Answer:
5.4%
Step-by-step explanation:
percent error = |(measured - actual value) / actual value * 100| = |(7.8-7.4) / 7.4 * 100| ≈ 5.4%
Answer: 4π/15, 4π/3 and 28π/15 (in radians)
Step-by-step explanation:
Recall that 
= 
This implies that
Therefore the values of 
between 0 and 2π are 48, 240 and 336. (All in degrees)
48 degrees= 4π/15 rad
240 degrees =4π/3 rad
336 degrees = 28π/15 rad
Answer:
q = 94
p = 18
Step-by-step explanation:
The triangles are congruent so q = 94
Add q + 68 same as 94 + 68 = 162
Subtract 162 from 180 to get p
180 - 162 = 18
Hope this helps!
This can't be factored with rational numbers.
Answer:
7-8i
Step-by-step explanation:
to find as complex conjugate, simply change the sign of the imaginary pert (the part with the i). this means that is either goes from positive to negetive or from negetive to positive
as as general rule,the complex conjugate of a +bi is a-bi
