Answer:
Step-by-step explanation:
Given the function f(x)=x-3
So we want to know the value of the function when
1. x=1
Then, f(x) =x-3
Let substitute x=1
f(1)=1-3
f(1)=-2
2. x=2
Then, f(x) =x-3
Let substitute x=2
f(2)=2-3
f(2)=-1
3. x=4
Then, f(x) =x-3
Let substitute x=4
f(4)=4-3
f(4)=1
4. x=5
Then, f(x) =x-3
Let substitute x=5
f(5)=5-3
f(5)=2
5. x=8
Then, f(x) =x-3
Let substitute x=8
f(8)=8-3
f(8)=5
f(x)=x-3
x. 1 2 4 5 8
f(x). -2 -1 1 2 5
Answer:
Average=29/6=4.83
Step-by-step explanation:
F(0)=0^2-4=-4
F(1)=1^2-4=-3
F(2)=2^2-4=0
F(3)=3^2-4=5
F(4)=4^2-4=10
F(5)=5^2-4=21
The average is =total/6
Average=29/6=4.83
Answer: intersecting but not perpendicular
Step-by-step explanation: Let's start by eliminating a few options.
First off, parallel lines are coplanar lines that do not intersect.
In the diagram shown, lines <em>i </em>and <em>k</em> do intersect
so option A doesn't make any sense.
We can also eliminate option C because by definition,
parallel lines <em><u>do not intersect </u></em> so we can cross this off.
We also can't conclude that lines <em>i</em> and <em>k </em>are perpendicular,
because we don't have a box at the vertex and from the
diagram shown, it doesn't look like they form a perfect right angle.
That leaves us with option D.
Notice that these two lines cross at a point.
When two lines cross at a point, we say that they intersect.
So they are intersecting lines but not perpendicular.
