Answer : No, levi's reasoning is incorrect. The correct answer is, [tex]2.63\times 10^{11}[/tex]
Step-by-step explanation :
Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power. The numerical digit lies between 0.1.... to 9.9.....
For example :
5000 is written as [tex]5.0\times 10^3[/tex]
889.9 is written as [tex]8.899\times 10^{-2}[/tex]
In this examples, 5000 and 889.9 are written in the standard notation and [tex]5.0\times 10^3[/tex] and [tex]8.899\times 10^{-2}[/tex] are written in the scientific notation.
If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.
As we are given the 263,000,700,000 in standard notation.
Now converting this into scientific notation, we get:
[tex]\Rightarrow 263,000,700,000=2.63\times 10^{11}[/tex]
As, the decimal point is shifting to left side, thus the power of 10 is positive.
Hence, the correct answer is, [tex]2.63\times 10^{11}[/tex]
Answer:
No. He answered incorrectly. The correct scientific notation of the number will be [tex]2.630007\times10^{11}[/tex].
Step-by-step explanation:
Levi wants to write 263,000,700,000 in the scientific notation.
In scientific notation, the number is represented by a numerical value between 1 and 9.99...., multiplied by power of 10.
The given number can be written as,
[tex]263,000,700,000=2.630007\times100,000,000,000\\263,000,700,000=2.630007\times10^{11}[/tex]
Thus, in scientific notation, the given number can be written as [tex]2.630007\times10^{11}[/tex].
Here, the numerical value is 2.630007 and power of 10 is [tex]10^{11}[/tex].
Now, the power of 10 is 11 which is positive. So, Levi has answered incorrectly.

For the following graph, what type of discontinuity occurs at x = 6 and what step of continuity is broken?
A) infinite and f(6) does not exist.
B) removable and f(6) does not exist.
C) jump and limx→6− f(x) ≠ limx→6+ f(x).
D) infinite and limx→6− f(x) ≠ limx→6+ f(x).
Answer:
A) Infinite and f(6) does not exist
Step-by-step explanation:
The three types of discontinuities are:
1. Removable or Hole: When the left hand limit is same as right hand limit but they are not equal to the value of function at x = 6.
Graphically if there exist a hole at the point x = 6, removable discontinuity occurs. But, it is not the case in the given graph.
2. Jump: When the left hand limit is not same as right hand limit.
But graphically, we see that both left and right limit at x=6 are tending to infinity i.e. both limits are same.
3. Infinite: It occurs when there exists vertical or horizontal asymptotes between the function and both limits tend to infinity.
Graphically, we see that the function has infinite discontinuity as there exist vertical asymptote and the value of function does not exist at x = 6.

The distance between the cities Chicago and Toronto is 540 miles. A motorcycle's speed is 48 mph. For a car, it takes 2.25 hours less to cover the same distance than for the motorcycle. How long does it take them to meet, if they start moving towards each other simultaneously?
The answer is in hours.
PLEASE HELP ME
Answer:
5 hours
Step-by-step explanation:
given :
Distance between the cities = 540 miles
Speed of motorcycle =48 mph
TO CALCULATE THE TIME TAKEN BY MOTORCYCLE TO COVER THE TOTAL DISTANCE WE USE THE FORMULA :
[tex]\frac{DISTANCE}{SPEED}[/tex]
By putting given values in the formula we get :
[tex]\frac{540}{48}[/tex]
= 11.25 hours
Now, We are given that for a car to cover the same distance it takes 2.25 hours less than the time taken by motorcycle
⇒ 11.25 hours - 2.25 hours
⇒ 9 hours
Thus , Time taken by car to cover the same distance is 9 hours .
Now to calculate speed of car by using formula:
[tex]\frac{distance}{time}[/tex]
[tex]\frac{540}{9}[/tex]
= 60 mph
Let t be the time taken to meet if they start moving towards each other.
So distance covered by motorcycle in t hours is
speed\times time
= 48t miles
Distance covered by car in t hours is
speed\times time
= 60t miles
⇒ 60t + 48t =540
⇒ 108t = 540
⇒ t= 5 hours
Therefore, time taken to meet if they start moving towards each other is 5 hours.
what is equation of the perpendicular bisector of the line segment between ( -3,4)and(5,6)
Answer:
Hey There so i saw your question. Solving it is very easy so i'm gonna help you step by step.
Step-by-step explanation:
(-3,4) (5,6) the slope formula y2-y1 over x2-x1
so its 6-4/5-(-3) which you gonna get 2/8 which is 1/4 so thats your slope.
*just know that your slope will flip since it's perpendicular and not parallel
so now you gonna find "b" on the equation Y=mx=b so out of your 2 points, choose one. I choose (5,6) all you gotta do is plug it into y=mx+b
so it's gonna be 6= 4 (the flipped slope)*5+b {1.4*5 = 1.25}
so you gonna take 6 - 20 = -14 whcih is your b
so your new equation + the answer is Y= 4x-14
The car at each vertex of a Ferris wheel holds a maximum of 5 people. The sum of the measures of the angles of the Ferris wheel is 7740º. What is the maximum number of people that the Ferris wheel can hold?
225
300
250
200
Answer:
225
Step-by-step explanation:
The sum total of all the angles is 7,740 degrees,
The formula for the interior angle is 180(n - 2) where n is the number of sides in the polygon
Set this equal to 7740
180 (n-2) = 7740
Divide each side by 180
180/180 (n-2) = 7740/180
n-2 =43
Add 2 to each side
n-2+2 = 43+2
n = 45
Each vertex hold 5 people so take n and multiply by 5
45*5 = 225
The Ferris wheel holds 225 people

Stefan sells jin a bicycle for $114 and a helmet for $18. The toltal cost for jin is 120% of what stefan spent originally to buy the bike and helmet. How much did stefan spend originally? How much money did he make by selling the bicycle and helmet to jin?
Answer:
Stefan spend originally $110 and the money stefan make by selling the bicycle and helmet to jin is $22 .
Step-by-step explanation:
As given
Stefan sells jin a bicycle for $114 and a helmet for $18.
Total cost of the bicycle and helmet = $114 + $18
= $132
The total cost for jin is 120% of what stefan spent originally to buy the bike and helmet.
120% is written in the decimal form.
[tex]= \frac{120}{100}[/tex]
= 1.20
Let us assume that the Stefan spend originally for bike and helmets be x.
Than the equation becomes
1.20 × x = 132
1.20x = 132
[tex]x = \frac{132}{1.20}[/tex]
x = $110
Therefore stefan spend originally be $110 .
Now find out how much money did he make by selling the bicycle and helmet to jin .
Money make by Stefan = Total selling cost of helmet and bicycle - Total amount of stefan spends for purchasing.
Money make by Stefan = 132 - 110
Money make by Stefan = $22
Therefore the money stefan make by selling the bicycle and helmet to jin is $22 .
Stefan's original expenditure for the bicycle and helmet was $110. He made a profit of $22 by selling these items to Jin.
Explanation:Stefan sold the bicycle and helmet to Jin for a total of $132 ($114 + $18). We know that this amount represents 120% of what Stefan originally spent. To determine Stefan's original expenditure, we'll therefore divide the total amount he earned by 120 and then multiply by 100 (as the cost is 100% for him). So, Stefan's original expenditure would be (132/120)*100 = $110.
Now, to determine Stefan's profit, we subtract his original expenditure from the amount for which he sold the items to Jin. That is, $132 - $110 = $22. So, Stefan made a $22 profit from selling the bicycle and helmet.

The order of several matrices are given. A = 3x2 B = 3x5 C = 2x3 D = 5x7 E = 3x5 Which can be multiplied?
Answer:
A/C and B/D and C/E
Step-by-step explanation:
given the order of 2 matrices
(m × n)(p × q)
For the matrices to be conformable for multiplication
The number of columns in the first must equal the number of rows in the second
That is n = p and the resulting product has order m × q
From the order of matrices given
A and C, B and D, C and E can be multiplied
The matrices that can be multiplied are A*C, C*A, B*D, and E*D, as the number of columns in the first matrix equals the number of rows in the second.
Explanation:In matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix. Therefore, given the order of the matrices A = 3x2, B = 3x5, C = 2x3, D = 5x7, and E = 3x5, the possible matrix multiplications are: A*C, C*A, B*D, and E*D. For instance, you can multiply A (which is 3x2) with C (which is 2x3) because the number of columns in matrix A is equal to the number of rows in matrix C.

Write the equation of a line that passes through the point (-1,5) and has a slope of -7. Your answer should be given in the form y = mx + b.
The equation of the line that passes through the point (-1,5) and has a slope of -7 is y = -7x - 2. This can be determined by substituting the given values into the equation y = mx + b and solving for 'b'.
Explanation:In mathematics, the equation of a line is commonly represented as y = mx + b, where 'm' represents the slope and 'b' is the y-intercept. In this equation, the slope '-7' is the rate at which 'y' changes for a unit change in 'x'. The y-intercept is the 'y' value when 'x' is zero.
It's given that the line passes through the point (-1,5). We can substitute these values into the equation to find 'b':
5 = -7(-1) + b, which simplifies to 5 = 7 + b. Therefore, 'b' equals to -2 after rearranging.
So, the equation of the line that passes through the point (-1,5) and has a slope of -7 is y = -7x - 2.

Monica has a bag of marbles. There are 4 red marbles and 7 blue marbles and 5 yellow marbles in a bag. Monica will randomly pick two marbles out of the bag replacing the first marble before picking the second marble. What is the probability of Monica picking a red and then blue marble?
Answer:
[tex]\frac{7}{64}\approx 0.11[/tex]
Step-by-step explanation:
We have been given that there are 4 red marbles and 7 blue marbles and 5 yellow marbles in a bag. Monica will randomly pick two marbles out of the bag replacing the first marble before picking the second marble.
Since Monica will replace the first marble before picking the second marble, therefore, probability of both events will be independent and probability of occurring one event will not affect the probability of second event's occurring.
Since the probability of two independent compound events is always the product of probabilities of both events.
[tex]P(\text{A and B})=P(A)*P(B)[/tex]
Now let us find probability of picking a red marble out of 16 (4+7+5) marbles.
[tex]P(Red)=\frac{\text{Total red marbles}}{\text{Total marbles}}[/tex]
[tex]P(Red)=\frac{4}{16}[/tex]
Probability of picking blue ball out of 16 (4+7+5) marbles:
[tex]P(Blue)=\frac{\text{Total blue marbles}}{\text{Total marbles}}[/tex]
[tex]P(Blue)=\frac{7}{16}[/tex]
Now let us find probability of Monica picking a red and then a blue marble.
[tex]P(\text{Red and Blue})=\frac{4}{16}\times \frac{7}{16}[/tex]
[tex]P(\text{Red and Blue})=\frac{1}{4}\times \frac{7}{16}[/tex]
[tex]P(\text{Red and Blue})=\frac{7}{4*16}[/tex]
[tex]P(\text{Red and Blue})=\frac{7}{64}[/tex]

Problem Two: B
Step-by-step explanation:
Problem One
A and B are both wrong for the same reason. The graph for both of them will increase. Any time you raise a base greater than 1 to a power, the graph goes up. See below. The red graph is y = 12*1.1^2
The question is giving you a big hint by showing you which point to look at. When x = 1, y = 8. What will do that?
Is it 12 * 1/2 or is it 12 * 2/3
I think you will find it is 12*2/3 So the answer is D
Part B
This one is just the opposite, only now you have to figure out which graph you are getting. A is the only one that is obviously wrong. When x = 1, A will give
40* 1.5 which is 60 which is not enough.
C is too large. 40 * 3.25 = 130 so that does not describe the graph when x = 1.
So B and D are your only choices. D is still a little too big. See if you can get D to be 100 when D = 1
That leaves you with b
y = 40 * 2.25 = 90 which is just what you want.
How are vectors used in real life?
Answer:
Vectors can be used in sports to define how a baseball player moves to catch a high fly baseball they can also be used with aircrafts.
Remember that science uses vectors to describe anything that has both a direction and a magnitude (size or quantity). These are drawn as pointed arrows, which length represents the magnitude. They are very used to locate persons or objects as the final direction can be predicted using a reference point, an stimated speed and direction. Vectors are also usefull to predict what would happen if two objects come into contact, an example would be predicting the movement of billiard balls, or calculating the trajectory of a golf ball.
