1 answer:

8 0

(x − 8)(y − 4) = 50, so y = 4 + 50 x−8 . Then A(x) = x 4 + 50 x − 8
x > 8. A 0 (x) = 4 − 400 (x − 8)2 , so A 0 (x) = 0 gives x = 18.
A 00(x) = 800 (x − 8)3 > 0
so the function is concave up, so x = 18 is the absolute minimum. When x = 18, y = 9.

The evaluation of ...

13 -2·3 +4/4 +4

starts with the multiplication, because there are no exponents or parentheses.

We have assumed your x is not a variable, but is intended to indicate multiplication. We have also assumed that your "divided by" implies no particular grouping, so that the numerator is the first preceding number and only the first following number is in the denominator.

At the end of year 1, Boller Co. had an ending balance in allowance for uncollectible accounts of $30,000. During year 2, Boller

Masja [62]

Answer:

$34,000

Step-by-step explanation:

First they had 30,000

Then wrote off 40,000

So balance is 30,000 - 40,000 = -10,000

Now, they want 8% of 300,000 as uncollectible. So that would be

0.08 * 300,000 = 24,000

Thus, to bring the balance to 24,000 [balance is -10,000], how much would they need to add?? Let it be x:

-10,000 + x = 24,000

x = 24,000 + 10,000 = $34,000

a roller coaster can take 24 riders in a single trip. 72 people went through the line to ride the roller coaster. how many trips

bulgar [2K]

Answer:

3 trips

Step-by-step explanation:

We would divide the amount of riders the roller coaster could take in a single trip by the total number of riders to determine how many trips it can make.

max amount of riders/total riders

72/24 = 3

Hence, the rollercoaster made 3 trips.
