Answer:

Step-by-step explanation:

8b^2 +2a(4c-b)

Let a = 1/4 b=2 c= -3

8 ( 2)^2 +2(1/4) ( 4*-3 -2)

Parentheses first

8 ( 2)^2 +2(1/4) ( -12 -2)

8 ( 2)^2 +2(1/4) ( -14)

Then exponents

8 ( 4) +2(1/4) ( -14)

Then multiply

32 -7

Subtract

A reacher deposited Rs 66000 in his/her saving account for as many years as the rate of interest per annum .If he/ she received

natali 33 [55]

Answer:

Time and rate is 4 years and 4% respectively.

Step-by-step explanation:

P = Rs 66000

T = R

I = 10560

I = PTR/100

Rs 10560 = (66000*T^2)/100

or, Rs 1056000 = 66000*T^2

or. 1056000/66000 = T^2

or, 16 = T^2

OR, T =√16

so T = 4

Then

T = R

so, R = 4

milton opens a store credit card when he purchases appliances for his kitchen. the interest rate is 17.45%. he charges $3,740 to

kari74 [83]

Answer-

The total cost of his purchase will be $3,846.34

Solution-

Here, the annual interest rate is 17.45%.

So monthly interest rate will be,

$=\frac{17.45}{12} =1.454\%=0.01454$

With a purchase of $3,740, the amount will be after one month,

$=3740(1+0.01454)^1=3740(1.01454)=3794.38$

Then she makes a payment of $1350, so the balance at the end of month 1 is

$=3794.38-1350=2444.37$

Now she has to pay with $2444.37 as principal amount, the amount will be after one month,

$=2444.37(1+0.01454)^1=2444.37(1.01454)=2479.91$

Then she again makes a payment of $1350, so the balance at the end of month 2 is

$=2479.91-1350=1129.91$

Final month, she has to pay with $1129.91 as principal amount, the amount will be,

$=1129.91(1+0.01454)^1=1129.91(1.01454)=1146.34$

So the total cost, including interest, would be the sum of the three payments,

$=1350+1350+1146.34=3,846.34$
