Answer:
9
Step-by-step explanation:
7+2=9
Convert to a mixed number by placing the numbers to the right of the decimal over 100. Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator.
-41\25
Answer:
0 and 2
Step-by-step explanation:
![f(x) = -x^2e^{-x}+2xe^{-x}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20-x%5E2e%5E%7B-x%7D%2B2xe%5E%7B-x%7D)
To find zeros set f(x)=0 and solve for x
![0 = -x^2e^{-x}+2xe^{-x}](https://tex.z-dn.net/?f=0%20%3D%20-x%5E2e%5E%7B-x%7D%2B2xe%5E%7B-x%7D)
![0 = -e^{-x}(x^2-2x)](https://tex.z-dn.net/?f=0%20%3D%20-e%5E%7B-x%7D%28x%5E2-2x%29)
now factor out x
![0 = -xe^{-x}(x-2)](https://tex.z-dn.net/?f=0%20%3D%20-xe%5E%7B-x%7D%28x-2%29)
set each factor =0 and solve for x
![x=0](https://tex.z-dn.net/?f=x%3D0)
no solution for x
![x-2=0, x=2](https://tex.z-dn.net/?f=x-2%3D0%2C%20x%3D2)
zeros of f are 0 and 2
Answer:
47.25 ft³
Step-by-step explanation:
The volume of the prism is given by the formula ...
V = Bh . . . . . . . B is the area of the base, h is the height.
The height of the prism is given as 6 ft. The area of the base is the area of the triangular entrance. The formula for that area is ...
A = 1/2bh . . . . . . b is the base, h is the height
Using the given values for the entrance base and height, we get ...
A = 1/2(4.5 ft)(3.5 ft) = 7.875 ft²
Then the volume of the tent is ...
V = (7.875 ft²)(6 ft) = 47.25 ft³
The tent volume is 47.25 cubic feet.
