Y=10,000(0.97)x predict purchasing power of $10,000 ten years later

Maksim231197 [3]

Answer:

It will be $7602.3

Step-by-step explanation:

The equation $y = 10000(0.97)^{x}$ gives the purchasing power of $10000 after x years.

Therefore, the sum of money $10000 will value $10000(0.97)^{x}$ after x number of years.

Now, after 9 years i.e. x = 9 years, the sum value of $10000 will become $y = 10000(0.97)^{9} = 10000 \times 0.76023 = 7602.3$ dollars. ( Answer )

Step-by-step explanation:

Tan Ф = opposite/adjacent = 170/90 = 1.89

Ф = tan⁻¹ 1.89 = 62.1°

tan Ф = x/207

tan 62.1° x 207 = x

1.89 x 207 = 391.23

allsm [11]

21 students sleep for 9 hours each night

<em><u>Solution:</u></em>

Given that, Mr.Lee wants to survey 20 of the 210 students in seventh grade about the hours they sleep each night

He finds 2 of the 20 students surveyed sleep for 9 hours each night

Therefore, 2 out of 20 students sleep for 9 hours each night

Find out the percentage of 2 out of 20

$\rightarrow \frac{2}{20} \times 100 = 10 \%$

Thus 10 % of 210 students sleep for 9 hours each night

Find out 10 % of 210

$\rightarrow 10\% \text{ of } 210\\\\\rightarrow 10 \% \times 210\\\\\rightarrow \frac{10}{100} \times 210\\\\\rightarrow 21$

Thus 21 students sleep for 9 hours each night
