Which algebraic expression is a polynomial? 3m2n-2m/n+1/n
Lesechka [4]

Answer:

d) 7mn+\frac{3m}{2}+\frac{5n}{4}

Step-by-step explanation:

Which algebraic expression is a polynomial?

a)3m^2n-\frac{2m}{n}+\frac{1}{n}  \\b)\frac{2mn}{5}-\frac{\sqrt{m} }{4} +4m^5\\c)\frac{4m^3}{n^2}-3mn^5+\sqrt{8}\\d)7mn+\frac{3m}{2}+\frac{5n}{4}

Answer: A polynomial is an expression with variables and coefficients separated by addition and subtraction. The following are used when determining if an expression is a polynomial:

i) Variables of a polynomial must not have negative exponent.

ii) Variables of a polynomial must not have fractional exponent.

iii) Dividing by an exponent is not allowed

iv) Exponent radicals are not allowed.

a) 3m^2n-\frac{2m}{n}+\frac{1}{n} is not a polynomial because dividing by an exponent is not allowed.

b) \frac{2mn}{5}-\frac{\sqrt{m} }{4} +4m^5, is not a polynomial because exponent radicals are not allowed (√m)

c) \frac{4m^3}{n^2}-3mn^5+\sqrt{8} is not a polynomial because dividing by an exponent is not allowed.

d) 7mn+\frac{3m}{2}+\frac{5n}{4} is a polynomial

Charlie cannot remember how much he financed to buy his car. He does remember that his monthly payment is $200. His add-on inter
Mazyrski [523]
First find the total payments
Total paid
200×30=6,000 (this is the future value)

Second use the formula of the future value of annuity ordinary to find the monthly payment.
The formula is
Fv=pmt [(1+r/k)^(n)-1)÷(r/k)]
We need to solve for pmt
PMT=Fv÷[(1+r/k)^(n)-1)÷(r/k)]
PMT monthly payment?
Fv future value 6000
R interest rate 0.09
K compounded monthly 12
N=kt=12×(30months/12months)=30
PMT=6000÷(((1+0.09÷12)^(30)
−1)÷(0.09÷12))
=179.09 (this is the monthly payment)

Now use the formula of the present value of annuity ordinary to find the amount of his loan.
The formula is
Pv=pmt [(1-(1+r/k)^(-n))÷(r/k)]
Pv present value or the amount of his loan?
PMT monthly payment 179.09
R interest rate 0.09
N 30
K compounded monthly 12
Pv=179.09×((1−(1+0.09÷12)^(
−30))÷(0.09÷12))
=4,795.15

The answer is 4795.15

A barrel was 2/3 full of water. After 60 liters were used from the barrel, it was 5/12 full. how much water does the barrel hold
Andrews [41]

Answer: 240 liters

Step-by-step explanation: This means, we start off with (2/3)x liters of water. Then we subtract off 60 of them to get to 5/12 full, meaning we have (5/12)x liters left.
