Answer:
pi/2 units to the left
Step-by-step explanation:
the formula is y = cos(x-b) so when b is negative, the formula will show a plus sign because minus negative is adding. this means the graph is shifted -pi/2 to the right which is really pi/2 to the left
Answer:
12-3+(2.7x2)-7
Step-by-step explanation:
you would have to divide each number in the equation by 3 which would look like this:
36 / 3 = 12
-9 / 3 = -3
8 / 3 = 2.6666 repeating, which would be rounded up to 2.7
6 / 3 = 2
-21 / 3 = -7
i hope this helps :)
Answer:
C. 45 degree angle
Step-by-step explanation:
let AB be the height of the wall and CD be the height of boy
with BC as distance between them.
we have AE = AB-BE = 3.64-1.54 = 2.1m
and ED = BC = 2.1m
in triangle AED, we have
tanФ = P/B = 2.1/2.1
tanФ = 1
∴ Ф = 45°
Hence the sun is elevated at an angle of 45 °.
