What is the total investment of $2150 invested at 5.3% for 16 years and compounded continuously?
sladkih [1.3K]

Answer:

The total investment is $5020.19

Step-by-step explanation:

Given : $2150 invested at 5.3% for 16 years and compounded continuously

To find : What is the total investment?

Solution :

The formula of continuously compounded interest is

A = Pe^{rt}

Where A = amount invested

P = principal = $2150

e = Euler's number (on calculator)

r = interest rate as decimal = 5.3%=0.053

t = time in years = 16 years

Substitute the value in the formula,

A = Pe^{rt}

A = 2150\times e^{0.053\times 16}

A = 2150\times e^{0.848}

A = 2150\times 2.3349

A = 5020.19

Therefore, Option 4 is correct.

The total investment is $5020.19.

Evaluate the function f(x) = 2x2 - 6x + 3 for x = -1.
nadya68 [22]

Answer:

f(-1) = 11

Step-by-step explanation:

f(x) = 2x^2 - 6x + 3

Let x = -1

f(-1) = 2(-1)^2 -6(-1) +3

      =2*1 +6 +3

       =2+6+3

     = 11

The values (9.4,11) and (11,y) are from an inverse variation. Find the missing value and round to the nearest hundredth.
marusya05 [52]

Answer: 9.4

Step-by-step explanation:

Here the x-coordinates and y-coordinates have the inverse relation.

⇒ x\propto\frac{1}{y}

⇒ x=\frac{k}{y}

Where k is variation constant.

Since, point (9.4, 11) is from the inverse variation,

Therefore, this point must be satisfy the above condition,

That is,    9.4=\frac{k}{11}

k=103.4

Thus, the relation between the coordinates is,

x=\frac{103.4}{y}

Put x = 11, in the above function,

11=\frac{103.4}{y}

y=\frac{103.4}{11}=9.4
