What exactly are expressions?
In mathematics, an expression is a combination of numbers, symbols, and operators (such as +, -, *, /, and ^) that represents a quantity or a relationship between quantities. It can be number, variable, or combination of both.
Expressions are used to represent mathematical operations, formulas, and relationships. They can be simple or complex, and they can be evaluated or simplified using mathematical rules and operations.
Now,
The correct relationship symbol that makes the statement true is ">" (greater than).
If a = b + c and c > 0, then a will always be greater than b. This is because adding a positive value (c) to b will increase the result (a) above the value of b.

find the polynomial with complex coefficients of the smallest possible degree for which 4i and 1 i are zeros and in which the coefficient of the highest power is 1.
The polynomial with complex coefficients of the smallest possible degree is found as: P(x) = x⁴ + 17x² + 16.
Explain the term complex coefficients?A complex coefficient is indeed a complex number that is a factor of some variable, as opposed to a complex number, which is a standalone entity.The given zeroes for the polynomial is-
4i and 1i.
From the conjugate zeroes theorem, for the polynomial having eal coefficients.
Then, -4i and -i is also the zeroes of the polynomial.
Thus, forming the polynomial P(x).
P(x) = (x + i)(x - i).(x + 4i)(x - 4i)
Using the property.
P(x) = (x² - i²).(x² - (4i)²)
We know that, i² = -1
P(x) = (x² + 1).(x² + 16)
Simplifying the equation;
P(x) = x⁴ + 17x² + 16
In which the coefficient of the highest power (x⁴) is 1.
Thus, the polynomial with complex coefficients of the smallest possible degree is found as: P(x) = x⁴ + 17x² + 16.

Which is the same as asking:
7 raised to what power equals 2,401?
7 raised to the power of 4 equals 2,401, and the exponent we were looking for is 4.
What is meant by power?
Power is a function that represents the number of times a base number is multiplied by itself. It is the rate at which work is done or energy is transferred, measured in watts.
What is meant by exponent?
An exponent is a mathematical notation used to indicate the number of times a quantity is multiplied by itself. It is written as a superscript and represents the power to which a number or expression is raised.
According to the given information
To find the value of the exponent that satisfies the equation 7ˣ = 2,401, we can take the logarithm of both sides of the equation with respect to base 7. This gives us:
log7(7ˣ) = log7(2,401)
x = log7(2,401)
Using a calculator, we can find that log7(2,401) is approximately 3. Therefore, the value of x that satisfies the equation 7ˣ = 2,401 is 3.
Alternatively, we could also use the fact that 2,401 is equal to 7⁴ - 2, which can be written as:
7⁴ - 2 = (7²)² - 2
= 49² - 2
= 2,401

Answer:
Step-by-step explanation:
A) if she starts with $61 in her saving account, write an inequality to show how much she wants to have.
- Starts with $61
- Wants AT LEAST $1500
$61 < $1500
B) how much does Kindra need to save?
If she already has $61 and she needs to get at least $1500, subtract to find out how much more she needs.
$1500 - $61 = $1,439 (she needs to save at least $1,439 more)

What is Iinear equatiοn?A Iinear equatiοn is a mathematicaI equatiοn that describes a straight Iine in a twο-dimensiοnaI pIane.

Frοm the first piece οf infοrmatiοn, we knοw that: x + y + z = 180
Frοm the secοnd piece οf infοrmatiοn, we knοw that: y + z = 5x
Frοm the third piece οf infοrmatiοn, we knοw that: z = y + 26
We can substitute the third equatiοn intο the secοnd equatiοn tο eIiminate z:
y + (y + 26) = 5x
2y + 26 = 5x
2y = 5x - 26
y = (5x - 26)/2
We can substitute this expressiοn fοr y intο the first equatiοn tο eIiminate y and z:
x + (5x - 26)/2 + (5x - 26)/2 + 26 = 180
2x + 5x - 26 + 26 = 360
7x = 360
x = 51.43
We can substitute this vaIue οf x back intο the expressiοn fοr y tο find y:
y = (5x - 26)/2
y = (5(51.43) - 26)/2
y = 92.85
FinaIIy, we can use the equatiοn z = y + 26 tο find z:
z = y + 26

Pythagoras theorem
If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem:
a² + b² = c²
If a is the missing side, then transform the equation to the form where a is on one side and take a square root:
a = √(c² - b²)
If b is unknown, then:
b = √(c² - a²)
If c is unknown, then:
c = √(a² + b²)

a=5, b=7 and c=?

5. El bloque de la figura se encuentra en reposo en el momento en que empiezan a actuar las fuerzas.

a. Encontrar el valor de la fuerza resultante.
b. Determina su aceleración.
C. Calcula la velocidad del bloque a los 5 segundos de movimiento.
The resultant force acting on the block is 47.6N.
The acceleration of the block will be 23.8 m/s².
The speed of the block after 5 seconds of movement is 119 m/s.
What is the resultant force?In this question, we need to make use of Newton's second law, hence:
resultant force = mass × acceleration
So, for question a. The value of the resultant force will be obtained by adding the two forces together:
resultant force = F₁ + F₂
= 25N + 22.6N
= 47.6N
b. Its acceleration will be:
acceleration = resultant force / mass
= 47.6N / 2kg
= 23.8 m/s²
c. The speed of the block after 5 seconds of movement will be:
Velocity (v) = u + at
velocity = initial velocity + acceleration x time
Based on the block was initially at rest, the initial velocity is 0.
Hence:
V = acceleration x time
= 23.8 m/s² x 5s
= 119 m/s
Hence the speed of the block after 5 seconds of movement will be: 119 m/s.

solve for x x2 - 11x - 60 = 0
The sοlutiοns tο the quadratic equatiοn \(x^2 - 11x - 60 = 0\) are x = 15 and x = -4.
What is quadratic equatiοn?Each quadratic prοblem can be sοlved using the quadratic fοrmula. The equatiοn is first changed tο have the fοrm \(ax^2+bx+c=0\), where a, b, and c are cοefficients.
Tο sοlve fοr x in the quadratic equatiοn x² - 11x - 60 = 0, we can use the quadratic fοrmula:
\(x = (-b \± \sqrt{(b^2 - 4ac))} / 2a\)
where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.
In this case, a = 1, b = -11, and c = -60. Substituting these values into the quadratic formula, we get:
\(x = (-(-11) \± \sqrt{((-11)^2 - 4(1)(-60)))} / 2(1)\)
Simplifying the expression under the square root, we get:
\(x = (11 \± \sqrt{(121 \+ 240))} / 2\\x = (11 \± \sqrt{(361)) / 2}\\x = (11 \± 19) / 2\)
So we have two solutions:
x = (11 + 19) / 2 = 15
x = (11 - 19) / 2 = -4
Therefore, the solutions to the quadratic equation x² - 11x - 60 = 0 are x = 15 and x = -4.

A projectile is thrown into the air. The equation y=-3x² - 12x + 96 represents the path of the projectile, where x represents the amount of time in seconds. How long is the projectile in the air, in seconds?
As this is when it hits the ground, the projectile is in the air for 6 seconds.
Physically speaking, the missile would have been at ground level two seconds prior to launch if x were negative. Thus, we disregard the unfavorable option.
What is a projectile?Objects that are thrown, shot, or launched with a certain initial velocity and then move against the forces of gravity and air resistance are known as projectiles. Projectiles can be anything from arrows and bullets to rocks and water balloons. Typically, a bow, slingshot, gun, or cannon is used to fire them. When projectiles are launched, gravity, air resistance, and other forces influence their trajectories.
from the question:
We must discover the moment the missile strikes the ground in order to calculate how long it was in the air. The height of the missile above the earth would be zero at that point.
Thus we must resolve the following equation:
y = -3x² - 12x + 96 = 0
We can use the quadratic formula to solve this equation in the quadratic form:
x = (-b ± √(b² - 4ac)) / 2a
where a = -3, b = -12, and c = 96.
Plugging in these values, we get:
x = (-(-12) ± √((-12)² - 4(-3)(96))) / 2(-3)
x = (12 ± √(144 + 1152)) / (-6)
x = (12 ± √1296) / (-6)
x = (12 ± 36) / (-6)
So, the solutions are:
x = -2 or x = 6
Physically speaking, the missile would have been at ground level two seconds prior to launch if x were negative. Thus, we disregard the unfavorable option.
As a result, the missile is in the air for 6 seconds before it strikes the earth.
