Find the amount of interest on $1,500 invested for 20 days at 6.75%, compounded daily. $_____
LekaFEV [45]

Answer:

The required amount of interest is $5538.  

Step-by-step explanation:

Given : $1,500 invested for 20 days at 6.75%, compounded daily.

To find : The amount of interest ?

Solution :

Applying compound interest formula,

A=P(1+r)^t

Where, A is the amount

P is the principal P=$1500

r is the interest rate  r=6.75%=0.0675 compounded daily

t is the time t=20 days

Substitute the value in the formula,

A=P(1+r)^t

A=1500(1+0.0675)^{20}

A=1500(1.0675)^{20}

A=1500\times 3.69

A=\$5538

Therefore, The required amount of interest is $5538.

Which is the more reasonable measurement of the distance between the tracks on a DVD: 7.4 ⋅ 10−4 mm or 7.4 ⋅ 104 mm? Justify you
EleoNora [17]

Answer:

A- 7.4 ⋅ 10−4 mm

Step-by-step explanation:

Well, to solve this problem, we must convert the number and / or the units in a more imaginable one.

We are given two choices:

a. 7.4 x 10^-4 mm

b. 7.4 x 10^4 mm

Converting the units and numbers into meters and general form, respectively. (What is meant by general form is not to write it in scientific notation).

a. 7.4 x 10^-4 mm (1 m / 1000 mm) = 0.00000074 m

b. 7.4 x 10^4 mm (1 m / 1000 mm) = 74 m

Now comparing the two values above, what do you think is the distance between the tracks on a DVD? Definitely NOT 74 m or else the DVD is extremely big. Therefore the correct is the smaller one.
