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)

Answer:

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

In parallelogram QRST QS RT Is QRST a rectangle ?
fomenos

Answer:

The correct option is A.

Step-by-step explanation:

It is given that the QRST is a parallelogram and the diagonals QS and RT are congruent.

According to the property of parallelogram if the length of diagonals are same, then the parallelogram is rectangle. We can also prove it.

Let QRST be an parallelogram and QS=RT.

In triangles QRT and RQS.

RT=QS         (Diagonals)

QR=QR         (Common side)

QT=RS         (Opposite sides of the parallelogram are same)

So by SSS rule of congruence, triangle QRT and triangle RQS are congruent.

By CPCT,

\angle R=\angle Q

Since the sum of two consecutive angles of a parallelogram is 180 degree.

\angle R+\angle Q=180

2\angle R=180

\angle R=90

Therefore the measure of angle R and angle Q are 90 degree.

Similarly in triangle QST and RTS,

RT=QS         (Diagonals)

ST=ST         (Common side)

QT=RS         (Opposite sides of the parallelogram are same)

So by SSS rule of congruence, triangle QST and RTS are congruent.

By CPCT,

\angle S=\angle T

Since the sum of two consecutive angles of a parallelogram is 180 degree.

Therefore the measure of angle S and angle T are 90 degree.

Since the measure of all interior angles of QRST are 90 degree, therefore the parallelogram QRST  is a rectangle.

Given the arithmetic sequence an = 4 − 3(n − 1), what is the domain for n? (6 points)
dedylja [7]
Given the arithmetic sequence is given by:
an=4-3(n-1)
writing the above into a straight line form we get:
an=4+3-3n
an=-3n+4
this a straight line equation with a negative slope, thus the domain will be:
(-∞,∞)
