Answer:
Step-by-step explanation:
For n Arithmetic Means between two Numbers a & b the formula for xth Arithmetic Mean is:
Aₓ= a+ x(b-a)/(n+1)
Here; n=total means =4
a= 1st number=10
b=20, x= Number of mean
A₁= 10+1(20-10)/(4+1) = 10+10/5 = 10+2 = 12
A₂= 10+2(20-10)/(4+1) = 10+2(10)/5=10+4= 14
Now you can see that common difference is going on d=2 you can easliy 2 further to get A₃ & A₄ which will be 16 and 18 respectively.

Answer:
y = -x +3
Step-by-step explanation:
The 2-point form of the equation of a line is useful when 2 points are given.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (0 -5)/(3 -(-2))(x -(-2)) +5
y = -5/5(x +2) +5
y = -x +3
Answer:
(-2.95,0)
x = -2.95 is the zero of the function.
Step-by-step explanation:
We are given the function:
We have to find the zero of the function.
Zero of function:
- It is the value where the function have a value zero.
- such that
We can find zero of the function in the following manner:
Thus, x = -2.95 is the zero of the function.
