Drawing a diagonal means to connect a vertex with another non-adjacent vertex.
So, for each vertex, we have 8-3=5 possible diagonals. This leads to a total of 8*5=40 diagonals.
We have to divide this number by 2 though, because in this way we're counting each diagonal twice (connecting points AB or BA gives the same diagonal).
So, an 8 sided shape has 20 diagonals.
Answer:
a) The value of If(i)I = √2.
Step-by-step explanation:
Here the given function is f(x) = 1 - x
To Find: If(i)I
First;y, let us find the value of f(i).
Substituting x = i in f(x) , we get:
f(i) = 1- i
Now, The modulus value of a function P = A + B is written as :
So, here calculating the value of If(i)I :
⇒ I1-1I = √2
or, If(i)I =√2
Hence, the value of If(i)I for f(x) = 1 -x is√2.
Answer:
y=5
Step-by-step explanation:
First, write your current equation. Y=0x+b. Next, subsitute the x and y for the coordinates (2,5) to find the y-intercept. It should look like this: 5=0(2)+b. 2 times 0 equals 0, so you have 5=b, which means 5 is your y-intercept. Now, go back to the original equation Y=0x+b and replace the b with 5. However, since the slope is 0, that means it will be a horizontal line. So, you can just write it as y=5.
They had 30 I know this because I did 37 times 32x divided my y plus 15
