Suppose an investment of $10,000 doubles in value every 13 years. How much is the investment worth after 52 years? After 65 years?

A: $80,000; $100,000

B: $160,000; $320,000

C: $520,000; $650,000

Answers

Answer:

Step-by-step explanation:

The answer is actually B. $160,000; $320,000

The reason for this is because -

$10,000 is the constant, so let a= 10,000.

The investment doubles every 13 years, so let b=2.

Let x= the number of 13-year periods.

Final answer:

The value of a $10,000 investment doubling every 13 years will be $160,000 after 52 years and $320,000 after 65 years.

Explanation:

To calculate the value of an investment that doubles every 13 years, you can determine the number of times the investment will double over a given period. In this case, after 52 years, the investment will have doubled 4 times (since 52 divided by 13 is 4), and after 65 years, it will have doubled 5 times (since 65 divided by 13 is 5).

The formula for the future value of an investment that doubles is: Future Value = Present Value × (2^number of doublings).

After 52 years, the investment's worth would be calculated as follows:

$10,000 × (2^4) = $10,000 × 16 = $160,000

After 65 years, the investment's worth would be:

$10,000 × (2^5) = $10,000 × 32 = $320,000

Therefore, the correct answers are $160,000 after 52 years and $320,000 after 65 years, which corresponds to choice B.

The function H(t) = −16t2 + 48t + 12 shows the height H(t), in feet, of a cannon ball after t seconds. A second cannon ball moves in the air along a path represented by g(t) = 10 + 15.2t, where g(t) is the height, in feet, of the object from the ground at time t seconds.

Part A: Create a table using integers 0 through 3 for the 2 functions. Between what 2 seconds is the solution to H(t) = g(t) located? How do you know? (6 points)

Part B: Explain what the solution from Part A means in the context of the problem. (4 points)

Answers

Part A
t           0     1      2    3
H(t)    12   44    44     42
g(t)     10   25    40     56
Set H(t) = g(t) yields 16t^2 -32t -2 which shows its zeroes or points of intersections are at 0.6 and 2.1 seconds
Part B
H(t) = g(t) intersect at (x,y) points (0.6 secs, 9.1 feet) and (2.1 secs, 42.1 feet)
H(t) is a parabola that opens downward which shows the cannonball arches upwards then falls downward.
g(t) is a straight linear line which slopes positive upwards and intersects G(t) in two places.

Answer with explanation:

We are given a function H(t) that represents the height of a cannon ball after t seconds as:

[tex]H(t)=-16t^2+48t+12[/tex]

and a second cannon ball is represented by the function g(t) as:

[tex]g(t)=10+15.2t[/tex]

PART A:

t 0 1 2 3

H(t) 12 44 44 12

g(t) 15.2 25.2 40.4 55.6

Hence, between t= 2 seconds and t=3 seconds the ball will meet

such that H(t)=g(t)

Since, we know that the Height H(t) decreases from 44 feet to 12 feet between t=2 to t=3 seconds.

and height g(t) increases from 40.4 feet to 55.6 feet between t=2 to t=3 seconds.

Hence, the two cannon balls will definitely meet between t=2 to t=3 seconds.

and the time at which they meet is calculated by solving:

[tex]H(t)=g(t)\\\\i.e.\\\\\\-16t^2+48t+12=10+15.2t\\\\\\i.e.\\\\\\16t^2-32.8t-2=0\\\\\\i.e.\\\\\\t=-0.059\ and\ t=2.109[/tex]

As t can't be negative.

Hence, we get:

t=2.109 seconds

PART B:

The solution from PART A means that the one of the ball first reach the highest point at 44 feet and then returns back to the initial position and hence follows a parabolic path while the second cannon ball reach a greater height with the increase in time and hence in this phenomena the two balls will definitely meet.

The volume of a rectangular prism can be computed using the formula V = lwh. What is the height of a prism that has a volume of 2376 cubic centimeters, a length of 18 centimeters, and a width of 11 centimeters?

A. 24 cm
B. 726 cm
C. 16 cm
D. 12 cm

Answers

I believe it is D because V= lwh. The length is 18 and the W= 18. the V is 2376. When solving this you replace it with the numbers so it would be 2376=18x11xh and then it would be 2376=198xh and it would equal to 2376=198x. When you get that answer you divide by 198 on both sides and get 12.

What is the image of (5,-1) under same translation?

Answers

P(-2, 3) to P'(-6, -4)
translate 4 units left and 7 units down

so (5, -1) with 4 units left and 7 units down should be (1, -8)
answer is B. (1, -8)

The image of point (5, -1) under the same translation that maps point P to P' is (1, -8). This translation vector is obtained by subtracting the coordinates of P from P'.

To find the image of point (5, -1) under the same translation T that maps point P to P', we can calculate the vector that represents the translation from P to P' and then apply the same translation to point (5, -1).

The translation vector is given by:

Translation vector = P' - P = (-6, -4) - (-2, 3) = (-4, -7)

Now, to find the image of point (5, -1) under the same translation, we simply add this translation vector to (5, -1):

Image of (5, -1) = (5, -1) + (-4, -7) = (5 - 4, -1 - 7) = (1, -8)

So, the image of point (5, -1) under the translation T is (1, -8). Therefore, the correct answer is B. (1, -8).

How to calculate standard deviation given mean and sample size?

Answers

In addition to mean and sample size you will need the individual scores.

The formula for standard deviation is:

S^2 = E(X-M)^2/N-1

Here's an example:
Data set: 4,4,3,1
Mean: 3
Sample size: 4

First, put the individual scores one after the other and subtract the mean from it.
4 - 3 = 1
4 - 3 = 1
3 - 3 = 0
1 - 3 = -2

Second, square the answers you got from step 1.
1^2 = 1
1^2 = 1
0^2 = 0
-2^2 = 4
Third, plug the values from step 2 into the formula.

S^2 = (1+1+0+4)/(4-1) = 6/3 = 2

Standard deviation = 2

A total of 900 tickets were sold for a game for a total of $1,150. if adult tickets sold for $2.00 and children's tickets sold for $1.00, how many of each kind of ticket were sold?

Answers

575 adult tickets and 325 child tickets were sold.

adult tickets = a
child tickets = c

a + c = 900
2a + c = 1150

Subtract c from the equation on top to get a = 900 - c
Substitute this value into the second equation 2(900 - c) = 1150
Simplify to make 1800 - 2c = 1150
Add 2c to both sides
1800 = 1150 + 2c
Subtract 1150 from each side
2c = 650
Divide by 2 so that c = 325. Therefore, 325 child tickets were sold.

To find the number of adult tickets, subtract 325 from 900
The remaining number (a = 900 - 325 = 575) is how many adult tickets were sold. 575 adult tickets were sold.

Joan has a credit card that uses the previous balance method. The opening balance of one of her 30-day billing cycles was $6390, but that was her balance for only the first 3 days of the billing cycle, because she then paid off her entire balance and didn't make any new purchases. If her credit card's APR is 17%, which of these expressions could be used to calculate the amount Joan was charged in interest for the billing cycle?

Answers

Answer:

Step-by-step explanation:

(0.17/365 x30)(6390)

The expression that represents the amount Joan was charged in interest for the billing cycle is $26.84.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To calculate the amount Joan was charged in interest for the billing cycle using the previous balance method, we need to find the average daily balance for the billing cycle, which is calculated as the sum of the daily balances divided by the number of days in the billing cycle.

The daily balance is the balance at the end of each day, and it is calculated by adding new purchases and subtracting payments and credits from the previous day's balance.

In this case,

Joan had a balance of $6390 for the first 3 days of the billing cycle, so her average daily balance for the billing cycle can be calculated as:

((3 x 6390) + (27 x 0)) / 30

= 1917

This means that her average daily balance for the billing cycle was $1917.

To calculate the amount of interest Joan was charged for the billing cycle, we can use the following expression:

Interest = Average Daily Balance x Daily Interest Rate x Number of Days in Billing Cycle

The daily interest rate is calculated as the APR divided by 365 since there are 365 days in a year. In this case, the daily interest rate is:

0.17 / 365

= 0.000465753

So, the expression that can be used to calculate the amount of interest Joan was charged for the billing cycle is:

Interest = 1917 x 0.000465753 x 30

= $26.84 (rounded to the nearest cent)

Therefore,

The expression that represents the amount Joan was charged in interest for the billing cycle is $26.84.
