Hal is asked to write an exponential function to represent the value of a $10,000 investment decreasing at 2% annually. What multiplicative rate of change should Hal use in his function?

Answers

Answer 1

Answer: For exponential growth or decrease there is a general formula given:

P(t) = P(0) [exp(rt)]where,P(t) is the investment remaining at time t,P(0) is the investment at time 0, initial investment andr is the exponential rate of decrease.

10,000 * 0.02 = 200
10,000 - 200 = 9,800 value after year 1

P(1) = P(0) [exp (rt)]
9,800 = 10,000 (0.98)^1

r = loge (0.98) = ln (0.98) = -0.0202

P(t) = P(0)[exp(-0.0202t)]

Answer 2

Answer:

Answer: 0.98

Tell which measure of central tendency best describes the data. Time spent on Internet (min/day): 75 38 43 120 65 48 52 A. Mean B. Median C. Mode

Answers

Answer:

B. Median

Step-by-step explanation:

We have been given data about time spent on Internet (min/day). We are asked to determine the best measure of central tendency for the given data.

Data: 75, 38, 43, 120, 65, 48, 52,

We can see that our given data has a very large value outlier (120), so it will increase the mean.

There is no mode for the given data set as no value repeats.

We know that median is best measure for data set with large valued outliers because median is not affected by outliers.

Therefore, option B is the correct choice.

The measure of central tendency that best describes the data is B. Median.

Which measure of central tendency best describes the data on time spent on the Internet?

Mean:

= (75 + 38 + 43 + 120 + 65 + 48 + 52) / 7

= 69.86

Median:

We arrange data in ascending order: 38, 43, 48, 52, 65, 75, 120. Since there are seven values, the median is the middle value: 52

Mode: There is no value that appears more than once in the data set.

Therefore, the measure of central tendency that best describes the data is B. Median.

Victor borrowed money at 5.25 percent simple annual interest. At the end of the year, the interest on the loan is $255.94. What was the amount of the loan?

Answers

The amount of the loan was $4,875.24

Given:
interest = 255.94
rate = 5.25%
term = 1 year

simple annual interest = principal * interest rate * term

principal = simple annual interest / (interest rate * term)
principal = 255.95 / (5.25% * 1yr)
principal = 255.95 / 0.0525
principal = 4,875.24

S.I. = 4,875.24 * 5.25% * 1yr
S.I. = 255.95

Which equations have the same solution as p−3=5?Hint: There are 3 equations

3p=30
3 p is equal to 30

p+2=10
p plus 2 is equal to 10

p8=1
p over 8 is equal to 1

p+7=16
p plus 7 is equal to 16

4p=32

Answers

Answer:

p + 2 = 10

$(p)/(8) =1$

4p = 32

Step-by-step explanation:

p - 3 = 5

p - 3 + 3 = 5 + 3

p = 8

3p = 30

3p ÷ 3 = 30 ÷ 3

p = 10

10 ≠ 8

p + 2 = 10

p + 2 - 2 = 10 - 2

p = 8

8 = 8

$(p)/(8) =1$

$8((p)/(8)) =8(1)$

8 = 8

p = 8

p + 7 = 16

p + 7 - 7 = 16 - 7

p = 9

9 ≠ 8

4p = 32

4p ÷ 4 = 32 ÷ 4

p = 8

8 = 8
