A function is defined by f(0)=1 and f(n)=f(n-1)+n+1. Find f(5)

topjm [15]

Answer:

f(5) = 21

Step-by-step explanation:

Given:

$f(0)=1$

$f(n)=f(n-1)+n+1$

$\implies f(1)=f(0)+1+1=1 + 1 + 1=3$

$\implies f(2)=f(1)+2+1=3 + 2 + 1=6$

$\implies f(3)=f(2)+3+1=6+3+1=10$

$\implies f(4)=f(3)+4+1=10+4+1=15$

$\implies f(5)=f(4)+5+1=15+5+1=21$

Select whether the equation has a solution or not.

vredina [299]

Answer: The equation has a solution .

Step-by-step explanation:

Since we have given that

$\sqrt{x+1}=7-2\sqrt{x}$

Squaring on both the sides, we get that,

$x+1=(7-2\sqrt{x})^2\\\\x+1=49+4x-28\sqrt{x}\\\\3x+48-28\sqrt{x}=0$

Let $\sqrt{x}=y\implies x=y^2$

So, our equation becomes,

$3y^2-28y+48=0\\\\y=\dfrac{14}{3}\pm \dfrac{2\sqrt{13}}{3}\\\\\sqrt{x}=\dfrac{14}{3}\pm \dfrac{2\sqrt{13}}{3}\\\\x=(\dfrac{14}{3}\pm \dfrac{2\sqrt{13}}{3})^2$

So, $x=\dfrac{248}{9}\pm \dfrac{56\sqrt{13}}{9}$

Hence, the equation has a solution .
