Step-by-step explanation:
Objective: Solving Piecewise Functions
Analyze the info in the graph.
We know that if x=1, the graph will coincide at 5.
If x is greater than 1, the answer will be x squared it answer so any positve interger greater than 1 the answer is that squared.
If x is less than 1, the answer will be double that x.
Let check the answer choices.
A is wrong because x is less than 1 so the answer should be 2(-2)=-4 not 4.
C is Wrong, since 5 is greater than 1, it must be 25 so 5^2=25
D and B are both right, 2 is greater than 1 so 2 squared =4 and Whenever x=1, it will equal 5.
Remember
(x^m)^n=x^(mn)
and
![x^{m/n}=\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=%20x%5E%7Bm%2Fn%7D%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D%20)
(m^(2/3))^(1/2)=m^(2/6)=m^(1/3)
m^(1/3)=∛m
last one (rightmost)
Answer:
B. 7854.0 cm2
The area of a circle is given by A= π 
where r is the radius
So A= π
= 7854.0 cm2
