Adeli opened a savings account with an initial deposit of $2000 and will not make any additional deposits or withdrawals the account earns 5% interest compounded annually what is the total amount that adele will have in her account in the end of the 3 years
Answers
The total amount that Adele will have in her account at the end of the 3 years is $2,315.25.
Given that, principal=$2000, rate of interest=5% and time period=3 years.
How to calculate the compound interest?The compound interest formula is used to calculate compound interest, sometimes known as "interest on interest". The formula for compound interest is \(A = P(1 + \frac{r}{100})^{nt}\), where P= principal balance, r= interest rate, n= number of times interest is compounded per time period and t= number of time periods.
Now, A=2000(1+5/100)³
=2000(1+0.05)³
=2000(1.05)³
=$2,315.25
Therefore, the total amount that Adele will have in her account at the end of the 3 years is $2,315.25.

Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in 12 hour. At the airport, they exited the car and walked for 34 hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in 214 hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.Answer the following questions about Kiley’s trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that Kiley is at rest (that is, not moving).In this task, you will write the ratio of miles to hours for each leg of Kiley’s trip. You will then, express the ratio as a decimal number. Next, you will find the unit rate in miles per hour (mph) for each leg of the trip. If your unit rate includes a repeating decimal number, you must indicate which digits repeat (for example, write 0.3¯when the 3 repeats.) A description of each leg is listed below in parts A through F.
Answers
Given:
The car ride from Kiley's house to the airport.
Distance =24.3 miles.
Time =1/2 hour.
We know that
\(\text{Average rate =}\frac{\text{Distance}}{\text{time}}\)Substitute Distance =24.3 miles and time =1/2 hour to compute the average rate of the car ride from Kiley's house to the airport.
\(=\frac{24.3\text{ miles}}{\frac{1}{2}\text{hours}}\)\(\text{ Use }\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a}{b}\times\frac{d}{c}\text{.}\)\(=24.3\times\frac{2}{1}\text{ miles per hour}\)\(=24.3\times2\text{ miles per hour}\)\(=48.6\text{ miles per hour}\)Hence the average rate of the car ride from Kiley's house to the airport is 48.6 miles per hour.
2)
Given that they walked 3/4 hours to the waiting area and covered the distance of 1.2 miles.
Distance =1.2 miles.
Time =3/4 hours.
we know that
\(\text{Average rate =}\frac{\text{Distance}}{\text{time}}\)Substitute distance =1.2 miles and time =3/4 hours to compute the average rate of the walk from the car to the waiting area by the gate, at the airport.
\(=\frac{1.2\text{ miles}}{\frac{3}{4}\text{ hours}}\)\(=1.2\times\frac{4}{3}\text{ miles per hour.}\)\(=\frac{1.2\times4}{3}\text{ miles per hour.}\)Multiplying 1.2 and 4, we get 4.8
\(=\frac{4.8}{3}\text{ miles per hour.}\)Dividing 4.8 by 3, we get 1.6
\(=1.6\text{ miles per hour.}\)Hence at the airport, the average rate of the walk from the car to the waiting area by the gate is 1.6 miles per hour.

Step-by-step explanation:
Scott is making a dip that has 3 /5 of a teaspoon of garlic for every 1 /2 of a teaspoon of hot sauce.
3/5 teaspoon of garlic = 1/2 teaspoon of hot sauce
1/2 teaspoon of hot sauce = 3/5 teaspoon of garlic
1 teaspoon of hot sauce =
= 1 × 3/5 ÷ 1/2
= 3/5 ÷ 1/2

Answers
The equation in Standard Form. b) Identify P(x). c) Identify Q(x). d) Evaluate Integrating Factor. e) Solve for the general solution are given below:
a) Rewrite the equation in Standard Form:
To rewrite the equation in standard form, divide the entire equation by x⁴:
dy/dx + 2y = e^(-x)
b) Identify P(x):
In standard form, the coefficient of the y term is 2, which is the function P(x). So, P(x) = 2.
c) Identify Q(x):
In standard form, the right-hand side of the equation is e^(-x), which is the function Q(x). So, Q(x) = e^(-x).
d) Evaluate the Integrating Factor:
The integrating factor (IF) is given by the exponential of the integral of P(x) with respect to x. In this case, the integrating factor is:
IF = e^(∫P(x)dx) = e^(∫2dx) = e^(2x)
e) Solve for the general solution:
Multiply the entire equation by the integrating factor (IF = e^(2x)):
e^(2x) * (dy/dx + 2y) = e^(2x) * e^(-x)
Simplify the left side by applying the product rule of exponents:
(e^(2x) * dy/dx) + 2y * e^(2x) = e^(x)
Notice that the left side is now in the form (f(x)g(x))' = f'(x)g(x) + f(x)g'(x), where f(x) = y and g(x) = e^(2x). Apply the product rule and simplify further:
(d/dx)(y * e^(2x)) = e^(x)
Integrate both sides with respect to x:
∫(d/dx)(y * e^(2x)) dx = ∫e^(x) dx
Integrating the left side gives:
y * e^(2x) = ∫e^(x) dx = e^(x) + C₁, where C₁ is the constant of integration.
Finally, solve for y by dividing both sides by e^(2x):
y = (e^(x) + C₁) / e^(2x)
This is the general solution to the given differential equation using the Integrating Factor Method.

Here is part of a timetable for the Paris to Montpellier express train service.
The average speed of the 20 07 train from Paris is 224 km/h. Work out the distance this train travels from Paris to Montpelli
Answers
Answer:
772.8 km
Step-by-step explanation:
Speed is the rate of change of distance. Speed is the ratio of distance travelled to time taken. Average speed is the ratio of the total distance travelled to the total time taken, it is given by:
Average speed = Total distance / total time
The 20 07 train leaves Paris at 20:07 and reaches Montpellier at 23:34. This means that the total time taken is 3 hours 27 minutes, that is 3.45 hours.
Given that average speed is 224 km/h, hence:
Average speed = total distance / total time
224 km/h = total distance / 3.45 h
total distance = 224 * 3.45 = 772.8 km
Consider the set of all 3x3 lower triangular matrices with real entries.
a. Show that S is a subspace of V, the vector space of all 3x3 matrices with real entries.
b. Find a basis and dimension for S
Answers
a. As S satisfied the closure under addition, closure under scalar multiplication and non-empty condition S is a subspace of V.
b. The dimension of S is 6.
a. To show that S is a subspace of V, we need to verify that it satisfies the three subspace axioms:
i. Closure under addition:
Let A and B be two matrices in S.
We need to show that A + B is also a lower triangular matrix.
Since A and B are lower triangular, we know that their sum will also be a lower triangular matrix because the sum of two lower triangular matrices is still lower triangular. Therefore, A + B is in S and S is closed under addition.
ii. Closure under scalar multiplication:
Let A be a matrix in S and c be a scalar.
We need to show that c A is also a lower triangular matrix.
Since A is lower triangular, c A will also be lower triangular because multiplying each element in a lower triangular matrix by a scalar will not change its lower triangular form.
Therefore, c A is in S and S is closed under scalar multiplication.
iii. non-empty:
The zero matrix is a lower triangular matrix, so it is in S.
Therefore, S is a subspace of V.
b. To find a basis for S, we need to find a set of linearly independent vectors that span S.
Let's consider the matrix entries in a lower triangular matrix A:
a11 0 0
a21 a22 0
a31 a32 a33
We can see that the entries above the diagonal (a21, a31, and a32) can take any real value, while the entries on the diagonal (a11, a22, and a33) can also take any real value but the entries below the diagonal (all zeros) are fixed.
Therefore, we can construct a basis for S using these fixed entries:
B = {
[ 1 0 0 ]
[ 0 1 0 ]
[ 0 0 1 ]
[ 0 0 0 ]
[ 0 0 0 ]
[ 0 0 0 ]
}
The dimension of S is equal to the number of elements in its basis, which is 6.

Answers
La suma de las cifras del precio del rollo de alambre es aproximadamente 27.
Para resolver este problema, vamos a llamar "x" al precio del rollo de alambre en soles (S/).
Según la información proporcionada, podemos establecer la siguiente ecuación:
\((\frac{x}{2} )+(\frac{2x}{3} )+(\frac{5x}{8} )= 3870\)
Para simplificar la ecuación, vamos a deshacernos de los denominadores multiplicando toda la ecuación por el mínimo común múltiplo (MCM) de 2, 3 y 8, que es 24.
La ecuación simplificada será:
\(12x + 16x + 15x = 24 \times 3870\)
\(43x = 92880\)
\(x = \frac{92880}{43}\)
\(x \approx 2158.605\)
El precio del rollo de alambre es aproximadamente S/2158.605.
Para obtener la suma de las cifras, redondearemos el precio a dos decimales y luego sumaremos cada dígito:

Applying the distributive property and precedence of operations, the results to each side of the expression is of 2/5, hence they property holds.
Left-hand side:The left-hand side of the expression is defined as follows:
2/5(4/3-1/3)
Applying the distributive property, 2/5 multiplies each term as follows:
2/5(4/3-1/3) = 8/15 - 2/15
(multiplication of fractions -> multiply numerators and denominators with themselves).
They have common denominator, then the subtraction of the fractions is calculated as follows:
2/5(4/3-1/3) = 8/15 - 2/15 = 6/15
6 and 15 are divisible by 3, hence the fraction is simplified as follows:
6/15 = 2/5.
Right-hand sideThe right-hand side of the expression is given as follows:
2/5 x 4/3 - 2/5 x 1/3
We have two operations, subtraction and multiplication. The multiplication has higher precedence, hence:
2/5 x 4/3 - 2/5 x 1/3 = 8/15 - 2/15
