Suppose you put $1000 in an account earning 5.5% interest compounded continuously. How much will be in the account after four years?
a. $941
b. $1,246
c. $1,057
d. $1,839
Answer: The correct answer will be $1,220 in the account after four years.
Step-by-step explanation: For this problem we will use the "Simple Interest" equation to find the amount of interest you will earn after 4 years.
First, convert 5.5% to a decimal, 0.055.
I, interest = 1000 x 0.055 x 4
I = $220
Now add the interest to the total amount of money originally in the account.
1000 + 220 = $1,220
Final answer:
The amount in the account after four years, with continuous compound interest at a rate of 5.5%, is approximately $1246. Therefore, after four years, the amount in the account will be closest to option (b) $1,246.
Explanation:
To calculate the amount in the account after four years, we can use the formula for continuous compound interest: A = P [tex]e^{(rt)}[/tex], where A is the final amount, P is the initial principal, e is the mathematical constant approximately equal to 2.71828, r is the interest rate, and t is the time in years.
In this case, P = $1000, r = 5.5% = 0.055, and t = 4. Plugging these values into the formula, we have:
A = $1000 × [tex]e^{(0.055 \times 4)}[/tex]
A = $1000 × [tex]e^{0.22[/tex]
A ≈ $1000 × 1.246
Therefore, the amount in the account after four years is approximately $1246.

Keep working and you will earn half credit for correctly solved problem.
Final answer:
Susie was 20 meters behind Andy when he reached the finish line in the 100-meter race.
Explanation:
To determine how many meters Susie was behind Andy at the moment Andy reached the finish line during the 100-meter race, let's consider the information given:
Andy finished the race.
Blaise was 10 meters behind Andy at that moment.
Susie was 10 meters behind Blaise when Blaise finished the race.
When Blaise reached the finish line, Andy would have already finished since Blaise was behind by 10 meters. However, at the moment Andy finished, Susie was also behind Blaise, who was 10 meters from finishing. Hence, Susie was 10 meters (the distance Blaise was behind Andy) + 10 meters (the distance Susie was behind Blaise at her finish) = 20 meters behind Andy when he finished the race.
In conclusion, Susie was 20 meters behind Andy when Andy reached the finish line.

Niles and Bob sailed at the same time for the same length of time. Niles' sailboat traveled 36 miles at a speed of 6 mph, while Bob's motorboat traveled 96 miles at a speed of 16 mph. For how long were Niles and Bob traveling?
Answer:
Niles and Bob were traveling for 6 hours.
Step-by-step explanation:
The speed or rate at which an object is moving can be computed using the formula:
[tex]s=\frac{d}{t}[/tex]
Here:
s = speed
d = distance traveled
t = time taken
It is provided that Niles and Bob sailed at the same time for the same length of time.
Speed of Niles sailboat is, s₁ = 6 mph.
Distance traveled by Niles' sailboat is, d₁ = 36 miles.
Speed of Bob's sailboat is, s₂ = 16 mph.
Distance traveled by Bob's sailboat is, d₂ = 96 miles.
It took both Niles and Bob the same time to travel the respective distance.
Compute the time it took Niles to travel 36 miles at 6 mph speed as follows:
[tex]t_{1}=\frac{d_{1}}{s_{1}}[/tex]
[tex]=\frac{36}{6}\\=6[/tex]
It took Niles 6 hours to travel 36 miles at 6 mph speed.
Compute the time it took Bob to travel 96 miles at 16 mph speed as follows:
[tex]t_{2}=\frac{d_{2}}{s_{2}}[/tex]
[tex]=\frac{96}{16}\\=6[/tex]
It took Bob 6 hours to travel 96 miles at 16 mph speed.
Thus, Niles and Bob were traveling for 6 hours.
Suppose that the number of cars manufactured at an automobile plant varies jointly as the number of workers and the time they work. If 160 workers can produce 32 cars in 2 hours, find the number of cars that 220 workers can produce in 3 hours.
Answer:
They'll build 66 cars in those conditions.
Step-by-step explanation:
In this case we can use a compounded rule of three to solve the problem. We need to set it up as shown bellow:
160 workers -> 32 cars -> 2 hours
220 workers -> x cars -> 3 hours
If the number of workers rise, then we expect the number of cars to rise aswel, so they're directly proportional. If the number of hours worked increase we can expect the number of cars to increase aswell, so they're directly proportional. We can now set the fractions:
(160*2)/(220*3) = 32/x
320/660 = 32/x
x = (32*660/320) = 66 cars
They'll build 66 cars in those conditions.
Final answer:
To find the number of cars that 220 workers can produce in 3 hours, we can use the joint variation equation and the given information. By solving for the constant of variation, we can substitute the new values to find the answer.
Explanation:
To solve this problem, we can set up a joint variation equation:
cars = k * workers * time
Given that 160 workers can produce 32 cars in 2 hours, we can substitute these values into the equation:
32 = k * 160 * 2
Solving for k, we find that k = 0.1.
Now, we can use this value of k to find the number of cars that 220 workers can produce in 3 hours:
cars = 0.1 * 220 * 3
cars = 66
Therefore, 220 workers can produce 66 cars in 3 hours.

Let's break this down:
Saying "y=", is just like saying "0=", so we can say that;
0=4x-9
We need to isolate the variable, and to do that we should add 9 to both sides and cancel it out.

Tristan has some dimes and some quarters. He has at least 20 coins worth at most $4.25 combined. If Tristan has 10 dimes, determine the maximum number of quarters that he could have. If there are no possible solutions, submit an empty answer.
Answer:
The maximum number of quarters that he could have is 13
Step-by-step explanation:
Let x represent the number of quarters he could have. If he has 10 dimes and has at least 20 coins, then
→ x + 10 >= 20
→ x >= 10 (1)
His coins worth at most $4.25. Also, it is known that 1 dollar is equal to 100 cents, 1 dime is equal to 10 cents and 1 quarter is equal to 25 cents.
→ (x * 25) + (10 * 10) <= (4.25 * 100)
→ 25x + 100 <= 425
→ 25x <= 325
→ x <= 13 (2)
If we combine the equation 1 and 2:
10 <= x <= 13
The maximum value of x is 13

work out the area of triangle give your answer to 1 decimal place
Given:
Given that the triangle.
Let the length of the side a be 10 cm.
Let the length of the side b be 13 cm.
Let the measure of ∠C is 105°
We need to determine the area of the triangle.
Area of the triangle:
The area of the triangle can be determined using the formula,
[tex]A=\frac{1}{2} a b \ sin \ c[/tex]
Substituting a = 10, b = 13 and ∠C = 105°, we get;
[tex]A=\frac{1}{2}(10)(13) \ sin \ 105[/tex]
Simplifying, we get;
[tex]A=\frac{1}{2}(10)(13)(0.966)[/tex]
[tex]A=\frac{1}{2}(125.58)[/tex]
[tex]A=62.79 \ cm^2[/tex]
Rounding off to 1 decimal place, we have;
[tex]A=62.8 \ cm^2[/tex]
Thus, the area of the triangle is 62.8 cm²
The area of the triangle is 65 square centimeters when rounded to one decimal place.
To find the area of a triangle, you can use the formula:
[tex]Area = (\frac{1}{2} ) \times base \times height[/tex]
In this case, you have a base of 13 cm and a height of 10 cm. Plug these values into the formula:
[tex]Area =(\frac{1}{2} ) \times 13 cm \times 10 cm[/tex]
[tex]Area = (\frac{1}{2}) \times 130 cm^2[/tex]
Now, calculate the area:
