Step-by-step explanation:
The volume of a prism is V = Bh, where B is the area of the base shape and h is the height of the prism. Find the area of the parallelogram that is the base, length x width, then multiply this by the height of the prism. l x w x h.
Answer:
102.86
Step-by-step explanation:
cos 55 = 59/x
x = 59/cos 55
x = 102.86
Answer:
Standard Complex Form : 
Step-by-step explanation:
We want to rewrite this expression in standard complex form. Let's first evaluate cos(5π / 6). Remember that cos(x) = sin(π / 2 - x). Therefore,
cos(5π / 6) = sin(π / 2 - 5π / 6),
π / 2 - 5π / 6 = - π / 3,
sin(- π / 3) = - sin(π / 3)
And we also know that sin(π / 3) = √3 / 2. So - sin(π / 3) = - √3 / 2 = cos(5π / 6).
Now let's evaluate the sin(5π / 6). Similar to cos(x) = sin(π / 2 - x), sin(x) = cos(π / 2 - x). So, sin(5π / 6) = cos(- π / 3). Now let's further simplify from here,
cos(- π / 3) = cos(π / 3)
We know that cos(π / 3) = 1 / 2. So, sin(5π / 6) = 1 / 2
Through substitution we receive the expression 25( - √3 / 2 + i(1 / 2) ). Further simplification results in the following expression. <u>As you can see your solution is option a.</u>

Answer:
The answer is 3
Step-by-step explanation:
0.7*3 = 2.1
Think of it this way
its basically 7 times what equals 21?
then you find out 7 timex 3 = 21
and then put the decimals
0.7 times 3 (0.7 + 0.7 + 0.7) = 2.1
