Using the interest rates formula, we know that an automobile that costs $24588.44 is within our means.
What are interest rates?The amount of interest due each period expressed as a percentage of the amount lent, deposited, or borrowed is known as an interest rate.
The total interest on a loaned or borrowed sum is determined by the principal amount, the interest rate, the frequency of compounding, and the period of time the loan, deposit, or borrowing took place.
So, let's say the car's affordable price is P:
The entire payback is equal to P r/100 T + P.
In this case, P, r = 4.75, and T = 9 years.
$351,00 = P × (4.75/100 × 9 + 1)
$351,00 = P × ( 0.4275 + 1)
$351,00 = P × 1.4275
P = 351,00 / 1.4275
When you use the division operation, we receive:
P = $24588.44
Therefore, using the interest rates formula, we know that an automobile that costs $24588.44 is within our means.

PLEASE ANSWER CLEARLY WITH EQUATION
Samuel went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 300 mg of sodium and each frozen dinner has 450 mg of sodium. Samuel purchased 5 more frozen dinners than cans of soup and they all collectively contain 6000 mg of sodium. Write a system of equations that could be used to determine the number of cans of soup purchased and the number of frozen dinners purchased. Define the variables that you use to write the system.
ax + by = 6000 and a + 5 = b are two equations that might be used to calculate how many soup cans and frozen dinners were purchased.
What is an equation?
There are several methods to define a formula. A mathematical statement that establishes the equivalence of two mathematical expressions is the definition of an equation in algebra.
This is best shown by the formula 3x + 5 = 14. In this instance, the word equal comes between the phrases 3x + 5 and 14. Even the most basic algebraic equations include the usage of mathematical variables.
Let frozen supper be y and soup cans be x.
X now has 300 mg of sodium in it.
x = 300
Y also has 450 mg of sodium in it.
y = 450
Samuel reportedly buys five more frozen dinners than soup cans, and they all have a combined salt content of 6000 mg.
Let the number of frozen dinners be "b," and the number of soup cans be "a."
ax + by = 6000
⇒ a(300) + b(450) = 6000 ...1
Samuel bought 5 more frozen dinners than soup cans, according to the inquiry, which results in equation
a + 5 = b ...2
Now, by changing the value of b in equation 1 we obtain,
⇒ a(300) + (a + 5)(450) = 6000
⇒ 300a + 450a = 6000 - 2250
⇒ 750a = 3750
⇒ a = 3750/750
⇒ a = 5
By changing the value of an in equation 2, we obtain
⇒ 5 + 5 = b
⇒ b = 10
So, ax + by = 6000 and a + 5 = b are two equations that might be used to calculate how many soup cans and frozen dinners were purchased, respectively, where x and y stand for soup cans and frozen dinners, respectively, and a and b stand for the quantity of soup cans and frozen dinners.

The formula A=23.1 e^{0.0152t} models the population of a US state, A, in millions, t years after 2000.
a. What was the population of the state in 2000 ?
b. When will the population of the state reach 28.3 million?
a. In 2000 , the population of the state was ? million.
We want to study the population formula of a given US state according to exponential equation.
a) 23.1 millions.
b) in 2013 - 2014
What is exponential equation?
The exponential function may be a function denoted by f(x)=\exp or e^. Unless otherwise fixed, the term usually refers to the positive-valued operate of a true variable
Main body:
The population state is:
A = 23.1*e^(0.0153*t)
In millions.
Where t represents the number of years after 2000.
a) For the population at the year 2000, we need to evaluate the function at t = 0 (2000 is 0 years after 2000).
A(0) = 23.1*e^(0.0153*0) = 23.1
The population at year 2000 was 23.1 millions.
b) Now we want to solve:
A(t) = 28.3 = 23.1*e^(0.0153*t)
28.3/23.1 = e^(0.0153*t)
1.23 = e^(0.0153*t)
Now we can apply the natural logarithm to both sides:
ln(1.23) = ln( e^(0.0153*t) )
ln(1.23) = 0.0153*t
ln(1.23)/0.0153 = t = 13.5
Hence, 13.5 years after 2000 the population will be 28.3 million.

The meaning of congruent in Maths is addressed to those figures and shapes that can be repositioned or flipped to coincide with the other shapes. These shapes can be reflected to coincide with similar shapes.
Two shapes are congruent if they have the same shape and size. We can also say if two shapes are congruent, then the mirror image of one shape is the same as the other.
Two triangles are said to be congruent if their sides have the same length and angles have same measure. Thus, two triangles can be superimposed side to side and angle to angle.
In mathematics, the term "congruent" refers to figures and forms that may be flipped or rearranged to match up with other ones. These forms can be mirrored to produce related shapes. If two forms are similar in size and shape, they are congruent. We may also state that if two forms are congruent, then their mirror images are identical .Triangles that line up. A triangle is a closed polygon with three line segments that intersect at each of its three angles.
When the sides and angles of two triangles match, the triangles are said to be congruent. Thus, two triangles may be placed side by side and angle by angle on top of one another.
Since both the triangles are congruent this means the side , angles of both the triangles are equal

Answer: The correct answer is D, Lines are skew if and only if they are non-coplanar.
In geometry, lines are said to be skew if they are non-coplanar, meaning they do not lie in the same plane. They also do not intersect.
Option A is incorrect because angles can be supplementary (add up to 180 degrees) even if they do not form a linear pair (meaning they do not share a common vertex and a common side).
Option B is incorrect because Valentine's Day does not always fall in February. It is February 14th, but it could fall on a different month in a different year.

(b) Find the volume of the frustum.
(c) Find the surface area of the original pyramid.
The surface area of the frustum is 1744 square units
The volume of the pyramid is 2031.33 cube units.
What is a frustum of a pyramid?
By cutting the top of a typical pyramid, the frustum is created, which is a pyramid. Because of this, it is known as a truncated pyramid. The frustum of the pyramid is that portion of a pyramid that is cut through by a plane parallel to its base and lies between the vertex and the base.
a) First, we calculate the height of the frustum.
Let height be H
The base length be L1=24
Base width be W1=12
Top length is L2=14
To width be W2=13
Side height be C=13
Using the formula, H
[tex]H=\sqrt{ C^{2} - \frac{(L1-L2)^{2}}{2}}\\H=\sqrt{ 13^{2} - \frac{(24-14)^{2}}{2}}\\H=\sqrt{ 169 -50}\\H=\sqrt{119} \\H=11[/tex]
Now, the surface area of the frustum is LSA+area of bases of a frustum
Here, P1= perimeter of the base1 of the frustum
P2 is the perimeter of the base 2 of the frustum
[tex]L.S.A=\frac{1}{2} .(P1+P2).L \\=\frac{1}{2} .(72+42).24 \\=\frac{1}{2} .(114).24 \\=1368[/tex]
Now, S1 =area of base1 of frustum =288
S2= area of base 2 of frustum=98
TSA is given by LSA+area of bases of a frustum
=1368+288+98
=1724.
Therefore the surface area is 1724 square units.
b) Volume is given by

(b) At what velocity will it strike the ground? (Round your answer to three decimal places.)
(a) 2.79 seconds after its release the bag will strike the ground.
(b) At a velocity of 73.28 ft/second it will hit the ground.
What is velocity?
We are given that a balloon, rising vertically with a velocity of 16 feet per second, releases a sandbag at the instant when the balloon is 80 feet above the ground.
Assume the acceleration of the object is a(t) = −32 feet per second.
(a) For finding the time it will take the bag to strike the ground after its release, we will use the following formula;
[tex]s=u t+\frac{1}{2} a t^2[/tex]
Here, s= distance of the balloon above the ground =-80 feet
[tex]$\mathrm{u}=$[/tex] intital velocity =16 feet per second
[tex]$\mathrm{a}=$[/tex]acceleration of the object =-32 feet per second
[tex]$\mathrm{t}=$[/tex] required time
So, [tex]$s=u t+\frac{1}{2} a t^2$[/tex]
[tex]$$\begin{aligned}& -80=(16 \times t)+\left(\frac{1}{2} \times-32 \times t^2\right) \\& -80=16 t-16 t^2 \\& 16 t^2-16 t-80=0 \\& t^2-t-5=0\end{aligned}$$[/tex]
Now, we will use the quadratic D formula for finding the value of t, i.e;
[tex]t=\frac{-b \pm \sqrt{D}}{2 a}[/tex]
Here, a=1, b=-1, and c=-5
Also, [tex]$\mathrm{D}=b^2-4 a c=(-1)^2-(4 \times 1 \times-5)=21$[/tex]
So, [tex]$t=\frac{-(-1) \pm \sqrt{21}}{2(1)}$[/tex]
[tex]t=\frac{1 \pm \sqrt{21}}{2}[/tex]
We will neglect the negative value of t as time can't be negative, so;
[tex]t=\frac{1+\sqrt{21}}{2}=2.79 \approx 3 \text { seconds. }[/tex]
Hence, after 3 seconds of its release, the bag will strike the ground.
(b) For finding the velocity at which it hit the ground, we will use the formula;
v=u+a t
Here, v= final velocity
So,[tex]$v=16+(-32 \times 2.79)$[/tex]
v=16-89.28=-73.28 feet per second.
Hence, the bag will hit the ground at a velocity of [tex]$-73.28 \mathrm{ft} / \mathrm{second}$[/tex].
