Answer:
D,E are not functions
Step-by-step explanation:
A function is a relation in which every input has not more than one output.But the output of the inputs may be same.Here in D the input 1 has 4 different outputs as 1,2,3,4.So its not a function.Similarly in E 6 has 2 outputs as 2 and -1.For remaining sets the inputs has only one output.so they are functions.
0.52
Step-by-step explanation:
To round 0.524 to the nearest hundredth consider the thousandths’ value of 0.524, which is 4 and less than 5. Therefore, the hundredths’ value of 0.524 remains 2.
0.524 rounded to the nearest hundredth = 0.52
Answer:
No, it is 45
Step-by-step explanation:
5*9=45
Answer:
c=13 and a=20
Step-by-step explanation:
Here you need to use the Pythagoras theorem :
c²=a² + b²
c = √a² + b²
c = √(12)²+(5)²
c= √144+25
c = √169
c = 13
2) c²=a²+b²
b= √c²-b²
b= √(29)²-(21)²
b = √400
b = 20
In 2 you change your formula just so that it can be easier and just calculate your length straight forward but you can also just do it in the original equation
