The magnitude of vector is 8.24 and angle is 75.9638.
What is vector?
A vector could be a amount that not solely describes the magnitude however additionally describes the movement of an object or the position of an object with reference to another purpose or object.
Main body:
we know that the magnitude of vector is found out by,
| u | = \(\sqrt{i^{2}+j^{2} }\)
so here , u = 2i + 8j
|u| = \(\sqrt{2^{2} +8^{2} }\)
|u| = \(\sqrt{68}\)
|u| = 8.24
now to find the direction , angle
tan∅ = j/k
tan∅ = 8/2
∅ = tan⁻¹ (4)
∅ = 75.9638°
Hence , direction angle of the following vector is ∅ = 75.9638°

Which statement is true about the system x-3y=2 and y=x+6?
1. (8, 2) is not a solution to either equation, so it is not a solution to the system.
2. (8, 2) is a solution to one equation but not the other one, so it is a solution to the system.
3. (8,2) is a solution to both equations, so it is a solution to the system.
4. (8, 2) is a solution to one equation but not the other one, so it is not a solution to the system.
The true statement about the system of equations is the fourth one:
"(8, 2) is a solution to one equation but not the other one, so it is not a solution to the system."
Which statement is true about the system?The system of equations is:
x - 3y = 2
y = x + 6
We want to see which statement is true, all of them refer to the point (8, 2), so let's see if it is a solution of the system.
Replacing the values in the first equation we will get:
8 - 3*2 = 2
8 - 6 =2
2 = 2
For the second equation:
2 =8 + 6
2 = 14
This is false, so (8, 2) is not a solution of the second equation.
Then the true statement is:
" (8, 2) is a solution to one equation but not the other one, so it is not a solution to the system."

Answer:
Alisson
In November, Alisson was given $12.
Step-by-step explanation:
The normal amount given to Alisson each month = $x
If in November Alisson was given $9 more than thrice her usual amount of $x, it implies that she was usually given $3 ($9/3) per month because $9 is three times (thrice) than $3.
Therefore, Alisson's usual amount per month which is $x = $3
This implies that in November she was given $12 ($3 + $9), which was thrice more.
To check the correctness of the above reasoning, we recall that $12 is more by $9 than $3, and $9 is thrice than the $3 given to Alisson per month.

Solve the system of equations using the substitution or elimination method.

4x + 2y = -2
.
Show your work
Correct x and y
The solution to the system of equations is x = 1 and y = -3.
To solve the system of equations using the substitution or elimination method, let's start with the substitution method.
Given equations:
y = 4x - 7
4x + 2y = -2
We'll solve equation 1) for y and substitute it into equation 2):
Substituting y from equation 1) into equation 2):
4x + 2(4x - 7) = -2
4x + 8x - 14 = -2
12x - 14 = -2
Now, we'll solve this equation for x:
12x = -2 + 14
12x = 12
x = 12/12
x = 1
Now that we have the value of x, we can substitute it back into equation 1) to find y:
y = 4(1) - 7
y = 4 - 7
y = -3
Therefore, the solution to the system of equations is x = 1 and y = -3.

|w| + 19 < 14
the solution is: \(w < -5\) . Since all real numbers are either less than or greater than \(-5\) , the solution set for this inequality is "All reals".
What is the parameter for the real number?To solve for w in \(w + 19 < 14\) , we need to isolate w on one side of the inequality.
This means that any value of w that is less than \(-5\) would make the inequality true.
For example, \(w = -6\) is a solution because \(-6 + 19 < 14.\) Likewise, any value of w that is greater than or equal to -5 would make the inequality false. For example, \(w = -5\) is not a solution because \(-5 + 19 = 14\) .
Subtracting 19 from both sides of the inequality, we get:
\(w + 19 - 19 < 14 - 19\)

determine the maximum and minimum values of the function, at what values of x are they achieved? (without using a derivative)
\(y=\sin^3x-\sin^6x\)
The maximum and minimum values of the function is solved
Given data ,
We can find the maximum and minimum values of the function by taking the derivative of y with respect to x and setting it equal to zero.
y = (sin x)³ - (sin x)⁶
y' = 3(sin x)² cos x - 6(sin x)⁵ cos x
Setting y' equal to zero:
0 = 3(sin x)² cos x - 6(sin x)⁵ cos x
0 = 3(sin x)² cos x (1 - 2(sin x)³)
sin x = 0 or (sin x)³ = 1/2
If sin x = 0, then x = kπ for any integer k.
If (sin x)³ = 1/2, then sin x = (1/2)^(1/3) ≈ 0.866. This occurs when x = π/3 + 2kπ/3 or x = 5π/3 + 2kπ/3 for any integer k.
To determine whether these values correspond to a maximum or minimum, we can use the second derivative test.
y'' = 6(sin x)³ cos² x - 15(sin x)⁴ cos² x - 9(sin x)⁴ cos x + 6(sin x)⁵ cos x
y'' = 3(sin x)³ cos x (4(sin x)² - 5(sin x)² - 3cos x + 2)
For x = kπ, y'' = 3(0)(-3cos(kπ) + 2) = 6 or -6, depending on the parity of k. This means that these points correspond to a maximum or minimum, respectively.
For x = π/3 + 2kπ/3 or x = 5π/3 + 2kπ/3, y'' = 3(1/2)^(5/3) cos x (4(1/2)^(2/3) - 5(1/2)^(1/3) - 3cos x + 2). This expression is positive for x = π/3 + 2kπ/3 and negative for x = 5π/3 + 2kπ/3, which means that the former correspond to a minimum and the latter to a maximum.
Hence , the maximum value of the function is y = 27/64, which occurs at x = 5π/3 + 2kπ/3, and the minimum value is y = -1/64, which occurs at x = π/3 + 2kπ/3

Answer:
maximum: 0.25minimum: -2Step-by-step explanation:
You want the maximum and minimum values of the function ...
y = sin³(x) -sin⁶(x)
SolutionWhen we substitute sin³(x) = z, we have the quadratic expression ...
y = z -z² . . . . . a quadratic function
Adding and subtracting 1/4, we can put this in vertex form:
y = -(z -1/2)² +1/4
MaximumThis version of the function describes a parabola that opens downward and has a vertex at (z, y) = (1/2, 1/4). The y-value of the vertex represents the maximum value of the function.
The maximum value of y is 1/4.
MinimumThe sine function is a continuous function with a range of [-1, 1]. Then z will be a continuous function of x, with a similar range. We already know that y describes a function of z that is a parabola opening downward with a line of symmetry at z = 1/2. This means the most negative value of y will be found at z = -1 (the value of z farthest from the line of symmetry). That value of y is ...
y = (-1) -(-1)² = -1 -1 = -2
The minimum value of y is -2.

The exact solution of the equation 3x = 8 written as a logarithm is x = log3 8 and an approximate solution rounded to the nearest thousandth using the Change of Base Formula is x ≈ 1.893.
The equation given is 3x = 8.
Part A asks for the exact solution written as a logarithm. To solve for x, we can use logarithms. Taking the logarithm of both sides with base 3, we have:
log3(3x) = log3(8)
Using the power rule of logarithms, we get:
x log3(3) = log3(8)
Since log3(3) = 1, we have:
x = log3(8)
Therefore, the answer to Part A is (A) x = log3(8).
Part B asks for an approximate solution rounded to the nearest thousandth. We can use the change of base formula, which states that:
loga(b) = logc(b) / logc(a)
Using this formula with base 10, we get:
x = log10(8) / log10(3)
Using a calculator, we get:
x ≈ 1.892
Rounding to the nearest thousandth, we get:
x ≈ 1.892
Therefore, rounded to the nearest thousandth, the approximate solution is 1.892.

What is the slope of -x+ 5y = 10?
Answer:
Slope = 1/5
Step-by-step explanation:
Given equation,
→ -x + 5y = 10
The slope-intercept form,
→ y = mx + b
→ slope = m
Now the slope-intercept form is,
→ -x + 5y = 10
→ 5y = x + 10
→ y = (x + 10)/5
→ [ y = (1/5)x + 2 ]
Then the required slope will be,
→ y = (1/5)x + 2
→ Slope = m = 1/5
Hence, the required slope is 1/5.
Answer:
\(\textsf{Slope}=\dfrac{1}{5}\)
Step-by-step explanation:
\(\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}\)
Given equation:
\(-x+5y=10\)
To find the slope of the given equation, use algebraic operations to isolate y.
Add x to both sides of the equation:
\(\implies -x+5y+x=10+x\)
\(\implies 5y=x+10\)
Divide both sides of the equation by 5:
\(\implies \dfrac{5y}{5}=\dfrac{x+10}{5}\)
\(\implies y=\dfrac{1}{5}x+\dfrac{10}{5}\)
\(\implies y=\dfrac{1}{5}x+2\)
The coefficient of x is the slope of the equation.
Therefore, the slope of the given equation is ¹/₅.
