Answer:
1200 signatures are needed
Step-by-step explanation:
t = total number of signatures
t * 36% = 432
Change to decimal form
.36t = 432
Divide each side by .36
.36t/.36 = 432/.36
t =1200
1200 signatures are needed
Answer:
A. 
B. $2,307.69
Step-by-step explanation:
You are given the formula
where V = investment earning simple interest
p = principal,
r = interest rate
t = time
So,
A. 
B. r = 0.06 (or 6% as percent)
V = $3,000
t =5
so,
I have a sum because it is an addition problem
Answer:
18,300
Step-by-step explanation:
Answer: The polynomial
= y² - 5y - 4.
Step-by-step explanation:
Let the polynomial = f(y)
Therefore
y² -5y + 1 - f(y) = 5
f(y) = y² - 5y + 1 - 5
f(y) = y² - 5y - 4
The polynomial = y² - 5y - 4.
Check:
y² - 5y + 1 - ( y² - 5y - 4)
Open the bracket with the minus
y² - 5y + 1 - y² + 5y + 4
y² - y² - 5y + 5y + 1 + 4
= 0 - 0 + 5
= 5.
