Answer:
A
Step-by-step explanation:
To find the slope of a line, we can use the slope formula:
So, we will need to choose two points from the graph. Any two points will work.
Let’s choose (0, -1) and (1, 2).
So, we will let (0, -1) be (x₁, y₁) and (1, 2) be (x₂, y₂). Substitute these values into the slope formula:
Evaluate:
Therefore, the slope of the line is 3.
Hence, our answer is A.
Answer:
The ratio is 6:2:1.
Step-by-step explanation:
Let's denote:
Blue counter b
Red counter r
Yellow counter y.
There is given
r=3b (three times more red as blue) [1]
and
b=2y (twice more blue as yellow.) [2]
Now, replacing [2] to [1] gives
3*2y=r
6y=r.
Hence, the ratio is 6:2:1, because r=6y and b=2y.
The ball is the same height as the building between 8 and 10 seconds after it is thrown.
The ball reaches it's maximum height about 4 seconds after it is thrown
