Answer:
the position of a particle moving at a coordinate say(y) will satisfy the given conditions t=0 (say) if y=2sint-cost
Step-by-step explanation:
Clearly by the above we can see that if y=2sint-cost at t=0, then y=-1 because at t=0 sint vanishes and leaves us with only cost and at t=0 cos0=1
If you decrease a price by 20% you multiply the original cost by 0.8
So, if y times 0.8 = $12, then you do y=12/0.8 which is 15.
The original cost is $15.
Answer:
expression:3(1/2)+1 ; 2 1/2
Step-by-step explanation:
Combine 3 and 1/2
3+1/2
=5/2
Simplify the expression.
=5/2
=2
Answer:
D. 30 - 6n + 3 × 8 for n = 3.5
Step-by-step explanation:
Replace n by given value
30 - 6×(3.5) + 3 × 8 (Do the multiplying first then add and subtract)
➡
30 - 21 + 24 = 33
