Answer:
(a, b) = (0, -15)
Step-by-step explanation:
In "cis" form the product of two complex numbers is the product of their magnitudes at the angle that is the sum of their angles. I find this the easiest way to multiply complex numbers.
z1 × z2 = (3 cis π)(5 cis π/2)
= (3·5) cis (π +π/2)
= 15 cis 3π/2
Of course, "cis" is short for "cosine + i·sine", so you have ...
z1 × z2 = 15 cis 3π/2 = 15(cos(3π/2) +i·sin(3π/2))
= 15(0 +i·(-1))
= 0 -15i
(a, b) = (0, -15)
The volume is 905.32 i believe
12(12)=144, 144(3.14)=452.16, 452.16(6)=2712.96, 2712.96/3=904.32
The measure of center and range to be used to compare the population is the median and the inter quartile range.
<u>Explanation:</u>
You utilize the median and the interquartile range (IQR) to portray skewed distributions of information. To look at two populaces, utilize the mean and the MAD when the two populations are symmetric. Utilize the middle and the IQR when possibly one or the two circulations are slanted.
In statistics and probability theory, the median is the worth isolating the higher half from the lower half of an information test, a populace or a likelihood circulation. For an informational collection, it might be thought of as the "center" esteem.
Answer:
C. 6 2/3
Step-by-step explanation:
3/5 = 0.6
4 divided by 0.6 = 6.7 (rounded to the nearest tenth)
2/3 = .7 (rounded to the nearest tenth)
therefore , your answer is C
Answer:
at x = 
, 
= -3.5
Step-by-step explanation:
The given equation is
Now, substitute the value of x = in the above equation.
The given equation simplifies to,
now, 
So, the equation become
-3(2) + 2 + (1/2) = 
= -3.5
So, at x = , = -3.5
