Which of the following is an inequality which involves one or more rational
expressions?
a. Exponential inequality
b. Linear inequality
c. Logarithmic inequality
d. Rational inequality
The inequality in which involves one or more rational expressions is Rational inequality.
What is inequality?
Using the terms greater than, larger than or equal to, less than, or less than or equal to as a declaration of the order connection between two integers or algebraic expressions is known as inequality. Economic inequality comes in many forms, most notably wealth inequality measured by the distribution of wealth and income inequality measured by the distribution of income (the amount of money people are paid) (the amount of wealth people own). There are significant forms of economic inequality amongst various groups of people in addition to economic disparity between nations or states.
An inequality with a rational expression is said to be rational. Inequalities with rational expressions, such as 32x>1, 2xx34, 2x3x6x, and 142x23x, are referred to as rational inequalities.

The answer is d. Rational inequality, which includes fractions with polynomials. Other options involve exponential, linear, or logarithmic functions, without rational expressions as in inequalities.
The right choice is d. Rational inequality. An objective disparity includes at least one sane articulations, which are portions with polynomials in the numerator and denominator. These disparities can be settled by finding the basic places where the normal articulation is indistinct or changes sign.
The arrangement includes deciding the stretches where the disparity turns out as expected in view of the indication of the judicious articulation in those spans. Interestingly, dramatic, direct, and logarithmic disparities include various kinds of numerical capabilities.
Remarkable imbalances contain dramatic terms, direct disparities incorporate straight capabilities, and logarithmic imbalances contain logarithmic capabilities. Each kind of imbalance has its own qualities and strategies for settling, however just objective disparities straightforwardly manage levelheaded articulations including parts of polynomials.

Scallops eject water from their shells to provide a thrust force. A 29 g scallop accelerates from rest straight up to escape a predator, reaching a
speed of 4.10 m/s in 0.15 s. What is the ratio of the net force to the weight of the scallop (Fnet/Weight) for this motion? (Hint: Remember that
grams are a measurement of mass, not force). Round to three decimal places and express in terms of SI units.
The ratio of the net force to the weight of the scallop (F net/Weight) for this motion exists 792.657 Newtons.
What is meant by net force?The net force exists the vector sum of all the forces that act upon an object. The total of all forces exerted on an object is known as the net force. A mass can accelerate due to net force. A body is subject to another force whether it is at rest or in motion. When there are a lot of forces acting on a system, the term "net force" is employed.
Given, mass = 29g, speed = 4.10 m/s , Time = 0.15 s
Acceleration (a ) = (final speed - initial speed)/time taken
= 4.10 - 0/ 0.15 = 27.333 m/s/s
F = m × a = 29 g × 27.33 m/s
= 792.657 Newtons
Therefore, the ratio of the net force to the weight of the scallop (F net/Weight) for this motion exists 792.657 Newtons.

Recall that the sum of the measures of the angles of a triangle is 180°. In the triangle below, angle Chas the same measure as angle B, and angle measures 42° less than angle B.
Find the measure of each angle.
The measure of each angles a,b and c are 32°, 74° and 74° respectively.
What is triangle?
Three edges and three vertices define a triangle as a polygon. One of geometry's fundamental shapes is this one. The symbol for an ΔABC triangle is A, B, and C.
Any three points determine a distinct triangle and a distinct plane in Euclidean geometry when they are non-collinear (i.e. a two-dimensional Euclidean space). To put it another way, each triangle is contained in a plane, and there is only one plane that includes that particular triangle. All triangles are contained in one plane if and only if all geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except as otherwise specified, the subject of this article is triangles in Euclidean geometry, more specifically, the Euclidean plane.
Let angle b be x
Therefore angle c will also be x [as given b and c are equal] and angle a will be x - 42°.
Now as we know that the sum of the measures of the angles of a triangle is 180° therefore,
x + x + x - 42° = 180°
=> 3x = 222°
=> x = 74° which is angle b and c
and angle a is (74 - 42)° =32°

What is the Factor Theorem?The Factor Theorem states that a polynomial function with roots(also called zeros) [tex]x_1, x_2, \codts, x_n[/tex] is given by the following rule.
[tex]f(x) = a(x - x_1)(x - x_2) \cdots (x - x_n)[/tex]
In which a is the leading coefficient of the polynomial, determining if it is positive(a positive) or negative(a negative).
Considering a leading coefficient of a = 1, the zeros of the polynomial are given as follows:
Zero at x = -1, hence [tex]x_1 = -1[/tex].Zero at x = 2 - 3i, hence [tex]x_2 = 2 - 3i[/tex].Zero at x = 2 + 3i, which is the conjugate of x = 2 - 3i, since if a complex number is a root of a polynomial, it's conjugate also is, hence [tex]x_3 = 2 + 3i[/tex].Hence the polynomial is given by:
f(x) = (x + 1)(x - 2 + 3i)(x - 2 - 3i)
f(x) = (x + 1)[(x - 2)² - (3i)²]
f(x) = (x + 1)(x² - 4x + 13), as (3i)² = 9i² = 9(-1) = -9, -(-9) = 9.

The total probability that a king and pawn are selected without replacement is 1 / 31 .
The area of mathematics known as probability primarily deals with numerical(fractions or decimals) representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Sample space = 32 (16 black and 16 white pieces)
number of kings in the set = 2
Probability that a king is selected first
P(king) = 2 ÷ 32 = 1 / 16
Now the total number of pieces left = 32 - 1 = 31
number of pawns = 8+8 =16
Probability that a pawn is selected = 16 ÷ 31
P(pawn) = 16/31
Now the total probability that a king and pawn are selected without replacement = P(king) × P(pawn) = 1/16 × 16/31 = 1 / 31
Therefore the required probability is 1 / 31 .

What is the shortest length of fence that the Ranch owner can use?
Length of fence =

In linear equation, 3464.1016 feet is the shortest length of fence that the Ranch owner can use.
What is linear equation definition and example?
An equation in which there is only one variable is known as a linear equation in one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with just one possible value. One such linear equation in one variable is 9x + 78 = 18.Let L represent the length of the field.
Let W represent the width of the field.
Let F represent the length of fence needed.
L*W=500000
2L+3W=F Both length sides+both width sides+ fence across the width.
Let's look at the first equation again:
L*W=500000
W=(500000/L)
Now we can substitute (500000/L) for W in the second equation.
2L+3(500000/L)=F
2L+1500000/L=F
Now we have a function. We can input any length, and we'll know length needed. But how can we find the length needed so that F is as small as it can be? If you know derivatives, there's an exact way. The next easiest way to do it is to graph.
Manner 1: Derivative
Set the derivative to zero...when the length stops going down and starts coming back up, it'll be at it's lowest point.
2L+1500000^-1=F
F'=2-1500000^-2
0=2-1500000^-2
1500000/(L^2)=2
1500000=2L^2
1500000=L^2
L=866.025
Now, we know that L=500000/W
so 866.025=500000/W
W=500000/866.025
W=577.35027 feet.
Now,
2L+3W=2(866.025)+3(577.35027)
Minimum fencing needed: 3464.1016 feet.

Answer:
difference = 6 feet 5 inches
Step-by-step explanation:
The longest shot put throw by a boy is given as 25 feet 8 inches . The longest shot put throw by a girl is given as 19 feet and 3 inches. The number of times the longest shot put throw by a boy is greater than by a girl can be computed as follow.
The question asked us to find the difference between the throw. The difference between the throw is the boy throw minus the girls throw. Mathematically,
The longest boys throw = 25 feet 8 inches
The longest girls throw = 19 feet 3 inches
difference = The longest boy throw - The longest girl throw
difference = 25 feet 8 inches - 19 feet 3 inches
difference = 6 feet 5 inches

The world's population grew from approximately 2.6 to 5.2 billion between 1952 and 1987.
Assuming that the population growth during this time period followed an exponential model, calculate the
average annual population growth rate of the world between 1952 and 1987 as a percentage.
Answer:
R=100%
Step-by-step explanation:
Here
Increased population (Pt) = 5.2-2.6 = 2.6
Time = 1987-1952
Rate of increase=?
By formula
Pt = P(1-R/100)^t
2.6=2.6(1-R/100)^35
1=(1-R/100)^35
0^35 = (1-R/100)^35
0=1-R/100
0= 100-R
R=100%
so the average annual population growth rate of the world between 1952and1987 is 100%
