Answer:
A
Step-by-step explanation:
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
Answer:
True
Step-by-step explanation:
minus into minus = plus
Step-by-step explanation:
linear function
y = ax + b
f(-4) = -4
x = -4
y = -4
-4 = a×-4 + b
f(4) = -1
x = 4
y = -1
-1 = 4a + b
sum both equations
-5 = 0 + 2b
b = -5/2
-1 = 4a - 5/2
3/2 = 4a
a = 3/2 / 4 = 3/8
the function would be
y = 3/8 x - 5/2
OP = 4 because its a radius of the smaller circle which has a radius of 4 and all radii of the same circle are the same length.
C) 4
