He got a discount of 32%, and saved 64$,
let the total amount without discount be x
according to the formula
32$=64×100/x
x=64×100/32
x=200$
E^(xy) = 2
(xdy/dx + y)e^(xy) = 0
At point (1, ln2), dy/dx + ln2 = 0
dy/dx = -ln2
Answer: 11.4
Simply multiply 38 by .30 to find the percentage of the number.
The fish is 2.25 ft above the water surface.
Step-by-step explanation:
- Step 1: Given expression for height of the fish above the water surface, y = -16x² + 12x where x is time in seconds. Find height after 0.375 seconds
⇒ y = -16(0.375)² + 12 × 0.375
= -2.25 + 4.5
= 2.25 ft
