Answer with Step-by-step explanation:
We are given that
for
We have to prove that for all n equal and greater than 1
proof: Let P(n)= for all n equals to and greater than 1
We prove that for all n there exists Z,if n greater and equals to zero
Base case : The base case is n=1
Substitute n=1 then we get
P(1)=-3(1)+5=2
This is true for n=1
Induction step : suppose that P(n) is true for n=k where k greater than 1
Then P(k)=-3k+5
Now, we shall prove that for n=k+1, P(n) is true for n=k+1
P(k+1)=-3(k+1)+5
P(k+1)=-3k-3+5=-3k+5-3
We are given that for n equal to and greater than 2
Therefore, P(n) is true for n=k+1
Hence, P(n)=-3n+5 for all n equal and greater than 1
Answer:
The answer is x=24.
Step-by-step explanation:
This is a one step equation, so it is simple, as shown.
In order to isolate the variable, you need to multiply each side of the equation by the fraction's reciprocal. In this case, it is -4/5.
Thus, x= -30 x -4/5
All things said, the answer is x=24.

It’s 0.441 just really got to read it right that’s all
You need to find Circumference of each circle so the top is 7cm and the bottom is 5cm
C = pi • diameter
So top is 3.14 • 7 = 21.98
And bottom is 3.14 • 5 = 15.70
Need any more help?
