Answer:
1418.03
Step-by-step explanation:
86.50 is 6.1% of what amount?
Multiply 86.50 x 100 = 8650
Divide by 6.1 = 1418.03
WAR is given as 57 degrees.
If you draw a line from W to R, the angle WRA would also be 57 degrees.
57 + 57 = 114
The measure of AR = 180 -114 = 66 degrees.
De Moivre's Theorem states that if a complex number is written in the polar coordinate form [ r (cosθ +

sinθ)] and you raise it to the power n, then this can be evaluated by raising the modulus (r) to the power and multiply the argument (θ) by the power. This therefore would give r ⁿ [cos (nθ) +

sin (nθ)].
let A = ∛ <span>(8 cos (4π / 5) + 8 i sin (4π / 5))
</span>⇒ A = ∛ <span>(8 [cos (4π / 5) + i sin (4π / 5)])
</span>
Now by applying De Moivre's Theorem,
⇒ A =

[cos (

) +

sin (

)
⇒ A = 2 [ cos (

) +

sin (

)
⇒ A = 2 [0.0117 +

0.01297 ] rads
Answer:
4x² - 10x + 1
Step-by-step explanation:
(3x-1) + (x+2) + (3x² - 11x) + (x² - 3x)
3x - 1 + x + 2 + 3x² - 11x + x² - 3x
1 - 10x + 4x²
= 4x² - 10x + 1
