i think that you are multiplying them so the answer is 3553.5
and if your adding it would be 122.1
Answer: The answer is (c) 3 - 4i.
Step-by-step explanation: We are given a point located on the complex plane and we are to select the correct complex number that is represented by this point.
We can see that the co-ordinates of the point on the plane are (3, -4).
Since the point (a, b) can be written in the form a + bi, where 'a' is the measurement along X-axis and 'b' is the measurement along Y-axis, so the point (3, -4) an be written in the following form:
(3, -4) = 3 + (-4)i = 3-4i.
Thus, (c) is the correct option.
Answer:
396 square inches
Step-by-step explanation:
First we must find the overall surface area of the cake, which will the total area of all of the faces.
The cake is a rectangular prism, meaning the faces are all rectangles and opposite faces will be identical.
As opposite faces are identical, the area of only 3 faces need to be found, and a formula can be crafted:
, where l is length, w is width, and h is height.
For demonstration purposes, the length will be 12 and the width will be 15.
Substituting, we get:
![A = 2 ((12)(15) + (15)(4) + (12)(4))\\A = 2(180 + 60 + 48)\\A = 2(288)\\A = 576\\](https://tex.z-dn.net/?f=A%20%3D%202%20%28%2812%29%2815%29%20%2B%20%2815%29%284%29%20%2B%20%2812%29%284%29%29%5C%5CA%20%3D%202%28180%20%2B%2060%20%2B%2048%29%5C%5CA%20%3D%202%28288%29%5C%5CA%20%3D%20576%5C%5C)
Now, we must subtract the area that is not covered by frosting. As there is only a lack of frosting on the base, we subtract the area of the base.
![A = 576 - lw\\A = 576 - (12)(15)\\A = 576 - 180\\A = 396](https://tex.z-dn.net/?f=A%20%3D%20576%20-%20lw%5C%5CA%20%3D%20576%20-%20%2812%29%2815%29%5C%5CA%20%3D%20576%20-%20180%5C%5CA%20%3D%20396)
The probability for each and every throw is always 1/2 independent of what has happened before.
P(6_T) = 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 = 1/64 or 0.015625
