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.
Answer:
M= the slope or the gradient
B= the y-intercept
y= the output value
x= the input value
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
First we need to find the radius
r =d/2 = 15.8/2 = 7.9 cm
The area of a circle is given by
A = pi r^2
= pi ( 7.9) ^2
=62.41 pi
Using 3.14 for pi
195.9674
To the nearest hundredth
195.97
Using the pi button
196.0667975
To the nearest hundredth
196.07
Answer: OPTION C.
Step-by-step explanation:
In order to solve the given exercise, you can follow these steps:
1. Given the following function f(x):
You must substitute 
into the function f(x). Then:
2. Evaluating, you get:
3. Now, the next step is to substitute 
into the function g(x):
4. Finally, evaluating, you get the following result:
You can identify that it matches with the Option C.
Firstly , we can draw diagram
we can see that
adjacent = 850
opposite =250
so, we can use tan formula
16.38
so,
angle of depression is 16.38 degree........Answer
