Answer:
Slope: -1/2
Step-by-step explanation:
Take a look at the slope formula
2-(-4)/3-(-1)
=-2/4
=-1/2
.944
2 1/9 = 2.111
7/6 = 1.167
2.111-1.167= .944
13pi/12 lies between pi and 2pi, which means sin(13pi/12) < 0
Recall the double angle identity,
sin^2(x) = (1 - cos(2x))/2
If we let x = 13pi/12, then
sin(13pi/12) = - sqrt[(1 - cos(13pi/6))/2]
where we took the negative square root because we expect a negative value.
Now, because cosine has a period of 2pi, we have
cos(13pi/6) = cos(2pi + pi/6) = cos(pi/6) = sqrt[3]/2
Then
sin(13pi/12) = - sqrt[(1 - sqrt[3]/2)/2]
sin(13pi/12) = - sqrt[2 - sqrt[3]]/2
Answer:
3 1/3, or 10/3
Step-by-step explanation:
1 2/3 * 2 = 5/3 * 2 = 10/3 = 3 1/3
Answer:
#1 THE LENGTH IS 24 FT, WIDTH IS 12 FT..... #2 DISTANCE IS 7
Step-by-step explanation:
ON PROBLEM ONE ITS SAYING FOR EVERY 1 CM ITS EQUALY TO 4 FEET, SO MULTIPLY 6CM*4 FEET OR 1*4 + 1*4 + 1*4 + 1*4 + 1*4 +1*4=24
YOU DO THE SAME FOR THE WIDTH WHICH WOULD BE 3CM*4FT=12
ITS THE SAME FOR THE SECOND PROBLEM TO YOUD DO 2*3 1/2=7
