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

suppose that a severe virus in impacting a bee colony and the population of bees has a half life of 5 days What percentage of th
BartSMP [9]
So we want to know what percentage of bees would survive a virus after 19 days of decay if the bee population has a half life of 5 days. So every 5 days 50% of bees die. Lets say that N is the number of bees before the virus. So after 5 days is 50% less bees, so 50% of N remains. After another 5 days again, 50% bees die, and 50% out of 50% is 25%. So after 10 days, 25% of bees remain or 25%N or 0.25*N. After another 5 days its 12.5 % of bees remain or 0.125*N. And after 4 days 40% more bees die. And that is 0.4*0.125*N = 0.05N. 0.05*100% is 5%. So after 19 days, 5% of bees remain and 95% of bees is dead.

Two numbers are in a ratio of 1:4 and their sum is 50. What is the smaller number?
katrin [286]
Let us assume the common ratio to be = x
Then
(1 * x) + (4 * x) = 50
x + 4x = 50
5x = 50
x = 50/5
   = 10
So from the above deduction, we get the common ratio to be equal to 10
Then
The smallest number = 1 * x
                                  = 1 * 10
                                  = 10
