Answer:
y = x - 3
Step-by-step explanation:
Answer:
the 5 that is 1st is in hundredths place the second on is the the tenth place and the last one is in the oneths place
Step-by-step explanation:
900 x² + 500 x= 1600 /:100
9 x² + 5 x = 16
9 x² + 5 x - 16 = 0
x 1/2 =
![\frac{-5\pm \sqrt{5^{2}-4*9*16 } }{18} = \frac{-5\pm \sqrt{25+576} }{18}= \\ = \frac{-5+24.52}{18}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-5%5Cpm%20%5Csqrt%7B5%5E%7B2%7D-4%2A9%2A16%20%7D%20%7D%7B18%7D%20%3D%20%20%5Cfrac%7B-5%5Cpm%20%5Csqrt%7B25%2B576%7D%20%7D%7B18%7D%3D%20%5C%5C%20%3D%20%5Cfrac%7B-5%2B24.52%7D%7B18%7D%20%20)
x = 1.084
The interest rate:
r = x - 1 = 1.084 - 1 =
0.084 = 8.4 %Answer: D) 8.4 %
Scientific notation is a number greater than 0 and less than 10 multiplied by 10 to a power. The expression will be equal to the number given.
91007500
We move the decimal place first so that the number is within our range:
9.1007500
Then we count how many places we moved the decimal. In this case we moved it to the left 7 times, so our exponent of 10 will be 7
Therefore in scientific notation it is 9.1007500 x 10^7
Some teachers prefer to have scientific notation rounded off to the nearest 10th place, so that would be:
9.1 x 10^7
