A person invests 5500 dollars in a bank. The bank pays 6.75% interest compound monthly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 13200 dollars?
We have been given that a person invests 5500 dollars in a bank. The bank pays 6.75% interest compound monthly. We are asked to find the time that will take the amount to 13,200 dollars.
We will use compound interest formula to solve our given problem.
[tex]A=P(1+\frac{r}{n})^{nt}[/tex], where,
A = Final amount,
P = Principal amount,
r = Annual interest rate in decimal form,
n = Number of times interest is compounded per year,
t = Time in years.
[tex]6.75\%=\frac{6.75}{100}=0.0675[/tex]
Upon substituting our given values in above formula, we will get:
[tex]13200=5500(1+\frac{0.0675}{12})^{12\cdot t}[/tex]
[tex]13200=5500(1+0.005625)^{12\cdot t}[/tex]
[tex]13200=5500(1.005625)^{12\cdot t}[/tex]
[tex]\frac{13200}{5500}=(1.005625)^{12\cdot t}[/tex]
[tex]2.4=(1.005625)^{12\cdot t}[/tex]
Now we will take natural log on both sides.
[tex]\text{ln}(2.4)=\text{ln}((1.005625)^{12\cdot t})[/tex]
Using natural log property [tex]\text{ln}(a^b)=b\cdot \text{ln}(a)[/tex], we will get:
[tex]\text{ln}(2.4)=12t\cdot \text{ln}(1.005625)[/tex]
[tex]t=\frac{\text{ln}(2.4)}{12\cdot \text{ln}(1.005625)}[/tex]
[tex]t=13.00635[/tex]
Upon rounding to nearest tenth, we will get:
[tex]t\approx 13.0[/tex]
Therefore, it will take approximately 13.0 years for the amount to reach $13200.

Two negative integers are 5 units apart on the number line, and their product is 126. What is the sum of the two integers?
–23
–5

14
Answer:
-23
Step-by-step explanation:
-23 is the answer
The sum of the two integers if they are 5 units apart on the number line, and their product is 126 is -23
System of equationsSystem of equations are equations that contain unknown variables with more than 1 equation.
Let the required integers be x and y.
If two negative integers are 5 units apart on the number line, then;
x - y = 5
x = 5 + y
If their product is 126, hence:
x y = 126
Substitute
5+y(y) = 126
5y + y^2 = 126
y^2 + 5y - 126 = 0
Factorize
y^2 + 14y - 9y - 126 = 0
y(y + 14) - 9(y + 14) = 0
y = 9 and - 14
Since the integers are negative, hence;
x = 5 + y
x = 5 - 14
x = -9
Sum = -14 + (-9)
sum = -23
Hence the sum of the two integers is -23

Given:
The figure contains a right triangle.
The two angles of the triangle are 45° each.
The length of one leg is 3 units.
The length of the hypotenuse is x units.
We need to determine the value of x.

Let R be the region in the first quadrant of the xy-plane bounded by the hyperbolas xyequals1, xyequals9, and the lines yequalsx, yequals4x. Use the transformation x equals StartFraction u Over v EndFraction , y equals uv with ugreater than0 and vgreater than0 to rewrite the integral below over an appropriate region G in the uv-plane. Then evaluate the uv-integral over G.
To rewrite the integral over an appropriate region G in the uv-plane, we need to use the given transformation x = u/v and y = uv. The region G is defined by certain constraints on u and v, which can be found by solving the inequalities derived from the boundaries of R in the xy-plane. Finally, we can set up and evaluate the double integral over G.
Explanation:To rewrite the integral over an appropriate region G in the uv-plane, we need to use the given transformation x = u/v and y = uv. Let's consider each boundary of R separately:
For the hyperbola xy = 1, substituting the given transformations, we get (u/v)(uv) = 1, which simplifies to u^2 = v.For the hyperbola xy = 9, substituting the given transformations, we get (u/v)(uv) = 9, which simplifies to u^2 = 9v.For the line y = x, substituting the given transformations, we get uv = u/v.For the line y = 4x, substituting the given transformations, we get uv = 4(u/v).Now, we need to find the region G in the uv-plane that corresponds to R in the xy-plane. The region G is defined by the following constraints: u^2 ≤ v, 9v ≥ u^2, uv ≤ u/v, and uv ≥ 4(u/v). Combining these constraints, we get u^4 ≤ v^2 ≤ 9u^3 and u^2 ≤ 4v. The boundaries of G can be found by solving these inequalities.
To evaluate the integral over G, we need to determine the limits of integration for u and v. Once we have the limits, we can set up the double integral of the function over G and evaluate it.

The solution to x - 8 > - 3
Answer: x > 5
Step-by-step explanation: To solve for x in this inequality, your goal is the same as it would be if you were solving an equation, to get x by itself on one side.
Since 8 is being subtracted from x, add
8 to both sides of the inequality.
On the left the -8 +8 cancels out
and on the right, -3 + 8 is 5.
So we have x > 5.
Consider the effect of the transformation (x, y) → (x, 2y) on the parallelogram ABCD with vertices A(0, 0), B(1, 1), C(3, 1), and D(2, 0). Select True or False for each statement.
The transformation (x, y) → (x, 2y) doubles the y-coordinates of the parallelogram ABCD vertices, resulting in a new parallelogram with doubled height and consequently doubled area, demonstrating that the change in height is proportional to the original height.
Explanation:The question posed relates to the effect of a transformation on the coordinates of a parallelogram's vertices. Specifically, we look at the transformation (x, y) → (x, 2y), which stretches the y-coordinates of the vertices while keeping the x-coordinates unchanged. For the given parallelogram ABCD with vertices A(0, 0), B(1, 1), C(3, 1), and D(2, 0), we apply the transformation to each vertex:
Vertex A(0, 0) becomes A'(0, 0 × 2) = A'(0, 0)Vertex B(1, 1) becomes B'(1, 1 × 2) = B'(1, 2)Vertex C(3, 1) becomes C'(3, 1 × 2) = C'(3, 2)Vertex D(2, 0) becomes D'(2, 0 × 2) = D'(2, 0)The transformation doubles the height (y-coordinate) of the parallelogram, while the base (x-coordinate) remains the same. Consequently, the area of the parallelogram also doubles, confirming that the change in height is proportional to the original height. By applying the transformation to a simple geometric figure, students can visualize and understand the properties of transformations and their effects on the shapes.

What does 9(3-2x)=2(10-8x) equal to
Answer:
x=72 x = 7 2
Step-by-step explanation:
Answer:
x=7/2
Step-by-step explanation:
First, distribute the 9 on the left side
9(3-2x)=2(10-8x)
(9*3)+(9*-2x)= 2(10-8x)
27-18x= 2(10-8x)
Next, distribute the 2 on the right side
27-18x=(2*10)+(2*-8x)
27-18x=20-16x
Now, move all the numbers to one side of the equation, and the variables to the other.
27-18x=20-16x
Add 18x to both sides
27-18x+18x=20-16x+18x
27=20+2x
Subtract 20 from both sides
27-20=20-20+2x
7=2x
Now all the variables are on one side, and the numbers are on the other. x is still not by itself. It is being multiplied by 2. To undo this, divide both sides by 2
7/2=2x/2
7/2=x

Final answer:
The expression [tex]4^4(4^-7)(4[/tex]) simplifies to [tex]4^-2[/tex] by adding the exponents of the same base, resulting in a single exponent expression.
Explanation:
To simplify the expression [tex]4^4(4^-7)(4)[/tex] using a single exponent, you'll need to apply the rules of exponents. When you have the same base being multiplied, you can add the exponents. Start by looking at the terms 4^4 and 4^-7. The rule says to add the exponents when multiplying: 4 + (-7) = -3. So those two terms combine to make 4^-3.
Next, we have the single 4, which can also be written as 4^1 since any number to the power of 1 is itself. Now add the exponents again: -3 + 1. This gives us[tex]4^-2[/tex], which is the expression simplified with a single exponent.
