Answer:
The correct option is;
D. The function is positive when x > 0
Step-by-step explanation:
The reciprocal parent function is of the form;
Where;
h = The horizontal translation
k = The vertical translation
a = The orientation of the graph
Therefore, whereby we have, h = 0, k = 0. and a = 1, the equation becomes;
Therefore, the value of the function y is positive when x > 0 and is negative when x < 0.
Answer: The length of third side is 15.
Step-by-step explanation:
Alright, lets get started.
Please refer the diagram I have attached.
The perimeter of given triangle is 44.
One side, suppose a is 18.
Second side, suppose b is 11.
Suppose, third side is c.
So the perimeter will be :
Subtracting 29 in both sides
Hence the length of third side is 15. Answer
Hope it will help :)
Answer:
The length of minor arc AB is π ft
Step-by-step explanation:
The formula of the length of an arc in a circle is L = × 2πr, where α is the central angle subtended by the arc, and r is the radius of the circle
∵ The radius of the circle is 4 ft
∴ r = 4
∵ ∠AOB is a central angle subtended by minor arc AB
∵ m∠AOB = 50°
∴ α = 50°
Substitute the values of r and α in the rule above
∵ L = × 2π(4)
∴ L = π
∴ The length of minor arc AB is π ft
