Answer:
Simplifies to 4k - 32
Step-by-step explanation:
To solve, translate the word problem into an equation:
"A number K" - k
"decreased by eight" - subtract 8 or k - 8
"the result is multiplied by eight" - multiply 8(k - 8)
"this product is then divided by two" - divide by 2 or 8(k - 8)/2.
8(k - 8) / 2 = 4(k - 8) = 4k - 32.
The simplified form is 4k - 32. To find a final numerical result, substitute any number for k and apply the equation.
Answer:
-2/3

= -2/3
Answer:
972 is the population of rabbits in the year 5
Step-by-step explanation:
is an increasing exponential function of base 3. The fact that its base is 3 means that the function triples when x increases one unit.
It is said that the population triples every year. Therefore x represents the number of years elapsed and f(x) represents the number of rabbits in year x
If f(x) represents the population of rabbits for the year x, then, f(5) represents the population of rabbits for x = 5, that is to say, after having passed 5 years.
So, 972 is the population of rabbits in the year x = 5
So he started at
9:30 a.m.
three hours and ten minutes later
9+3 is 12
30 + 10 is 40
12:40 p.m.
it took him 47 minutes to replace
so 12:40 plus 47 minutes is
1:27 p.m.
He then rode for another 56 minutes to finish the race
so 1:27 plus 56 minutes
2:23 p.m.
Hope this helps :)
