Answer:
option A. 21 sec
Step-by-step explanation:
Speed = the distance over the time
Given:
Speed = 2 m/s and distance = 42 m and time = t
So,
2 = 42/t
Solve for t
t = 42/2 = 21 sec.
The answer is option A. 21 sec
Answer:
Exponential functions!
Step-by-step explanation:
I think what you are dealing with is an exponential function!
So, to solve this, we need to first understand the main form of an exponential function:

Where a is the number we start off with, and b is the constant thing(forgot what it was called).
Now, 150 is our starting number, so it is a, and b is our constant at which the initial term is multiplied, which is 3!
Also, defining variables:
Let f(x)= # of Bees
Let x= # of years
Thus, here is our equation:

So, that's it!

Answer:
you simplify the fractions then you cross multiply
Step-by-step explanation:
1/2 * 4/2 you multiply 1 and 4 and you get 4/4 which is equal to 1
3(4m-2)-2(m+5)
Distribute.
12m-6-2m-10
12m-2m= 10m
-6-10= -16
10m-16
I hope this helps!
