Answer:
[-1, 9], [-2, 10], [-3, 11], [1, 7]
Step-by-step explanation:
Starting from the y-intercept of [0, 8], I did <em>rise</em><em>\</em><em>run</em><em> </em>by moving one block <em>north</em><em> </em>over <em>one</em> block <em>west</em><em> </em>for the first three coordinates, but retracing back to the y-intercept, I moved one block <em>south</em><em> </em>over <em>one</em> block <em>east</em> for the last coordinate. It does not matter where you go, as long as you follow the pattern within this <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>].
I am joyous to assist you anytime.
Any number ends with 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9
Given any number. The square of this number is the last digit of square of the original numbers units digit.
For example
23*23 ends with 9 (3*3=9)
149*149 ends with 1 (9*9=81)
2564*2564 ends with 6 (4*4=16)
and so on
so all the possible unit digits of a square number are {0, 1, 4, 5, 6, 9}
because:
0*0= 0 ; 1*1=1; 2*2=4; 3*3=9; 4*4=16; 5*5=25, 6*6=36; 7*7=49; 8*8=64, 9*9=81
Thus, the probability that the square of a number selected from any set of numbers being 7, is 0.

Answer:
Angle LKM is 110
Step-by-step explanation:
Since all the angles in a triangle equal 180, and 60 is one angle you can see its an equilaterial triangle.
so x=60
Then 3(60)-70=110
So LKM=110
Answer:}
In polar coordinates P is
P ( 12 ; 2.618 )
Step-by-step explanation:
The point (ectangular coordinates)
P ( -6√3 ; 6 ) P ( x ; y )
Polar coordinates P ( r ; θ )
x = r cos θ
y = r sin θ r > 0 and 0 ≤ θ ≤ 2π
Then
r = √ (x)² + (y)² r = √(36)²*3 +( 36)² r = √144
r = 12 (hypothenuse module always positive)
The point P ( -6√3 ; 6 ) is in second cuadrant between 90° and 180°
angle between r and horizontal axis x is equal to θ
tan α = l.opp/ l.adj. tan θ = y/x tan θ = - 6 /6√3
tan α = - 1/√3
Then α = 180⁰ - 150⁰ = 30⁰ or θ = 150⁰
to express that value in radians we have :
1 π radian = 180⁰ ⇒ 3,1416 radians = 180⁰
x ?? = 150⁰
x = radians
Finally the point is P ( 12 ; 2.618 )
