Answer:
they form a 90 degree angle
Step-by-step explanation:
perpendicular (⊥) always implies 90 degree angles
parallel (║) always implies they never intersect
Answer:
Fibonacci numbers is a series of numbers in which each number is sum of two preceding numbers.
Step-by-step explanation:
It is a sequence in mathematics denoted F. Fibonacci numbers have important contribution to western mathematics. The first two Fibonacci numbers are 0 and 1, all the numbers are then sum of previous two numbers. Fibonacci sequence is widely used in engineering applications for data algorithms. Fibonacci sequence is basis for golden ratio which is used in architecture and design. It can be seen in petals of flower and snail's shell.
Answer:
The coordinates of the midpoint of the segment are (-5.5,0,-8)
Step-by-step explanation:
In this question, we are tasked with calculating the midpoint of the segment PQ.
To calculate this, we employ the use of a mathematical formula as follows;
The coordinate of the midpoint are = {(x1+x2)/2, (y1+y2)/2 , (z1+ z2)/2}
Thus we have;
{(-7-4)/2, (3-3)/2 , (-7-9)/2} = (-11/2, 0/2, -16/2)
= (-5.5,0,-8)
For this problem, we can move all the X's to one side and all the regular numbers to the other.
7x comes over and become -7x
10 goes over and becomes -10.
5x+7x-7x=-3-10+13+12.
-3-10=-13, which cancels out the positive 13.
-7x+7x=0 which cancels each other out.
Now, 5x=12
Divide each side by 5.
x=2.4 <--- final answer.
