Solve the equation... 64x^3 -x=0 and x^3 +4x^2-x-4=0

zhannawk [14.2K]

x =(-2-√-12)/8=(-1-i√ 3 )/4= -0.2500-0.4330i

x =(-2+√-12)/8=(-1+i√ 3 )/4= -0.2500+0.4330i

x = 1/2 = 0.500

calculate the side lengths a and b to two decimal places angle a is 64 angle b is 85 and line ab is 9.3? PLEASE HELP ASAP

qaws [65]

∠C = 180° - (∠A + ∠B) = 180° - (64° + 85°) = 180° - 149° = 31°
$AC= \frac{9.3*sin(85)}{sin(31)} = \frac{9.3*0.9962}{0.515} =17,99 \\ \\ BC=\frac{9.3*sin(64)}{sin(31)} = \frac{9.3*0.8988}{0.515} =16,2$

Answer:

the first selection is so shaded

Step-by-step explanation:

Each strip is divided into 10 parts. 1/5 will be represented by 2 of those parts, so 2/5 will be represented by 4 of the 10 parts. The 3/10 used on the other gift will be represented by 3 additional parts. So, a total of 7 of the 10 parts of the strip need to be colored to represent the ribbon used.
