Answer: Circumference = 25.12
Explanation:
Circumference = pi x d
C = 3.14 x 8
C = 25.12
Answer:
Hit me with them
Step-by-step explanation:
The given equation is in point-slope form.
The general form of an equation in point slope form is:

Here m is the slope and

and

are the coordinates of the point.
So in given equation the slope is 2/3, and the coordinates of point are (1,3)
Answer:
2a + 10
Step-by-step explanation:
the number = 2(a + 5)
= 2a + 10
We can solve this problem using discriminant.
x^2-4x-12's discriminant is
(-4)^2-4*-12=16+48 which is clearly larger than 0
This means that it crosses over the axes 2 times.
In case you don't know what discriminant is, its in equation ax^2+bx+c
the discriminant is b^2-4ac.
If its positive it has 2 crosses with x axis, if negative then 0 crosses, if 0 then 1 cross.
Hope this helped at least a little bit :D
