-8a+32b in distributive property

Answer: To solve this problem, we can use the Pythagorean theorem. Let's call the depth of the treasure "d".

We can create a right triangle with the following sides:

The sensor on the boat is at the top of the triangle and is 200 meters away from the treasure diagonally.

The line from the sensor to the treasure, which we can call "x", is at a 25-degree angle from the surface of the water.

The line from the treasure to the ocean floor, which we can call "d", is perpendicular to the surface of the water.

Since we know that the angle of depression is 25 degrees, we can use tangent to find the length of x.

tan(25) = x/d

x = d * tan(25)

Now, we have two sides of a right triangle and can use the Pythagorean theorem to find d:

x^2 + d^2 = 200^2

d^2 = 200^2 - x^2

d^2 = 200^2 - (d * tan(25))^2

Solving for d, we find that d = 174.59 meters. Rounding to the nearest tenth of a meter, we get d = 174.6 meters.

The surface area of the given pyramid is 336 square feet. the correct answer would be an option (F) 336 ft².

A square pyramid's total surface area is the total area covered by its four triangular sides and square base. The formula may be used to calculate the total surface area of a square pyramid with slant height.

The surface area of a square pyramid = a² + 2al

The figure of the square pyramid is given in the question, as shown

The surface area of the pyramid = a² + 2al

Here a = 12 ft and l = 8 ft

Substitute the values of a = 12 ft and l = 8 ft in the formula,

The surface area of the pyramid = 12² + 2 × 12 × 8

The question seems incomplete, the correct question would be as:

Answer:Y = 7x – 16,

y = 2(2x – 5)

Step-by-step explanation:

he answer to the system of equations is (2,-2)

First, we can substitute in  for y in the other equation

This will give us

Next, we distribute the 2 throughout the parenthesis

Now we can solve for x. Begin by adding 16 to each side

Now we can subtract 4x from each side

Lastly, we can divide each side by 3

Now, we need to substitute in the value that we got for x into one of the equations to find the y value.

This becomes

So

This means that the solution to the system of equations is (2,-2)

True. Because they have comparable angles, the offered figures are comparable figures.

Similar figures are described as two shapes that share the same shape but differ in size. For instance, similar objects are depicted but are not consistent in different-sized images of a person, such as passport size, stamp size, etc. In geometry, two comparable shapes with different side lengths or sizes are those whose dimensions are equal or have a common ratio. Examples of these shapes are similar triangles, similar rectangles, and similar squares. Scale factor is the name given to the common ratio. The matching angles are also of equal measure.

If two figures are similar, then they are represented by the symbol ‘∼’. Let us say there are two triangles, ABC and PQR, which are similar, then they are represented as;

∆ABC ~ ∆ PQR

Now if the two triangles are similar to each then their corresponding sides should be in proportion. Hence,

AB/PQ = BC/QR = AC/PR

∠A = ∠P, ∠B = ∠Q, ∠C = ∠R

Since, we can see that the angles in both the given figures are exactly the same. Thus, the given figures are similar figures.

Alaskan huskies take 10h 34min.

Siberian huskies take 8h 45min.

Step-by-step explanation:

Alaskan huskies : 15km/h + 18min rest after 3h

18/3= 6min rest/h

1h= 60min

60/15= 4min/km

4*145= 580min

         = 9h 40min

There is three 3h in 9h 40min.

3*18= 54min

9h 40min+54min= 10h 34min

Siberian huskies : 20km/h + 30min rest after 2h

30/2= 15min rest/h

60/20= 3min/km

3*145=435min

The measure of arc CDE is, 154°

The measure of arc BC is, 26°

The measure of arc AB is, 90°

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Now, By the figure, we have;

⇒ ∠APE + ∠EPD = 180°

⇒ (25x + 15)° + (33x - 9)° = 180°

⇒ 58x + 6 = 180

⇒ 58x = 180 - 6

⇒ 58x = 174

⇒ x = 3

Hence, The measure of arc CDE is,

⇒ (20x + 4)° + (33x - 9)°

⇒ (20×3 + 4)° + (33×3 - 9)°

⇒ 64° + 90°

And, The measure of arc BC is,

⇒ 90° - (20x + 4)°

Area of the kite

perimeter of the kite

The area of the left over wood is given by

= area of the circle - area of the pentagon

area of the circle

= pi * r^2

= pi * 5^2

= 78.54 square cm

area of the pentagon

= 5/2 * a * 5

solving for a

360 / 5 = 72

72 / 2 = 36

cos 36 = a / 5

a = 5 cos 36 = 4

area of the pentagon = 5/2 * 4 * 5 = 50 sq cm

left over wood = 78.54 - 50 = 28.54 square cm

Area and perimeter of kite

area of kite = product of the two diagonals

length of one of the diagonals = 2 * KT = 2 * 12 = 24 cm.

The second diagonal

tan 30 = KT / x

x = 12 / tan30 = 20.78

the length = 12 + 20.78 = 32.78

area of the kite = 32.78 * 24 = 786.72 square cm

perimeter of the kite

= addition of the sides = 2(shorter side + longer side)

Using Pythagoras rule

shorter side = √(12² + 12²) = 16.97

longer side =  √(20.78² + 12²) = 24

perimeter = 2 (16.97 + 24) = 81.94 cm

If the height of a triangle is 2 cm more than base and the area of the triangle is 10 cm then the height is, 7 cm

An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².

The area of a triangle is given by the formula:

Area = (base x height) / 2

We are given that the area is 10 cm² and that the height is 2 cm more than the base.

Let's call the base "b".

Then, the height is "b + 2".

We can substitute these values into the area formula:

10 = (b x (b + 2)) / 2

Expanding the right side:

10 = (b² + 2b) / 2

Multiplying both sides by 2:

20 = b² + 2b

Subtracting b² from both sides:

20 - b² = 2b

Factoring the left side:

(10 - b)^2 = b²

Taking the square root of both sides:

|10 - b| = b

Adding b to both sides:

10 = 2b

Dividing both sides by 2:

5 = b

So, the base of the triangle is 5 cm and the height is b + 2 = 5 + 2 = 7 cm.

The unit tangent vector T and the curvature k is √2/3

Unit Tangent Vector and Curvature are two important concepts in vector calculus that are used to describe the behavior of curves in space.

To find the Unit Tangent Vector, we must first find the derivative of the curve. The curve is defined as (t) = <9 cos t, 9 sin t, √(3) t>, so taking the derivative with respect to t, we get:

d(t) / dt = < -9 sin t, 9 cos t, √(3) >

Next, we want to normalize this vector to get the Unit Tangent Vector, T. To do this, we divide the vector by its magnitude, which is given by:

=> √((-9 sin t)² + (9 cos t)² + (√(3))²)

=> √(81 + 81 + 3) = 9 √(3)

So, the Unit Tangent Vector is given by:

T = d(t) / dt / |d(t) / dt|

T = < -9 sin t / 9 √(3), 9 cos t / 9 √(3), √(3) / 9 √(3) >

T = < -sin t / √(3), cos t / √(3), 1 / 3 √(3) >

To find the Curvature, we use the formula:

k = |dT / dt|

where T is the Unit Tangent Vector and dT / dt is the derivative of the Unit Tangent Vector. To find dT / dt, we take the derivative of T with respect to t:

dT / dt = < cos t / √(3), -sin t / √(3), 0 >

Finally, the magnitude of dT / dt gives us the Curvature:

=> √((cos t / √(3))² + (-sin t / √(3))² + (0)²)

=> √(1 / 3 + 1 / 3) = √(2 / 3) / √(3)

So, the Curvature is given by:

k = √(2 / 3) / √(3)

k = √2 / 3

When a negative number is divided by a positive number, the result is always negative.

Let's use the example (-6) / 2 again. We can write this expression as:

(-6) / 2 = (-1) * 6 / 2

We can then simplify the expression on the right-hand side by multiplying -1 and 6, which gives us:

(-1) * 6 / 2 = -6 / 2

Now, we can divide 6 by 2, which gives us:

-6 / 2 = -3

So we see that the quotient is negative.

We can generalize this to any negative number divided by a positive number. Let's say we have a negative number -a and a positive number b. We can write the expression as:

(-a) / b = (-1) * a / b

Multiplying -1 and a gives us:

(-1) * a / b = -a / b

So we see that the quotient is negative, since -1 times a is negative, and dividing a negative number by a positive number results in a negative quotient.

Therefore, we can conclude that when a negative number is divided by a positive number, the result is always negative.
