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:
X=8
Step-by-step explanation:
Opposite side angles on the transversal are congruent.
SO 6x-2=46
46+2=48
48/6=8
X=8
Answer:
-2x+3(-5x+1)=-2x+(-15x+3)
=-2x-15x+3
=-17x+3
-5/3a+1/8-1/6a-1/2=-5/3a-1/6a+1/8-1/2
=-40/24a-4/24a+3/24-12/24
=-44/24a-9/24
=-11/6a-3/8
3(1/5x-1/7)=3/5x-3/7
Hence, ans: C
-1.5w+7.5=1.5(-w+5)
=-1.5(w-5)
Hence, ans: A
