Answer:
should be after 10 years , $1967.15
Answer:


Step-by-step explanation:
Given
Represent volume with v, height with h and radius with r

Required
Determine the values of h and r that uses the least amount of material
Volume is calculated as:

Substitute 432π for V

Divide through by π

Make h the subject:

Surface Area (A) of a cylinder is calculated as thus:

Substitute
for h in 


Factorize:

To minimize, we have to differentiate both sides and set 

Set 

Divide through by 


Cross Multiply


Divide through by 2

Take cube roots of both sides
![r = \sqrt[3]{216}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B3%5D%7B216%7D)

Recall that:




Hence, the dimension that requires the least amount of material is when

Answer:
no solution
Step-by-step explanation:
49^3x = 343^2x+1
49 = 7^2 and 343 = 7^3
7^2 ^3x = 7^3 ^2x+1
we know that a^b^c = a^ (b*c)
7^(2 *3x) = 7^(3 *(2x+1))
7^(6x) = 7^(6x+3)
The bases are the same so the exponents have to be the same
6x = 6x+3
Subtract 6x from each side
0 =3
This is never true so there is no solution
A. all number greater than a will be to the RIGHT of a
b. all numbers less than a will be to the LEFT of a
