Part A: Student B's work does not provide a proper verification of the identity.

Part B: Neither Student A nor Student B properly verified the given identity.

Part A:

Upon reviewing Student A's work, it becomes evident that they did not verify the identity properly. Student A's work does not follow the logical steps required to prove the given identity. They seem to have made errors in manipulating the trigonometric functions, resulting in an incorrect conclusion. Therefore, Student A's verification is incorrect.

Part B:

Student A's work did not successfully prove the given identity, so we cannot identify any identities used in their verification. However, we can discuss two identities that could potentially be used to prove the given identity.

Reciprocal Identity:

One possible identity that could be used is the reciprocal identity of cotangent and cosecant:

cosec(x) = 1/sin(x)

cot(x) = 1/tan(x)

Pythagorean Identity:

Another relevant identity is the Pythagorean identity:

sin²(x) + cos²(x) = 1

These identities could be applied in the process of verifying the given identity (cot x)(cos x) = csc x − sin x. However, it is important to note that the exact steps and techniques used to prove the identity may vary depending on the approach taken.

If you have a value of 50 berries picked, you would make 165 dollars.

This triangle is not a right triangle because the sum of the squares of the two smaller sides is not equal to the square of the largest side.

To determine if a triangle is a right triangle, you can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two smaller sides is equal to the square of the largest side.

In this case, we can compare the squares of the sides with lengths of 33 km and 72 km, and the square of the side with length 78 km:

33^2 + 72^2 = 5184 + 5184 = 10368

78^2 = 6084

Since 10368 is not equal to 6084, we can conclude that this triangle is not a right triangle.

The 11-4 skills practice areas of regular polygons and composite figures involve finding the areas of different geometric shapes using specific formulas and methods.

To find the area of regular polygons, you can use the formula (1/2) x apothem x perimeter.

For composite figures, you can break the shape into smaller, more manageable shapes like rectangles, triangles, or circles, and then calculate the area of each component before adding them together.

Hence, The 11-4 skills practice areas of regular polygons and composite figures teach you to find areas using the appropriate formulas and methods, improving your geometry understanding and problem-solving abilities.

If money 0.08 or 8% compound interest annually, then Marilou makes a lot of money of 834,323.90 annually.

Compound Interest rate:

Compound interest is interest on savings calculated on the original principal amount or money and accrued interest from previous periods.

The power of "interest plus interest" or compound interest is thought to have its origins in 17th century Italy. This will increase faster than simple interest, which is calculated on the principal only.

Capitalization increases capital at an accelerated rate, the more periods of capitalization, the greater the capitalization.

Because the payments are made monthly and the interest rate is compounded annually, we must convert the interest rate from annual compound to monthly compound.

Given that:

Php = 10000/ month

Duration 10 years.

Now,

If the interest rate is 8% annually then,

8% = 1 + 0.08 =1.08¹⁾¹²

The value of the rectangular cuboid will be 6,355.725 mm³.

Given that:

Length, L = 7.50 x 10² mm

Width, W = 102.1 mm

Height, H = 0.083 mm

A cuboid's volume is determined by multiplying its length, breadth, and height. A cuboid is a six-sided, three-dimensional geometry where the length, breadth, and height correspond to the three perpendicular sides. Add the length, breadth, and height together to obtain the volume.

The volume of the cuboid is calculated as:

V = 7.50 x 10² mm x 102.1 mm x 0.083 mm

V = 6,355.725 mm³

Thus, the value of the rectangular cuboid will be 6,355.725 mm³.

\(\\ \sf{:}\!\implies -10x+y=29\)

\(\\ \sf{:}\!\implies y=10x+29\)

Hence

Step-by-step explanation:

Plug in known values

\(13.4 = 5.825\sqrt[3]{\frac{3590}{p}}\\\)

Divide both sides by 5.825

\(2.3004 = \sqrt[3]{\frac{3590}{P}}\\\)
Cube both sides

\(12.1738 = \frac{3590}{P}\)

Multiply both sides by P

\(12.1738P = 3590\)

Divide both sides by 12.1738

\(P = 294.895\)

Round to nearest hp

\(P = 295\)

So if you look at the radical, it's possible for it to be mistake for a square root, and not a cube root. This was Daniels mistake, so his steps were

\(13.4 = 5.825\sqrt[3]{\frac{3590}{p}}\\\)

Divide both sides by 5.825

\(2.3004 = \sqrt[3]{\frac{3590}{P}}\\\)

Square both sides

\(5.29197 = \frac{3590}{P}\)

Multiply both sides by P

\(5.29197P = 3590\)

Divide both sides by 5.29197

\(p\approx 678.385\)

He also probably rounded during his steps, which would explain how he got 679 instead of 678 when rounding in the final, but either way his answer is completely off, and this is due to him mistakenly thinking the cube root was a square root.

Answer:

6,0

Step-by-step explanation:

the dilation moves points from A to B

in this case we're moving point T

point T has coordinates 2,0 to start with (A)

Now let's move it to B

To do so, we need to apply the calculation

(x,y) => (3x,3y)

Substitute in point T:

(2,0) => (3x,3y)

(2,0) => (3(2),3(0))

(2,0) => (6,0)

Answer:

Step-by-step explanation:

Answer:

i think x = -1, y = 1

Step-by-step explanation:

3+2x-y=0

so 3+2x = y

-3-7y=10X

-3-7(3+2x) = 10x

-3-21-14x = 10x

-24-14x = 10x

-14x-10x = 24

-24x = 24

x = -1

3+2x = y

so 3+2(-1) = y

3+(-2) = y

1 = y

SO x = -1 and y = 1

Altitude and perpendicular bisector of a side are always perpendicular to a side of a triangle.

How do triangles work?

A triangle is a three-sided polygon with three vertices. The angles of the triangle are formed by the three sides' end-to-end connections at a point.

               The triangle's three angles add up to a total of 180 degrees.

In a triangle, what is the altitude?

The perpendicular line drawn from a triangle's vertex to its opposite side is the definition of a triangle's altitude.

                       The altitude forms a right-angle triangle with the base and is also referred to as the triangle's height.
