Answer:
Sin(E) =
Step-by-step explanation:
The full question is as follows :
To find - In the accompanying diagram, what is sin E?
Proof -
We know that,
Sin(theta) = (opposite side) / (hypotenuse)
From the diagram, we can see that,
Base = 3
Perpendicular = 5
Hypotenuse = 5
So,
For angle E,
Opposite side = 4
Hypotenuse = 4
∴ we get
Sin(E) =
Answer:
The missing value is 128
Step-by-step explanation:
we know that
The equation of the exponential function is of the form
where
a is the initial value (value of the function when the value of x is equal to zero)
b is the base
r is the rate
b=(1+r)
In this problem , looking at the table, we have that the number of bacteria is doubled every second
so
substitute in the formula
where
f(x) is the number of bacteria
x is the time in seconds
For x=4 sec
substitute
