Answer:
-20x + 15
Step-by-step explanation:
-9=6/v
You have to multiply v both sides because
6/v x v = 6 and helps you get rid of the v on the right side.
If you multiply by 6, 6/v x 6 = 36/v, that’s why it don’t work.
Answer:
-9=6/v
-9v=6
v=-6/9
v=-2/3
Answer:
0.0001% probability that a randomly selected person in the United States will be struck by lightning this year
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
304 hit by lightning, so 
Total outcomes:
300,000,000 total people, so 
Probability:

0.0001% probability that a randomly selected person in the United States will be struck by lightning this year
Answer:
a) f(x) = -2x² + 4x
Explanation:
To find the standard form we need to solve the equation as:

So, the standard form is f(x) = -2x² + 4x
To make the graph we will use the initial form because when the equation is written like f(x) = a(x-h)²+k, the coordinate (h,k) is the vertex of the parabola
So, in this case, the vertex of the parabola is the point (1, 2)
On the other hand, we can find a point in the graph. For example, if x is equal to 0, then f(x) is equal to:
f(x) = -2(x-1)² + 2
f(0) = -2(0-1)² + 2
f(0) = -2(-1)² + 2
f(0) = - 2 + 2
f(0) = 0
So, the parabola passes through the point (0,0) and has a vertex in the point (1, 2). Then, the graph is:
Answer:
B. (x - 4)² + y² = 12
Step-by-step explanation:
Rewrite in standard form to find the center (h,k) and radius r.
