Answer:
y= −9.16x²+73.04x+183.3
Values increase till x = 4 and then decrease which means thus curve has a maximum turning point around 4.
Coefficient of x² should be negative
because max to (concave down)
x = -b/2a should be around 4
x = -73.04/(2×-9.16) = 3.987
Given:
Amount borrowed (P)= $25000
Rate of interest (r)= 6%
Time (t)= 4 years.
To find:
The total interest the company pay in all.
Solution:
We know that,

where, A is amount, P is principal, r is rate of interest and t is time period.




Now,



Therefore, the total interest is $6561.924.
The multiplicative of 6 is 1/6
This is what I get not sure if the problem on numerator is together if it is then . X^2+(a^2+1) x^2+a^2+1.
-----------------= ----------------- AX+1. Ax+1 Answer: a^2+x^2+1 ---------------- AX+1
If I wrote the actual problem wrong let me know. This is what I understood.
