Hey there, just multiply 2.2 by 5, 2.2×5=11. Therefore, the lowest common multiple of 2.2 and 5 is 11.
Parameterize the intersection by setting

, so that


The length of the path

is then given by the line integral along

,

where

. We have



and so the line integral is

This result is fortuitous, since we can write

and so the integral reduces to
Step-by-step explanation:
from (2)
x-y=2
y=x-2 (3)
subs (3) into (1)
x²-2x+(x-2)=8
x²-2x+X-10=0
x²+x-10=0
quadratic formula
x= (-1±√1²-4×1×(-10))/2(1)
X=( -1±√41)/2
X=(-1+√41)/2
=
x=(-1-√41)/2

<u>Problem N 10) Find the surface area</u>
we know that
the surface area is equal to
SA=2*area of the base+perimeter of base*height
<u>Find the area of the base B (area of a square)</u>

<u>Find the perimeter of the base P (perimeter of a square)</u>

height=68 mm
substitute in the formula

therefore
<u>the answer Problem N 10) is</u>
the surface area is 
<u>Problem N 11) Find the volume</u>
we know that
the volume is equal to
V=area of the base*height
<u>find the area of the base A (area of a triangle)</u>

height =4 ft
substitute in the formula

therefore
<u>the answer Problem N 11) is</u>
the volume is equal to
