Step-by-step explanation:
do this is 2 parts
total = square + 1/2 circle
area of a square is side * side or ... b/c the sides of a square are the same 2* side
area of a circle is Pi* r^2
total area = 12*12 + 1/2 * pi * 6^2
ta = 144 + 56.52
ta = 200.52
ta da.. :P total area is 200.52
Answer:
The probability that the first block will be green and the second will be yellow is or 0.111.
Step-by-step explanation:
We are given that a bag contains 5 yellow blocks, 2 green blocks and 3 blue blocks.
Also, we choose one block and then another block without putting the first one back in the bag.
<u>Firstly, as we know that Probability of any event is given by ;</u>
Probability of an event =
SO, <em>Probability that the first block will be green</em> =
Here, Number of green blocks = 2
Total number of blocks in bag = 5 yellow + 2 green + 3 blue = 10 blocks
So, Probability that the first block will be green =
<em>Similarly, Probability that the second block will be yellow</em> =
Here, Number of yellow blocks = 5
Total number of remaining blocks in bag = 10 - 1 = 9 blocks {because we haven't put the block back after choosing the first}
So, Probability that the second block will be yellow =
<u>Now, Probability that the first block will be green and the second will be yellow</u> =
= = 0.111
Hence, the required probability is 0.111.
Answer:
Step-by-step explanation:
The parametrization of an ellipse center at origin and counter-clockwise is given by the formulas:
Where “a” is the radius of the major axis along the x-axis and “b” is the radius of the minor axis along the y-axis. Since the major diameter along the x-axis is 14 then its radius is its half, thus a=7. Similarly, since the minor diameter along the y-axis is 10, then its radius is half of it, thus b=5
Therefore, the parametric equations for the ellipse become:
Notice at t=0 we get:
which satisfies that the parametrization at t=0 makes the point (7,0)
