Answer:
![a_1=4](https://tex.z-dn.net/?f=a_1%3D4)
Step-by-step explanation:
Given a G.P series i.e geometric sequence
4, −16, 64, −256, ...
We have to find the recursive rule for the geometric sequence.
We know that
is the first term of the sequence.
Here ![a_1=4](https://tex.z-dn.net/?f=a_1%3D4)
As, the nth term of Geometric progression is
where r is the common ratio
![\text{Common ratio=r=}\frac{a_2}{a_1}=\frac{-16}{4}=-4](https://tex.z-dn.net/?f=%5Ctext%7BCommon%20ratio%3Dr%3D%7D%5Cfrac%7Ba_2%7D%7Ba_1%7D%3D%5Cfrac%7B-16%7D%7B4%7D%3D-4)
Hence the recursive formula is
Answer:
$18.5685 or $18.56
Step-by-step explanation:
The answer is $18.56 because 123.79 multiplied by 15% is $18.56
One day 6 said, "I wish I were an adult." And 1/3 came along and said, "I can do a magic flip! If I do this special flip and you're brave enough to combine our powers together we'll be 18!" 6 thought this was a brilliant idea so 1/3 flipped on his head and turned into a 3 and when 6
Hence the required function of h i.e f(h) is expressed as
![f(x) = \frac{1}{x^2-3}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B1%7D%7Bx%5E2-3%7D)
Given the expression
![f(x) = \frac{1}{x^2-3}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B1%7D%7Bx%5E2-3%7D)
To get f(h), we will substitute f in place of x as shown;
![f(h) = \frac{1}{h^2-3}](https://tex.z-dn.net/?f=f%28h%29%20%3D%20%5Cfrac%7B1%7D%7Bh%5E2-3%7D)
Hence the required function of h i.e f(h) is expressed as
![f(x) = \frac{1}{x^2-3}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B1%7D%7Bx%5E2-3%7D)
