Answer:
(a) 8.15
(b) 12.92
Step-by-step explanation:
Given: P = $3000, r = 0.085

Where
A is the Amount
P is the Principal
r is the rate
t is the time
(a) For the amount to double, A = 2 × P
A = 2 × $3000
A = $6000



Take
of both sides

But 
∴ 


t = 8.15
(b) For the amount to double, A = 3 × P
A = 3 × $3000
A = $9000



Take
of both sides

But 
∴ 


t = 12.92

Answer:
About $0.10 per ounce
Step-by-step explanation:
12 pound costs $18.75. Lets find the cost per pound first:
Cost Per Pound = 
We know, there are 16 ounces in 1 pound.
We know 1 pound costs 1.5625
To find cost per ounce, we have to divide this by 16.
So,
Cost Per Ounce = 
Rounded to nearest cent, that would be 10 cents per ounce
SOLUTION

The degree of the polynomial
CONCEPT TO BE IMPLEMENTED
POLYNOMIAL
Polynomial is a mathematical expression consisting of variables, constants that can be combined using mathematical operations addition, subtraction, multiplication and whole number exponentiation of variables
DEGREE OF A POLYNOMIAL
Degree of a polynomial is defined as the highest power of its variable that appears with nonzero coefficient
When a polynomial has more than one variable, we need to find the degree by adding the exponents of each variable in each term.
EVALUATION
Here the given polynomial is
In the above polynomial variable is z
The highest power of its variable ( z ) that appears with nonzero coefficient is 5
Hence the degree of the polynomial is 5
FINAL ANSWER
The degree of the polynomial is 5
