Peter put $8,000 into a savings account that pays 6% interest, compounded continuously. After five years, Peter will have $ 8,001.35 10,798.53 21,744.00 160,634.32 in the account.Hint: Use the formula A = Pert, where A is the amount after t years, P is the amount invested, r is the rate of interest, t is the time period, and e = 2.718. Use a calculator to compute your answer

Answers

We have to calculate the amount of money Peter will have in his account after 5 years. Formula for the amount after t years with interest compounded continuously : A = P * e^(r t ). We know that r = 0.06; t = 5; e = 2.71 and P = $8,000. A = 8,000 * 2.718^( 0.06 * 5 ) = 8,000 * 2,718^( 0.3 ) = 8,000 * 1.3488158 = 10,798.53. Answer: B. $10,798.53.

Brooke has set up 70 chairs in equal rows for the class talent show.But,there is not room for more than 20 rows. What are the possible number of rows that brooke could set up?

Answers

She can not fit more than twenty rows in the class so anything equal to twenty or less (not including zero or negative numbers) would be fine. We don't have a limit for how many chairs in a row so I'm answering assuming that is not a problem so 20,19,18,17,16,15,14,13,12,11,10,9,8,7,6,5,4,3,2, or 1 row(s) would be possible

In aboard game you determine the number of spaces you msy move by spinning a spinner and rolling a die. The spinner has three regions: half of the spinner is marked"5" and the other half is equally divided between "10" and "20". The six faces of the die show 0,0,1,2,3,and 4 spots. When its your turn, you spin and roll, adding the numbers together to determine how far you may movefind the mean and standard deviation of the spiner results after you create a probability model for the outcome on the spinner

Write an equation of the line and interpret the slope.

Answers

The equation of a line can be written using the slope-intercept form, y = mx + b. The slope represents the rate of change between two variables.

To write the equation of a line, we typically use the slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept. The slope represents the rate of change between two variables. If the slope is positive, it indicates a positive correlation, and if the slope is negative, it indicates a negative correlation. A slope of zero indicates a horizontal line.

For example, if we have an equation y = 2x + 3, the slope is 2. This means that for every unit increase in x, the corresponding value of y will increase by 2 units. In other words, the line is getting steeper as we move right.

Slope = y-y/x-x
= (0-3)/(0-2)
= -3/-2
=3/2

It crosses the y axis at 0 so b = 0

y = mx + b
y = 3/2x + 0
In other words,

y = 3/2x

Good luck!

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. Let m represent the number of magazines and b represent the number of books.

Answers

Number of magazines = m
Number of books = b

The cost of one magazine = $3.95
The cost of one book = $8.95

3.95m + 8.95b = 47.65

Answer: is c. 3.95m+8.95b=47.65
