<span>if a trip from earth to mars, is 97/186=.52150
and
a trip from earth to venus is 0.2774(now we have to times it by 2 since its a roundtrip),
we get .5548
we can clearly see that .5548>.52150
So roundtrip venus</span>
Supposed that we are given the equation:
7.20 x 10^-5 = x(0.100+x)^2
So assuming that x is very small so that:
0.100 + x ~ 0.100
and calling it x1, so:
7.20 x 10^-5 = x1 (0.100)^2
Then we simply solve for x1:
x1 = 7.20 x 10^-5 / (0.100)^2
<span>x1 = 7.20 x 10^-3</span>
Answer:
9.
Step-by-step explanation:
81/9=9
72/9=8
Answer:
Step-by-step explanation:
y = -4x - <u>8</u>
Any equation with an equal slope will be parallel to the line
Example: y = -4x or y = - 4x + 8
As long as the equation has a different y-intercept and equal slope it will be parallel!
Answer:
The expression is: 
The initial number of strands is 693
Step-by-step explanation:
A bacterial culture is known to grow at a rate proportional to the amount present.
This means that the bacterial model can be modeled by the following equation:
In which P(0) is the initial population, and r is the growth rate.
After one hour, there are 1000 strands of bacteria
This means that 
, So
After four hours, 3000 strands.
This means that P(4) = 3000. So
Since , we have that:
The initial population is:
The expression is:
