Answer: f(x) = 4 / (√x-13)
Step-by-step explanation:
Hi, the question is missing this part:
Find an expression for f(x)
To write the expression we have to analyze the information given:
<em>f is a function that takes a real number x</em> : f(x)
<em>(1) take the square root:</em> f(x) = √x
<em>(2) subtract 13 </em>: f(x) = √x-13
<em>(3) make the quantity the denominator of a fraction with numerator 4.</em>
f(x) = 4 / (√x-13)
In conclusion, the expression for f(x) is ⇒f(x) = 4 / (√x-13)
Feel free to ask for more if needed or if you did not understand something.
Answer:
7.75
Step-by-step explanation:
12. 45
This is because you can use the Pythagorean Theorem to find the last side. Since we know the radius is 24, we can tell that BO is 51. Using that as the hypotenuse, you can find that AB is equal to 45. <span />
Answer:
The 4th term is -37.
Step-by-step explanation:
The first term of the series is
,
the second term of the series is
![a_2 =2a_1-3](https://tex.z-dn.net/?f=a_2%20%3D2a_1-3)
![a_2=2(-2)-3\\\\a_2=-7,](https://tex.z-dn.net/?f=a_2%3D2%28-2%29-3%5C%5C%5C%5Ca_2%3D-7%2C)
the third term is
![a_3 = 2a_2-3](https://tex.z-dn.net/?f=a_3%20%3D%202a_2-3)
![a_3=2(-7)-3](https://tex.z-dn.net/?f=a_3%3D2%28-7%29-3)
,
and the fourth term of the series is
![a_4=2a_3-3\\](https://tex.z-dn.net/?f=a_4%3D2a_3-3%5C%5C)
![a_4=2(-17)-3](https://tex.z-dn.net/?f=a_4%3D2%28-17%29-3)
![\boxed{a_4=-37}](https://tex.z-dn.net/?f=%5Cboxed%7Ba_4%3D-37%7D)
