Answer:
Step-by-step explanation:
The equation for solving for density is:
Density = mass / volume
Then plug in the values:
Density = 6 g / 12 mL
Divide and don't forget the units!
Density = 0.5 g/mL
Answer:
7,000 days
Step-by-step explanation:
63,000 ÷ 9 = 7,000
The x coordinate of the vertex will be the average of the two zeros, here -3 and 5, so x=(-3+5)/2 = 1, f(1)=(1+3)(1-5) = -16.
Answer: (1, -16)
Let's do it some other ways. How about completing the square to turn f in to vertex form?
f(x) = (x+3)(x-5) = x² - 2x - 15 = (x² - 2x + 1) - 1 - 15 = (x-1)² - 16
and now we can read off (1, -16) as the vertex.
The other method is the vertex is x= - b/2a = - (-2)/2(1) = 1.
Three methods, same answer. Good.
Answer:
39%
Step-by-step explanation:
you would divide the number of times the coin landed on heads by the total times thrown which give s you .3857 you move the decimal over twice to give you 38.5 and round up to 39%
The function is linear, i.e. it is a polynomial of degree 1, and thus it represents a line.
So, we'll find only one zero:
