Answer:

C. 39 ft²

Step-by-step explanation:

Area of the outer rectangle which includes the white triangle

= length x width

= 5 x 9

= 45  ft²

Area of the white triangle

= 1/2 x base x height

= 1/2 x 4 x 3

= 6 ft²

Area of shaded region
= Area of rectangle - Area of triangle

= 45 - 6

= 39 ft²

The triangle JKL is similar to triangle MNL by AA similarity and all three sides of the triangle are equal, so JKL = MNL.

One of the fundamental shapes in geometry is represented by the symbol Δ and consists of three connected vertices. Any one of a triangle's three sides can serve as its base, however typically the bottom side is used.

Given:

JK || MN and  L is the midpoint of JM,

As the line JK || MN  then,

∠ MNL = ∠ JKL (The alternate angle of the parallel line are equal)

∠ LMN = ∠ LJK (The alternate angle of the parallel line are equal)

∠ JLK = ∠ NLM (The corresponding  angle of the parallel line are equal)

Thus, all the sides will also be equal as the angles are equal.

Hence, the area will also be equal.

Step-by-step explanation:

The coordinates of the centroid of the triangle with the vertices at S(-2, 3), T(6, 7), and U(4, 1) is G(8/3, 11/3).

The center of the thing is represented by its centroid. The centroid of a triangle is the location where the triangle's three medians connect. The junction of all three medians is another definition for it. The median is a line that connects the middle of a side to the triangle's opposite vertex. The median is divided by the centroid of the triangle in a ratio of 2:1.

By averaging the x and y coordinates of each of the three vertices, we can get the centroid of the triangle. Therefore, the centroid formula may be written as G(x, y) = ((x1 + x2 + x3)/3, (y1 + y2 + y3)/3) in mathematics.

In the question, we are asked to find the coordinates of the centroid of the triangle with vertices at S(-2, 3), T(6, 7), and U(4, 1).

We know that the centroid is found using the centroid formula which is written as G(x, y) = ((x1 + x2 + x3)/3, (y1 + y2 + y3)/3).

Thus, the centroid G = ((-2 + 6 + 4)/3 (3 + 7 + 1)/3),

or, the centroid G = (8/3, 11/3).

Thus, the coordinates of the centroid of the triangle with the vertices at S(-2, 3), T(6, 7), and U(4, 1) is G(8/3, 11/3).

The miles will be around 303 miles, both Uhaul and Penske will have the same total cost.

To determine at what point both companies have the same total cost, we need to set up an equation.

Let x be the number of miles driven.
For Uhaul, the cost will be $50 + $0.99x.
For Penske, the cost will be $350.
Setting these two expressions equal to each other, we get:
$50 + $0.99x = $350
Simplifying this equation, we get:
$0.99x = $300
U-Haul: Cost_UH = 50 + 0.99 * miles

Penske: Cost_P = 350

Set the equations equal to each other to find the number of miles where the costs are equal.

50 + 0.99 * miles = 350

Solve for the number of miles.

0.99 * miles = 350 - 50 0.99 * miles = 300 miles = 300 / 0.99

Calculate the number of miles and round to the nearest whole number if needed.

miles ≈ 303

So,

At approximately 303 miles, both companies will have the same total cost for renting a truck for one day.
Dividing both sides by $0.99, we get:
x ≈ 303.03

It is important to note that this calculation assumes that the only cost for Uhaul is the rental fee and mileage charge, and does not include any additional fees or charges that may be incurred during the rental period.

It is also important to consider other factors such as the availability of trucks, customer service, and any additional services offered by the rental companies before making a final decision.

Darcy requires 24.14 gallons of paint to cover an area of 2716 feet².

Length of the house = 35 feet

width of the house = 28 feet

Height of the house = 6 feet

Total surface area = 2 l b + 2 b h + 2 h l

A = 2 (35) (28) + 2 (28) (6) + 2 (6) (35)

A = 1960 + 336 + 420

A = 2716 feet²

If he uses 2 coats of stain, the area he need to cover = 2 (2716) = 5432 feet²

Gallon of paint required = 5432 / 225 = 24.14 gallons.

1) The amplitude c+ is c+l

2) The expectation value is 0

3) The uncertainty ΔSX is √(3/7) c+.

Now, we know that any wave function can be written as a linear combination of two spin states (up and down), which can be written as:

Ψ = c+ |+> + c- |->

where c+ and c- are complex constants, and |+> and |-> are the two orthogonal spin states such that Sx|+> = +1/2|+> and Sx|-> = -1/2|->.

Hence, we can write the given wave function as:Ψ = c+|+> + i/√7|->

Now, we know that the given wave function has been defined in Sx basis, and not in the basis of |+> and |->.

Therefore, we need to write |+> and |-> in terms of |l> and |r> (where |l> and |r> are two orthogonal spin states such that Sy|l> = i/2|l> and Sy|r> = -i/2|r>).

Now, |+> can be written as:|+> = 1/√2(|l> + |r>)

Similarly, |-> can be written as:|-> = 1/√2(|l> - |r>)

Therefore, the given wave function can be written as:Ψ = (c+/√2)(|l> + |r>) + i/(√7√2)(|l> - |r>)

Therefore, we can write:c+|l> + i/(√7)|r> = (c+/√2)|+> + i/(√7√2)|->

Comparing the coefficients of |+> and |-> on both sides of the above equation, we get:

c+/√2 = c+l/√2 + i/(√7√2)

Therefore, c+ = c+l

The amplitude c+ is a real number and is equal to c+l

The expectation value of the operator Sx is given by: = <Ψ|Sx|Ψ>

Now, Sx|l> = 1/2|r> and Sx|r> = -1/2|l>

Hence, = (c+l*) + (c+l) + (i/√7) - (i/√7)(c+l*)= -i/√7(c+l*) + i/√7(c+l)= 2i/√7 Im(c+)

As c+ is a real number, Im(c+) = 0

Therefore, = 0

The uncertainty ΔSX in the state |Ψ> is given by:

ΔSX = √( - 2)

where = <Ψ|Sx2|Ψ>and2 = (<Ψ|Sx|Ψ>)2

Now, Sx2|l> = 1/4|l> and Sx2|r> = 1/4|r>

Hence, = (c+l*) + (c+l) + (i/√7) - (i/√7)(c+l*)= 1/4(c+l* + c+l) + 1/4(c+l + c+l*) + i/(2√7)(c+l* - c+l) - i/(2√7)(c+l - c+l*)= = 1/4(c+l + c+l*)

Now,2 = (2i/√7)2= 4/7ΔSX = √( - 2)= √(1/4(c+l + c+l*) - 4/7)= √(3/14(c+l + c+l*))= √(3/14 * 2c+)= √(3/7) c+

To find the angle between the vectors (-2, -1) and (3, -6), you can use the dot product and absolute value formulas. The angle between vectors is approximately 137.9 degrees.  

You can use the dot product of two vectors to find the angle between them. Denote the vectors as A = (-2, -1) and B = (3, -6). The inner product formula states that A · B = |A|. |B| cos θ, where |A| and |B| are the magnitudes of vectors A and B, and θ is the angle between them.

First we need to calculate the magnitude of the vector. \(|A| = \sqrt{((-2)^2 + (-1)^2)} = \sqrt{5}\) and |B| =\(\sqrt{(3^2 + (-6)^2) } = \sqrt{(9 + 36)} = \sqrt{45} = 3\sqrt{5}\). Then compute the dot product of A and B. A B = (-2)(3) + (-1)(-6) = -6 + 6 = 0.

Now we can rearrange the dot product formula to find the angle θ. \(0 = \sqrt{5} (3\sqrt{5} ) cosθ\). Simplification: cosθ = 0 / (\(\sqrt{5}) (3\sqrt{5} )\)) = 0. The cosine of θ is 0, so the angle θ is 90 degrees, or \(\pi\)radians. Therefore, the angle between vectors (-2, -1) and (3, -6) is approximately 90 degrees, or\(\pi\) radians.

To find the factors of the expression 12x^2 - 4x - 1, we can use the factor theorem. The factor theorem states that if a polynomial expression evaluates to zero when a certain value is substituted for the variable, then that value is a factor of the polynomial.

To determine if a certain value is a factor of the expression, we can use synthetic division. Synthetic division involves dividing the polynomial expression by the possible factor to check if the remainder is zero. If the remainder is zero, then the value is a factor.

Let's start by checking if x = 1 is a factor of the expression:

    1 | 12 - 4 - 1
      |     12   8
      |____________
       12   8   7

Since the remainder is not zero, x = 1 is not a factor of the expression.

Next, let's check if x = -1 is a factor of the expression:

   -1 | 12 - 4 - 1
      |    -12  16
      |____________
       12 -16  15

Again, the remainder is not zero, so x = -1 is not a factor of the expression.

Now, let's check if x = 2 is a factor of the expression:

    2 | 12 - 4 - 1
      |     24 40
      |____________
       12  20 39

Once again, the remainder is not zero, so x = 2 is not a factor of the expression.

Finally, let's check if x = -2 is a factor of the expression:

   -2 | 12 - 4 - 1
      |    -24 56
      |____________
       12 -28 55

As we can see, the remainder is not zero, so x = -2 is not a factor of the expression.

After checking all the possible factors, we can conclude that none of the values tested (1, -1, 2, -2) are factors of the expression 12x^2 - 4x - 1.
