F(x)=x2,
g(x)=f(3x)=(3x)2=9x2
Now to graph y=9x2. This is a parabola (U-shape), vertex at (0, 0), symmetric aroung y axis. When x=1/3 or -1/3, then y=1.
So, try to draw the graph.
Answer:
0.375
Step-by-step explanation:
Same height when both equations are equal
-16x^2 + 74x + 9 = -16x^2 + 82x
82x - 74x = 9
8x = 9
x = 9/8
x = 1.125
x = 1.13 ---->rounded to nearest hundredths of seconds
answer
1.13 seconds
Answer:
D. 8.8
Step-by-step explanation:
As the pythagorean theorem.
A² + B² = C²,
5.4 × 5.4 + 7 × 7 = C²,
29.16 + 49 = C²,
78.16 = C²,
8.8 ≈ C
