What is the real interest rate if the nominal interest rate is 1 when the rate of inflation is 2
vovikov84 [41]

Answer:

Real interest rate = -1%

Step-by-step explanation:

Real interest rate=Nominal interest rate - inflation rate

From the above,

Nominal interest rate=1%

Inflation rate=2%

Real interest rate=Nominal interest rate - inflation rate

=1% - 2%

= -1%

Real interest rate = -1%

Real interest rate shows you what it really costs borrowers to pay back their loans.

if the real interest rate is greater than zero, the amount you pay back is worth more in real terms than the money you borrowed.

if the real interest rate is below zero as in the above case, the amount you will pay back is less worth in real terms than the money you borrowed.

What is the radius of a circle given by equation x^2 + y^2 - 2x + 8y - 47 = 0
Lera25 [3.4K]
X^2 + y^2 - 2x + 8y - 47 = 0
x^2 + y^2 - 2x + 8y = 47
(x^2 - 2x) + (y^2 + 8y) = 47
(x^2 - 2(1)x) + (y^2 + 2(4)y) = 47
(x^2 - 2(1)x + 1^2) + (y^2 + 2(4)y + 4^2) = 47 + 1^2 + 4^2
(x - 1)^2 + (y + 4)^2 = 64 = 8^2

I need help please now
Talja [164]

Answer:

  8x +5y

Step-by-step explanation:

As with any purchase, the extended amount of the bill for an item is the product of the number of items bought and the price of each of them. The total bill is the sum of the extended amounts.

On Samuel's first visit he paid ...

  3x +2y . . . . . dollars for apples and spinach

On Samuel's second visit, he paid ...

  5x + 3y . . . . . dollars for apples and spinach

Then the total he spent was ...

  (3x +2y) +(5x +3y) = (3x +5x) +(2y +3y) = 8x +5y
