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)

Height of cylinder = h = 7.006 feet
Step-by-step explanation:
<u>We are given:</u>
Volume of cylinder = 1408 cubic feet
Radius = 8 feet
<u>We need to find:</u>
Height of cylinder = ?
<u>Formula used:</u>
Putting values in the formula and finding height:
So, Height of cylinder = h = 7.006 feet

Answer:
An ant
Step-by-step explanation:
We would do process of elimination so first you would see in an apple would weigh 5 oz and it weighs more so that means a cat and chair could not be it either since they are heavier than an apple so the only logical answer would an an ant.
I would say sum because you are adding and it is 11r^3+11
