Find the amount of time needed for the sinking fund to reach the given accumulated amount. (Round your answer to two decimal pla
tatiyna

Answer:

8.82 years.

Step-by-step explanation:

Since, the monthly payment formula is,

P=\frac{PV(r)}{1-(1+r)^{-n}}

Where, PV is the present value of the loan,

r is the rate per month,

n is number of months,

Here,

PV =  $ 25,000,

Annual rate = 5.2 % = 0.052 ⇒ Monthly rate, r = \frac{0.052}{12}

( 1 year = 12 months )

P = $ 295,

By substituting the values,

295=\frac{25000(\frac{0.052}{12})}{1-(1+\frac{0.052}{12})^{-n}}

By the graphing calculator,

We get,

n = 105.84

Hence, the time ( in years ) = \frac{105.84}{12}=8.82

Two of largest mammals on earth are the blue wale and the African elephant. An adult male blue whale weighs about 170 tonnes or
Liula [17]

Weight is 1.7 × 10^5 kg

Step-by-step explanation:

  • Step 1: Given that the weight of the blue whale = 170 tonnes
  • Step 2: Convert the number of tonnes into kg.

⇒ 170 tonnes = 170 × 1000 (1 tonne = 1000 kg)

⇒ 170 tonnes = 17 × 10^4 kg

  • Step 3: Convert it into standard format, that is with just one decimal point.

⇒ 17 × 10^4 = 1.7 × 10^5 kg (Dividing and multiplying by 10 on both sides)
