 If 2x3 – 4x2 + kx + 10 is divided by (x + 2), the remainder is 4. Find the value of k using remainder theorem. Please help :)​
Vinvika [58]

The polynomial remainder theorem states that the remainder of the division of a polynomial P(x) by x-a is equal to P(a).

Therefore

P(-2)=4\\2\cdot(-2)^3 - 4\cdot(-2)^2 + k\cdot(-2) + 10=4\\-16-16-2k=-6\\-2k=26\\k=-13

What is the 100th term of the sequence 7, 4, 1, -2 ...
pentagon [3]
The sequence is arithmetic as it goes down 3 every time

Arithmetic nth term formula is an=a1+d(n-1)

an=7-3(n-1)
an=7-3n+3
an=-3n+10

To find the 100th term substitute n for 100
a100=-3(100)+10
a100=-300+10
a100=-290

The 100th term is -290
