3.1,2,2/3,0.55,0, -7/8,-4
(5,9) because vertex form is (x-h)^2+k and the vertex is (h,k) so it would be (5,9)
Not sure, but I would rather not leave this question blank. Please refer to the picture to help
Answer:
$55
Step-by-step explanation:
Given data
Principal = $50
Rate= 10%
Time = 1 year
The simple interest formula is given as
A= P(1+rt)
substitute
A= 50(1+0.1*1)
A= 50(1.1)
A= $55
Hence the balance in her account will be $55
Answer:
Total amount that Matthew's bank will receive is $10099.81.
Step-by-step explanation:
We need to find the amount Matthew's bank will receive after lending him $8,000 for four years at an interest rate of 6 percent, compounded annually.
The formula for compound interest is:

Where A = future value
P= Principal Amount
r = interest rate
and n= time
So in the question we are given:
P= $8000
r = 6% or 0.06
t = 4 (since 4 yeras compounded annually)
A= 8000*(1+0.06)^4
A= 8000*(1.06)^4
A= 10099.81
So, total amount that Matthew's bank will receive is $10099.81.
