Answer:

Step-by-step explanation:

Given data

Area A= \(36x -12 in^2\)

Width W= \(3x - 1 in\)

we know that the area A= length * width

i.e A= L*W

we can solve for the length by making it subject of the formula

L= A/W

L= \(\frac{36x -12}{3x - 1} in \\\\)

There are 3 internal nodes with degree 4 and 10 internal nodes with degree 3 in the tree t.

Let x be the number of internal nodes with degree 4, and y be the number of internal nodes with degree 3.

1. x + y = 13 (total internal nodes)
2. 4x + 3y = t - 1 (sum of degrees of internal nodes)

Since t has 24 leaves and 13 internal nodes, there are 24 + 13 = 37 nodes in total. So, t = 37 and we have:

4x + 3y = 36 (using t - 1 = 36)

Now, we can solve the two equations:

x + y = 13
4x + 3y = 36

First, multiply the first equation by 3 to make the coefficients of y equal:

3x + 3y = 39

Now, subtract the second equation from the modified first equation:

(3x + 3y) - (4x + 3y) = 39 - 36
-1x = 3

Divide by -1:

x = -3/-1
x = 3

Now that we have the value of x, we can find the value of y:

x + y = 13
3 + y = 13

Subtract 3 from both sides:

y = 13 - 3
y = 10

So, there are 3 internal nodes with degree 4 and 10 internal nodes with degree 3 in the tree t.

For all acute angles x such that the equation sin(2x)sin(3x) = cos(2x)cos(3x), the sum of the angles can be written as aπb in lowest terms, where a = 1 and b = 3 then, the answer is 1/3.

For all acute angles x satisfying the equation sin(2x)sin(3x) = cos(2x)cos(3x), we can use trigonometric identities to simplify the equation.

Using the double-angle identity for sine, we have:

sin(2x) = 2sin(x)cos(x)

Similarly, using the double-angle identity for cosine, we have:

cos(2x) = cos^2(x) - sin^2(x)

Applying these identities, the equation becomes:

2sin(x)cos(x)sin(3x) = cos^2(x)cos(3x) - sin^2(x)cos(3x)

Expanding further, we have:

2sin(x)cos(x)sin(3x) = cos(x)[cos^2(x)sin(3x) - sin^2(x)sin(3x)]

Dividing both sides by cos(x) (assuming cos(x) ≠ 0), we get:

2sin(x)sin(3x) = cos^2(x)sin(3x) - sin^2(x)sin(3x)

Now, we can factor out sin(3x) from both terms on the right side:

2sin(x)sin(3x) = sin(3x)[cos^2(x) - sin^2(x)]

Applying the Pythagorean identity cos^2(x) = 1 - sin^2(x), the equation simplifies to:

2sin(x)sin(3x) = sin(3x)(1 - 2sin^2(x))

If sin(3x) ≠ 0, we can cancel out sin(3x) from both sides:

2sin(x) = 1 - 2sin^2(x)

Rearranging the terms, we get a quadratic equation in terms of sin(x):

2sin^2(x) + 2sin(x) - 1 = 0

Solving this quadratic equation, we find two possible values for sin(x):

sin(x) = (-1 ± sqrt(3))/2

Since we are considering acute angles, we only take the positive value:

sin(x) = (-1 + sqrt(3))/2

To find the corresponding angles, we can use the inverse sine function:

x = arcsin((-1 + sqrt(3))/2)

Using a calculator, we find:

x ≈ π/3

Therefore, the only acute angle x satisfying the equation is x = π/3.

The sum of the angles can be written as aπb in lowest terms, where a = 1 and b = 3. Thus, the answer is 1/3.

Does the logical relationship between the premises and conclusion in the given argument hold true?

Yes, the logical relationship between the premises and conclusion in the given argument holds true.

To evaluate the given argument, we can break it down into its premises and conclusion:

Premises:

1.e ⊃ j (If e, then j)

2.b ⊃ q (If b, then q)

3.d ⊃ (j • ∼q) (If d, then (j and not q))

Conclusion:

(e • b) ≡ d ((e and b) if and only if d)

To determine the validity and cogency of the argument, we need to assess whether it is logically valid and whether its premises are true.

Validity: An argument is valid if the truth of its premises guarantees the truth of its conclusion. Let's analyze each premise:

1.e ⊃ j (If e, then j)

This premise asserts a conditional statement. If e is true, then j must also be true. This premise seems reasonable.

2.b ⊃ q (If b, then q)

Similar to the first premise, this premise asserts a conditional statement. If b is true, then q must also be true. This premise seems reasonable as well.

3.d ⊃ (j • ∼q) (If d, then (j and not q))

Once again, this premise states a conditional relationship. If d is true, then both j and not q must be true. This premise also seems reasonable.

Now let's consider the conclusion:

(e • b) ≡ d ((e and b) if and only if d) This conclusion states an equivalence, asserting that (e and b) is true if and only if d is true.

Given that all the premises are reasonable and logically valid, we can conclude that the argument is valid.

Therefore, the correct answer is:

c. Valid.

Answer:

Step-by-step explanation:

$ 3750 = truck rental; $125 per ton of sugar transported

C is cost; S is number of tons transported

Equation relating C to S would be a linear equation like y = mx + b

C = 125S + $3750

This equation would be graphed in the first quadrant only

you would start with your y-intercept at (0, 3750)

As x increases by 1, your y increases by 125 yielding these points:

(1, 3875) (2, 4000) (3, 4125) etc.

This shows that for each increase by one ton of sugar, the cost goes up $125

1)Cost of 1 ton = $ 2000

Cost of 2 ton = $3500

Cost of 3 ton = $5000

$ 1500 increase for each of ton of sugar being transported.

2) (1 , 2000) ; (2 , 3500)

The lower triangular 3×3 matrices x such that x³ is the zero matrix have the form : x = [0 0 0,g h 0,0 0 0] where g and h any real number.

To find all lower triangular 3×3 matrices x such that x³ is the zero matrix,  set up the equation x³ = 0 and solve for the elements of x. Let's represent a generic lower triangular matrix as:

x = [a b 0

d e f

g h i]

Multiplying x by itself three times,

x³ = [a b 0] × [a b 0] × [a b 0]

= [a²+bd ab 0]

[ad+be ae+bf b²]

[ag+bh ah+bh 0]

a²+bd = 0

ab = 0

ad+be = 0

ae+bf = 0

b² = 0

ag+bh = 0

ah+bh = 0

0 = 0

0 = 0

0 = 0

Step-by-step explanation:

the given equation defines a paraboloid that lies below the plane z=0. Specifically, it is situated above the xy-plane, which means that the z-values of all points on the surface are greater than or equal to zero.

we can break down the equation z=18-2x^2-2y^2. This equation represents a paraboloid with its vertex at (0,0,18) and axis of symmetry along the z-axis. The first term 18 is the z-coordinate of the vertex and the last two terms -2x^2 and -2y^2 determine the shape of the paraboloid.

Since the coefficient of x^2 and y^2 terms are negative, the paraboloid is downward facing and opens along the negative z-axis. Therefore, all points on the paraboloid have z-values less than 18. Additionally, since the paraboloid is situated above the xy-plane, its z-values are greater than or equal to zero.

the paraboloid defined by the equation z=18-2x^2-2y^2 is situated below the plane z=0 and above the xy-plane. Its vertex is at (0,0,18) and it opens along the negative z-axis.

Yes, it is possible to find a limit at a location where there is a hole in a graph , such as where a point has been removed or where a graph abruptly stops.

This is because the limit of a function is defined as the value that the function approaches as x approaches a given value. In the case of a hole in the graph, the limit is found by looking at the limit from the left, the limit from the right, and the general limit.

The limit from the left is the limit of the function as x approaches the hole from the left. The limit from the right is the limit of the function as x approaches the hole from the right. The general limit is the overall limit of the function at the point where the hole appears. By considering all of these limits, it is possible to determine the overall limit of the function at the point where the hole is present.

Answer: (-13.3, 8.6)

Step-by-step explanation:

First we want to identify which side of the graph A lands on compared to x. We see that A's X value is greater, meaning it is on the right side of M.

We can then start finding the opposite coordinate by finding the distance between the x and y values of A and M. We can do this By subtracting the M values from the A values:

\(x-distance = 2.3-(-5.5) = 7.8\\y-distance = -4.6 - 2 = -6.6\)

We then need to subtract these values from the M coordinate in order to find the coordinate B opposite of A:

\(B-xValue = -5.5 - 7.8 = -13.3\\B-yValue = 2 - (-6.6) = 8.6\)

From this, we can tell our coordinate B has the value: (-13.3, 8.6)

Hope this helps, if you need any clarification please let me know.

Step-by-step explanation:

given 2 points

A (xa, ya)

B (xb, yb)

their midpoint is

M ((xa + xb)/2, (ya + yb)/2)

in our case

A (2.3, - 4.6)

M(-5.5, 2)

so,

-5.5 = (2.3 + xb)/2

-11 = 2.3 + xb

xb = -13.3

2 = (-4.6 + yb)/2

4 = -4.6 + yb

yb = 8.6

The equation of the line passing through the point (2,-5) and is perpendicular to the line y = x/5-2 is y = -5x+5

The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

Given that, a line is passing through the point (2,-5) and is perpendicular to the line y = x/5-2, we need to find the equation of the line,

Let the name of line asked be a, and given line be b,

The general equation of the line is :- y = mx + c, where m is the slope and c is the y-intercept,

Therefore, In the line b, the slope m = 1/5

We know that, the lines which are perpendicular have negative reciprocals of their slopes,

Therefore, the slope of the line a = -5

Therefore, the equation of the line a, with c :-

y = -5x + c

To find c, put x = 2, and y = -5

-5 = -5(2) + c

-5 = -10 + c

c = 5

Therefore, the equation of the line a is :-

y = -5x+5

Hence, the equation of the line passing through the point (2,-5) and is perpendicular to the line y = x/5-2 is y = -5x+5
