After every drop,the ball bounces to half it's previous height. With that understood.
1st drop -The ball drops 10m
1st bounce - 5m up
2nd drop - 5m down
2nd bounce - 2.5m up
3rd drop - 2.5m down
3rd bounce - 1.25m up
4th drop - 1.25m down
4th bounce - 0.625m up
5th/last drop - 0.625m down
To find the total vertical distance, you add them all.
10+5+5+2.5+2.5+1.25+1.25+0.625+0.625
=29.25m travelled in all.
The up and down rectangles have an area of 6 * 4 = 24 ft^2
There are 2 of them so area = 2*24 = 48.square feet.
There is 1 floor which has an area of 4*6 = 24 square feet
The area of one of hte triangles is 1/2 4 *3.46 = 6.92
Again, there are 2 of them so the total area for the triangles is 13.84
The total area is 48 + 24 + 13.84 = 85.84 square feet.
Answer:
Answer is B
0.008
Step-by-step explanation:
Answer:
1. 4y = 3x - 8
2.y-7 = -2(x + 4)
Step-by-step explanation:
1. The general equation form is;
y = mx + b
m is slope b is y-intercept
so we have;
y= 3/4x - 2
Multiply through by 4
4y = 3x -8
2. The point-slope form is;
y-y1 = m(x-x1)
y-7 = -2(x + 4)
