We know that
If the scalar product of two vectors<span> is zero, both vectors are </span><span>orthogonal
</span><span>A. (-2,5)
</span>(-2,5)*(1,5)-------> -2*1+5*5=23-----------> <span>are not orthogonal
</span><span>B. (10,-2)
</span>(10,-2)*(1,5)-------> 10*1-2*5=0-----------> are orthogonal
<span>C. (-1,-5)
</span>(-1,-5)*(1,5)-------> -1*1-5*5=-26-----------> are not orthogonal
<span>D. (-5,1)
</span>(-5,1)*(1,5)-------> -5*1+1*5=0-----------> are orthogonal
the answer is
B. (10,-2) and D. (-5,1) are orthogonal to (1,5)
Answer -0.54 a line on both 5 and 4
Step-by-step explanation:
Hey!
------------------------------------------------
Steps To Solve:
17 - 2v = -53
~Subtract 17 to both sides
17 - 2v - 17 = -53 - 17
~Simplify
-2v = -70
~Divide 2 to both sides
-2v/-2 = -70/-2
~Simplify
v = 35
------------------------------------------------
Hence, the answer is
