I've seen this logic puzzle before. You're counting the number of circles in each digit. Each 9 has one circle, each 8 has two, etc. 1919 has two circles, so 1919 = 2.
D. You use explicit form if you have to multiply each term by a constant to get the next term, and use recursive form if you have to add a constant to each term to get the next term.
Answer:
-15
Step-by-step explanation:
Given is a polynomial in x
We have to find the remainder when the above polynomial is divided by x+5
Remainder theorem says that f(x) gives remainder R when divided by polynomial x-a means f(a) = R
Applying the above theorem we can say that value of the function when x =-5
= Remainder when f is divided by x+5
= F(-5)
Substitute the value of -5 in place of x
= (-5)^4 + 12(-5)^3 + 30(-5)^2 - 12(-5) + 70
= 625-1500+750+60+70
= 5
Hence answer is 5
