you want to buy a $32,000 car. The company is offering a 6% interest rate for 60 months. What will the monthly payments be?
Answers
The monthly payment will be $618.71
We know that the formula for the loans are:
[tex]P_0=\frac{d(1-(1+\frac{r}{k} )^{-Nk})}{\frac{r}{k}}[/tex]
where
P₀ is principal
d is monthly payment, annual payment

Answer:
Step-by-step explanation:
Use Heron's formula to find the area of the triangle with side lengths 6, 9, and 12, as shown below.
Answers
Answer:
√(6 + 9 +12) = √27 = 3√3
√(-6 + 9 + 12) = √15 = √3√5
√(6 - 9 + 12) = √9 = 3
√(6 + 9 - 12) = √3
(1/4)(3√3)(√3√5)(3)(√3)
= (1/4)(27√3)(√5) = (27√15)/4 = 26.1
Answer:correct answer is 26.1
Step-by-step explanation:
Heron's formula states that the area (A) of a triangle with side lengths a, b, and c is given by:
A = √(s(s-a)(s-b)(s-c))
where s is the semiperimeter, which is half the perimeter of the triangle:
s = (a + b + c) / 2
In this case, the side lengths are a = 6, b = 9, and c = 12. Therefore, the semiperimeter is:
s = (6 + 9 + 12) / 2 = 27 / 2
Using Heron's formula, we can now calculate the area of the triangle:

The risk-free rate is 8%, and the expected return on the market is 16%. As an analyst, you are preparing a recommendation report on the following stock:
Stock S
Beta 0.85
Expected dividend next year $1.10
Growth rate (g) 8%
Current Price (p0) $22
Using the SML, would you recommend to buy or sell the stock?
A) Sell, because the required rate is greater than the expected rate.
B) Sell, because the expected rate is greater than the required rate.
C) Buy, because the required rate is greater than the expected rate.
D) Buy, because the expected rate is greater than the required rate.
Answers
Correct Option is,
D) Buy, because the expected rate is greater than the required rate.
Now, Based on the information you've provided,
To calculate the required rate of return, we can use the SML formula as;
Required rate of return = risk-free rate + beta x (expected market return - risk-free rate)
Plugging in the numbers, we get:
Required rate of return = 8% + 0.85 x (16% - 8%)
= 14.6%
Since the expected rate of return for Stock S is,
= dividend yield + growth rate
= (1.1 / 22 + 8%),
= 9.4%
which is higher than the required rate of return of 14.6%,
Here, the stock is undervalued and would be a good buy.
Therefore, the answer is, option D) Buy, because the expected rate is greater than the required rate.

The answers are (-8, 5) and (-8, -5)
Given that, the point (8, 5) is on the graph of an even function, we need to find the other point must also be on the graph,
A function f(x) is said to be an even function if it satisfies the following equation: f(−x) = f(x)
A function satisfying this equation has a graph that is symmetric about the y-axis.
So, if the point (8, 5) is on the graph of an even function, the (-8, 5) must also be on the graph of the function.
Also, the point (8, 5) is on the graph of an odd function,
The graph of an odd function is symmetrical about the origin. Therefore, an odd function satisfies the following condition:
-f(x) = f(-x),

Therefore, (∀y)(∃z)(∃x)q(x, y, z).
Answers
Yes, The argument is valid.
Now, We have;
(∀x) (∃y) (p(x, y) ⇒ r(x))
Means that for any integer x, there exists an integer y such that if x is a factor of y, then x is prime.
(∀x)(∀y)(∀z)(¬q(x, y, z)) means that for any integers x, y, and z, the greatest common factor of x and y is not z.
(∃x)(∀y)(p(x, y) ∨ r(x)) means that there exists an integer x such that for any integer y, either x is a factor of y or x is prime.
Therefore, (∀y)(∃z)(∃x)q(x, y, z) means that for any integer y, there exists integers z and x such that the greatest common factor of x and y is z.
To see why this conclusion follows, consider that if (∀y)(∃z)(∃x)q(x, y, z) were false, then there would be some integer y such that for all integers z and x, the greatest common factor of x and y is not z.
However, this would contradict (∀x)(∀y)(∀z)(¬q(x, y, z)), which states that for any integers x, y, and z, the greatest common factor of x and y is not z.

The simplified expression for the difference in the areas of Circle A and Circle B is = 12π/(x+2)²
Area of a Circle:The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is [tex]A = \pi r^2[/tex], where r is the radius of the circle. The unit of area is the square unit, for example, [tex]m^2, cm^2, in^2[/tex], etc.
We know that :
The formula of circle's circumference is = 2πr
We have :
Circle A has a circumference of [tex]\frac{8\pi }{x+2}[/tex] units
and Circle B has a circumference [tex]\frac{4\pi }{x+2}[/tex]
Now, First we calculate the area of circle A is:
8π/x+2 = 2πr
r = 8π/x+2 × 1/2π
r = 4/x+2
Area = πr² = (4/x+2)²π
Now, for circle B
4π/x+2 = 2πr
r = 4π/x+2 × 1/2π
r = 2/2x+2
Area =( 2/2x+2)²π
Simplified expression for the difference in the areas of Circle A and Circle B are:
(4/x+2)²π - ( 2/x+2)²π
= π/(x+2)²( 4²-2²)
= π/(x+2)²(16-4)

The probability that Mia and Lia place in 1st or 2nd is 99/2450. There are two possible scenarios in which Mia and Lia can place in 1st or 2nd: Mia places 1st and Lia places 2nd, or Mia places 2nd and Lia places 1st. The probability of the first scenario is (1/50) * (1/49) = 1/2450. The probability of the second scenario is also (1/50) * (1/49) = 1/2450. Since these two scenarios are mutually exclusive, we can add their probabilities to find the total probability: 1/2450 + 1/2450 = 2/2450. However, we must also account for the fact that there are 49 other people who could place in 3rd. So the final probability is (2/2450) * 49 = 98/2450. Adding the probability that neither Mia nor Lia place in 3rd (1/2450), we get 98/2450 + 1/2450 = 99/2450.

The total surface area of a
rectangular prism is 1,060 cm². The
prism's base has measurements 8
centimeters and 10 centimeters.
What is the height of the prism?
Answers
Answer:
The surface area of a rectangular prism is given by the formula:
SA = 2lw + 2lh + 2wh
where l, w, and h are the length, width, and height of the prism, respectively. We are given that the surface area of the prism is 1,060 cm², and that the base has measurements 8 cm and 10 cm.
Substituting these values into the formula, we get:
1060 = 2(8)(10) + 2(8)h + 2(10)h
Simplifying and solving for h, we get:
1060 = 160 + 16h + 20h
1060 = 160 + 36h
900 = 36h
h = 25
Therefore, the height of the prism is 25 cm.
