Dude, it's easy!
t = d/s
t = 375/500
Now do the math! Get up your lazy butt to get ur phone or a calculator! Wasting your time typing this question when you can do it yourself, the nerve of some people!
BTW why is there a chinese character in your problem? This ain't Mandarin!
You're Welcome :)
Answer:0.63
0.97
Step-by-step explanation:
Given
Probability to detect the flaw by first inspector is 0.9
Probability to detect the flaw by second inspector is 0.7
(a)Probability that both inspector find the flaw
![P=0.9\times 0.7=0.63](https://tex.z-dn.net/?f=P%3D0.9%5Ctimes%200.7%3D0.63)
(b)Probability of finding flaw by at least one inspector is
P=1-Probability of not detecting the flaw by both inspectors
![P=1-\left ( 1-0.9\right )\left ( 1-0.7\right )](https://tex.z-dn.net/?f=P%3D1-%5Cleft%20%28%201-0.9%5Cright%20%29%5Cleft%20%28%201-0.7%5Cright%20%29)
P=1-0.03=0.97
The rate of change in the graph is about 100, so I would say B has a bigger rate of change than the graph
Answer:
![f(x)=5(x-2)^{2}+6](https://tex.z-dn.net/?f=f%28x%29%3D5%28x-2%29%5E%7B2%7D%2B6)
Step-by-step explanation:
we have
![f(x)=5x^{2} -20x+26](https://tex.z-dn.net/?f=f%28x%29%3D5x%5E%7B2%7D%20-20x%2B26)
This is the equation of a vertical parabola open upward
The vertex is a minimum
The equation of a vertical parabola in vertex form is equal to
![f(x)=a(x-h)^2+k](https://tex.z-dn.net/?f=f%28x%29%3Da%28x-h%29%5E2%2Bk)
where
(h,k) is the vertex
Convert the given function to vertex form
Factor the leading coefficient
![f(x)=5(x^{2} -4x)+26](https://tex.z-dn.net/?f=f%28x%29%3D5%28x%5E%7B2%7D%20-4x%29%2B26)
Complete the square
![f(x)=5(x^{2} -4x+4)+26-20](https://tex.z-dn.net/?f=f%28x%29%3D5%28x%5E%7B2%7D%20-4x%2B4%29%2B26-20)
![f(x)=5(x^{2} -4x+4)+6](https://tex.z-dn.net/?f=f%28x%29%3D5%28x%5E%7B2%7D%20-4x%2B4%29%2B6)
Rewrite as perfect squares
------> equation in vertex form
The vertex is the point (2,6)
