An amount of $35,000 is borrowed for 11 years at 7.5% interest, compounded annually. If the loan is paid in full at the end of that period, how much must be paid back?
The amount paid back when the loan is paid in full at the end of that period will be $77,546.3.
Given that:
Principal, P = $35,000
Rate, r = 7.5% or 0.075
Time, n = 11 years
The amount (A) is calculated as,
A = P(1 + r)ⁿ
If the loan is paid in full at the end of that period, then the amount paid back is calculated as,
A = $35,000 x (1 + 0.075)¹¹
A = $35,000 x (1.075)¹¹
A = $35,000 x 2.2156
A = $77,546.3

A watermelon was ejected from a catapult reaching a maximum height of 20 ft. The watermelon left the catapult when it was 4 ft off the ground and hit the ground 45 ft away from the catapult. Can the equation that models the path of the watermelon be written given the information in the problem? If so, find the equation. If not, state what other information is needed.
Answer:
Step-by-step explanation:
No, the equation cannot be written with the given information. The distance from the catapult when the watermelon reached the maximum height is needed. Since the watermelon did not start on the ground, it cannot be assumed that the maximum was reached half the distance to the landing point.

, where α,β>0, satisfies the following properties: (a) local nonsatiation, (b) decreasing marginal utility for both goods 1 and 2, (c) quasi-concavity, and (d) homotheticity.
The Cobb-Douglas utility function satisfies the properties of local non-satiation, decreasing marginal utility for both goods, quasi-concavity, and homotheticity.
The Cobb-Douglas utility function u(x1, x2) = xi^(α) * x2^(β), where α and β are both greater than zero, satisfies the following properties:
(a) Local non-satiation:
This property states that at each point of the consumption set, there is always another bundle that is arbitrarily close and strictly preferred. Thus, the function has local non-satiation.
(b) Decreasing marginal utility for both goods 1 and 2: The marginal utility of a good measures the utility obtained by consuming one more unit of it. The marginal utility of x1 can be obtained as:
MU1 = α * xi^(α−1) * x2^(β)
The marginal utility of x2 can be obtained as:
MU2 = β * xi^(α) * x2^(β−1)
Therefore, both marginal utilities are decreasing in x1 and x2, satisfying this property.
(c) Quasi-concavity:
The Cobb-Douglas function is quasi-concave. This means that the upper contour set of any level set of the function is convex. This can be proved by taking the second partial derivative of the function and checking whether it is negative or not.
(d) Homotheticity:
The Cobb-Douglas function is homothetic. This means that its shape is independent of the total level of utility. The proof can be achieved by checking whether the function is homogeneous of degree one or not. This is true, since multiplying the inputs by any positive scalar λ leads to a proportional increase in the output.
In conclusion, the Cobb-Douglas utility function satisfies all four properties - local non-satiation, decreasing marginal utility for both goods 1 and 2, quasi-concavity, and homotheticity.

what is the distance, to the nearest whole number, from K(5,6) to P(1,-4)
Answer:
The distance between the two points is approximately 11 units
Step-by-step explanation:
Here, we are to give the distance between the given two points to the nearest whole number;
To calculate the distance, we shall be using the distance formula;
D = √(x2-x1)^2 + (y2-y1)^2
(x1,y1) = (5,6)
(x2,y2) = (1,-4)
D = √(1-5)^2 + (-4-6)^2
D = √((-4)^2 + (-10)^2
D = √(16+100)
D = √(116)
D = 10.77 units which is approximately 11 units

Find the 7th term.
Answer:
a7 = 1/243
Step-by-step explanation:
The formula for the nth term of a geometric series is
\(a_{n}=a_{1}r^n^-^1\), where a1 is the first term, r is the common ratio, and n is the position of the term (e.g., 6th or 3rd).
First, we need to find the common ratio.
We can find it by dividing the second term (1) by the first term (3):
\(r=\frac{a_{2} }{a_{1} }=\frac{1}{3}\)
Since we already know a1 and r, we simply substitute 7 for n to find the 7th term:
\(a_{7}=3*\frac{1}{3} ^7^-^1\\a_{7}=3*\frac{1}{3}^6\\ a_{7}=3*\frac{1}{729}\\ a_{7}=\frac{1}{243}\)
What is the first step in evaluating the expression (5 + 8 ÷ 4 × 3)^2 − 7?
72° (x+4)° Write an equation that can be used to find the value of x.
Answer:
In a triangle, the sum of the interior angles is 180 degrees. So, we can set up the following equation:
72° + (x+4)° + A = 180°
where A is the measure of the third angle in the triangle.
Simplifying the equation, we get:
(x+4)° + 72° + A = 180°
x + 76° + A = 180°
Subtracting 76° from both sides, we get:
x + A = 104°
Therefore, an equation that can be used to find the value of x is x + A = 104°, where A is the measure of the third angle in the triangle. Note that we do not have enough information to solve for x or A individually, but we can use this equation to relate the two angles in the triangle.
if 6 bottles are randomly selected, what is the probability that this results in two bottles of each variety being chosen?
There are 69300 possible ways of selecting six bottles randomly with two bottles of each variety.
Probability is a branch of mathematics concerned with numerical descriptions of how likely an event is to occur or how likely a statement is to be true. In the given question, we have to select 6 bottles randomly with two bottles of each variety,
= ¹⁰C₂× ⁸C₂ × ¹¹C₂
¹⁰C₂= [1 × 2 × 3 × 4 × 5 × 6 × 7 × 8 × 9 × 10] / [(1 × 2)(1 × 2 × 3 × 4 × 5 × 6 × 7 × 8)]
= 90/2
= 45
Similarly, ⁸C₂ = 28
In the same way ¹¹C₂= 55
= ¹⁰C₂× ⁸C₂× ¹¹C₂
= 45 × 28 × 55
= 69300
Therefore, there are 69300 possible ways of selecting 6 bottles with two bottles of each variety.

Draw a number line and place these fractions on it:
2/3 1/10 7/8
A number line is a graphical representation of numbers in a linear format. It is a useful tool to help visualize the relative positions of numbers, especially fractions.
To place the fractions 2/3, 1/10, and 7/8 on a number line, we need to first identify their relative positions in terms of magnitude.
Starting at 0 on the number line, we can place 1/10 to the right of 0, followed by 2/3 and then 7/8, in order from left to right. Since 2/3 is greater than 1/10 but less than 7/8, it is placed between these two fractions on the number line. The resulting number line would show the relative positions of these three fractions in relation to each other and to the whole numbers. This can help in comparing and ordering fractions, as well as in visualizing their relative magnitudes.

division was used in the first example.
a 12-ft-by-15-gt rectangular swimming pool has a 3-ft-wide no-slip surface around it. what is the outer preimeter of the no-slip surfaec
If a 12-ft-by-15-gt rectangular swimming pool has a 3-ft-wide no-slip surface around it. The outer perimeter of the no-slip surface around the rectangular swimming pool is 78 feet.
The key idea in this problem is to recognize that the no-slip surface around the pool consists of a rectangular strip of uniform width that runs parallel to the edges of the pool. To find the outer perimeter of this strip, we need to add up the lengths of all four sides of the rectangle formed by the outermost edges of the no-slip surface.
Let's start by finding the length of the no-slip surface that runs along the length of the pool. Since the pool is 12 feet long and the no-slip surface extends 3 feet beyond each end of the pool, the total length of the no-slip surface is:
12 + 2(3) = 18 feet
The "2(3)" term in this equation represents the 3-foot-wide extension on each end of the pool. Next, we need to find the length of the no-slip surface that runs along the width of the pool. Since the pool is 15 feet wide and the no-slip surface extends 3 feet beyond each side of the pool, the total width of the no-slip surface is:
15 + 2(3) = 21 feet
Now we have the lengths of the two parallel sides of the rectangle formed by the outermost edges of the no-slip surface. To find the lengths of the other two sides, we simply add up the lengths of the corresponding sides of the pool.
Therefore, the length of the rectangle is 12 + 2(3) = 18 feet, and the width of the rectangle is 15 + 2(3) = 21 feet.
Finally, we can add up the lengths of all four sides of the rectangle to find the outer perimeter of the no-slip surface:
2(18) + 2(21) = 36 + 42 = 78 feet.
