Answer:
punany because the circular circumstances say that it is correct
Step-by-step explanation:
Answer:
The number written in standard form is ![131,480,000](https://tex.z-dn.net/?f=131%2C480%2C000)
Step-by-step explanation:
we have
![1.3148*10^8](https://tex.z-dn.net/?f=1.3148%2A10%5E8)
we know that
![10^8=100,000,000](https://tex.z-dn.net/?f=10%5E8%3D100%2C000%2C000)
substitute
![1.3148*10^8=1.3148(100,000,000)](https://tex.z-dn.net/?f=1.3148%2A10%5E8%3D1.3148%28100%2C000%2C000%29)
Remember that
When multiplying decimals by 10, move the decimal point one space to the right
In this case move the decimal point eight spaces to the right
![1.3148(100,000,000)=131,480,000](https://tex.z-dn.net/?f=1.3148%28100%2C000%2C000%29%3D131%2C480%2C000)
therefore
The number written in standard form is ![131,480,000](https://tex.z-dn.net/?f=131%2C480%2C000)
A geometric sequence can always be expressed as:
a(n)=ar^(n-1), a=initial value, r=common ratio, n=term number
We are told that a(5)=25 and r=5 so we can say:
25=a5^(5-1)
25=a5^4
25=625a
a=1/25 so now we know our explicit formula for this geometric sequence:
a(n)=(1/25)(5^(n-1)) and the first three terms will be a(1), a(2), and a(3)
1/25, 1/5, 1
Your answer would be -27mm square
