mr. and mrs. boyce bought a house for 96000 in 1995. real estate values in their area increase approximately 4% each year. what was the value of the house in 2007?
The Boyce's house bought for $96,000 in 1995, increased approximately 4% yearly. By applying the compound interest formula, the house's value in 2007 would be approximately $139,254.09.
Explanation:We need to use the compound interest formula to calculate the value of Boyce's house in 2007 because the house price increase is compounded annually. The formula is P(1 + r/n)^(nt). Here, P is the initial amount (i.e., the original house price), r is the annual interest rate (the rate of increase in house value), and n is the number of times interest is compounded yearly. T is the number of years the money is invested.
However, as we deal with annual compounding, the formula simplifies to P(1 + r)^t. In this case, P = $96,000, r = 4% or 0.04, and t = 2007 -1995 = 12 years.
Inserting these values, we get 96000(1 + 0.04)^12 = $139,254.09 (rounded to the nearest cent).
So, according to the 4% annual increase rate, Boyce's house would be worth approximately $139,254.09 in 2007.

Vanessa deposited money into a bank account that earned 1.25% simple interest each year. After 1/2 year, she had earned $5.00 in interest on the account. If no other money was deposited into or withdrawn from the account, how much was her initial deposit? Uhh... I was just testing...oops
so the answer is 800. I guarantee you this will be the answer I promise
Final answer:
Vanessa's initial deposit in the bank, earning 1.25% simple interest per year, was $800. This is calculated using the simple interest formula, rearranged to solve for the principal based on the $5 interest earned in half a year.
Explanation:
To find Vanessa's initial deposit, we use the simple interest formula, which is Interest = Principal × Rate × Time. Given Vanessa earned $5.00 in interest in half a year (0.5 years) at a rate of 1.25% per annum, we can rearrange the formula to solve for the principal (initial deposit).
Using the given information: $5 = Principal × 0.0125 × 0.5, we can solve for the Principal as follows:
$5 = Principal × 0.00625
Principal = $5 ÷ 0.00625
Principal = $800
Therefore, Vanessa's initial deposit was $800.

Lily just paid off a $400 loan. She had to pay $60 in interest at a simple annual interest rate of 5%. How many years did Lily have this loan?
A. 2
B. 3
C. 4.5
D. 5
Answer: The correct option is (B) 3.
Step-by-step explanation: Given that Lily just paid off a $400 loan. She had to pay $60 in interest at a simple annual interest rate of 5%.
We are to find the number of years for which Lily had this loan.
Let n be the required number of years.
Also, P = $400, S.I. = $60 and r% = 5%.
Therefore, by the formula of simple interest, we have
[tex]S.I.=\dfrac{Prn}{100}\\\\\\\Rightarrow 60=\dfrac{400\times5\times n}{100}\\\\\\\Rightarrow n=\dfrac{60}{20}\\\\\\\Rightarrow n=3.[/tex]
Thus, the required number of years is 3.
Option (B) is CORRECT.
Which fraction shows a correct way to set up the slope formula for the line that passes through the points (3,7) and (5,7)?
The slope of a line through the points (3,7) and (5,7) is 0, indicating a horizontal line.
To calculate the slope of a line passing through two points, you can use the formula m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points. In this case, the points are (3,7) and (5,7). Using the slope formula, we get:
m = (7 - 7) / (5 - 3) = 0 / 2 = 0
So, the slope of the line that passes through these points is 0, which means the line is horizontal.

A new law requires that 12% of an individual's income be invested in the stock market. Your accounts show that you need to put $420 in the stock market this year. How much did you earn this year.
A $5,040 B $350 C $504** D $3,500
The problem can be solved by setting up the equation 0.12x = $420, where 'x' stands for your total income. Dividing both sides of the equation by 0.12 gives x = $3500 which is the total annual income. Thus, you earned $3,500 this year.
Explanation:To solve this mathematical problem, you can set up an equation that represents the problem context. You know that 12% of your whole year's income equals $420. So if 'x' represents your total income, the equation becomes 0.12x = $420. To solve for 'x' (your total income), you would divide both sides of the equation by 0.12.
So, x = $420 ÷ 0.12. When you perform this calculation, you'll find that 'x' equals $3,500. Therefore, you earned $3,500 this year.
The answer to the problem is D. $3,500.

Suppose f(π/3) = 3 and f '(π/3) = −7,
and let
g(x) = f(x) sin x
and
h(x) = (cos x)/f(x).
Find the h'(x)
To find h'(x), differentiate the function h(x) = (cos x)/f(x) using the product rule.
Explanation:To find h'(x), we need to differentiate the function h(x) = (cos x)/f(x).
First, let's find the derivative of cos x, which is -sin x.
Next, we need to find the derivative of f(x). Since f(π/3) = 3 and f '(π/3) = −7, we know the slope of the tangent line at x = π/3 is -7.
Using the product rule, we can now differentiate h(x) = (cos x)/f(x) as follows:
h'(x) = [f(x)(-sin x) - cos x(f '(x))]/[f(x)]^2

Suppose that a drop of mist is a perfect sphere and that, through condensation, the drop picks up moisture at a rate proportional to its surface area.
Let V be the volume of the sphere & S be the surface area.
According to the question,
dV/dt = kS
Since,
V = 4/3πr³
dV/dt = 4πr²dr/dt
S = 4πr²
Putting these values to the above expression,

At 9:00 on Saturday morning, two bicyclists heading in opposite directions pass each other on a bicycle path.The bicyclist heading north is riding 4 km/hour faster than the bicyclist heading south. At 10:15, they are 40 km apart. Find the two bicyclists’ rates.
The speed of Bicyclist A (heading north) is 16 km/h.
The speed of Bicyclist B (heading south) is 11 km/h.
Given:
- Let x be the speed of bicyclist A (heading north).
- Let y be the speed of bicyclist B (heading south).
- Bicyclist A is 5 km/h faster than Bicyclist B, so [tex]\(x = y + 5\)[/tex] (Equation 1).
- Time from 9:00 to 10:45 is 1.75 hours.
- The total distance covered by both bicyclists during this time is 47.25 km.
From the equation for time and distance, we have:
[tex]\[ x \times 1.75 + y \times 1.75 = 47.25 \][/tex]
Substituting Equation 1 into this equation:
[tex]\[ (y + 5) \times 1.75 + y \times 1.75 = 47.25 \]\[ 1.75y + 8.75 + 1.75y = 47.25 \]\[ 3.5y + 8.75 = 47.25 \]\[ 3.5y = 38.5 \]\[ y = \frac{38.5}{3.5} \]\[ y = 11 \text{ km/h} \][/tex]
Substituting the value of y back into Equation 1:
[tex]\[ x = 11 + 5 \]\[ x = 16 \text{ km/h} \][/tex]
Thus, the correct answer is:
- The speed of Bicyclist A (heading north) is 16 km/h.
- The speed of Bicyclist B (heading south) is 11 km/h.

A basketball team averages 98 points in its first three games.How many points must it score in the next game in order to have 100 point average overall?
The basketball team must score 106 points in the next game to have a 100-point average overall.
To determine how many points the basketball team must score in the next game to have a 100-point average overall, we need to consider the total points scored in the first three games and the desired average.
The team has already played three games and has an average of 98 points. To find the total points scored in these three games, we multiply the average by the number of games:
Total points in the first three games = 98 points/game * 3 games = 294 points.
To have a 100-point average overall, the team needs to score a total of 100 points per game multiplied by the total number of games played, including the next game.
Let's represent the number of points needed in the next game as "x."
(294 points + x points) / (3 games + 1 game) = 100 points/game.
Simplifying the equation:
(294 + x) / 4 = 100.
Cross-multiplying and solving for "x":
294 + x = 400.
x = 400 - 294.
x = 106.
