If Laura uses both talk and text right in equation for the cost, C what we do know of sending text and talking M minutes
A. Equation:
B. how much will it cost Laura to send 4 text and talk for 13 minutes
C. if Laura wants to send 18 texts and only has eight dollars how many minutes can she talk? Will this use all her money? if not how much money will she have left?
D. Solve equation for T.
A. The equation is given as C = 0.1T + 0.05M
B. It will cost Laura $1.05 to send 4 texts and talk for 13 minutes.
C. Laura will have $1.80 left after sending 18 texts and talking for 124 minutes.
D. The equation for T is T = (C - 0.05M) / 0.1.
Step by step explanationA. The equation for the cost, C, of sending both texts and talking for M minutes is:
C = 0.1T + 0.05M
where T is the number of texts sent.
This equation assumes that each text costs 10 cents and each minute of talk time costs 5 cents.
B. To calculate the cost of sending 4 texts and talking for 13 minutes, we can use the equation from part A:
C = 0.1T + 0.05M
C = 0.1(4) + 0.05(13)
C = 0.4 + 0.65
C = 1.05
Therefore, it will cost Laura $1.05 to send 4 texts and talk for 13 minutes.
C. To determine how many minutes Laura can talk if she wants to send 18 texts and only has eight dollars, we need to use the equation from part A and solve for M:
C = 0.1T + 0.05M
8 = 0.1(18) + 0.05M
8 = 1.8 + 0.05M
6.2 = 0.05M
M = 124
Therefore, Laura can talk for 124 minutes if she wants to send 18 texts and has eight dollars.
This will cost her $6.20, which is less than the amount of money she has, so she will have some money left over.
subtract the cost of talking and texting from the amount of money she has:
Money left = 8 - 6.20
Money left = 1.80
Therefore, Laura will have $1.80 left after sending 18 texts and talking for 124 minutes.
D. To solve the equation from part A for T, we can rearrange the terms:
C = 0.1T + 0.05M
0.1T = C - 0.05M
T = (C - 0.05M) / 0.1
Therefore, the equation for T is T = (C - 0.05M) / 0.1.

a positive divided by a negative become?
A positive divided by a negative always results in a negative quotient.
Let's use the example 8 / (-2) again. We can write this expression as:
8 / (-2) = 8 / (-1) * 2
We can then simplify the expression on the right-hand side by multiplying -1 and 2, which gives us:
8 / (-1) * 2 = -8 / 2
Now, we can divide 8 by 2, which gives us:
-8 / 2 = -4
So we see that the quotient is negative.
We can generalize this to any positive number divided by a negative number. Let's say we have a positive number a and a negative number -b. We can write the expression as:
a / (-b) = a / (-1) * b
Multiplying -1 and b gives us:
a / (-1) * b = -a / b
So we see that the quotient is negative, since -1 times b is negative, and dividing a positive number by a negative number results in a negative quotient.
Therefore, we can conclude that when a positive number is divided by a negative number, the result is always negative.

What is circumference ?Circumference is the distance around the perimeter of a circular object. It is defined as the length of the circle that is found by multiplying the diameter of the circle by π (pi), which is approximately equal to 3.14.
The formula for the circumference of a circle is given by:
C = 2πr,
To calculate the circumference of the circular garden, we can use the formula:
C = 2πr
where C is the circumference, π is the mathematical constant pi (approximated as 3 in this case), and r is the radius. Plugging in the given values, we have:
C = 2 x 3 x 70
= 420 feet
Now, since the flowers are spaced every 4 feet, we can divide the circumference by 4 to find the number of flowers needed:
number of flowers = C / 4
= 420 / 4
= 105
Therefore, 105 flowers spaced every 4 feet are needed to surround a circular garden with a 70-foot radius.

What are the 5 most common Pythagorean triples?
The 5 most common Pythagorean triples are ( 3 , 4 , 5 ) , ( 5 , 12 , 13 ) ,
( 6 , 8 , 10 ) , ( 9 , 12 , 15 ) , and ( 15 , 20 , 25 ) .
Pythagorean triples:
Any three positive integers that completely satisfy the Pythagorean theorem is considered a Pythagorean triple number. According to the theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a right triangle. A Pythagorean triple consists of the three sides of a right triangle. In this article, you will learn how to create multiple Pythagorean triples.
A Pythagorean triple consists of the three natural numbers a, b, c such that a² + b² = c². These triples are usually written as (a, b, c), examples
(3, 4, 5) are well known. If (a, b, c) is a Pythagorean triple, then (ka, kb, kc) is also a Pythagorean triple for all natural k. A primitive Pythagorean triplet is a triplet in which a, b, and c are coprime (i.e., have no common divisor greater than 1). For example, (3, 4, 5) is a basic Pythagorean triple, but (6, 8, 10) is not.
A triangle whose sides form a Pythagorean triple is called a Pythagorean triangle and is necessarily a right triangle.
This name comes from the Pythagorean theorem, which states that the side lengths of each right triangle satisfy the formula a² + b² =c². A Pythagorean triple gives the length of three integers of the sides of a right triangle. However, right triangles whose sides are not integers do not form a Pythagorean triple. For example, a triangle with sides a = b = 1 and c = √2 but, (1,1,2) is not a Pythagorean triple because √2 is not an integer. Also, the numbers 1 and √2 do not have a common multiple because √2 is irrational.

A charge 5. 00 nc is placed at the origin of an xy-coordinate system, and a charge -2. 00 nc is placed on the positive x-axis at x = 4. 00 cm. A third particle, of charge 6. 00 nc is now placed at the point x = 4. 00 cm , y = 3. 00 cm.
The x-component of the total force exerted on the third charge by the other two charges is equal to k * (30.00 nC * 4.00 cm / 5.00 cm + 12.00 nC).
Force is a physical quantity that measures the influence of one object on another. It is a vector quantity, meaning it has both magnitude and direction.
Let's use Coulomb's Law to calculate the x-component of the total force exerted on the third charge by the other two charges. The x-component of the total force is just the sum of the x-components of the forces exerted by each of the two charges.
First, we'll calculate the force exerted by the 5.00 nC charge at the origin. The direction of this force will be towards the third charge, so the angle θ is the arctangent of the ratio of the y-coordinate of the third charge and the x-coordinate of the third charge. That is, θ = arctan(3.00 cm / 4.00 cm). Using Coulomb's Law, we have:
F = k * q1 * q2 / r²,
where k is the Coulomb constant, q1 and q2 are the magnitudes of the charges, and r is the distance between them. For this case,
=> r = √(4.00 cm² + 3.00 cm²) = 5.00 cm.
Thus,
F = k * 5.00 nC * 6.00 nC / 5.00 cm^2 = k * 30.00 nC.
Fx = F * cos(θ) = k * 30.00 nC * cos(arctan(3.00 cm / 4.00 cm))
Fx = k * 30.00 nC * 4.00 cm / 5.00 cm.
Next, we'll calculate the force exerted by the -2.00 nC charge on the x-axis. This force will be in the negative x-direction, so the angle θ is 180 degrees. Thus,
F = k * -2.00 nC * 6.00 nC / 4.00 cm^2 = -k * 12.00 nC.
Fx = F * cos(180) = -k * 12.00 nC * cos(180) = k * 12.00 nC.
Finally, we add up the x-components of the forces exerted by each charge to get the total x-component of the force:
Fx = k * 30.00 nC * 4.00 cm / 5.00 cm + k * 12.00 nC
Fx = k * (30.00 nC * 4.00 cm / 5.00 cm + 12.00 nC).
Complete Question:
A charge of 5.00 nC is placed at the origin of the xy - coordinate system, and a charge of -2.00 nC is placed on the positive x-axis at x = 4.00 cm. A third particle, of charge 6.00 nC is now placed at the point x = 4.00 cm, y = 3.00 cm.

Alan makes the statement about the intersection point of a system of inequalities. Explain why Alan’s statement is incorrect.
The intersection point is always a solution to a system of
inequalities because that is where the two lines meet
Answer: No, Alan's statement is incorrect!
Step-by-step explanation:
The intersection point of a system of inequalities is not always a solution. It only becomes a solution if the two lines meet at the same point and the lines are not parallel. If the two lines are parallel, then they will not intersect and thus the intersection point will not be a solution.
Step-by-step explanation:
if there is an intersection point (the lines are not parallel), there is still the question, if the points on the line are included in the solution or not.
if not, then the intersection point is not part of the solution either.
this is controlled by the absence of presence of the "or equal" part of the inequality.
>= greater than or equal
<= less than or equal
if the inequality is only
> greater than
< less than
the lines are just delimiters, but their points are not part of the solution. and therefore not the intersection point either.

The quadratic-like polynomial x⁶ + 8 has no real roots, that is, it has two complex roots. (Correct choice: B)
What polynomial cannot be factored using real numbers?
In this problem we must determine what polynomial has no real roots. From real algebra we remember that any polynomial of the form x²ⁿ + a², where a is a positive real number, has no real numbers. That is, the factor form of the polynomial is shown below:
(xⁿ + i a) · (xⁿ - i a)
In other words, any polynomial of the form x²ⁿ + a², a > 0, has two complex roots. Now, by direct comparison, we conclude that polynomial x⁶ + 8 has no real roots.
