subtract in both sides 115 and we got:
[tex] 240-115= 5x[/tex]
[tex] 125 = 5x[/tex]
And now we can divide both sides by 5 and we got:
[tex] x= 25[/tex]
So then the number of hours spent to decorate the house are 25
The initial freshman class at a college is 10% smaller 1
than last year's class. But then during the first week of classes, 20 more
students enroll. If there were 950 students in last year's freshman class,
how many students are enrolled in this year's freshman class after the first
week of classes? *
Answer:
875 students are enrolled in this year's freshman class after the first week of classes.
Step-by-step explanation:
Last year, there were 950 students.
This year, the class is 10% smaller. So it's number of students is 100 - 10 = 90% of last year.
0.9*950 = 855
Initially, this year class had 855 students.
During the first week, 20 enrolled.
855 + 20 = 875.
So
875 students are enrolled in this year's freshman class after the first week of classes.
The Tennessean, an online newspaper located in Nashville, Tennessee, conducts a daily poll to obtain reader opinions on a variety of current issues. In a recent poll, 762 readers responded to the following question:
"If a constitutional amendment to ban a state income tax is placed on the ballot in Tennessee, would you want it to pass?" Possible responses were Yes, No, or Not Sure. Determine:
a. What was the sample size for this poll?
b. Are the data categorical or quantitative?
c. Would it make more sense to use averages or percentages as a summary of the data for this question?
d. Of the respondents, 67% said Yes, they would want it to pass. How many individuals provided this response?
Answer:
(a) The sample size for this poll is, n = 762.
(b) The data is categorical.
(c) It would make more sense to use percentages as a summary of the data for this question.
(d) Approximately 511 individuals provided the response "Yes".
Step-by-step explanation:
(a)
It is provided that in a recent poll, 762 readers responded to the following question:
"If a constitutional amendment to ban a state income tax is placed on the ballot in Tennessee, would you want it to pass?"
The possible responses were Yes, No, or Not Sure.
So, the sample size for this poll is, n = 762.
(b)
The outcomes of the poll are:
1: Yes
2: No
3: Not Sure
The data is categorical.
Categorical data can take labels such as, Gender (M/F), indicators (0/1) and so on.
(c)
Averages can be computed only for quantitative variable.
So, it would make more sense to use percentages as a summary of the data for this question.
That is, the percentage of people saying Yes, No and Not sure.
(d)
The percentage of people saying Yes is, 67%.
Compute the number of people saying Yes as follows:
[tex]n(\text{Yes})=P(\text{Yes})\times n[/tex]
[tex]=0.67\times 762\\=510.54\\\approx 511[/tex]
Thus, approximately 511 individuals provided the response "Yes".

what is the volume of a cone with a diameter of 30 feet and a hight of 60 feet
Answer:
4500[tex]\pi[/tex] [tex]ft^{3}[/tex]or 4712.39[tex]ft^{3}[/tex]
What we need to know: The formula for the volume of a cone is: [tex]V=\pi r^{2} \frac{h}{3}[/tex]
So we are solving for V
Step-by-step explanation:
1) Radius is half of diameter r=30/2 thus, your radius is 15
2) you then have all your variables so you can start plugging values into your equation:
r=15 h=60
[tex]V=\pi 15^{2} \frac{60}{3} \\V=\pi (225)*(20)\\V=\pi(4500) \\V= 4500\pi[/tex]
This would be your exact answer but if you are solving for a rounded answer it would be
V~4712.39[tex]ft^{3}[/tex]

The value of a certain car decreases by 16% each year. What is the 1⁄2-life of the car?
Answer:
The half life of the car is 3.98 years.
Step-by-step explanation:
The value of the car after t years is given by the following equation:
[tex]V(t) = V(0)(1-r)^{t}[/tex]
In which V(0) is the initial value and r is the constant decay rate, as a decimal.
The value of a certain car decreases by 16% each year.
This means that [tex]r = 0.16[/tex]
So
[tex]V(t) = V(0)(1-r)^{t}[/tex]
[tex]V(t) = V(0)(1-0.16)^{t}[/tex]
[tex]V(t) = V(0)(0.84)^{t}[/tex]
What is the 1⁄2-life of the car?
This is t for which V(t) = 0.5V(0). So
[tex]V(t) = V(0)(0.84)^{t}[/tex]
[tex]0.5V(0) = V(0)(0.84)^{t}[/tex]
[tex](0.84)^{t} = 0.5[/tex]
[tex]\log{(0.84)^{t}} = \log{0.5}[/tex]
[tex]t\log{0.84} = \log{0.5}[/tex]
[tex]t = \frac{\log{0.5}}{\log{0.84}}[/tex]
[tex]t = 3.98[/tex]
The half life of the car is 3.98 years.

Answer:
It is not equivalent
Step-by-step explanation:
Because the first expression simplified is 3x with the power of 9, and the first expression simplifies to x with a power of 9.
Answer:
No, they are not equivalent.
Step-by-step explanation:
In the case of the first expression: x³ * x³ * x³, you will solve the power first, before multiplying the whole numbers.
However, in terms of the second one, you are multiplying the powers first, and then solving for the power.
Take for example, x = 2. Plug in 2 for x in the expressions given:
x³ * x³ * x³ = 2³ * 2³ * 2³ = 8 * 8 * 8 = 64 * 6 = 512
However,
2^(3 * 3 * 3) = 2^(27) = 134,217,728

The coach of a college basketball team records the resting pulse rates of the team's players. A confidence interval for the mean resting pulse rate of all collegians based on these data is of little use because __________.
A) the sample size is small, so the margin of error will be large.
B) the members of the basketball team can't be considered a random sample from the entire collegiate population.
C) many of the students on the team may refuse to respond.
D) the coach has sampled the entire population so there is no need for inference.
Answer:
B) the members of the basketball team can't be considered a random sample from the entire collegiate population.
Step-by-step explanation:
The coach is trying to estimate a parameter of a population (the mean resting pulse rates of alla collegians) from a sample statistic (the mean resting pulse of the basketball team's players).
The confidence interval for the parameter is of little use as the sample of team players is not representative of the population of collegians. The sample can not be considered random. Then, the estimation of the parameter will be biased.
