Deposits of $200 per month are put into an investment plan that pays an APR of 6.5%. How much money will be in the plan after

Cerrena [4.2K]

Answer:

The money will be $7455.97.

Step-by-step explanation:

Given : Deposits of $200 per month are put into an investment plan that pays an APR of 6.5%.

To find : How much money will be in the plan after 18 years ?

Solution :

There is a deposit of $200 per month.

For 1 year the principle value is $P=200\times 12=2400$

The rate of interest is r=6.5%=0.065

The time is t=18 years

Apply compound interest formula,

$A=P(1+r)^t$

$A=2400(1+0.065)^{18}$

$A=2400(1.065)^{18}$

$A=2400\times 3.1066$

$A=7455.97$

Therefore, The money will be $7455.97.

The dimensions of a closed rectangular box are measured as 60 centimeters, 50 centimeters, and 70 centimeters, with an error in

Studentka2010 [4]

Answer:

The maximum error in calculating the surface area of the box is 72 square centimeters.

Step-by-step explanation:

From Geometry, the surface area of the closed rectangular box ( $A_{s}$ ), in square centimeters, is represented by the following formula:

$A_{s} = w\cdot l + (w + l)\cdot h$ (1)

Where:

$w$ - Width, in centimeters.

$l$ - Length, in centimeters.

$h$ - Height, in centimeters.

And the maximum error in calculating the surface area ( $\Delta A_{s}$ ), in square centimeters, is determined by the concept of total differentials, used in Multivariate Calculus:

$\Delta A_{s} = \left(l+h\right)\cdot \Delta w + \left(w+h\right)\cdot \Delta l + (w+l)\cdot \Delta h$ (2)

Where:

$\Delta w$ - Measurement error in width, in centimeters.

$\Delta l$ - Measurement error in length, in centimeters.

$\Delta h$ - Measurement error in height, in centimeters.

If we know that $\Delta w = \Delta h = \Delta l = 0.2\,cm$ , $w = 60\,cm$ , $l = 50\,cm$ and $h = 70\,cm$ , then the maximum error in calculating the surface area is:
