Answer:
x = (5 + i sqrt(15))/4 or x = (5 - i sqrt(15))/4
Step-by-step explanation:
Solve for x:
2 x^2 - 5 x + 5 = 0
Hint: | Using the quadratic formula, solve for x.
x = (5 ± sqrt((-5)^2 - 4×2×5))/(2×2) = (5 ± sqrt(25 - 40))/4 = (5 ± sqrt(-15))/4:
x = (5 + sqrt(-15))/4 or x = (5 - sqrt(-15))/4
Hint: | Express sqrt(-15) in terms of i.
sqrt(-15) = sqrt(-1) sqrt(15) = i sqrt(15):
Answer: x = (5 + i sqrt(15))/4 or x = (5 - i sqrt(15))/4
90 = (20)(x)
so you have to solve for x
90/.20 =450
answer is 450
Answer:
44 degrees
Step-by-step explanation:
there's two ways u could do this. One is all triangles add up to 180 degrees. u simply ignore the outside angle of 136 degrees, and add 62 and 74, and u get 136. take 180-136, and u get 44.
Another way is all strait angles add up to 180 degrees. take 180-136, and u get 44 degrees
Hope this helps and have a nice day :) :) :)
2/5 * P(2nd red) = 1/7
P(2nd Red) = 1/7 * 5/2
P(2nd Red) = 5/14 or D
