Answers

Answer:

2.3%

Step-by-step explanation:

18000 = 15000( 1 + i)^8

Divide both sides by 15000

1.2 = (1 + i)^8

Take both sides to the 1/8 power

1.2^(1/8) = 1 + i

1.023051875220463 = 1 + i

Subtract 1 from both sides

i = 0.023051875220463

Which of the following functions best represents the graph? A. f(x) = x3 + 2x2 − 4x − 8

B. f(x) = x3 + 4x2 − x − 4

C. f(x) = x3 + x2 − 9x − 9

D. f(x) = x3 + 3x2 − 3x − 9

Answers

Answer:

Option: C is the correct answer.

$f(x)=x^3+x^2-9x-9$

Step-by-step explanation:

Clearly from the graph we could see that:

3 and -3 are zeros of the function f(x).

since the graph crosses these two points on the x-axis.

i.e. when x=3 or -3 ⇒ f(x)=0

Now when we put x=3 in each of the equation we see that:

$f(x)=x^3+2x^2-4x-8$

when x=3

$f(x)=3^3+2* 3^2-4* 3-8\n\nf(x)=27+18-12-8\n\nf(x)=25\neq0$

Hence, option A is incorrect.

$f(x)=x^3+4x^2-x-4$

when x=3

$f(x)=27+36-3-4\n\nf(x)=56\neq0$

Hence, option B is incorrect.

$f(x)=x^3+3x^2-3x-9$

when x=3

$f(x)=27+27-9-9\n\nf(x)=36\neq0$

Hence, option D is incorrect.

Hence all the three options are discarded.

Hence, option C is the correct answer.

The function best represents the graph is:

$f(x)=x^3+x^2-9x-9$

The time, in seconds, that it takes a pendulum to swing back and forth is modeled by the equation below. f (l) = 2 pi StartRoot StartFraction l Over 32 EndFraction EndRoot, where l is the length of the pendulum in feet What is the approximate length of a pendulum that takes 2.4 pi seconds to swing back and forth?

Answers

Answer:

46.08 feet.

Step-by-step explanation:

Given that, for length, $l$ feet, the time period, $f(l)$ , of the pendulum is

$f(l)=2\pi\sqrt{(l)/(32)}$ .

As the time period equals the time taken by the pendulum in one back and forth motion, so, actually, the given $2.4\pi$ seconds to swing back and forth is the time period.

Let $l_0$ feet be the length of the pendulum for the time period $2.4\pi$ seconds, so

$f(l_0)=2.4\pi$

$\Rightarrow 2\pi\sqrt{(l_0)/(32)}=2.4\pi$

$\Rightarrow \sqrt{(l_))/(32)}=1.2$

$\Rightarrow (l_0)/(32)=(1.2)^2$ [squaring on both the sides]

$\Rightarrow l_0=1.44*32$

$\Rightarrow l_0=46.08$

Hence, the approximate length of a pendulum that takes $2.4 \pi$ seconds to swing back and forth is 46.08 feet.
