Answer:
8x^2-18x-56
Step-by-step explanation:
(4x+7)*(2x-8)=
4x*2x+4x*(-8)+7*2x+7*(-8)=
8x^2-32x+14x-56=
8x^2-18x-56
Answer:
The correct answer is option C: (8, 14).
Step-by-step explanation:
The car's displacement in vector form can be found by subtracting the initial points from the final points.
Initial: (x₁, y₁) = (-3, -5)
Final: (x₂, y₂) = (5, 9)
For the x-coordinate, we have:
![d_{x} = x_{2} - x_{1} = 5 - (-3) = 8](https://tex.z-dn.net/?f=%20d_%7Bx%7D%20%3D%20x_%7B2%7D%20-%20x_%7B1%7D%20%3D%205%20-%20%28-3%29%20%3D%208%20)
And for the y-coordinate, we have:
![d_{y} = y_{2} - y_{1} = 9 - (-5) = 14](https://tex.z-dn.net/?f=%20d_%7By%7D%20%3D%20y_%7B2%7D%20-%20y_%7B1%7D%20%3D%209%20-%20%28-5%29%20%3D%2014%20)
The car's displacement in vector form is:
Therefore, the correct answer is option C: (8, 14).
I hope it helps you!
Answer: Option B.
Step-by-step explanation:
In the graph we can see the graph of a quadratic equation (from this we could conclude that the graph will not change the current direction for the arms, so the arms will keep going down), and we also can see that as x increases in absolute value, the value of y decreases.
Then we could conclude that as IxI is really big, we will have that f(x) goes to minus infinity
x -->∞, f(x) --> -∞
x--> -∞, f(x) --> -∞
Then the correct option is B
Answer:
No. No.

Answer:
I think that it is something to do with the atmosphere and the way that the light bounces around it. Here is some information from a website to back this up. "The Short Answer: Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves."
