Answer:
Step-by-step explanation:
The given equation is:
,
Now, putting x=2 in above equation,


Now, put y=3 in the given equation,



Putting x=6,



Putting x=0,


Putting x=3,



Putting y=0,


Putting y=8,



Answer:
Assuming the other side is 30, x=12
Step-by-step explanation:
X+(X+6)=30
2x+6=30 (open the brackets by distributing the plus sign inside)
2x=24 (subtract 6 from both sides)
x=12 divide both sides by 12
This makes sense because of x is 6, and x+6 is 18, 6+18=30.
Answer:
\int\limits^{\pi/2} _0 (1+4cos^{2} (2x)dx
Step-by-step explanation:
Arc length is calculated by dividing the arcs in to small segments ds
By pythagoren theorem

then integrate ds to get arc length.
We are given a function as
y = sin 2x in the interval [0, pi/2]
To find arc length in the interval
Arc length 
Hence arc length would be
B)
Answer:
1/4 or 0.25
Step-by-step explanation:
- 3.2(4m + 10) – (-7.2m) = 37
- 12.8m+32+7.2m=37
- 20m= 37-32
- 20m=5
- m=5/20= 1/4 or 0.25
False
True
True
