How do you factorise 9 minus y squared?
1st of all, if you mean 9-y2 its simply a difference between two squares formula (3-y) (3+y)
7 11 19 35 what is the next number?
Difference between the terms: 1st & 2nd = 4 2nd & 3rd = 8 3rd & 4th = 16 4th & 5th = ?? The pattern of the differences can be seen as to be multiplying by two as the series progresses. It can be predicted that the next difference will be 16*2 = 32. Therefore, the next number will be 35 + 32 = 67.
In AP if the 6th and 13th terms are 35 and70 respectively find the sum of its first 20 terms?
To find the sum of the first 20 terms of an arithmetic progression (AP), we need to first determine the common difference (d) between the terms. Given that the 6th term is 35 and the 13th term is 70, we can calculate d by subtracting the 6th term from the 13th term and dividing by the number of terms between them: (70 - 35) / (13 - 6) = 5. The formula to find the sum of the first n terms of an AP is Sn = n/2 [2a + (n-1)d], where a is the first term. Plugging in the values for a (the 1st term), d (common difference), and n (20 terms), we can calculate the sum of the first 20 terms.
Why is 2 to the first power 1?
Any number to the 1st power is the same number, unchanged. Two to the 1st power is 2.
What is 7 to the negative 1st power?
7-1 equals 0.14285714285
