Use the formula

.
So it would be
.

which equals 3/2
(btw. you can also count the blocks)
Answer:
-6/8
Step-by-step explanation:
Slope=y1-y2/x1-x2
Where (X1,y1) is (-11,5) and (X2,y2) is(5,-7)
Slope=5+7/-11-5
=-12/16
= -6/8
So the slope is -6/8
-π/2 < arctan(x) < π/2
So cos(π/2) < cos(arctan(x)) < cos(0)
0 < cos(arctan(x)) < 1
Answer:
Assuming the question is: 3 + 1 16 [I see no "working below."
Step-by-step explanation:
3 + 1 16
48/16 + (16/16 + 1/16) [Make all numbers into fractions using 16 as the denominator. E.g. 48/16 = 3.
Add: 48/16 + (16/16 + 1/16)
(48+16+1)/16
=63/16
[Also equal to 3 15/16]
