ln(144) can be written in terms of ln(3) and ln(4) as:
ln(144) = 4 ln(2) + 2 ln(3) ≈ 4 ln(1.386) + 2 ln(3) ≈ 2.7726 + 2 ln(3)
We can use the logarithmic property that states that ln(a * b) = ln(a) + ln(b) to rewrite ln(144) in terms of ln(3) and ln(4).
First, we can find the prime factorization of 144:
[tex]144 = 2^4 * 3^2[/tex]
Using the property above, we can rewrite ln(144) as:
[tex]ln(144) = ln(2^4 * 3^2) = ln(2^4) + ln(3^2)[/tex]
Now, we can use another logarithmic property that states that ln(aᵇ) = b * ln(a) to simplify ln(2⁴) and ln(3²):
ln(144) = 4 ln(2) + 2 ln(3)
Therefore, ln(144) can be written in terms of ln(3) and ln(4) as:
ln(144) = 4 ln(2) + 2 ln(3) ≈ 4 ln(1.386) + 2 ln(3) ≈ 2.7726 + 2 ln(3)

What are the coordinates of the fourth vertex of the rectangle
The coordinates of the fourth vertex of the rectangle are (2, 5).
To find the fourth vertex of the rectangle, we need to first determine which sides of the triangle are opposite and parallel to each other. We can see that the two points (-6,3) and (-6,5) lie on a vertical line, which means they are opposite and parallel to each other.
Similarly, the two points (-6,3) and (2,3) lie on a horizontal line, which means they are also opposite and parallel to each other. The fourth vertex of the rectangle must lie at the intersection of these two lines.
The point (-6,3) is the lower left corner of the rectangle, and the point (2,3) is the lower right corner. The distance between these two points is 2 - (-6) = 8. Since the opposite sides of a rectangle are congruent, the distance between the other two corners (-6,5) and the fourth vertex must also be 8.
Since the two points (-6,3) and (-6,5) are on a vertical line, the y-coordinate of the fourth vertex must also be 5. We can find the x-coordinate by moving 8 units to the right of (-6,3), since the rectangle is parallel to the x-axis. Thus, the fourth vertex must be located at the point:
(x,y) = (-6+8, 5)
= (2, 5)

Calculate the volume of the parallelepiped determined by the vectors in R3:
u= i - 2j +3k
v=2i+k
w=4j
The volume of the parallelepiped determined by the vectors u, v, and w is 20.
To calculate the volume of the parallelepiped determined by the vectors u, v, and w, we need to use the scalar triple product. The scalar triple product of three vectors is defined as the dot product of one vector with the cross product of the other two vectors. In this case, the volume of the parallelepiped is given by:
Volume = |u . (v x w)|
Where "." represents the dot product and "x" represents the cross product.
First, let's calculate the cross product of v and w:
v x w = (2i + k) x (4j) = 8k - 4i
Next, let's take the dot product of u and the result of the cross product:
u . (v x w) = (i - 2j + 3k) . (8k - 4i) = -4 + 24 = 20
Finally, we take the absolute value of the result to get the volume of the parallelepiped:
Volume = |20| = 20
Therefore, the volume of the parallelepiped determined by the vectors u, v, and w is 20.

1. Find all real solution(s) to each equation algebraically: (a) - n + √(6n + 19) = 2 (Remember to check your solutions.) (b) x^4 - 20x^2 + 64 = 0
the real solutions to this equation are x = 2√2 and x = -2√2.
Solution:
(a) -n + √(6n + 19) = 2
To find the solution algebraically, we need to isolate the radical on one side of the equation and then square both sides to get rid of the radical.
-n = 2 - √(6n + 19)
(-n - 2)^2 = (2 - √(6n + 19))^2
n^2 + 4n + 4 = 4 - 4√(6n + 19) + 6n + 19
n^2 - 2n - 19 = -4√(6n + 19)
(n^2 - 2n - 19)^2 = (-4√(6n + 19))^2
n^4 - 4n^3 - 18n^2 + 76n + 361 = 96n + 304
n^4 - 4n^3 - 114n^2 + 76n + 57 = 0
This is a quartic equation that can be solved using the Rational Root Theorem or by factoring. However, this equation does not have any real solutions. Therefore, there are no real solutions to this equation.
(b) x^4 - 20x^2 + 64 = 0
This equation can be factored as:
(x^2 - 8)^2 = 0
x^2 - 8 = 0
x^2 = 8
x = ±√8
x = ±2√2
Therefore, the real solutions to this equation are x = 2√2 and x = -2√2.
Remember to check your solutions by plugging them back into the original equation and seeing if they make the equation true.

d women are released, how many hours a day will the remaining women have to work
to produce c articles each day? (There’s an attached photo to this !)
The equation (bd)/(b-d) = c can be used to determine how many hours a day the remaining women must work in order to produce the same number of articles each day, when some of the women have been released.
What is an equation?An equation is an expression used to relate two or more quantities, usually by using mathematical operators such as addition, subtraction, multiplication and division. An equation typically has an equal sign (=) as its central element, with the left and right sides of the equation representing the two sides of the equation.
The answer to this question can be determined by using the following equation: (bd)/(b-d) = c. This equation is a simple ratio that takes into account the number of hours the women work per day (b), the number of women released (d), and the number of articles produced each day (c).
For example, if a factory had 10 women working 8 hours a day and produced 100 articles each day, and 5 of those women were released, then the equation (8 x 5) / (8-5) = 100 would determine that the remaining women must work 12.5 hours per day in order to produce the same number of articles.
In conclusion, the equation (bd)/(b-d) = c can be used to determine how many hours a day the remaining women must work in order to produce the same number of articles each day, when some of the women have been released.

find the value of largest rectangular parallelopiped that can be incribed in the ellipsoid
The value of the largest rectangular parallelopiped that can be inscribed in the ellipsoid is (2a)*(2b)*(2c).
To find the value of the largest rectangular parallelopiped that can be inscribed in the ellipsoid, we need to use the formula for the volume of a parallelopiped. The formula is:
V = l*w*h
Where V is the volume, l is the length, w is the width, and h is the height.
Since we are looking for the largest rectangular parallelopiped, we need to maximize the volume. This can be done by finding the maximum values of the length, width, and height.
The maximum values of the length, width, and height can be found by using the semi-axes of the ellipsoid. The semi-axes of the ellipsoid are given by:
a = √(x^2/a^2 + y^2/b^2 + z^2/c^2)
Where a, b, and c are the semi-axes of the ellipsoid, and x, y, and z are the coordinates of the point on the surface of the ellipsoid.
The maximum values of the length, width, and height can be found by setting the derivatives of the volume with respect to x, y, and z to zero:
∂V/∂x = 0
∂V/∂y = 0
∂V/∂z = 0
Solving these equations will give us the maximum values of the length, width, and height. Once we have these values, we can plug them into the formula for the volume of a parallelopiped to find the largest volume.
The largest volume of the rectangular parallelopiped that can be inscribed in the ellipsoid is given by:
V = (2a)*(2b)*(2c)
Where a, b, and c are the semi-axes of the ellipsoid.

Maricopa's Success scholarship fund receives a gift of $ 85000. The money is invested in stocks, bonds, and CDs. CDs pay 5.5 % interest, bonds pay 5.2 % interest, and stocks pay 6.4 % interest. Maricopa Success invests $ 20000 more in bonds than in CDs. If the annual income from the investments is $ 4780 , how much was invested in each account?
Maricopa Success invested $ in stocks.
Maricopa Success invested $ in bonds.
Maricopa Success invested $ in CDs.
To solve this problem, we can use a system of equations. Let's represent the amount invested in stocks as x, the amount invested in bonds as y, and the amount invested in CDs as z.
The first equation we can create is the total amount invested:
x + y + z = 85000
The second equation is the difference between the amount invested in bonds and CDs:
y - z = 20000
The third equation is the total interest earned:
0.064x + 0.052y + 0.055z = 4780
We can use substitution to solve this system of equations. Let's rearrange the second equation to solve for y:
y = z + 20000
We can then substitute this value of y into the first equation:
x + (z + 20000) + z = 85000
Simplifying gives us:
x + 2z = 65000
Now, let's substitute the value of y into the third equation:
0.064x + 0.052(z + 20000) + 0.055z = 4780
Simplifying gives us:
0.064x + 0.107z = 3780
We can now use the first and third equations to solve for x and z. Let's rearrange the first equation to solve for x:
x = 65000 - 2z
We can then substitute this value of x into the third equation:
0.064(65000 - 2z) + 0.107z = 3780
Simplifying gives us:
4160 - 0.128z + 0.107z = 3780
Combining like terms gives us:
-0.021z = -380
Solving for z gives us:
z = 18095.24
We can now use this value of z to solve for y:
y = z + 20000 = 18095.24 + 20000 = 38095.24
And finally, we can use the value of z to solve for x:
x = 65000 - 2z = 65000 - 2(18095.24) = 28809.52
So, Maricopa Success invested $28809.52 in stocks, $38095.24 in bonds, and $18095.24 in CDs.

The quadrilateral formed from the points P(7, -3), Q(0,3), R(-9,5), and S(-2,-1) is a rhombus.
To find the desired slopes and lengths, we can use the slope formula and the distance formula. The slope formula is (y₂ - y₁)/(x₂ - x₁) and the distance formula is √((x₂ - x₁)² + (y₂ - y₁)²).
Slope of PQ = (3 - (-3))/(0 - 7) = 6/(-7) = -6/7
Slope of QR = (5 - 3)/(-9 - 0) = 2/(-9) = -2/9
Slope of RS = (-1 - 5)/(-2 - (-9)) = (-6)/(7) = -6/7
Slope of SP = ((-3) - (-1))/(7 - (-2)) = (-2)/(9) = -2/9
Length of PQ = √((0 - 7)² + (3 - (-3))²) = √(49 + 36) = √85
Length of QR = √((-9 - 0)² + (5 - 3)²) = √(81 + 4) = √85
Length of RS = √((-2 - (-9))² + ((-1) - 5)²) = √(49 + 36) = √85
Length of SP = √((7 - (-2))² + ((-3) - (-1))²) = √(81 + 4) = √85
Since the opposite slopes are equal and all of the lengths are equal, the quadrilateral is a rhombus.

Prove that, for a, b, and c ∈ Z, a > b and c > 0 =⇒ ac
> bc (part 3 of Proposition 2)
Our assumption is false
We can prove this statement by contradiction. Suppose a > b and c > 0 but ac < bc.
Since a > b, then a - b > 0. Multiplying both sides by c > 0 gives (a - b)c > 0.
We can then add bc to both sides to get (a - b)c + bc > bc.
Since we assumed that ac < bc, then (a - b)c < 0, and thus (a - b)c + bc < bc, which contradicts the previous result.
Therefore, our assumption is false, and we can conclude that for a, b, and c ∈ Z, a > b and c > 0 =⇒ ac ≥ bc.
