Answer:
10 cm
Step-by-step explanation:
The diameter is a chord (line) that connects on both ends of a circle which includes the center point of the circle. The radius comes from the center point of the circle to one end of the circle.
Diameter is therefore 2 radii (radius).
So if diameter is given and you want to find the radius, divide it by two to find the answer.
20 ÷ 2 = 10 cm
Answer:
f'(x) = (x + 1)/15
Step-by-step explanation:
f(x) = 15x -1,
Think of the term "f(x)" as a single variable, then solve for the term "x", manipulate the equation like how one would manipulate a literal equation, by inverse operations.
f(x) = 15x - 1
+1 +1
f(x) + 1 = 15x
/15 /15
(f(x) + 1)/15 = x
This means that (denote in the way one would denote an inverse of a function);
f'(x) = (x + 1)/15
Answer:
6 segments are required to connect each point to every other point.
Step-by-step explanation:
If four points are placed on a circle.Then as we know the segment is a line that join two points.
Now as we are given four points on the circle.
- so we will firstly start with the first point; the first point requires 3 segments to connect to the remaining three points.
- Next second point will just require 2 segments to connect to the two points as it is already connected to the first point.
- similarly third point requires just one segment to connect to the last point as it is already connected to first and second point as done above.
- and hence by the above three steps the fourth point is connected to all the points.
Hence, 6 segments are required to connect each point to every other point.
This question is incomplete.
50% because you first subtract the original price from the new price so 126-84 equals 42 then you divide that by the original price 84 which will give you .5 which turns to 50%
