Answer:
Willy Wonka
Step-by-step explanation:
Given data
it takes Charlie 45 minutes walking at 2.5 km/hr
speed = distance /time
distance= speed*time
distance= 2.5*45
distance= 112.5 km
it takes Willy Wonka 15 minutes walking at 3.5 km/hr
distance= speed*time
distance= 3.5*15
distance= 52.5 km
Hence Willy Wonka stays closer
Answer: The point slope solution is y+4 = -(1/2)(x-4) which is y + 4 = -(.5)x + 2 or y = -(.5)x -2.
Step-by-step explanation:
The answer is 3, because the other two sides are 3 and the angle is 60, so the other angles will have to be 60. That means it is an equilateral triangle.
Answer:
The answer is the second option
Step-by-step explanation:
Let u=x^2.
![( {x}^{2} ) {}^{2} - 9( {x}^{2} ) + 8( {x}^{2} ) {}^{0}](https://tex.z-dn.net/?f=%28%20%7Bx%7D%5E%7B2%7D%20%29%20%7B%7D%5E%7B2%7D%20%20-%209%28%20%7Bx%7D%5E%7B2%7D%20%29%20%2B%208%28%20%7Bx%7D%5E%7B2%7D%20%29%20%7B%7D%5E%7B0%7D%20)
![{u}^{2} - 9u + 8](https://tex.z-dn.net/?f=%20%7Bu%7D%5E%7B2%7D%20%20-%209u%20%2B%208)
![(u - 1)(u - 8)](https://tex.z-dn.net/?f=%28u%20-%201%29%28u%20-%208%29)
![u = 1](https://tex.z-dn.net/?f=u%20%3D%201)
![u = 8](https://tex.z-dn.net/?f=u%20%3D%208)
Set this equal to x^2
![{x}^{2} = 1](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%3D%201)
![x = 1](https://tex.z-dn.net/?f=x%20%3D%201)
or
![x = - 1](https://tex.z-dn.net/?f=x%20%3D%20%20-%201)
![{x}^{2} = 8](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%3D%208)
![x = 2 \sqrt{2}](https://tex.z-dn.net/?f=x%20%3D%202%20%5Csqrt%7B2%7D%20)
or
![x = - 2 \sqrt{2}](https://tex.z-dn.net/?f=x%20%3D%20%20-%202%20%5Csqrt%7B2%7D%20)
