Step-by-step explanation:
Xj + Xk/2 = Xm
7 + Xk/2 = 1
to get rid of the bracket, multiply all two sides by the denominator.
2(7 + Xk/2) = 1(2)
7 + Xk = 2
Xk = 2 - 7
Xk = -5
Yj + Yk/2 = Ym
2 + Yk/2 = -2
to get rid of the bracket, multiply all two sides by the denominator.
2(2 + Yk/2) = -2(2)
2 + Yk = -4
Yk = -4 - 2
Yk = -6
Therefore the coordinates of point K is (-5,-6)
Answer:
true
Step-by-step explanation:
sinA² + cosA²=1
⇔(1/2)² + cosA²=1
⇔cosA=±(√3/2)
Answer:
Linear polynomial
Step-by-step explanation:
10 + 7x
The highest power of the variable is the degree of the polynomial.
Power of x is 1
Degree of the polynomial is 1
So, it is Linear polynomial
Answer:
The median is 37
Step-by-step explanation:
The median is the middle number in the set when organizaed from low to high:
