Answer:
1
Explanation:
According to the Unit Circle, sin π\6 is ½, so we plug this into the cosine function to get this:
cos π\6 - π\6 → cos 0 >> 1

*** Plus, we need to make sure that the x-value falls in between 0 and π\2, which it did, so no need to worry.
Answer:
a= d and b= b
Step-by-step explanation:
circumference falls hand and hand with diameter and radius
a has a circumference of about 301 inches
b is about 62 inches
c is about 75 inches
d is about 314
Y=-3x+4
Gradient, m= -3
Parallel lines have equal gradients;
So, equation II,
y=mx+c
y=-3x+c
Replacing for x and y using point (-4, 6)
6=-3(-4)+c
6=12+c
6-12=c
c=-6
y=-3x-6
Wait isn’t it 30 or am I reading it wrong?
