Step-by-step explanation:
write a system of two equations in two unknowns. do not solve the system. in a certain village, there are w wizards and n necromancers for a total of 30 magical people. there are six more necromancers than there are wizards. write a system of equations that determines the numbers of wizards and the number of necromancers. w n
Answers
The system of equations that describes the number of wizards and necromancers in the village is: w + n = 30 n = w + 6.
Let's denote the number of wizards as 'w' and the number of necromancers as 'n'.
From the problem, we know that there are a total of 30 magical people in the village. Therefore, our first equation is simply: w + n = 30. Additionally, we're told that there are six more necromancers than wizards. This means that:
n = w + 6.
We can substitute this second equation into the first to get: w + (w + 6) = 30. Simplifying this equation gives us: 2w + 6 = 30
This is as far as we can simplify the equations without solving for 'w' and 'n'. These equations can be used to determine the values of 'w' and 'n' by solving the system of equations using algebraic methods.

True or False if f 00(2) = 0, then (2, f(2)) is an inflection point of the curve y = f(x)
Answers
The statement is false. If f''(2) = 0, it does not necessarily imply that (2, f(2)) is an inflection point of the curve y = f(x).
To understand why, let's first review the concept of inflection points. An inflection point is a point on a curve where the concavity changes. More precisely, it is a point where the second derivative changes sign. If the second derivative changes from positive to negative or from negative to positive at a specific point, that point is an inflection point.
However, the value of the second derivative alone does not determine whether a point is an inflection point. It only provides information about the concavity at that point. For a point to be an inflection point, the concavity must change on either side of that point.
Let's consider an example to illustrate this. Suppose we have a function f(x) = x^4. Taking the first derivative, we find f'(x) = 4x^3. Taking the second derivative, we find f''(x) = 12x^2. If we evaluate f''(2), we get f''(2) = 12(2)^2 = 48. In this case, f''(2) ≠ 0.
Now, if we examine the behavior of f(x) = x^4 near x = 2, we see that the function is concave up both to the left and to the right of x = 2. The concavity does not change at x = 2. Therefore, (2, f(2)) is not an inflection point.
This example demonstrates that even if the second derivative f''(2) happens to be zero, it does not guarantee that (2, f(2)) is an inflection point. Additional analysis is necessary to determine the concavity on either side of the point.
In summary, the statement "If f''(2) = 0, then (2, f(2)) is an inflection point of the curve y = f(x)" is false. The second derivative being zero at a specific point is not sufficient to conclude that the point is an inflection point. Inflection points require a change in concavity on either side of the point.

pls solve: 6 - 2/9x = 8
Answers
Answer:
x = -9
Step-by-step explanation:
6 - 2/9x = 8
Subtract 6 from each side
6-6 - 2/9x = 8-6
-2/9 x = 2
Multiply each side by -9/2 to isolate x
-9/2 * -2/9x = 2*-9/2
x = -9
Answer:
\(x = - 9\)
Step-by-step explanation:
\(6 - \frac{2}{9} x = 8 \\ - \frac{2}{9} x = 8 - 6 \\ - \frac{2}{9} x = 2 \\ - 2x = 2 \times 9 \\ - 2x = 18 \\ \frac{ - 2x}{ - 2} = \frac{18}{ - 2} \\ x = - 9\)
ABCD is a cyclic quadrilateral inscribed in the circle \Gamma with AB as diameter. Let E be the intersection of the diagonals AC and BD. The tangents to \Gamma at the points C,D meet at P. Prove that PC=PE.
Answers
Answer:
Given that AB is the diameter of the circle, we have ∠ACB = 90°, and similarly ∠ADB = 90°.Since ABCD is a cyclic quadrilateral, we have ∠AEB + ∠CED = 180°.Also, since AC and BD are diagonals of the quadrilateral, they intersect at point E.Consider the tangent to the circle at point C. Since PC is also a tangent to the circle, we have ∠CAB = ∠PCB.
Carl collects coins compulsively, but he only likes quarters and dimes. Carl currently has 125 coins for a total of $26.00. How many of each coin does Carl have? What are the two equations?
Answers
Answer
x + y = 125 ----- equation 1
0.25x + 0.1y = 26 --- equation 2
Step-by-step explanation:
let x represents quarter and y represents dimes
According to the question, quarter and dimes made up the total coins Carl has
Carl has 125 worth of coins
quarter + dime = coin
x + y = 125 ----------- equation 1
The coins are worth a total of $26
one coin = 0.25 quarters
one coin = 0.1 dimes
0.25x + 0.1y = 26 ----- equation 2
Hence, the two equations are
x + y = 125 ----- equation 1
0.25x + 0.1y = 26 --- equation 2

A triangle has two sides measuring 8 and 15. The included angle is 33°. What is the length of the side opposite the 33° angle?
Answers
Answer:
Measure of the side opposite to the angle measuring 33° is 9.37 unit
Step-by-step explanation:
If a, b and c are the sides of a triangle,
And 'a' = 8
b = 15
Measure of the Included angle C = 33°
By applying cosine rule in the given triangle,
c² = a² + b² - 2abcos(C)
c² = 8² + (15)² - 2(8)(15)cos(33°)
= 64 + 225 - 201.28
= 87.72
c = √87.72
c = 9.266
≈ 9.27
Therefore, measure of the side opposite to the angle measuring 33° is 9.37 units

I need help with part b.Answer of Part A: (dy(x))/(dx) = (2 x - sqrt(3) y)/(sqrt(3) x - 4 y)
Answers
Given the equation:
\(x^2-\surd3xy+2y^2=12\)You know that the derivative with respect to "x" is:
\(\frac{dy}{dx}=\frac{2x-\sqrt[]{3}y}{\sqrt[]{3}x-4y}\)• The Slope-Intercept Form of the equation of a line is:
\(y=mx+b\)Where "m" is the slope and "b" is the y-intercept.
In this case, to find the slope of the tangent line, you need to substitute the coordinates of the point given in the exercise, into the derivative found in Part A. Then, knowing that:
\(\begin{gathered} x=\sqrt[]{3} \\ y=3 \end{gathered}\)You get:
\(m=\frac{2(\sqrt[]{3})-\sqrt[]{3}(3)}{\sqrt[]{3}(\sqrt[]{3})-4(3)}=\frac{2\sqrt[]{3}-3\sqrt[]{3}}{3-12}=\frac{-\sqrt[]{3}}{-9}=\frac{\sqrt[]{3}}{9}\)Substitute the slope and the coordinates of the point into this equation:
\(y=mx+b\)Then:
\(3=(\frac{\sqrt[]{3}}{9})(\sqrt[]{3})+b\)Solve for "b":
\(\begin{gathered} 3=(\frac{\sqrt[]{3}}{9})(\sqrt[]{3})+b \\ \\ 3=\frac{(\sqrt[]{3})^2}{9}+b \\ \\ 3=\frac{3}{9}+b \end{gathered}\)\(\begin{gathered} 3-\frac{3}{9}=b \\ \\ b=\frac{8}{3} \end{gathered}\)Therefore, you can write this equation of the tangent line:
\(y=\frac{\sqrt[]{3}}{9}x+\frac{8}{3}\)• In order to find the equation of the line normal line at the same point, you need to
remember that it is perpendicular to the tangent line.
By definition, the slopes of perpendicular lines are opposite reciprocal. Therefore, knowing the slope of the tangent line, you can determine that the slope of the normal line is:
\(m_{\text{normal}}=-\frac{9}{\sqrt[]{3}}\)You can simplify as follows:
\(m_{\text{normal}}=-\frac{9}{\sqrt[]{3}}\cdot\frac{\sqrt[]{3}}{\sqrt[]{3}}\)\(\begin{gathered} m_{\text{normal}}=-\frac{9\sqrt[]{3}}{3} \\ \\ m_{\text{normal}}=-3\sqrt[]{3} \end{gathered}\)Knowing the point given in the exercise and the slope of the normal line, you can substitute them into this equation and solve for "b":
\(y=mx+b\)Then, you get:
\(\begin{gathered} 3=(-3\sqrt[]{3)}(\sqrt[]{3})+b \\ \\ 3=-3(\sqrt[]{3)}^2+b \end{gathered}\)\(\begin{gathered} 3=-3(3)+b \\ 3+9=b \\ b=12 \end{gathered}\)Finally, knowing the slope and the y-intercept, you can write the equation of the normal line:
\(y=-3\sqrt[]{3}x+12\)Hence, the answer is:
• Equation of the tangent line:
\(y=\frac{\sqrt[]{3}}{9}x+\frac{8}{3}\)• Equation of the normal line:

Answers
The probability that x equals 7 is 1/9. The 63 possible outcomes is equally likely, the probability of getting a sum of 7 is given by the ratio of favorable outcomes to total outcomes, which is 7/63.
To find the probability that the sum of three dice equals 7, we need to determine the number of outcomes that satisfy this condition.
There are several ways to achieve a sum of 7:
(1, 2, 4), (1, 3, 3), (2, 2, 3), (2, 3, 2), (3, 1, 3), (3, 2, 2), and (4, 1, 2).
Therefore, there are 7 possible outcomes that result in a sum of 7.
Since each of the 63 possible outcomes is equally likely, the probability of getting a sum of 7 is given by the ratio of favorable outcomes to total outcomes, which is 7/63.
This simplifies to 1/9.
Thus, the probability that x equals 7 is 1/9.

Answers
Answer:
D: (1,2)
Step-by-step explanation:
To find the translation vector, we need to determine the difference between corresponding coordinates of the original triangle and the translated triangle.
Let's denote the original triangle's vertices as A(0, 0), B(3, 0), and C(0, 4). The corresponding vertices of the translated triangle are A'(1, 2), B'(4, 2), and C'(1, 6).
To find the translation vector, we subtract the coordinates of each vertex in the original triangle from the coordinates of the corresponding vertex in the translated triangle.
Translation vector for point A:
x-component: 1 - 0 = 1
y-component: 2 - 0 = 2
Translation vector for point B:
x-component: 4 - 3 = 1
y-component: 2 - 0 = 2
Translation vector for point C:
x-component: 1 - 0 = 1
y-component: 6 - 4 = 2
Therefore, the translation vector is (1, 2).

A passenger train left the station and traveled toward Las Vegas at an average speed of 55mph. A cattle train left at the same time and traveled in the opposite direction with an average speed of 65mph. Which equation best represents this situation when the trains are 960 mi apart?
A - 65x - 55(2) = 960
B - 65x - 55x = 960
C - 65x + 55(2) = 960
D - 65x + 55x = 960
E - 65(2) + 55x = 960
Answers
Answer:
The answer is b
Step-by-step explanation:
The distance traveled by the passenger train and the cattle train is equal to the total distance between them, which is 960 miles. Let x be the time (in hours) traveled by the passenger train and cattle train. Then, the equation that represents this situation is:
55x + 65x = 960
Simplifying the left-hand side of the equation, we get:
120x = 960
Dividing both sides by 120, we get:
x = 8
Therefore, the correct equation is:
B - 65x - 55x = 960
