Answer:
67.5$
Step-by-step explanation:
75$ x .10 = 7.5$
75$ - 7.5$ = 67.5$
Two figures are similar if they have the same shape but not necessarily the same size although they are the same shape they are different sizes
Multiplying and Dividing Exponents are very easy.
When they are multiplied, we add the exponent numbers together.
When they are divided, we subtract the exponent numbers.
In this example,
![h^{-18}* h^3](https://tex.z-dn.net/?f=h%5E%7B-18%7D%2A%20h%5E3)
/
![h^{0}](https://tex.z-dn.net/?f=%20h%5E%7B0%7D%20)
We can conclude that
![h^{0}](https://tex.z-dn.net/?f=%20h%5E%7B0%7D%20)
is 1 because,
any number to the power of 0 is 1
![\frac{ h^{-18}* h^{3} }{1}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20h%5E%7B-18%7D%2A%20%20h%5E%7B3%7D%20%7D%7B1%7D%20)
=
![h^{-18} * h^{3}](https://tex.z-dn.net/?f=%20h%5E%7B-18%7D%20%2A%20%20h%5E%7B3%7D%20)
take the exponents alone:
-18+3 (Because it is multiplication) =-15
Final answer
: ![h^{-15}](https://tex.z-dn.net/?f=%20h%5E%7B-15%7D%20)

Answer:
71.447296
Step-by-step explanation:
The sequence is geometric with first term 100 and common ratio -0.4. Then the sum of n terms is ...
Sn = 100(1 -(-0.4)^n)/(1 -(-0.4))
and the sum of 9 terms is ...
S9 = 100(1 -(-0.4^9))/(1.4) = 71.447296
