Answer:

x= 1 and x= -1

Step-by-step explanation:

$5x^{2} +2=7$

(subtract 2 from both sides)

$5x^{2} =5$

(divide by 5 from both sides)

$x^{2} =1$

(take the square root from both sides)

x=±√1

so,

x= 1

and

x= -1

zepelin [54]

Answer:

At the end of the second day, the value of the share is $23.76

Step-by-step explanation:

Maddie bought $22 worth of share

20% increase of $22 share in the first day

= 20/100 × 22

= $4.40

The total value at the end of the $22 + $4.40

= $26.40

On the second day, 10% decrease of $26.40 is

= 10/100 × $26.4

= $2.64

At the end of the second date, the value of the share is $26.40 - $2.64

= $23.76

OleMash [197]

Answer:

1/24

Step-by-step explanation:

13/6x = 52

1/6x = 52/13

1/6x = 4

1 = 4(6x)

1 = 24x

24x = 1

x = 1/24

Find the Maclaurin series for f(x) using the definition of a Maclaurin series. [Assume that f has a power series expansion. Do n

Darina [25.2K]

Recall that for |x| < 1, we have

$\displaystyle \frac1{1-x} = \sum_{n=0}^\infty x^n$

Differentiating both sides gives

$\displaystyle \frac1{(1-x)^2} = \sum_{n=0}^\infty nx^{n-1} = \sum_{n=0}^\infty (n+1)x^n$

and multiplying both sides by 8 gives the series for f(x) :

$f(x)=\displaystyle \frac8{(1-x)^2} = \boxed{8\sum_{n=0}^\infty (n+1)x^n}$

and this converges over the same interval, |x| < 1, so that the radius of convergence is 1.
