Answer:
y = 20
Step-by-step explanation:
-3y+12 = -48 . -12 from both sides
-3y = -60 . ÷3 on both sides
y = 20
Solution :
Let be the unit vector in the direction parallel to the plane and let be the component of F in the direction of and be the component normal to .
Since,
Therefore,
From figure,
We know that the direction of is opposite of the direction of , so we have
The unit vector in the direction normal to the plane, has components :
Therefore,
From figure,
∴
Therefore,
If a bag of pumpkin seeds must weigh within 2.1 grams in order to be accepted, each bags must weigh between (400-2.1) grams and (400+2.1) grams. This means that if a bag weighs less than 397.9 grams (x<397.9) or more than 402.1 grams (x>402.1) it will be rejected. Therefore, 397.9>x>402.1 is the range of rejected bags.
