Answer:
$157.92.
Step-by-step explanation:
a) To calculate how long it takes Penny to pay off the loan, we can use the formula:
n = log(P/A) / log(1 + r/12),
where n is the number of months, P is the initial loan amount ($4500), A is the monthly payment ($160), and r is the annual interest rate (3%).
n = log(4500/160) / log(1 + 0.03/12)
n = log(28.125) / log(1.0025)
n = 3.7062
Rounding up, it takes Penny 4 months to pay off the loan.
b) To calculate the amount of Penny's final payment, we can use the formula:
P = A * (1 - (1 + r/12)^-n),
where P is the remaining balance, A is the monthly payment ($160), n is the number of months (4), and r is the annual interest rate (3%).
P = 160 * (1 - (1 + 0.03/12)^-4)
P = 160 * (1 - (1.0025)^-4)
P = $157.92
Therefore, it takes Penny 4 months to pay off the loan and her final payment is $157.92.

Answer:
[tex]\boxed{\mbox \large a = \dfrac{9}{10} = 0.9}[/tex]
Step-by-step explanation:
Equation to be solved is
[tex]\dfrac{5}{3}a + \dfrac{4}{5} = a + \dfrac{7}{5}[/tex]
Step 1
Get rid of those annoying denominators by multiplying throughout 15. We choose 15 because it is the lowest common multiple of 3 and 5. Since 3 and are prime numbers the LCM is 3 x 5 = 15
[tex]15 \cdot \dfrac{5}{3}a +15 \cdot \dfrac{4}{5} = 15\cdot a + 15\cdot \dfrac{7}{5}}[/tex]
==> [tex]25a + 12 = 15a + 21}\\[/tex]
Step 2
Subtract 15 from both sides:
==> [tex]25a -15a + 12 = 15a -15a + 21}\\\\\\ 10a + 12 = 21}\\[/tex]
Step 3
Subtract 21 from both sides
[tex]10a + 12 -12 = 21 - 12\\\\[/tex]
[tex]10a = 9[/tex]
Step 4
Divide by 10 both sides
[tex]\dfrac{10a}{10} = \dfrac{9}{10}\\\\\implies a = \dfrac{9}{10} = 0.9[/tex]

represents a relation.
Answer:
Yes, the set of ordered pairs (1, 7), (3, 8), (3, 6), (6, 5), (2, 11), (1, 4) represents a relation. This relation is a function since each input (x-value) has a single output (y-value).
Step-by-step explanation:
the graph of the function f shown consists of three line segments. if the function g is an antiderivative of f such that g(2)=5, for how many values of c, where 0
The only value of c that satisfies the initial condition g(2) = 5 is c = -3.
The graph of a function f consists of three line segments, with points (1,2), (2,3), and (3,4).
An antiderivative of f is a function g such that g'(x) = f(x). That is, g is the "opposite" of the derivative of f. The values of c in an antiderivative g(x) = f(x) + c are determined by the initial condition g(2) = 5, since g'(2) = f(2) = 3.
So, in order to determine the value of c, we need to integrate f(x) and find the value of g(2). The integral of f(x) is
g(x) = x² + 2x + c
Substituting x = 2 into this equation, we get
g(2) = 4 + 4 + c = 8 + c
Now, since g(2) = 5, we can solve for c:
5 = 8 + c
c = -3
Therefore, the only value of c that satisfies the initial condition g(2) = 5 is c = -3.

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Considering the two lines are parallel, they both have the same slope.
let m be the slope of the two lines:
y=mx+y₀
y=mx+y₁
y₀, y ₁ are the value on y axis where the two lines cross the axis.
Because the lines are parallel, there exists no point that lies on both lines, therefore the system has 0 solution.
Hence, y=x+1 and y=x-5 are the equations of the lines in the given graph.

A. $137,547. 52
B. $149,546. 52
C. $73,734. 84
D. $195,589. 79
(a) The future value is $18,971.06, which is closest to option D) $64,521.06
(b) So the present value of the estimated payments is $317,375, which is closest to option A) $350,623.10
(c) The present value of the savings is $25,620.51, which is closest to option C) $73,734.84
A) The future value of the deposits can be calculated using the formula for compound interest:
FV = PV * (1 + r/n)^(nt)
where
PV = $7,000
r = 12% = 0.12
n = 2 (compounded semiannually)
t = 5 years = 10 semiannual periods
Plugging in these values, we get:
FV = $7,000 * (1 + 0.12/2)^(2 * 10)
FV = $7,000 * (1.06)^20
FV = $7,000 * 2.667532622
FV = $18,971.06
B) The present value of the estimated payments can be calculated using the formula for the present value of an annuity:
PV = PMT * (1 - (1 + r)^(-n)) / r
where
PMT = $31,000
r = 8% = 0.08
n = 20 payments (from age 70 to 90)
Plugging in these values, we get:
PV = $31,000 * (1 - (1 + 0.08)^(-20)) / 0.08
PV = $31,000 * (1 - 0.170811153) / 0.08
PV = $31,000 * 0.83 / 0.08
PV = $31,000 * 10.375
PV = $317,375
C) The present value of the savings can be calculated using the formula for present value of a lump sum:
PV = FV / (1 + r/n)^(nt)
where
FV = $12,000 * 10 (total savings)
r = 10% = 0.1
n = 2 (compounded semiannually)
t = 10 years = 20 semiannual periods
Plugging in these values, we get:
PV = ($12,000 * 10) / (1 + 0.1/2)^(2 * 20)
PV = ($120,000) / (1.05)^40
PV = $120,000 / 4.68
PV = $25,620.51

For given functions, f(g(4)) = 2, f(f(8)) = ∛2 and f(g(x)) = ∛ ( x² - 8 ).
Describe a function.A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range and a co-domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).
In math, various function types exist. Among the crucial kinds are:
When there is a mapping for a range for each domain between two sets, this is known as an injective function or one to one function.
When more than one element is mapped from domain to range, the function is said to be surjective or to be an onto function.
a polynomial function is a function made by of polynomials
Now,
For functions f(x) = ∛ x and g(x) = x²-8
f(g(x)) = ∛ (x²-8)
f(f(x)) = ∛ ∛ x
g(f(x)) = ( ∛ x ) ² - 8

The set s = {(-5, 7)} is not a basis for R^2 (the two-dimensional real vector space) for several reasons:
Cardinality: A basis for a vector space must contain at least two linearly independent vectors. Since s contains only one vector, it cannot be a basis for R^2, which has dimension 2.
Linear independence: A basis must contain linearly independent vectors. If a vector in the basis can be written as a linear combination of the other basis vectors, it is not linearly independent, and the set cannot be a basis.
Spanning: A basis must span the entire vector space, meaning that every vector in the vector space can be written as a linear combination of the basis vectors. The set s = {(-5, 7)} does not span R^2 because it contains only one vector, and not every vector in R^2 can be written as a scalar multiple of this vector.
Therefore, s = {(-5, 7)} cannot be a basis for R^2 because it does not satisfy the three requirements of a basis: having at least two linearly independent vectors, containing only linearly independent vectors, and spanning the entire vector space.

In a class of 10 , there are 5 students who play soccer. If the teacher chooses 2 students, what is the probability that both of them play soccer?
The probability of choosing 2 students who both play soccer from a class of 10 students, where 5 students play soccer, is 5/6 or 0.83.
The probability of choosing 2 students who both play soccer from a class of 10 students, where 5 students play soccer, can be calculated using the formula for combinations:
[tex]C(5,2) =\frac{5!}{(2! * (5-2)!)}[/tex]
[tex]= \frac{10}{(2 * 3!)} \\ \\=\frac{10}{(2 * 6) } \\\\= \frac{5}{6}[/tex]
So, the probability of choosing 2 students who both play soccer is 5/6 or 0.83.
This means that if the teacher randomly selects 2 students from the class, there is an 83% chance that both of them play soccer.
In conclusion, the probability of choosing 2 students who both play soccer from a class of 10 students, where 5 students play soccer, is 5/6 or 0.83.

1. Let X = {a} and Y = {a,b}, do the following. (8 points, 4 each) (a). Use the set-roster notation to write set (XXX) XY. (b). Find two functions and two non-function relations from X x Y to Y.
Two non-functions could be (a,a) -> a and (a,b) -> a and (a,a) -> b and (a,b) -> b, meaning that both inputs can result in either a or b.
A set is a collection of distinct objects, which can be anything, such as numbers, letters, or even other sets.
The set-roster notation is a way to write a set by listing its elements inside curly brackets {}.
(a) To write the set (XXX) XY, we need to repeat the set X three times, which would be X = {a,a,a}.
Then we can join it with the set Y to form (XXX) XY = {a,a,a,a,b}.
(b) To find two functions and two non-function relations from X x Y to Y, we need to understand what a function and a relation are. A function is for every element in the domain (X x Y), there is exactly one corresponding element in the codomain (Y) where as a non-function, or a relation, is a set of ordered pairs where the same input can have different outputs.

At a local high school, the 40% of the students drink soda regularly, 30% drink coffee regularly, and 10% drink both regularly. If a student was randomly selected from this school, what is the probability that the student drinks soda if we know the student drinks coffee regularly?.
The probability that the student drinks soda, given that they drink coffee, is 0.25.
Let's designate the proportion of students who regularly consume soda as "S," those who frequently consume coffee as "C," and those who regularly consume both as "B."
Since 40% of students frequently consume soda, there are 0.4S kids who do the same.
Additionally, there are 0.3S students who consume coffee because 30% of students do it frequently.
Additionally, since 10% of students consume both beverages, there are 0.1S students who also consume soda and coffee.
Students in the class S = 0.4S + 0.1S = 0.5S either drink soda or both.
The pupils in C = 0.3S + 0.1S = 0.4S either consume coffee or both.
So, given that the student drinks coffee, the probability of drinking soda is:
P(soda | coffee) = P(soda and coffee) / P(coffee)
= 0.1S / 0.4S
= 0.25.
