Abank has opened a new branch and, as part of a promotion, the bank branch is offering $1,000 certificates of deposit at simple interest of 4% per year. the bank is selling certificates with terms of 1, 2, 3, or 4 years. which of the following functions gives the total amount, aaa, in dollars, a customer will receive when a certificate with a term of kkk years is finally paid? a) a=1,000(1.04k)b) a=1,000(1+0.04k)c) a = 1,000(1.04)^kd) a = 1,000(1 + 0.04^k)

option A

Step-by-step explanation:

given,                                                

the bank branch is offering $1,000 certificates of deposit.

Rate of interest per year = 4 % = 0.04                        

The bank is selling certificates with terms of 1, 2, 3, or 4 years

total amount =  A , in dollar              

time of investment = k years              

4 k% is added to the original deposit.

A = P + P r t                                      

A = P (1 + r t)                                          

A = P (1 + 0.04 k)                            

the correct answer is option A

she will most likely have 33  

step-by-step explanation:

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1
