Final answer:
The value of an investment of $4500 at a 7.25% annual interest rate, compounded continuously, is calculated using the compound interest formula [tex]P = P_0e^{rt}[/tex], where P0 is the initial amount, r is the rate as a decimal, and t is the time in years.
Explanation:
The subject of this question is Mathematics, and it falls under the High School grade level. To find the value of an investment compounded continuously, we use the formula:
[tex]P = P_0e^{rt}[/tex]
Where:
P0 is the initial amount investedr is the annual interest rate (in decimal form)t is the time in yearse is the base of the natural logarithm, approximately equal to 2.71828Given a $4500 investment at a 7.25% annual interest rate, compounded continuously, we can calculate the future value of the investment after t years. Convert the percentage to a decimal by dividing by 100:
r = 7.25 / 100 = 0.0725
So the formula becomes:
[tex]P = $4500e^{0.0725t}[/tex]
Plug in the number of years into 't' to calculate the future value for that specific duration.
After 2, 4, and 6 years of continuous compounding, the investment values are approximately $5198.85, $6014.70, and $6953.85 respectively.
To find the value of the investment after a certain number of years with continuous compounding, we use the formula:
[tex]\[ A = P e^{rt} \][/tex]
Given:
- P = $4500
- r = 7.25% = 0.0725 (as a decimal)
We need to calculate the value of the investment after 2, 4, and 6 years.
(a) For 2 years:
[tex]\( A = 4500 \times e^{0.0725 \times 2} \)\\\( A = 4500 \times e^{0.145} \)\\\( A \approx 4500 \times 1.1553 \)\\\( A \approx \$5198.85 \)[/tex]
(b) For 4 years:
[tex]\( A = 4500 \times e^{0.0725 \times 4} \)\\\( A = 4500 \times e^{0.29} \)\\\( A \approx 4500 \times 1.3366 \)\\\( A \approx \$6014.70 \)[/tex]
(c) For 6 years:
[tex]\( A = 4500 \times e^{0.0725 \times 6} \)\\\(A = 4500 \times e^{0.435} \)\\\(A \approx 4500 \times 1.5453 \)\\\( A \approx \$6953.85 \)[/tex]
So, the values of the investment after 2, 4, and 6 years respectively are approximately:
(a) $5198.85
(b) $6014.70
(c) $6953.85
Complete Question:
If $ 4500 is invested at an interest rate of 7.25% per year, compounded continuously, find the value of the investment after the given number of years. (Round your answers to the nearest cent.)
(a) 2 years
(b) 4 years
(c) 6 years
Are Abel Fields’s actions protected by the First Amendment?
According to a 2012 decision by the US Supreme Court, Abel Fields's actions are protected by the First Amendment.
In the fictitious case study scenario of Abel Fields, he claimed to have received a Purple Heart for wounds suffered in combat, when in fact he had never served in the military. He asserted his claim as a freedom of speech issue.
In a real-life decision by the US Supreme Court, United States v. Alvarez, the the Court struck down the Stolen Valor Act of 2005 (signed into law by President G.W. Bush in 2006). The law had criminalized false statements about having a military medal. By a 6-3 majority, the Supreme Court determined that the Stolen Valor Act was unconstitutional under the First Amendment's protection of free speech.

Given triangle JKL, sin 38 degree equals
Answer:
B. [tex]\text{cos}(52^{\circ})[/tex].
Step-by-step explanation:
We have been given a right triangle. We are asked to complete our given statement.
[tex]\text{sin}(38^{\circ})[/tex] equals ___.
We will use identity [tex]\text{sin}(x)=\text{cos}(90-x)[/tex] to solve our given problem.
[tex]\text{sin}(38^{\circ})=\text{cos}(90^{\circ}-38^{\circ})[/tex]
[tex]\text{sin}(38^{\circ})=\text{cos}(52^{\circ})[/tex]
Therefore, [tex]\text{sin}(38^{\circ})[/tex] equals [tex]\text{cos}(52^{\circ})[/tex].
Chloe draws three parallelograms. In each figure, she measures a pair of angles, as shown. What is a reasonable conjecture for Chloe to make by recognizing a pattern and using inductive reasoning?
a) In a parallelogram, consecutive angles are supplementary.
b) In a parallelogram, all angles are congruent.
c) In a parallelogram, all angles are supplementary.
d) In a parallelogram, consecutive angles are congruent.
The conjecture Chloe can make based on the given information is that in a parallelogram, consecutive angles are congruent.
Explanation:Chloe's conjecture, based on the pattern she observed, would be that in a parallelogram, consecutive angles are congruent. To support this conjecture, we can explain that a parallelogram has opposite sides that are parallel, and therefore, the opposite angles are congruent. Since the consecutive angles are adjacent to these opposite angles, they must also be congruent.

Step-by-step explanation:
Together, teammates pedro and ricky got 2671 base hits last season. pedro had 277 more hits than ricky. how many hits did each player have?
To find out how many hits each player had, we set up a system of equations and solve for the variables. Pedro had 2474 hits and Ricky had 1197 hits.
Explanation:To solve this problem, we need to set up a system of equations. Let's represent the number of hits Pedro had as x and the number of hits Ricky had as y. We are given that their combined hits is 2671, so we can write the equation:
x + y = 2671
Additionally, we are given that Pedro had 277 more hits than Ricky. This can be represented as:
x = y + 277
We can now substitute the second equation into the first and solve for y:
y + 277 + y = 2671
2y = 2394
y = 1197
Now we can substitute the value of y back into the first equation to solve for x:
x + 1197 = 2671
x = 2474
Therefore, Pedro had 2474 hits and Ricky had 1197 hits.
