Start out with writing it
3.8 x 0.5+ 1.5 x 30
Multiply the numbers: 3.8 x 0.5 = 1.9
=1.9+30 x 1.5
Multiply the numbers: 1.5 x 30= 45
=1.9 +45
Add the numbers: 1.9 + 45=46.9
=46.9
Answer:
$16,000
Step-by-step explanation:
Revenue is the product of price and the number sold. Using the given relation for number sold, the revenue as a function of price is ...
R(p) = p(-40p +1600) = -40p(p -40)
This is the equation of a quadratic that opens downward and has zeros at p=0 and p=40. The vertex is halfway between those zeros, at p=20. The revenue at this price is ...
R(20) = -40·20(20 -40) = 16,000 . . . . dollars
Answer:

Step-by-step explanation:
Answer:
Look below
Step-by-step explanation:
1) x = 14, because 14 * 14 = 196
2) x = 3 / 16, because ( 3 / 16 ) * ( 3 / 16 ) = 9 / 256
3) x = 8, because 8 * 8 * 8 = 512
4) x = 4 / 7, because ( 4 / 7 ) * ( 4 / 7 ) * ( 4 / 7 ) = 64 / 343
