The midpoint of BC is (5, -2). One endpoint is B (3,4). What are the coordinates of endpoint C?
Let the midpoint of [tex]BC[/tex] be [tex]M(x_{_M};~y_{_M})[/tex].
Then [tex]x_{_M}=\dfrac{x_{_B}+x_{_C}}{2}[/tex] and [tex]y_{_M}=\dfrac{y_{_B}+y_{_C}}{2}[/tex].
We are given [tex]x_{_M}=5, y_{_M}=-2[/tex] and [tex]x_{_B}=3, y_{_B}=4[/tex].
[tex]5=\dfrac{3+x_{_C}}{2}\Rightarrow x_{_C}=7\medskip\\{-2}=\dfrac{4+y_{_C}}{2}\Rightarrow y_{_C}=-8[/tex]
[tex]C(7;-8)[/tex]
Answer:
The coordinates of endpoint C are (7,-8).
Step-by-step explanation:
Given information: Midpoint of BC is (5, -2) and B(3,4).
We need to find the coordinates of C.
Let the coordinate of C are (x,y).
If end points of a line segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the midpoint of that segment is
[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Midpoint of BC is
[tex]Midpoint=(\frac{3+x}{2},\frac{4+y}{2})[/tex]
Midpoint of BC is (5,-2).
[tex](5,-2)=(\frac{3+x}{2},\frac{4+y}{2})[/tex]
On comparing both sides.
[tex]5=\frac{3+x}{2}[/tex]
[tex]10=3+x[/tex]
[tex]10-3=x[/tex]
[tex]7=x[/tex]
The value of x is 7.
[tex]-2=\frac{4+y}{2}[/tex]
[tex]-4=4+y[/tex]
[tex]-4-4=y[/tex]
[tex]-8=y[/tex]
The value of y is -8.
Therefore the coordinates of endpoint C are (7,-8).
For which value of x is the figure a rectangle?
A. x = -1
B. x = 11
C. x = 11.5
D. x = 22.25
Answer:
The value of x is 11.
Option (B) is correct.
Step-by-step explanation:
By using the property of the rectangle .
In rectangle all four angles are 90° .
As the figure given in the question .
Thus
(5x + 2) + 3x = 90
Open the bracket
5x + 2 + 3x = 90
8x + 2 = 90
8x = 90 - 2
8x = 88
[tex]x = \frac{88}{8}[/tex]
x = 11
Therefore the value of x is 11.
Option (B) is correct.

To evaluate a function at a given input, you have to substitute every occurrence of the variable with that particular value.
So, for the first function, you have
[tex] T(x) = -x-2 \implies T(-4) = -(-4)-2 = 4-2 = 2 [/tex]
The name of the variable is obviously irrelelvant, so the same goes for the second function:
[tex] w(x) = 14-6x \implies w(-3) = 14-6\cdot(-3) = 14 + 18 = 32 [/tex]
T(-4) = -(-4) - 2
-(-4) - 2 = 2

Teresa graphs the following 33 equations: y=2x, y=x2+2, and y=2x^2. She says that the graph of y=2^x will eventually surpass both of the other graphs. Is Teresa correct? Why or why not?
she is correct because the graph of y=2^2 will surpass the other 2 lines on the graph.
Teresa is correct as the graph of the exponential function y=2^x increases more rapidly than those of the linear and quadratic functions when x becomes large. Thus, y=2^x will eventually surpass the other graphs.
Explanation:Teresa's statement that the graph of y=2^x will eventually surpass the other graphs of y=2x, y=x^2+2, and y=2x^2 is correct. This is because the graph of an exponential function such as y=2^x increases more rapidly than the graphs of linear or quadratic functions when the value of x becomes large.
For example, plotting data pairs for each of these equations, we would see that as x increases, the value of y for y=2^x will eventually be greater than the y-values for the other functions. While y=2x and y=x^2+2 will also increase with larger x, the growth rate is not as extreme as for the exponential function y=2^x.
To further illustrate, for very large values of x, the quadratic function y=2x^2 increases slower than the exponential function y=2^x. Therefore, understanding the characteristics of linear, quadratic, and exponential functions is essential in interpreting these graphs correctly.

An Uber fare in Columbus is $3.50 for the first ½ mile and additional mileage charged at a rate of $0.30 for each additional 0.1 mile. You plan to give the driver a $2 tip. How many miles can you ride for $15? Please show or explain your calculations.please i need help on this.
Answer:
[tex]\frac{11}{3}[/tex] miles
Step-by-step explanation:
Let the total miles traveled be x.
Now, for the first 0.5 miles total charge is = $3.50
Then, the remaining distance to be traveled[tex]=(x-0.5)[/tex] miles
For each additional 0.1 mile, the additional charge is $0.30
So, for [tex](x-0.5)[/tex] miles, the total additional charge will be[tex]=\frac{0.3}{0.1}(x-0.5) =3(x-0.5)[/tex]
Then, including the $2 tip, the total fare will be[tex]=3.50+3(x-0.5)+2[/tex]
Now, given that total fare is $15, so,
[tex]3.50+3(x-0.5)+2=15\\3.50+3x-1.5+2=15\\3x+4=15\\3x=11\\x=\frac{11}{3}[/tex]miles
Let's assume, total number of miles traveled after the first 0.5 mile are x.
For 0.1 mile, the cost is $0.30
[tex]0.1\times 10 = 1 mile[/tex]
Hence, for 10 miles, cost is
[tex]0.30\times 10 = 3[/tex] dollars
Total amount incurred = $ 3.50 (fixed cost) + 3x (cost per mile) + 2( tip)
He gave a total of $ 15, hence
[tex]15=3.50+3x+2[/tex]
[tex]9.5=3x[/tex]
[tex]x=\frac{95}{30} =\frac{19}{6}[/tex] miles
Total miles traveled = [tex]\frac{19}{6} +\frac{1}{2}[/tex] =[tex]\frac{11}{3}[/tex] miles

Jay has $25 to spend at a comic book store. If he buys a collectors guide for &12, what is the greatest number of individual comics he can by at $2 each?
After buying a collectors guide for $12, Jay can use the remaining $13 to purchase a maximum of 6 individual comics at $2 each.
Jay has a total of $25 to spend on comic books after purchasing a collectors guide for $12. To calculate the greatest number of individual comics he can buy at $2 each, we subtract the cost of the collector's guide from his total budget:
$25 - $12 = $13 remaining
Each comic book costs $2, so we divide the remaining amount by the cost of one comic book:
$13 / $2 = 6.5
Since Jay cannot buy half a comic book, he can purchase a maximum of 6 comics.
The mean score on a driving exam for a group of driver's education students is 80 points, with a standard deviation of 3 points. Apply Chebychev's Theorem to the data using k=2. Interpret the results.
Applying Chebyshev's theorem with a mean of 80 and a standard deviation of 3 to k=2, we find that at least 75% of exam scores should fall between 74 and 86 points.
Explanation:Chebyshev's Theorem states that at least [tex]1 − 1/k^2[/tex](where 'k' is any real number greater than 1) of data from a sample will fall within 'k' standard deviations from the mean. Given that the mean score on the driving test is 80 points and the standard deviation is 3 points, we apply Chebyshev's theorem with k=2 (2 standard deviations from the mean).
Now let's do the calculations. The formula for Chebyshev’s Theorem is [tex]1 – 1/k^2[/tex], so that gives us[tex]1 - 1/2^2 = 1[/tex] - 1/4 = 0.75 or 75%.
Also, to find the range within which 75% of the results will fall, we use the mean and standard deviation, which gives us 'mean ± k standard deviations' => 80 ± 2*3 => [74, 86].
In conclusion, Chebyshev's theorem predicts that at least 75% of the scores on the driving test should be between 74 and 86 points.

At 3:00 PM a man 138 cm tall casts a shadow 148 cm long. At the same time, a tall building nearby casts a shadow 199 m long. How tall is the building?
To find the height of the building, we can use the concept of similar triangles and set up a proportion. Substituting the given values and solving for x, we find the height of the building to be approximately 186.5 meters.
Explanation:To find the height of the building, we can use the concept of similar triangles. Let's set up a proportion using the man's height and shadow length, and the building's height and shadow length. We have:
(Man's Height)/(Man's Shadow Length) = Building's Height/(Building's Shadow Length)
Substituting the given values, we have:
(138 cm)/(148 cm) = x/(199 m)
Cross-multiplying and solving for x, we find the height of the building to be approximately 186.5 meters.

The subject of this question is Mathematics. Emerson's strikeout rate is 32%.
Explanation:The subject of this question is Mathematics as we are dealing with numerical data. We are given that Emerson struck out 112 times in 350 at-bats.
To find the strikeout rate, we divide the number of strikeouts by the number of at-bats and multiply by 100 to get a percentage. So, the strikeout rate would be (112/350) * 100 = 32%.
Therefore, Emerson's strikeout rate is 32%.
