Answer:
28 ways
Step-by-step explanation:
After placing 1 ball in each of the seven bins, there are two balls left.
If we place both balls in a single bin, there are 7 different ways to place the balls (place both on bins 1 through 7).
If we place each of the remaining balls in a different bin, the number of ways to place the balls is:
The total number of ways to distribute those balls is 21 + 7 = 28 ways.
X*0.2-7=3
+7 +7
x*0.2=10
divide by 0.2 on both sides
x=50
Answer:
-5
Step-by-step explanation:
The slope of the line is found by
m = (y2-y1)/(x2-x1)
= ( -12.5 - -2.5)/( 7.3 - 5.3)
= ( -12.5 +2.5)/( 7.3 - 5.3)
= -10 /2
= -5
Answer:
Step-by-step explanation:
Let's FOIL this out and get it into standard quadratic format:
. The lack of a linear term in the middle means therewas no upwards velocity, consistent with the object being dropped straight down as opposed to thrown up in the air tand then falling in a parabolic path. The -4.9t² represents the acceleration due to gravity, and the 490 represents the height from which the object was dropped. The constant in a quadratic that is modeling parabolic motion always represents the height from which the object was dropped (or launched). That's how you know.
