Answer:
15
Step-by-step explanation:
It is used to see if a graph represents a function because if there is 2 dots or intersecting lines within the other lines then it is not a function. if there is only one line or dot, then yes, it is a function. hope i explained it well.
Answer: 9cm
Step-by-step explanation:
The circumference of a circle is given as: = 2πr
where,
π = 3.142
r = radius = unknown
Since circumference = 56.52cm, we'll slot it into the formula which will be:
Circumference = 2πr
2πr = 56.52
2 × 3.142 × r = 56.52
6.284r = 56.52
r = 56.52 / 6.284
r = 8.99
r = 9cm approximately
Answer:
Step-by-step explanation:
In going from (5, 5) to (10, 8), x (the run) increases by 5 and y (the rise) increases by 3. Thus, the slope of the line connecting the first two points is m = 3/5.
In going from (1, 13) to (4, 8), x (the run) increases by 3 and y (the rise) decreases by 5. Thus, the slope of the line connecting the first two points is m = -5/3
Because these results are negative reciprocals of one another, the two lines are PERPENDICULAR to one another.
Answer: Check
12^10 × 12^(-2) = 12^(10 - 2) = 12^8
________________________________
Second option : ---
3^2 × 4^6 = 3^2 × 4^2 × 4^4 = 12^2 × 4^4
________________________________
Third option : ---
(12^8)^0 = 12^(8 × 0) = 12^0 = 1
________________________________
4th option : Check
12^10 / 12^2 = 12^10 × 12^(-2) = 12^(10 - 2)
= 12^8
________________________________
5th option : Check
2^8 × 6^8 = ( 2 × 6 )^8 = 12^8
