Step-by-step explanation:
Radius of outer circle = 6 m
Width of the track = 2 m
So, radius of inner circle = 6 - 2 = 4 m
Area of the track = Area of outer circle - Area of inner circle
\begin{gathered} = \pi {6}^{2} - \pi {4}^{2} \\ \\ = \pi( {6}^{2} - {4}^{2} ) \\ \\ = 3.14 \times (36 - 16) \\ \\ = 3.14 \times 20 \\ \\ = 62.8 \: {m}^{2} \end{gathered}

At 8 a.m. Anne left Austin and headed south at 20 mph. At 10 a.m. Gene left from the same place and headed south on the same road. If Anne was 10 miles ahead by 4 p.m. on the same day, what was Gene's speed in mph
Using proportions, it is found that Gene's speed was of 25 miles per hour, as he was 30 miles faster over a period of 6 hours.
What is a proportion?A proportion is a fraction of a total amount.
At 8 a.m. Anne left Austin and headed south at 20 mph, hence when Gene left at 10 a.m., she was 40 mph ahead.
At 4 p.m., that is, 6 hours after Gene left, the distance was of 10 miles, that is, Gene was 30 miles faster in 6 hours, so the difference in the speeds is given by:
d = 30/6 = 5 mph.
Since Anne's speed is of 20 mph, Gene's is given by:
v = 20 + 5 = 25 mph.

Mike is working on solving the exponential equation 74^x = 37; however, he is not quite sure where to start. Using complete sentences, describe to Mike how to solve this equation.
Answer:
Method 1
[tex]74^x = 37[/tex]
Take natural logs of both sides:
[tex]\implies \ln74^x = \ln37[/tex]
Apply the log power rule: [tex]\ln(a)^b=b \ln (a)[/tex]
[tex]\implies x\ln74 = \ln37[/tex]
Divide both sides by ln 74:
[tex]\implies \dfrac{x\ln74}{\ln74} = \dfrac{\ln37}{\ln74}[/tex]
[tex]\implies x= \dfrac{\ln37}{\ln74}[/tex]
[tex]\implies x=0.8389552282...[/tex]
Method 1
[tex]74^x = 37[/tex]
Take logs of base 74 of both sides:
[tex]\implies \log_{74}74^x = \log_{74}37[/tex]
Apply the log power rule: [tex]\log_am^n=n\log_am[/tex]
[tex]\implies x\log_{74}74= \log_{74}37[/tex]
Apply log of the same number as base rule: [tex]\log_aa=1[/tex]
[tex]\implies x= \log_{74}37[/tex]
[tex]\implies x=0.8389552282...[/tex]
Answer:
[tex]x = \log_{74}(37) [/tex]
Step-by-step explanation:
we want to solve the following exponential equation:
[tex] \iff {74}^{x} = 37[/tex]
Taking common logarithm of both sides yields:
[tex]\iff \log{74}^{x} = \log37[/tex]
recall that,
[tex] log( {a}^{x} ) = x log(a) [/tex]utilizing it yields:
[tex] \iff x \cdot\log{74} = \log37[/tex]
divide both sides by log74:
[tex]\iff \dfrac{ x \cdot\log{74}}{ \log(74)} = \dfrac{ \log37}{ \log(74) }[/tex]
remember that,
[tex] log_b( {a} ) = \frac{log(a)}{log(b)} [/tex]
hence,
[tex]x = \boxed{ \log_{74}(37)} [/tex]

Choice A
Step-by-step explanation:
End of the question states it, and I did it on Khan :)
Kara finds that the top 200200200 longest streaks in the world in June had an average of about 636363 so option (A) will be correct.
What is mean?The mean is the average of a data set. Mean gives us the idea of that how much amount of overall data have.
In other words, the mean is the foundation of the deviation of data from all data sets.
Mean = sum of data / Number of data
For example, if you have marks in 5 subjects like 40,45,44,46,48 then the mean will be
( 40 + 45+ 44 + 46 + 48) /5 = 44.6.
Given that,
Kara finds that the top 200200200 longest streaks in the world in June had an average of about 636363 wins in a row
It means the top 200200200 longest streaks worldwide in June have an average longest streak of 636363.
Hence " Kara finds that the top 200200200 longest streaks in the world in June had an average of about 636363".

If the graph of f '(x) has an X-intercept at x = C, which of the following must be true?
A. The graph off has a relative minimum or relative maximum at x = C.
B. The graph off has an inflection point at x = C.
C. The graph off has an x-intercept at x = C.
D. None of the above is necessarily true.
Answer: D
Step-by-step explanation:
f'(C) = 0 ⇒ There is a critical point here
There could be a relative max or min here, but since we do not know if f''(x) is positive or negative, we cannot be sure if the function is truly changing from positive to negative or vice versa. "C" could simply be at a horizontal tangent of a function like x³.

Answer: The first term of a GP is 6 if it's common ratio is 2 find the 6th term
The nth term is ar^(n-1)
So, for your GP, the 6th term is 6*2^5 = ___
Step-by-step explanation: 10:2021
The value of 16th term in the geometric series is,
⇒ 6th term = 192
What is Geometric sequence?An sequence has the ratio of every two successive terms is a constant, is called a Geometric sequence.
Given that;
The first term is 6 and the common ratio is 2.
Hence, We can formulate;
⇒ nth term = arⁿ⁻¹
⇒ 6th term = ar⁶⁻¹
⇒ 6th term = ar⁵
⇒ 6th term = 6 (2)⁵
⇒ 6th term = 6 x 32
⇒ 6th term = 192
Thus, The value of 16th term in the geometric series is,
⇒ 6th term = 192

Step-by-step explanation:
The first shelf is x. The second shelf is y. The third shelf is z.
x+y=54.
y+z=57
x+y+z=88
You can substitute 54 in for x+y in the third equation to solve for z.
54+z=88
Subtract 54
z=34
Now that you know z, substitute it in in the second equation.
y+34=57
y=23
Finally, substitute the known y value into the first equation.
x+23=54

Answer:
[tex]\displaystyle \cos x \left(\csc x + \tan x\right) = \cot x + \sin x[/tex]
Step-by-step explanation:
We want to simplify:
[tex]\displaystyle \cos x \left(\csc x + \tan x\right)[/tex]
Recall that csc x = 1 / sin x and tan x = sin x / cos x. Substitute:
[tex]\displaystyle = \cos x \left(\frac{1}{\sin x} + \frac{\sin x }{\cos x}\right)[/tex]
Distribute:
[tex]\displaystyle = \frac{\cos x}{\sin x} + \frac{\cos x \sin x}{\cos x} \\ \\ \\ = \frac{\cos x}{\sin x} + \sin x[/tex]
Recall that cot x = cos x / sin x. Hence:
[tex]\displaystyle = \cot x + \sin x[/tex]
In conclusion:
[tex]\displaystyle \cos x \left(\csc x + \tan x\right) = \cot x + \sin x[/tex]
