66x is the correct answer
Answer:
310%
Step-by-step explanation:
Convert the fraction to a decimal, then multiply by 100.
Depending on its position increases its value x10.
EX:
300 30 3 0.3 0.03
The number continually is raised x10 the more you move it to the right and is divided by 10 when you move it to the left
Step-by-step explanation:
For any quadratic equation 
, the quadratic formula is as follows:
From the given quadratic equation, we know that 
, 
and 
. Plugging in these values into the quadratic formula gives us the following:
An angle of pi/2 radians can be transformed into degrees
using the conversion formula (180/pi):
φ =
(pi / 2) * (180 / pi) = 90˚
Therefore an angle of pi/2 rad is just equivalent to 90˚.
Since 90<span>˚ is located on the y-axis, therefore the horizontal component x is
zero. So cosine of this angle is zero.</span>
