2/10 is one example of a fraction equal to 1/5
Answer:
you have to round up so it would round up to 35.800
Step-by-step explanation:
Answer:
y = 2
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° =
, then
sin45° =
=
=
( cross- multiply )
y = (
)² = 2
Answer:
Marco- 10 is the starting value of the population. 2 is the growth rate of "double each day" with d as an exponent.
Isabella- 1 is the starting population. 1+0.2=1.2 is the rate at which it grows each day.
Step-by-step explanation:
Marco's equation should be
since the bacteria double each day. 10 is the starting value of the population. 2 is the growth rate of "double each day" with d as an exponent. This will double each day because:
Day 1 is ![2^{1}=2](https://tex.z-dn.net/?f=2%5E%7B1%7D%3D2)
Day 2 is ![2^{2}=4](https://tex.z-dn.net/?f=2%5E%7B2%7D%3D4)
Day 3 is ![2^{3}=8](https://tex.z-dn.net/?f=2%5E%7B3%7D%3D8)
Day 4 is ![2^{4}=16](https://tex.z-dn.net/?f=2%5E%7B4%7D%3D16)
You'll notice the value doubles each day.
Isabella has a different equation because her population increases by a percentage. We use the simple interest formula to calculate the bacteria's daily increase or interest.
1(1+0.2)d
1 is the starting population.
1+0.2=1.2 is the rate at which it grows each day.
