4x/4= x
4y/4 = y
8/4=2
Answer: y=2
Answer:
D
Step-by-step explanation:
maximum at 12am which is time, t = 0 and 12pm which is time, t = 12
so we’ll use a cosine function since no phase shift is given.
period, T: 1 cycle = 2π and time taken to complete one cycle is 12hrs
T = 2π/(12) = ⅙π
med-line = ½(1 + 2.2) = 1.6
and thus amplitude = 1.6 - 1 = 0.6 or 2.2 - 1.6 = 0.6
h(t) = 0.6 cos(⅙πt ) + 1.6

Answer:
X= - 1/6
Step-by-step explanation:
Well its 16/7 = -8x
We can do a proportion over here
so 16/7 = -8x/1
Now just cross multiply to solve proportion
-56x=16
divide -56 to isolate x
x= 16/-56
Now simplify 16/-56
which is -1/6
So negative 1/6
Answer:
0.136m
Step-by-step explanation:
This is because if you draw a diagram, and label all the sides of the triangle (opp, hyp, adj), the adjacent angle is 3m. You can now use the sine rule to find the hypotenuse (length of ladder) by doing: cos 20= 3/h. You divide cos(20) by 3 and you get the answer of 0.13602m.
Answer:
<u><em>-x+2y=6 and x+3y=0</em></u>
Step-by-step explanation:
Ax+By=C
y=1/2 x+ 3
y= x+6/2
2y=x+6
-x+2y=6------------1
y-2=-1/3(x+6)
3(y-2)= -(x+6)
3y-6=-x-6
3y+x=-6+6
x+3y=0------------2
