Answer:
Step-by-step explanation:
t - 1 - t^3 - 4t
-t^3 - 3t
The product of 100 x a number would be 10 times larger than the product of 11 x a number
Answer:
the answer is C
Step-by-step explanation:
the equation is y=mx+b
the b is the starting point which is 25
the m is the slope/rate of change which is 5
as a result Y =5x+25
Answer:
270
Step-by-step explanation:
For any arithmetic sequence
nth term is given by
nth term = a + (n-1)d
where a is first term,
d is common difference
d is given by nth term - (n-1)th term
sum of n terms given by
sum = n/2(2a + (n-1)d)
________________________________________________
Given arithmetic sequence
-2,0,2,4,6,8...
first term a = -2
lets take third term as nth term and second term as (n-1)th term to find common difference d.
d = 2 - 0 = 2
using a = -2 , d = 2, n = 18
thus, sum of first 18 terms = n/2(2a + (n-1)d)
=18/2( 2*(-2) + (18-1) 2)
=9 ( -4 + 34)
=9 ( 30) = 270
Thus, sum of first 18 terms is 270.
