Answer:
A. 16 seconds.
Step-by-step explanation:
Well, it would take him 4 seconds to get 4/16 of the way, or 1/4. So just multply that by 4 and boom, 16 seconds. (yes ik my technique is weird)
Answer:
x=1.5
Step-by-step explanation:
- 5=10(5x-7)
- 0.5=5x-7
- 7.5=5x
- x=1.5
Answer:
<h2>D. g(x) = (x - 4)²</h2>
Step-by-step explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x - n) - shift the graph n units to the right
f(x + n) - shift the graph n units to the left
=========================================
The graph of f(x) shifted by 4 units to the right. Therefore, the equation g(x) is:
g(x) = f(x - 4) = (x -4)²
Answer:

Step-by-step explanation:
There are 1,000 milliliters in a liter. This means that in order to convert 600 liters to milliliters, you must multiply 600 by 1,000.
600 x 10^3 mL simplifies to 600 x 1,000 mL
The last expression is also 600 x 1,000 mL
The incorrect expression is the first one, since it is only multiplying by 100 mL instead of 1,000.
The number of cows is given by

So, after
years, the number of cows will be

We want this number to be twice as much as the original:

First of all, we can cancel 14 from both sides:

Finally, on the right hand side, we can use the exponent rule

to get

To solve this equation, we must impose that the two exponents are the same:

And clearly this is true if and only if
. So, it will take 5 years for the cow heard to double in number.
You can do the exact same steps to find the doubling time for the sheeps.
