Which of the following is not an example of nonverbal communication?

raised eyebrows
a derisive chuckle
rolling eyes
thumbs up

It’d be the second one because you’re making a sound rather than a movement

a. 3.53%

b. $25.58

c. 6.93%

Explanation:

a. We use the RATE formula that is shown in the attachment.

Given that,  

Present value = $25

Future value or Face value = $25 × 2 = $50

PMT = $0

NPER = 20 years

The formula is shown below:  

= Rate(NPER;PMT;-PV;FV;type)  

The present value come in negative  

So, after solving this, the exact rate of return is 3.53%

b. We use the FV formula that is shown in the attachment

Given that

Present value = $25

Rate of interest = 0.23%

NPER = 10 years

PMT = $0

The formula is shown below:

= -FV(Rate;NPER;PMT;PV;type)

After solving this, the future value is $25.58

c. We use the RATE formula that is shown in the attachment.

Given that,  

Present value = $25.58

Future value or Face value = $25 × 2 = $50

PMT = $0

NPER = 10 years

The formula is shown below:  

= Rate(NPER;PMT;-PV;FV;type)  

The present value come in negative  

So, after solving this, the annual rate of return is 6.93%
