Answer:
160 cm²
Step-by-step explanation:
V = 1/3 * 24 * 20 = 160 cm²
2.8 m = .0028 km
3.5/.0028 = 1259 revolutions
The answer is <span>252.5 ft
</span><span>y = –0.004x</span>²<span> + x + 2.5
Let's take y = 0 and we'll get the quadratic equation:
</span>–0.004x² + x + 2.5 = 0
The general formula for quadratic equation is:
ax² + bx + c = 0
a = -0.004
b = 1
c = 2.5


Since distance cannot be negative (x1), the correct answer is x2 = 252.5 ft
