124=100+20+4, 17=10+7
124*17=(100+20+4)(10+7)=1000+200+40+700+140+28=2108
The probability of landing in the shaded area is 2 out of 5. This can be written as a fraction
or a decimal 0.4
Answer: The parabola has its concavity downwards, so we need a function in the model:
With a negative value of 'a'
The vertex is (0,0), so we have that:
The x-coordinate of the vertex is given by the equation:
So we have a function in the model:
With a < 0
The only option with this format is B:
Step-by-step explanation:
Answer:
y = x² + 2
Step-by-step explanation:
Given
x = 
( square both sides )
x² = y - 2 ( add 2 to both sides )
x² + 2 = y
You would need to substitute a number for y. I would probably put 0 for y which would then give you x.
y = 0
x = 1
Then you can easily graph the point. :)
