Answer:
k=6,912
Step-by-step explanation:
5678+1234=6912
Answer:
60 days.
Step-by-step explanation:
This is a proportion question. You compare two ratios. Unfortunately it is an inverse ratio.
12 = k/100 Multiply both sides by 100
1200 = k
20 = k/x Multiply both sides by x
20x = k
20x = 1200 Divide by 20
20x/20 = 1200/20
x = 60 days.
An inverse proportion works by making a constant k. The constant k makes the days shorter when the number of people increases. You should expect that. More people , less time.
Your insight that the function values differ by 5 every time is very important. So your f(x) will contain 5x as a term. You have to find a constant to add or subtract to make sure f(1)=-2.
f(x) = 5x-7 does the job.
we know that
the speed's formula is equal to
in this problem we have
Substitute the values in the formula
therefore
<u>the answer is</u>
3,6,9,7
1/3 = 0.33333 forever
1/6 = 0.1666666666 forever
1/9 = 0.1111111 forever
1/7 = 0.1428----
