Answer:
8
Step-by-step explanation:
If the only zero for this function is at x = - 4 it looks like this:
f(x) = (x+4)(x+4) = x^2 +8x + 16 <u> so j = 8 </u>
area of circle =22/7×4=12.56
The compound inequality represents the situation is r > 4 and r ≤ 4.1
<h3>Compound inequality</h3><h3 />
- r must be greater than 4 cm
r > 4
r ≤ 4.1
Therefore, r > 4 and r ≤ 4.1 is the compound inequality which represent the situation.
