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>
Answer:
x=2x, y=5y
Step-by-step explanation:
180-108=72+120=192,360-192=168
Answer:
D. $236.00
Step-by-step explanation:
128+45+63 = 236
Answer:
C. 1.5w^2 + 7.5w + 9
Step-by-step explanation:
Without frame:
The width is w. The height is 1.5w.
With frame:
The width is w + 1.5 + 1.5 = w + 3
The height is 1.5w + 1.5 + 1.5 = 1.5w + 3
The area of the framed portrait is height * width
area = (1.5w + 3)(w + 3)
area = 1.5w^2 + 4.5w + 3w + 9
area = 1.5w^2 + 7.5w + 9
