Answer:
0.25s
Step-by-step explanation:
As v = 1.5 cos(4πt), v is maximum when cos(4πt) is maximum = 1. So the maximum velocity would be 1.5 m/s
Both the lowest and highest position occurs when its derivative is 0, aka v = 0 and has a change of direction
1.5 cos(4πt) = 0
cos(4πt) = 0
4πt = π/2 and 4πt = 3π/2
t = 1/8 = 0.125s and t = 3/8 = 0.375s
So the time it takes to travels from 1 point of time (0.125s) to another point of time (0.375) is
1) This probability is given by
... C(40,5)·0.12⁵·0.88³⁵ ≈ 0.18665 . . . . . where C(n, k) = n!/(k!(n-k)!)
2) This probability is given by
... 0.88⁴⁰ ≈ 0.00602
3) This is the complement of the probability that all have failed.
... 1 - 0.12⁴⁰ ≈ 1.0000

Answer:
3) 16π cm²
4) 240.625 cm²
Step-by-step explanation:
<em>3. For this problem I'm going to use the formula Area = π × r²</em>
<em>To start off, I'm going to input our value of radius which is 4cm.</em>
π × 4²
<em>Finally, I'm going to square our value "4"</em>
16π cm²
<em>(I'm going to "leave my answer in terms of π" as the problem states but if you need the complete answer it would be </em>about 50.24 cm²
<em>4. For this problem I'm going to use the formula Area = π × (d/2)²</em>
<em>To begin, I will divide our diameter by 2 to find the radius.</em>
17.5/2 = 8.75
<em>Next, we are going to square our now, radius.</em>
8.75² = 76.5625
<em>Now, we have to multiply our squared radius by π (in this problem it states to use 22/7, so that's what we'll do :)</em>
76.5625 × 22/7 = 240.625 cm²
<em>So! This is our final answer!</em>
