Dave opens a savings account that has an annual simple interest rate of 0.1%. If he initially deposits $1500, find the amount in the savings account after 5 years. PLEASE HELP WILL GIVE 20 POINTS
Answers
The amount in his savings after 5 years will be $1507.5.

It will take around 0.24 months for the invested money to get doubled.
What is compound interest?The compound interest is a form of interest where the rate of interest is applied on the amount obtained after every interval of time.
The formula to calculate the amount is as follows,
A = P[tex](1 + r)^{(nt)}[/tex]
Substitute all the corresponding values in the above expression to obtain,
A = P[tex](1 + 6/100)^{nt}[/tex]
1800 = 900[tex](1 + 6/100)^{nt}\\[/tex]
=> [tex](1 + 6/100)^{nt}[/tex] = 1800/900
=> [tex]1.06^{nt}[/tex] = 2
Since, there are 12 months in one year, n = 12.
[tex]1.06^{12t}[/tex] = 2
=> 12t = log(2) ÷ log(1.06)
=> 12t = 0.275

Answers
It is necessary to compute in the volume of the rotated region while taking into account that each cross section piece is raised up by a height of h = 4 - y. Scale the results by 62.4 lb/ft3 as well.
The given parabolic region's volume of revolution about the y-axis is a parabolic cylinder. This solid is revolved, and it has circular disks as its cross section. The differential volume of one such disk situated at a differential height y above the x-axis must be determined. The weight of water in this volume can then be calculated by multiplying this volume by the density of water. The depth of this volume is then determined from the tank's top surface. Determine how much differential work is needed to lift this water layer to the top surface. Integrate this differential work now to calculate the overall effort needed to empty the tank.
Rotating the curve x=3y about the y-axis creates the region. Keep in mind that 62.5 = (125 / 2) As a result, using the disk method,
[tex]\int_{0}^{3} \left(\frac{125}{2} \pi (4-y) (3\sqrt{y})^2\right)\, dy \\ &=\int_{0}^{3} \left(\frac{1125}{2} \pi (4-y) y\right)\, dy &\text[/tex]

The values of x in the first, second, third and fourth triangles are 4 units, 70°, 76° and 80° respectively
How to determine the values of x in the triangle?
To solve this problem, we need some angle geometry knowledge:
For the first triangle:
x = 4 (All sides in a rhombus are identical)
For the second triangle:
The missing side is also equal to x (base of isosceles triangles)
x + x + 40 = 180 (sum of angles in triangle)
2x+40 = 180
2x = 180-40
2x = 140
x = 70°
For the third triangle:
x = 76° (base of isosceles triangles are equal)
For the fourth triangle:
Check the image attached for labeling
m = 180-110 = 70° (angle on a straight line)
y = 70° (base of isosceles triangles are equal)
z = 180-70-70 = 40°
t = 90-40 = 50°

The number of acres owned for which the average intake is 2200 calories per day is 2 acres obtained by the algebraic expression that relates the acres of land and the calories per day.
What is an algebraic expression?An algebraic expression is formed by variables, constants, and arithmetic operations.An algebraic expression provides the relation between the input and output variables i.e., x and f(x) respectively.Calculation:It is given that, the number of calories consumed daily by a person owing x acres of land is given by the algebraic expression,
C(x) = 270 ln(x+1) + 1900
The average intake of calories consumed per day is given by C(x) = 2200
Here x is the number of acres of land. Then, the required number of acres of land is
C(x) = 270 ln(x+1) + 1900
⇒ 2200 = 270 ln(x+1) + 1900
⇒ 270 ln(x+1) = 2200 - 1900
⇒ 270 ln(x+1) = 300
⇒ ln(x+1) = 300/270 = 10/9
Applying base 'e' on both sides, we get
⇒ (x+1) = [tex]e^\frac{10}{9}[/tex]
⇒ x+1 = 3.0377
⇒ x = 3.0377 - 1 = 2.0377
When rounding the final answer to the nearest tenths, we get x = 2 acres.
When rounding the final answer to the nearest thousand, we get x = 2.038 acres.
Thus, for an average intake of 2200 calories per day, the number of acres of land owned is approximately 2 acres.

Answers
The simplification of the given expression is (x - 1)²/ (x-2)(x+3) which restrictions on the domain of this expression are x ≠ 1, 2, -3.
The expression is given in the question as:
(x+3)(x-1)/(x-2) ÷ (x+3)/(x-1)
To simplify the expression (x+3)(x-1)/(x-2) ÷ (x+3)/(x-1), we can start by multiplying the numerator and denominator of the first fraction by the denominator of the second fraction:
(x+3)(x-1)/(x-2) ÷ (x+3)/(x-1)
= (x+3)(x-1) / (x-2) × (x-1) / (x+3)
Then, we can simplify the expression by combining like terms:
= (x - 1)² (x+3)/ (x-2)(x+3)
= (x - 1)²/ (x-2)(x+3)
The restrictions on the domain of this expression are that x cannot be equal to 2 or -3, because these values would make the denominator equal to zero, which is not allowed in a fraction.
Therefore, the domain of the expression is all real numbers except x = 1, x = 2, and x = -3. We can express this as:
