Answer:
P = 3.75x - 7
Step-by-step explanation:

Carl deposited $1220 in a bank that pays 9% interest compounded monthly find the amount he will have at the end of 3 years
The amount that Carl will receive after 3 years is $ 27,146.49 when he invested $ 1220 at 9 % compound interest monthly.
We are given that:
Principal amount = P = $ 1,220
Compound interest rate = r = 9 % monthly
Time = 3 years = 3 × 12 months = 36 months.
The amount after 3 years will be given by:
Amount = 1,220 ( 1 + 0.09)³⁶
Amount = 1,220 ( 1.09 )³⁶
Amount = 1220 ( 22.25 )
Amount = $ 27,146.49
Therefore, we get that, the amount that Carl will receive after 3 years is $ 27,146.49 when he invested $ 1220 at 9 % compound interest monthly.

What is meant by exponents?An exponent (also known as a power or degree) indicates the number of times the base is multiplied by itself. For example,'has an exponent of 5 and a base of. This means that variable would be multiplied 5 times by itself. This can also be thought of as to a fifth power.
Some properties of the exponents are given as-
Zero Property: Any non-zero real number raised to a power of zero equals one.Negative Property: Whatever nonzero real number raised to either a negative power is one divided by the same number raised to a positive power.Product Property: When two exponents that have the same nonzero real number base are multiplied, the result is the sum of the exponents that have the same base.Quotient Property: When two exponents that have the same nonzero real number base are divided, the result is the difference of the exponents that have the same base.Now, for the stated question;
The given expression is;
=> 3x⁻¹ = 24
Divide both sides by 3.
=> x⁻¹ = 8
Taking the reciprocal on both sides.
=> 1/x⁻¹ = 1/8
This 1/x⁻¹ can be written as x.
=> x = 1/8

4. What is the net force when a pair of balanced forces acts on an object?
A.It is less than one of the forces.
B.It equals one of the forces.
C.It is zero.
D.It is greater than both forces.
C.It is zero.
Step-by-step explanation:The net force is the sum of all of the forces exerted on an object.
Identifying Forces
Force is measured in newtons, which is shortened to N. Additionally, force will always have a direction, like 5N up or 3N to the left.
Sometimes force will be negative to represent direction. A force moving down or to the left might be negative because moving down or to the left on an axis moves towards negative numbers.
Net Force
As stated above, the net force is the sum of all of the forces acting on an object. For example, if one object is being moved 5N to the left and 4N to the right, the net force will be 1N to the left.
On the other hand, if the forces are balanced, like 5N on both the left and right, then the forces cancel out. This leaves a net force of 0.
Consider the midpoint of the diagonal AC.
A (3, -1) and C(7,-5)
The midpoint of diagonal AC is (5,-3).
Given A(3,-1) and C(7,-5)
Let the midpoint of diagonal AC be represented by P (say). Then the coordinate of P can be calculated by using the formula listed below:
let us suppose the coordinates of A be (a, b) and B be (c, d) and P is the midpoint of AC then the coordinate of P will be (a+c/2, b+d/2).
Now, by using the above formula, we get
x-coordinate of P be (3+7)/2 = 10/2 = 5
y-coordinate of P be (-1+(-5))/2 = -6/2 = -3
∴ The coordinate of midpoint of AC i.e., P be (5, -3).
Hence, the midpoint of diagonal AC is (5,-3).

In Exercises 11-14, find m/1, m/2, and m/3. Explain your reasoning.
The measure of angles 1, 2 and 3 for fig in 11. are 100°, 80° and 100°. And for part 12. are 80°, 80° and 100° respectively.
For 11. part:
Considering two parallel lines l and m cut by a transversal p,
If two parallel lines are intersected by a transversal, each pair of interior angles on the same side of the transversal is supplementary.
m∠1 + 80° = 180°
m∠1 = 180° - 80°
m∠1 = 100°
Similarly, m∠1 + m∠2 = 180°
⇒ 100° + m∠2 = 180°
⇒m∠2 = 180° - 100°
⇒m∠2 = 80°
and also, m∠2 + m∠3 = 180°
⇒ 80° + m∠3 = 180°
⇒m∠3 = 180° - 80°
⇒m∠3 = 100°
Therefore, m∠1 = 100°, m∠2 = 80° and m∠3 = 100°.
For 13. part:
m∠3 = 100° (vertically opposite angle)
Now, let us suppose the angle adjacent to ∠3 be x then, m∠x will be simply equal to
m∠3 + m ∠x = 180° (Linear pair property.)
100° + m ∠x = 180°
m ∠x = 180° - 100°
m ∠x = 80°
Now, from the figure we can clearly see that,
m∠1 = m∠2 = m ∠x = 80°(Corresponding angles are equal.)

Simplify each number. (-243)¹/₅
The given expression contains a fractional exponent and would be simplified through solving for it.
The reciprocal of power associated with the base is the degree of the radical signs.
For example: ∜7=7^1/4
In the given expression, there are two considerations. The number 243 has a power of 1/5, and the negative sign or say -1 also has a power of 1/5.
As a general rule, if the denominator of the fractional exponent is an odd number, as 5 in this case, the negative sign is extracted from the radical. Another way to look at it is -1 raised to any odd power would be -1.
Hence, (-243)^¹/₅ =-(243)^¹/₅
Factorizing the term,
243=3*3*3*3*3
Which can be expressed as 3^5
Hence,
-(243)^1/5=-(35)^1/5
As we know that (a^b)^c=a^bc, thus,
-(3^5^)1/5=-(3^5*1/5)= -(3^1)=-3

Can someone explain what it means by creating a dot plot showing a uniform distribution?
A uniform distribution has the data values evenly distributed throughout the range of the data. A bimodal distribution has two very common data values seen in a dot plot or histogram as distinct peaks.
A Dot Plot, also called a dot chart or strip plot, is a type of simple histogram-like chart used in statistics for relatively small data sets where values fall into a number of discrete bins (categories). A dot plot is similar to a bar graph because the height of each “bar” of dots is equal to the number of items in a particular category.
A dot plot is a graphical display of data using dots: Dot Plot is a graph for displaying the distribution of quantitative variable where each dot represents a value. For whole numbers, if a value occurs more than once, the dots are placed one above the other so that the height of the column of dots represents the frequency for that value.

Write a relation that is not a function, but whose inverse is a function.
The relation that is not a function, but whose inverse is a function are:
for every x in the domain of f, f -1[f(x)] = x, and
for every x in the domain of f -1, f[f -1(x)] = x
An inverse function is a characteristic that undoes the movement of another characteristic. A feature g is the inverse of a characteristic f if whenever y=f(x) then x=g(y). In different words, applying f and then g is the equal aspect as doing not anything. we are able to write this in terms of the composition of f and g as g(f(x))=x.
A few capabilities do not have inverse functions. for instance, remember f(x) = x2. There are numbers that f takes to four, f(2) = 4 and f(-2) = four. If f had an inverse, then the fact that f(2) = 4 might mean that the inverse of f takes four again to 2.
To discover the inverse function of an algebraic relation in terms of x and y, simply interchange the variables x and y, and resolve the equation for y. as an example, to discover the inverse of a relation y = x3, interchange x, and y after which clear up it for y. Then we get x = y3 ⇒ y = x1/3.
An inverse version can be represented by means of the equation xy=k or y=kx. this is, y varies inversely as x if there are a few nonzero steady k such that, xy=k or y=kx in which x≠0,y≠0 . assume y varies inversely as x such that xy=3 or y=3x.
