what is the distance between -2,-3 and 3,3
Answer:
[tex]\sqrt{61}[/tex] (= 7.81 )
The distance between (-2,-3) and (3,3) is 7.81
Step-by-step explanation:
The distance between two points can be calculated using :
[tex]\sqrt{(X_{2}-X_{1})^{2} + (Y_{2}-Y_{1})^{2}}[/tex]
First point A = (-2,-3)
[tex]X_{1}[/tex] = -2
[tex]Y_{1}[/tex] = -3
Second Point B = (3,3)
[tex]X_{2}[/tex] = 3
[tex]Y_{2}[/tex] = 3
Insert the value of X and Y coordinates in the formula:
[tex]\sqrt{(X_{2}-X_{1})^{2} + (Y_{2}-Y_{1})^{2}}[/tex]
[tex]\sqrt{(3- (-2))^{2} + (3- (-3))^{2}}[/tex]
[tex]\sqrt{(3 + 2)^{2} + (3 + 3)^{2}}[/tex]
[tex]\sqrt{(5)^{2} + (6)^{2}}[/tex]
[tex]\sqrt{25 + 36}[/tex]
[tex]\sqrt{61}[/tex]
= 7.86
Distance between A and B is 7.81

Let f(x) be a continuous function such that f(1) = 3 and f '(x) = sqrt( x^3 + 4 ). What is the value of f(5)?
The value of f(5) is 49.1
Step-by-step explanation:
To find f(x) from f'(x) use the integration
f(x) = ∫ f'(x)
1. Find The integration of f'(x) with the constant term
2. Substitute x by 1 and f(x) by π to find the constant term
3. Write the differential function f(x) and substitute x by 5 to find f(5)
∵ f'(x) = + 6
- Change the root to fraction power
∵ =
∴ f'(x) = + 6
∴ f(x) = ∫ + 6
- In integration add the power by 1 and divide the coefficient by the
new power and insert x with the constant term
∴ f(x) = + 6x + c
- c is the constant of integration
∵
∴ f(x) = + 6x + c
- To find c substitute x by 1 and f(x) by π
∴ π = + 6(1) + c
∴ π = + 6 + c
∴ π = 6.4 + c
- Subtract 6.4 from both sides
∴ c = - 3.2584
∴ f(x) = + 6x - 3.2584
To find f(5) Substitute x by 5
∵ x = 5
∴ f(5) = + 6(5) - 3.2584
∴ f(5) = 49.1
If there is 1000$ in the lockbox what year will it be worth 64,000$ at 24% interest?
Hey there!
First, set up an exponential equation that represents the rate at which your original amount, 1000, gains interest:
y = 1000(1.24)^x
Y represents the value after X years. 1.24 represents the rate at which the money gains interest, 1 + 0.24 (your 24% interest rate in decimal form). 1000 is your original amount.
Now, set this equation equal to 64000, graph y = 64000 and y = 1000(1.24)^x on a graphing calculator, and see where the two equations intersect in order to solve for x.
They intersect when x is about 19.334, as seen in the graph below (it is very zoomed in so that you can see where the two functions intersect). Therefore, it will be about 19 years after the year in which you deposited the 1000 dollars before the money is worth 64000 dollars.

Amodel is made of a car. The car is 9 feet long and the model
is 6 inches long. What is the ratio of the length of the actual car
to the length of the model?
Answer:
18:1
Step-by-step explanation:
To convert inches to feet, we divide the value of inches by 12
Therefore, 6 inches=66/12=0.5 ft
The length of model = 0.5 ft
Length of actual car=9 ft
Ratio of actual car to model= 9:0.5=18:1
Therefore, the ratio is 18:1
The Undergraduate grade point average (UGPA) of students taking the Law School Admissions Test in recent year can be approximated with a normal distribution with mean=3.36 and standard deviation=.18
what is the minimum UGPA that will place a student in the top 10%?
Answer:
[tex]a=3.36 +0.816*0.18=3.507[/tex]
The value of height that separates the bottom 90% of data from the top 10% is 3.507.
Step-by-step explanation:
1) Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
2) Solution to the problem
Let X the random variable that represent the grades of a population, and for this case we know the distribution for X is given by:
[tex]X \sim N(3.36,0.18)[/tex]
Where [tex]\mu=3.36[/tex] and [tex]\sigma=0.18[/tex]
And the best way to solve this problem is using the normal standard distribution and the z score given by:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
For this part we want to find a value a, such that we satisfy this condition:
[tex]P(X>a)=0.10[/tex] (a)
[tex]P(X<a)=0.90[/tex] (b)
Both conditions are equivalent on this case. We can use the z score again in order to find the value a.
As we can see on the figure attached the z value that satisfy the condition with 0.90 of the area on the left and 0.10 of the area on the right it's z=0.816. On this case P(Z<0.816)=0.90 and P(Z>0.816)=0.1
If we use condition (b) from previous we have this:
[tex]P(X<a)=P(\frac{X-\mu}{\sigma}<\frac{a-\mu}{\sigma})=0.90[/tex]
[tex]P(z<\frac{a-\mu}{\sigma})=0.90[/tex]
But we know which value of z satisfy the previous equation so then we can do this:
[tex]z=0.816=\frac{a-3.36}{0.18}[/tex]
And if we solve for a we got
[tex]a=3.36 +0.816*0.18=3.507[/tex]
So the value of height that separates the bottom 90% of data from the top 10% is 3.507.
To find the minimum Undergraduate grade point average (UGPA) that would place a student in the top 10%, we use the Z-score corresponding to the top 10% (which is about 1.28) and apply it within the normal distribution parameters, mean (3.36) and standard deviation (.18). The result is a UGPA of approximately 3.59.
Explanation:This question pertains to the concept of normal distribution in statistics. Given a mean of 3.36 and a standard deviation of .18, we're asked to find the minimum Undergraduate grade point average (UGPA) that would place a student in the top 10%. This requires the understanding of Z-scores (standard deviations away from the mean).
The Z-score that corresponds to the top 10% in a standard normal distribution is about 1.28 (this value comes from a standard Z-table or can be calculated using a statistical calculator). Remember that the Z-score formula is Z = (X - μ) / σ, where X is the value we're looking for, μ is the mean, and σ is the standard deviation.
So, rearranging the formula to solve for X gives X = Z*σ + μ. Substituting the known values into the equation gives: X = (1.28*.18) + 3.36, which gives X approximately equal to 3.59. Therefore, the minimum UGPA that will place a student in the top 10% is approximately 3.59.

Thomas is starting a new company. He has two quotes from a computer company for the cost of computers and printers. If he buys three computers and one printer, the cost is $825. if he buys 4 computers and 2 printers, the cost is $1200. How much does each computer and printer cost?
Answer:
Cost of each Computer is $225 and Cost of each Printer is $150.
Step-by-step explanation:
Let the cost of the Computers be 'x'.
Let the cost of Printer be 'y'.
Given:
If he buys three computers and one printer, the cost is $825.
framing in equation form we get;
[tex]3x+y =825 \ \ \ \ \ equation\ 1[/tex]
Also Given:
if he buys 4 computers and 2 printers, the cost is $1200.
framing in equation form we get;
[tex]4x+2y =1200 \ \ \ \ \ equation\ 2[/tex]
Now Multiplying equation 1 by 2 we get;
[tex]2(3x+y)=825\times 2\\\\6x+2y=1650 \ \ \ \ \ equation\ 3[/tex]
Now Subtracting equation 2 from equation 3 we get;
[tex](6x+2y)- (4x+2y) = 1650-1200\\\\6x+2y-4x-2y = 450\\\\2x=450\\\\x=\frac{450}{2} =\$225[/tex]
Now Substituting the value of x in equation 1 we get;
[tex]3x+y=825\\\\3\times 225+y=825\\\\675+y =825\\\\y = 825 -675\\\\y = \$150[/tex]
Hence Cost of each Computer is $225 and Cost of each Printer is $150.
Answer:
Cost of each Computer is $225 and Cost of each Printer is $150.

CD has endpoints C(6,-8) and D(-4,10) on a coordinate plane. What are the coordinates of the midpoint CD
Final answer:
The midpoint of the line segment with endpoints C(6,-8) and D(-4,10) is calculated to be at (1, 1) by averaging the x and y coordinates of the endpoints.
Explanation:
The midpoint of a line segment with endpoints C(6,-8) and D(-4,10) can be found by averaging the x-coordinates and the y-coordinates of the two endpoints. To do this, add together the x-coordinates, 6 and -4, and divide by 2 to find the x-coordinate of the midpoint. Add together the y-coordinates, -8 and 10, and divide by 2 to find the y-coordinate of the midpoint.
The calculations are as follows:
x-coordinate: (6 + (-4)) / 2 = 1
y-coordinate: (-8 + 10) / 2 = 1
Therefore, the midpoint of CD is (1, 1).

What number is 21% more than 5/11?
Answer:
Step-by-step explanation:
21% more then 5/11...
5/11 + 21% of 5/11 = 5/11 + 0.21(5/11) = 5/11 + (21/100 * 5/11) =
5/11 + 21/220 = 11/20 <===
Firstly, we converted the fraction 5/11 to its decimal equivalent, which is approximately 0.4545. Then, we calculated a number that is 121% of 0.4545 (because 21% more than the original number means we have to count the original number plus the additional 21%). The calculation gave us approximately 0.5499.
Explanation:To answer this question, we can firstly calculate the equivalent decimal of 5/11. This can be done either by manual calculation or using a calculator. Dividing 5 by 11, we get approximately 0.4545.
Next, it's important to understand what the question is asking. When it asks what number is 21% more than a given number, it's essentially asking you to calculate a number that is 121% of the given number. Why? Because the original number (100%) plus the additional 21% gives you a total of 121%.
Once you know this, you simply multiply the given number (0.4545) by 1.21 (the decimal equivalent of 121%). And finally, multiplying 0.4545 by 1.21, we get approximately 0.5499. That is your final answer: The number that is 21% more than 5/11 is approximately 0.5499.

The question relates to finding the distance between two points in a coordinate system. The length of the line segment connecting vertex A (1,-1) and vertex B (1,4) of the triangle ABC can be calculated using the distance formula, which yields a result of 5 units.
Explanation:The subject of your question is geometry, specifically the concept of distance between two points in a coordinate system. In finding the length of the line segment that connects vertex A (1,-1) and vertex B (1,4), you can use the distance formula based on Pythagorean theorem.
The distance formula is d = sqrt [(x2 - x1)² + (y2 - y1)²]. In this case, x1 = 1, x2 = 1, y1 = -1 and y2 = 4.
Substituting these values, we have d = sqrt [(1 - 1)² + (4 - (-1))²] = sqrt [0 + 25], hence d = sqrt [25] = 5 units.
Therefore, the length of the line segment connecting vertex A (1, -1) and vertex B (1, 4) is 5 units.

There are 168 sweets altogether
Solution:Richard, Henry and Gavin share some sweets in the ratio 5 : 4 : 3
Let "5a" be the share of Richard
Let "4a" be the share of Henry
Let "3a" be the share of Gavin
Richard gets 70 sweets
share of Richard = 70
5a = 70
a = 14To find: number of sweets altogether
number of sweets altogether = share of richard + share of henry + share of gavin
number of sweets altogether = 5a + 4a + 3a
number of sweets altogether = 12a = 12(14) = 168
Thus there are 168 sweets altogether

For x=2, y=-10
inequality A
[tex]10(2) + 4(-10) < 12[/tex]
[tex]-20 < 12[/tex] ----> is true
inequality B
[tex]8(2)- 3(-10) > 20[/tex]
[tex]46 > 20[/tex] ---> is true
therefore
The point is a solution of the system of linear inequalities

Dan pays £220 per week in rent.
His landlord decides to increase the rent by 2.5%.
How much rent does he pay now? who ever is the first person wins iPhone x
Answer:
225.5
Step-by-step explanation:
220 + (2.5% × 220) =
220 + 2.5% × 220 =
(1 + 2.5%) × 220 =
(100% + 2.5%) × 220 =
102.5% × 220 =
102.5 ÷ 100 × 220 =
102.5 × 220 ÷ 100 =
22,550 ÷ 100 =
225.5
Answer:
225.5
Step-by-step explanation:
So, you would start by doing
220 times 2.5% that would equal 5.5
Then you would add
220 + 5.5 = 225.5
Therefore your answer will be 225.5
