Answer:
S= 4000n+50000
Step-by-step explanation: Table
50000+4000=54000 0 5000
54000+4000=58000 1 54000
58000+4000=62000 etc.. 2 58000
3 62000
Is increasing by 4000 and thats the rate of change so S=4000n
And the y intercept always will be with a 0 in the cordinates and the only with a 0 is 50000.
We put all together and it will be
Answer: S=4000n+50000
Answer:

Step-by-step explanation:
Since the height isn't given, we assume it to be "h" (of cylinders). And the answer will be in terms of "r" and "h".
The area of 1 arm is given, so the area of 2 arms would be:

Now, area of 2 cylinders would be the formula:

So, total area is A_arm PLUS A_cyl. The fractional area the arms are would be gotten by taking expression A_arm divided by A_total.
Shown below:

We simplify further:

THis is the answer.
Set up a proportion. 6/10 = 9/x. cross multiply so x times 6 = 6x. And 10 times 9 = 90. so 6x=90. Then 90 and 6x divided by 6. which gets you x=15. The 9 ft tall elephant will cast a 15 ft shadow.
