Mathematics
1 answer:

Answer:

1/3(4√2/2- 5)

-1/3(4√2/2 + 5)

Step-by-step explanation:

2(3x+5)² -16=0

2(3x+5)²=16

(3x+5)² = 4²/2

3x+5= 4/√2 ⇒ 3x= 4/√2- 5 ⇒ x= 1/3(4√2/2- 5)

3x+5= -4√2 ⇒ x= -1/3(4√2/2 + 5)

Ian has the option of purchasing or renting a home. The purchase option requires a loan of $100,000 for a 20-year term at a 4.9%
jenyasd209 [6]

Answer:

The correct answer to the following question will be "70.56".

Step-by-step explanation:

The given values are:

Loan requires, PV = $100,000

Years = 20

Number of months, n = 240

Rate interest = 4.90000%

Monthly rate, r = 0.408333%

Monthly rental payment = $725

As we know,

PV=PMT\times (\frac{1}{r})\times [1-[\frac{1}{(1+r)^n}]]

On putting the values in the above formula, we get

⇒  100000=PMT\times (\frac{1}{0.004083333})\times [1-(\frac{1}{(1+0.004083333^{240})})]

⇒  100000=PMT\times 152.8014557

⇒  PMT=\frac{100000}{152.8014557}

⇒  PMT=654.44

Now,

Saving \ Per \ Month =Rent \ per \ month-PMT

On putting the values, we get

⇒                             =725-654.44

⇒                             =70.56

Please solve this literal equation for the variable "f"
Tatiana [17]
\frac{df+10}{6}= g

Now, multiply both sides by 6 and you get.....

 df+10=6g

now, subtract 10 on both sides and you get.....

df=6g-10

now divide both sides by d to get f by itself and you get........

f= \frac{6g-10}{d}

How many hours a week do you have to work to make $5000 a month?
nasty-shy [4]
It depends on how much you earn in an hour .. so for example if your earn 100$ in 1 hour so you need to work for 50 hours in total because 5000 divided the amount of money you make in a single hour which is 100 in this example will be 50 hours in total .. to get the amount of hours you need to work a week you should know that the month has 4 weeks .. so 50 divided 4 equals 12.5 hours
