The area of a square is decreasing at a rate of 43 square inches per second. At the time when the side length of the square is 7
Sergio039 [100]

Answer:

26.230 Inches per second.

Step-by-step explanation:

Since, Area of square is decreasing at the rate of 43 square inches per second And area is directly proportional to square of the side , So

Its side will be decreasing at the rate of \sqrt{43} inches per second .

Now,

Perimeter of square is directly proportional to 4 times of the side of the square.

so Perimeter of square will be decreasing at the rate of 4× \sqrt{43}

After rounding off to three decimal places we will get 26.230 Inches per second.

Amanda just took out a loan for $950 at a 7.2% APR, compounded monthly, to
vaieri [72.5K]

Answer:

C. 16 months faster

Step-by-step explanation:

You can solve this using a Financial calculator( TI BA II plus in this case)

First, find number of months if recurring monthly payment is $38.50;

Amount borrowed ; PV = -950

Monthly rate ; I/Y  = 7.2%/12 = 0.6%

Monthly payment; PMT = 38.50

Future value ; FV = 0

Total duration;  press CPT, N = 26.785  OR 27 months

Next, find number of months if recurring monthly payment is $93;

Amount borrowed ; PV = -950

Monthly rate ; I/Y  = 7.2%/12 = 0.6%

Monthly payment; PMT = 93

Future value ; FV = 0

Total duration;  press CPT, N = 10.573 OR 11 months

Difference = 27 -11 = 16

Therefore, she would be able to pay off the loan 16 months faster.

Tom wishes to purchase a property that has been valued at $300,000. He has $30,000 available as a deposit, and will require a mo
Mekhanik [1.2K]

Answer: The total interest paid on the mortgage is $179550

Step-by-step explanation:

The initial cost of the property is $300000. If he deposits $30000, the remaining amount would be

300000 - 30000 = $270000

Since the remaining amount was compounded, we would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 270000

r = 2% = 2/100 = 0.02

n = 12 because it was compounded 12 times in a year.

t = 25 years

Therefore,

A = 270000(1+0.02/12)^12 × 25

A = 270000(1+0.0017)^300

A = 270000(1.0017)^300

A = $449550

The total interest paid on the mortgage is

449550 - 270000 = $179550

Is (3,-2) a solution to the system below? How do you know?
cricket20 [7]

Step-by-step explanation:

you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.

if yes, it was a solution, and if just only one is false, then it was not a solution.

(3, -2) in

y + 4x = 10

5x - y = 13

so,

-2 + 4×3 = 10

-2 + 12 = 10

10 = 10 true

5×3 - (-2) = 13

15 + 2 = 13

17 = 13 false

so, it was NOT a solution.
