we have
Equate the expression to zero to find the roots
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
square roots both sides
the roots are
so
therefore
<u>the answer is the option</u>
Answer:
x = 10
Step-by-step explanation:
<span>The
third root of the given complex number 27(cos(pi/5)+isin(pi/5)) is <span>3(cos(pi/15)+i sin(pi/15))
</span>The solution would be like this
for this specific problem:</span>
<span>2^5 =
32 so you need a 2 out front the 5th root of cos(x) + i sin(x) is
cos(x/5) + i sin(x/5). Additionally, 5 roots are located at even
intervals around the circle. They are spaced every 2 pi/5 or 6 pi/15 radians.
</span>
<span>Roots
are located at pi/15, pi/15+ 10pi/15 = 11 pi/15 and pi/15+ 20pi/15 = 21 pi/15
(or 7 pi /5 ).</span>
Answer:
14 = 8 + 2d
Step-by-step explanation:
Odometer is a device that is equipped in the vehicles to count the distance traveled by the vehicle.
It has been given in the question that,
Distance between beach and her friend's house = d miles.
Distance between Brenna's house and her friend's house = 8 miles
Total distance traveled by Brenna = 14 miles.
Starting from the Brenna's house, we will add each distance traveled till the end of her journey and will make it equal to the 14 miles.
So,
Total distance = Distance between Brenna's house and her friend's house + Distance between her friend's house and beach + Distance between beach and her friend's house
Thus, we can now put the values as,
14 = 8 + d + d
We will get the final equation as
14 = 8 + 2d
Initial is 12
Percent 1.05(I think but you might have to convert it)
Y=12(1.05)(5)
Y=63
