Answer:
multiple and divide are depending on the powers ( sometimes the numbers before the scientific n.)
If the power neg- , it's going down
like this 10^-5 = 1/10^5
If the power pos+ , it's the same idea but different in signs .
Adding and subtracting are depending on numbers ( If the scientific n. is the same number) .
for example:
3x10^5 + 4x10^5 = (3+4)x10^5 = 7x10^5
Answer:
its a combination problem, so in your calculator put 9 nCr 4 and you'll get 126. i hope this helps. :)

Answer:
a) P(t) = 6.29e^(0.0241t)
b) P(6) ≈ 7.3 million
c) 10 years
d) 28.8 years
Step-by-step explanation:
a) You have written the equation.
P(t) = 6.29·e^(0.0241·t)
__
b) 2018 is 6 years after 2012.
P(6) = 6.29·e^(0.0241·6) ≈ 7.2686 ≈ 7.3 . . . million
__
c) We want t for ...
8 = 6.29·e^(0.0241t)
ln(8/6.29) = 0.0241t
t = ln(8/6.29)/0.0241 ≈ 9.978 ≈ 10.0 . . . years
__
d) Along the same lines as the calculation in part (c), doubling time is ...
t = ln(2)/0.0241 ≈ 28.7613 ≈ 28.8 . . . years
Answer:
The slope is 
Step-by-step explanation:
we know that
The equation of the line into slope intercept form is equal to

where
m is the slope
b is the y-coordinate of the y-intercept
In this problem we have

so
Convert to slope intercept form
Isolate the variable y



The slope is 
Assuming you meant square root of 90 it would be
90 equals 3 times the square root of 10
√90 = 3√10
