Answer:
28.26 units
Step-by-step explanation:
Given:
Radius (r) = 9
π = 3.14
Required:
Arc length
Solution:
Arc length = θ/360 × 2πr
θ = 180° (half of a circle = 180°)
Plug in the values into the formula
Arc length = 180/360 × 2 × 3.14 × 9
Arc length = ½ × 56.52
Arc length = 28.26 units
Since we know the degrees of the circle is 360, add all of the pieces together and set equal to 360
Solving you get x = 15.
When plugging 15 back into each expression we get 90, 160, and 110.
This means the triangle sides are all different so the triangle is scalene.
Answer:
Option C
Step-by-step explanation:
To test a graph whether it represents a function or relation we conduct a vertical line graph.
If the vertical line intersect the graph at two different points, graph represents a relation only.
By analyzing the given graph with the vertical line test,
Since, a vertical line (x = -4) intersect the graph at two points (y = -1 and y = 5),
Given graph represents a relation only.
Option C is the answer.
Answer:
Increases
Step-by-step explanation:
Increasing interval goes up and up gradually. So now as x goes to the right, y should go up too. This increases...
