Answer:
f(x) = 0 on x= -1 and x = -2
Step-by-step explanation:
Given function is:
![f(x) = x^2+3x+2](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E2%2B3x%2B2)
In order to find the value of x on which the function will have value zero we have to factorize the function and find zeroes of the function. The method used will be factorization of polynomial as the function is in polynomial form.
So,
![x^2+3x+2\\=x^2+2x+x+2\\=x(x+2)+1(x+2)\\=(x+1)(x+2)](https://tex.z-dn.net/?f=x%5E2%2B3x%2B2%5C%5C%3Dx%5E2%2B2x%2Bx%2B2%5C%5C%3Dx%28x%2B2%29%2B1%28x%2B2%29%5C%5C%3D%28x%2B1%29%28x%2B2%29)
To find the zeroes, putting the function = 0
![f(x) = 0\\(x+1)(x+2) = 0\\x+1 = 0\\x = -1\\x+2 = 0\\x= -2](https://tex.z-dn.net/?f=f%28x%29%20%3D%200%5C%5C%28x%2B1%29%28x%2B2%29%20%3D%200%5C%5Cx%2B1%20%3D%200%5C%5Cx%20%3D%20-1%5C%5Cx%2B2%20%3D%200%5C%5Cx%3D%20-2)
Hence,
f(x) = 0 on x= -1 and x = -2
Answer:
1.83 x 108 is about 3 times smaller
Step-by-step explanation:
1.83 x 108 = 197.64
6.1 x 105 = 640.5
640.5/197.64 = 3.24
the answer is 399 just go to socratic if you need help with math.
Step-by-step explanation:
you didn't post the questions yk?!
You would multiply 60 x 3.14= 188.4
then round and you get 188 ft
