Answer:
(x+1)²+(y-5.5)²=11.25
Step-by-step explanation:
1) the common view is:
(x-x₀)²+(y-y₀)²=r², where x₀, y₀ - coordinates of the centre, r - the length of the radius;
2) the coordinates of the centre can be calculated:
[tex]x_0=\frac{2-4}{2}=-1; \ y_0=\frac{4+7}{2}=5.5.[/tex]
3) the length of the radius is:
[tex]r=\sqrt{(-1-2)^2+(5.5-4)^2}=\sqrt{11.25}.[/tex]
4) if the centre is (-1;5.5) and r²=11.25, then it is possible to make up the required equation:
(x+1)²+(y-5.5)²=11.25
Answer:
The other answer is WRONG. INCORRECT. NON-RIGHT! My answer is correct, do NOT delete it. The correct answer is (x+1)^2 + (y-11/2)^2 = 45/4. This is how the system wants it! Want proof? I have this question and all others screenshoted for your convenience.

When 848 is divided by n, the result is 16.
Answer:
n = 53
Step-by-step explanation:
Write the equation like this to find the answer.
848/n = 16 (Multiply each side by n to get 848 by itself)
848 = 16n (divide each side by 16 to get n by itself)
53 = n
CHECK
848/53 = 16
16 = 16

Suppose you have £20,000 in cash to invest. You decide to short sell £10,000 worth of Coca-Cola and invest the proceeds from your short sale plus your £20,000 in Intel. The initial price of Coca-Cola is £40 and increases to £42.40 producing a return of 6%. The initial price of Intel is £25 and increases to £31.50 producing a return of 26%. How many shares of Coca-Cola have you short sold and how many shares of Intel do you currently have? Select one: a. Short sold 2,000 shares of Coca cola and invested in 80 shares of Intel b. Short sold 40 shares of Coca cola and invested in 400 shares of Intel c. Short sold 250 of Coca cola and invested in 1200 shares of Intel d. Short sold 300 of Coca cola and invested in 12000 shares of Intel
Answer:
hdshdhdbs sorry
Step-by-step explanation:
The number of shares of Coca-Cola short sold and number of Intel shares bought are c. Short sold 250 of Coca cola and invested in 1200 shares of Intel.
Data and Calculations:
Cash available for investment = £20,000
Proceeds from short sale of Coca-Cola = £10,000
Total funds available for investment = £30,000
Initial price of Coca-Cola per share = £40
Number of Coca-Cola shares short sold = 250 (£10,000/£40)
Initial price of Intel stock per share = £25
Number of Intel shares acquired = 1,200 shares (£30,000/£25)
Thus, you short sold 250 shares of Coca-Cola stock and invested in 1,200 shares of Intel stock.

A. translation 4 units to the left
B. reflection over the y axis
C. dilation with a scale factor of 2
D. rotation of 270 degrees clockwise
Answer:
C
Step-by-step explanation:
The answer would be C because dilation ( unless by 1 ) doesn't preserve congruence so every other answer that isn't dilation would be right and C would be the answer because the factor is 2 not 1.

The Smith family went to the theater
to see a movie. Adult tickets cost
$12 and child tickets cost $9. If they
spent $72 total and purchased 7
tickets, how many of each
were purchased
Answer:
3 adult tickets and 4 child tickets
Step-by-step explanation:
a + k = 7
a = 7 - k
12a + 9k = 72
12a + 9k = 72
12(7 - k) + 9k = 72
84 - 3k = 72
84 - 3k = 72
3k = 12
k = 4
a = 3
The number of adult tickets purchased is 3 and the number of child tickets purchased is 4.
Given that, adult tickets cost $12 and child tickets cost $9.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
If they spent $72 total and purchased 7 tickets.
Let the number of adult tickets be x, then the number of children tickets will be 7-x.
Now, 12x+9(7-x)=72
⇒ 12x+63-9x=72
⇒ 3x=72-63
⇒ 3x=9
⇒ x=3
So, 7-x=4
Therefore, the number of adult tickets purchased is 3 and the number of child tickets purchased is 4.

Geometric Sequence S = 1.0011892 + ... + 1.0012 + 1.001 + 1
Answer:
[tex]S_{1893} =5632.98[/tex]
Step-by-step explanation:
The correct form of the question is:
[tex]S = 1.001^{1892} + ... + 1.001^2 + 1.001 + 1[/tex]
Required
Solve for Sum of the sequence
The above sequence represents sum of Geometric Sequence and will be solved using:
[tex]S_n = \frac{a(1 - r^n)}{1 - r}[/tex]
But first, we need to get the number of terms in the sequence using:
[tex]T_n = ar^{n-1}[/tex]
Where
[tex]a = First\ Term[/tex]
[tex]a = 1.001^{1892}[/tex]
[tex]r = common\ ratio[/tex]
[tex]r = \frac{1}{1.001}[/tex]
[tex]T_n = Last\ Term[/tex]
[tex]T_n = 1[/tex]
So, we have:
[tex]T_n = ar^{n-1}[/tex]
[tex]1 = 1.001^{1892} * (\frac{1}{1.001})^{n-1}[/tex]
Apply law of indices:
[tex]1 = 1.001^{1892} * (1.001^{-1})^{n-1}[/tex]
[tex]1 = 1.001^{1892} * (1.001)^{-n+1}[/tex]
Apply law of indices:
[tex]1 = 1.001^{1892-n+1}[/tex]
[tex]1 = 1.001^{1892+1-n}[/tex]
[tex]1 = 1.001^{1893-n}[/tex]
Represent 1 as [tex]1.001^0[/tex]
[tex]1.001^0 = 1.001^{1893-n}[/tex]
They have the same base:
So, we have
[tex]0 = 1893-n[/tex]
Solve for n
[tex]n = 1893[/tex]
So, there are 1893 terms in the sequence given.
Solving further:
[tex]S_n = \frac{a(1 - r^n)}{1 - r}[/tex]
Where
[tex]a = 1.001^{1892}[/tex]
[tex]r = \frac{1}{1.001}[/tex]
[tex]n = 1893[/tex]
So, we have:
[tex]S_{1893} =\frac{1.001^{1892} *(1 -\frac{1}{1.001}^{1893})}{1 -\frac{1}{1.001} }[/tex]
[tex]S_{1893} =\frac{1.001^{1892} *(1 -\frac{1}{1.001}^{1893})}{\frac{1.001 -1}{1.001} }[/tex]
[tex]S_{1893} =\frac{1.001^{1892} *(1 -\frac{1}{1.001}^{1893})}{\frac{0.001}{1.001} }[/tex]
[tex]S_{1893} =\frac{1.001^{1892} *(1 -\frac{1}{1.001^{1893}})}{\frac{0.001}{1.001} }[/tex]
Simplify the numerator
[tex]S_{1893} =\frac{1.001^{1892} -\frac{1.001^{1892}}{1.001^{1893}}}{\frac{0.001}{1.001} }[/tex]
[tex]S_{1893} =\frac{1.001^{1892} -1.001^{1892-1893}}{\frac{0.001}{1.001} }[/tex]
[tex]S_{1893} =\frac{1.001^{1892} -1.001^{-1}}{\frac{0.001}{1.001} }[/tex]
[tex]S_{1893} =(1.001^{1892} -1.001^{-1})/({\frac{0.001}{1.001} })[/tex]
[tex]S_{1893} =(1.001^{1892} -1.001^{-1})*{\frac{1.001}{0.001}}[/tex]
[tex]S_{1893} =\frac{(1.001^{1892} -1.001^{-1}) * 1.001}{0.001}[/tex]
Open Bracket
[tex]S_{1893} =\frac{1.001^{1892}* 1.001 -1.001^{-1}* 1.001 }{0.001}[/tex]
[tex]S_{1893} =\frac{1.001^{1892+1} -1.001^{-1+1}}{0.001}[/tex]
[tex]S_{1893} =\frac{1.001^{1893} -1.001^{0}}{0.001}[/tex]
[tex]S_{1893} =\frac{1.001^{1893} -1}{0.001}[/tex]
[tex]S_{1893} =5632.97970294[/tex]
Hence, the sum of the sequence is:
[tex]S_{1893} =5632.98[/tex] ----- approximated
