The function that is a tangent to the graph of f is 
<h3>What is the concept of integral?</h3>
The definite integral can be interpreted as the resulting area of a region. In addition, it is a value in its result, that is, it does not depend on the variable x, which can be exchanged for any other variable without changing the value of the integral.
Knowing that :
- 40x + y = 0 is tangent of f(x)
- slope of the line = -40
therefore, f'(x)|x=a = -40, so only look for a we have:

if, x = -2, then y = 80 (since, 40x + y = 0), therefore, f(x) passes through (-2,80), so in the equation:

Therefore,

Area= base x altura dividido entre 2
So this is direct proportional question
so y=(k)x
sub y=48 and x=6
48=6k
k=8
now you got a constant k
now sub x=3
y=(8)(3)
=24
X(x+2)=224x2+2x-224=0(x+16)(x-14) =0x= 16 or 14
the answer is 16 and 14
Answer:
Account Receivable Days : 14.16 days
Fixed Asset Turnover : 0.48 times
Total Asset Turnover : 0.27 times
Inventory Turnover : 3.98 times
Step-by-step explanation:
1) Account Receivable days is calculated as : (Account Receivable/Revenue) * Number of days in a year. Hence the answer is calculated as = (52000/134
0000) * 365 = 14.16.
2) Fixed Assets Turnover is calculated as : Net Sales/Fixed Assets. Hence the answer is calculated as 1340000/2790000 = 0.48.
3) Total Asset turnover is calculated as : Nets Sales/Total Assets. Hence the answer is = 1340000/4990000 = 0.28.
4) Inventory Turnover is calculated as : COGS/Average Inventory. Hence the answer is = 601000/151000 = 3.98.
