Find −3a^2 − b^3 + 3c^2 − 2b^3 if a = 2, b = −1, and c = 3. *
1 answer:
Substitute the values in the expression:-
= -3*2^2 - (-1)^3 + 3*3^2 - 2*(-1)^3
= -12 - (-1) + 27 - 2*-1
= -12 + 1 + 27 + 2
= 18 (answer)

A kilogram is worth 1000 g.
5kg = 5000 grams.
So 5212 grams is bigger.
cosU:-
As U lies in Q3
sinV
As V lies in Q3
So
- sin(V-U)=sinVcosU-cosVsinU=(-3/5)(-24/25)-(-4/5)(-7/25)=72/125-28/125=72-28/125=<u>4</u><u>4</u><u>/</u><u>1</u><u>2</u><u>5</u>
- cos(U-V)=cosUcosV+sinUsinV=(-24/25)(-4/5)+(-7/25)(-3/5)=96/125+21/125=117/125
