Answer:
Step-by-step explanation:
Factorise the denominator of the second fraction
y² - 1 = (y - 1)(y + 1) ← difference of squares
To obtain a common denominator
multiply numerator/ denominator of first fraction by (y + 1)
= 
- 
← subtract numerators leaving the common denominator
= 
= 
= 
← cancel common factor (y - 1) on numerator/denominator
=
From the prime factorization of 49, we get 7*7. From 196, we get <span>2*2*7*7. From 343, we get 7*7*7. The greatest "overlap" or common factors are 7*7, or 49.</span>
Thus, the greatest common factor is 49.
When the polynomial has more than one variable you have to sum the exponents of the variables for every monomial. The largest sum is the order of the polynomial.
Here:
momomial sum of the exponents
8x^3y^2 3 + 2 = 5
-10xy 1 + 1 = 2
4x^2y^2 2 + 2 = 4
Then the degree is 5.
Answer:
C. 2.3 repeated
Step-by-step explanation:
1/3 doesn't equal a (what you could say is) regular decimal. It repeats because it does not evenly go into 10 or 100
Given :
The population of fish in a pond from 2001 to 2014 is modeled by the function below where t is the years since 2001.
...1)
To Find :
Find the number of fish is the pond in 2014.
Solution :
Number of years, t = 2014 - 2001 = 13.
Putting value of t in equation 1), we get :
p(t) ≈ 486
Therefore, number of fish in the pond in 2014 is 486.
Hence, this is the required solution.
