Find the 15th term of the geometric sequence 9, 18, 36, ...

Answer:

C. complementary

Michel-Eugène Chevreul discovered that placing complementary colors next to each other can create the greatest contrast and vibrancy in color perception. This is because complementary colors are located opposite each other on the color wheel and, when placed side by side, they enhance each other and create a strong visual impact. For example, placing yellow next to violet or blue next to orange can create a dynamic and eye-catching effect. In contrast, placing tertiary colors (colors made by mixing primary and secondary colors) or arbitrary colors next to each other may not create as much contrast or visual interest. Overall, understanding color theory and the relationships between different colors can be helpful for creating visually appealing designs, artworks, or other color-based projects.

The triangles are not similar. Triangle EFG and Triangle QRS are not similar. ΔEFG not ~ ΔQRS

From the question, we are to determine if the given triangles are similar

From one of Triangle similarity theorems, AA (or AAA) or Angle-Angle Similarity theorem.

The Angle-Angle similarity theorem states that If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other

In the given diagram,

In triangle EFG

m ∠E = 104°

m ∠F = 45°

m ∠G = 180° - (104° + 45°) = 31°

In triangle QRS

m ∠R = 100°

m ∠Q = 45°

m ∠S = 180° - (100° + 45°) = 35°

Since no two angles of one of the triangles are equal to any two angles of other triangle, the triangles are not similar

Hence,

ΔEFG not ~ ΔQRS

Answer:θ≈2.15

θ≈4.13 are correct

Step-by-step explanation:We can solve this quadratic equation in cos(θ) by using the substitution u = cos(θ):

3u^2 - 2u - 2 = 0

We can use the quadratic formula to solve for u:

u = (-b ± sqrt(b^2 - 4ac)) / 2a

where a = 3, b = -2, and c = -2. Substituting these values, we get:

u = (2 ± sqrt(4 + 24)) / 6

u = (2 ± 2sqrt(7)) / 6

Simplifying this expression, we get:

u = (1 ± sqrt(7)) / 3

Step-by-step explanation:

You want the remainder from division of f(x) = 2x³ +5x² -12x by x -(-1).

The table used for synthetic division is built by listing the zero of the divisor at upper left, and the coefficients of the polynomial across the top to the right of that. They are listed in order of decreasing degree, with any necessary zero coefficients put in the appropriate place(s).

The attachment shows the table and the instructions for filling it out. The value at the bottom in the rightmost column is the remainder from the division.

The remainder theorem tells you that is also the value of the function for x = k.

The remainder from f(x) ÷ (x +1) is 15.

Answer:

  569 square units

Step-by-step explanation:

You want the surface area of the 8-sided shape that has a square "base" 7 units on a side, and a "height" of 20 units.

The slant height of each triangular face is the hypotenuse of a right triangle with legs 7/2 units and 20 units. That height is ...

  h = √(3.5² +20²) = √412.25 ≈ 20.304 units

The area of one triangular face is ...

  A = 1/2bh

  A = 1/2(7)(20.304) . . . one face

There area 8 congruent triangular faces, so the total area is ...

  A = 8(1/2)(7)(20.304) = 8(7)√412.25 ≈ 568.51 ≈ 569

The total surface area is about 569 square units.

The graph is a function: yes.

The domain of this function is: x ≥ -3.

The range of this function: all real numbers.

In Mathematics and Geometry, a range can be defined as the set of all real numbers that connects with the elements of a domain.

Furthermore, the horizontal extent of any graph of a function represents all domain values and they are always read and written from smaller to larger numerical values, and from the left-hand side of the graph to the right-hand side.

By critically observing the graph shown in the image attached above, we can reasonably and logically deduce the following domain and range:

Domain = {-3, ∞}, x ≥ -3, or -3 ≤ x ≤ ∞.

The Perimeter of the given figure rectangle will be 60m. The correct option is 1.

Perimeter refers to the total length of the boundary of a two-dimensional shape or object. It is the distance around the edge of a shape. To find the perimeter of a shape, you add up the lengths of all its sides.

The perimeter of a rectangle is given by the formula:

P = 2(l + w)

where P is the perimeter, l is the length, and w is the width.

Using the values you provided, we can substitute them into the formula:

P = 2(18 + 12) = 2(30) = 60 meters

Therefore, the perimeter of the rectangle with a length of 18 meters and a height of 12 meters is 60 meters.

The number of unicycles, tandem bikes, and tricycles that IRVS Cycle Rental has are:

The relevant equations, ( assuming that unicycles as U, tandem bikes as T, and tricycles as R ) are:

U + T + 32 + R = 57

U + 2T + 2 x 32 + 3R = 115

U = T

Using substitution, we get:

U + 2T + 64 + 3R = 115

U + 2T + 3R = 51

U + 2U + 3R = 51

3U + 3R = 51

Solving gives:

The value of x which I suppose is the angle M is calculated to be 32°

In a right-angled triangle KLM, it is a known fact that the sum of the three angles in any triangle is 180°.

Since angle L is a right angle and has a measure of 90°, we can find angle M by subtracting the sum of angles K and L from 180°.

Thus,

angle M = 180° - angle K - angle L

Answer: 0.15

I don't really know how to show you work on here but you can think about it like this. if 5 x 3 is 15, and if there is a decimal like 0.3 x 0.5 it would result in the answer getting smaller as you're multiplying decimals if that makes sense... so it would result in the answer being 0.15. Sorry if it wasn't a good explanation.

The future value or the total amount due at time t for the loan is $5112.50.

To find the future value or the total amount due at time t for a loan with a principal P, a simple interest rate r, and a period of time t, we can use the formula for calculating simple interest;

A=P + (P × r × t)

where; A = future value or total amount due at time t

P = principal amount

r = simple interest rate

t = time period (in years)

Given the values; P = $5000

r = 4.5% (or 0.045 as a decimal)

t = 6 months (or 0.5 years)

We can substitute these values into the formula and calculate the future value;

A = 5000 + (5000 × 0.045 × 0.5)

A = 5000 + 112.5

A = $5112.50

Let's call the height of the second building "x". We can use trigonometry to solve for x.

First, let's draw a diagram to help visualize the problem:

A        B

\      /

 \    /

  \  / x

   \/

   C

Where:

A is the top of the 200 meters high building

B is the bottom of the second building

C is the point from which the angles of depression and elevation are measured

x is the height of the second building

From the diagram, we can see that:

angle BCA = 20 degrees (angle of depression)

angle BAC = 10 degrees (angle of elevation)

AB = 200 meters

Using the tangent function, we can write:

tan(20) = x / AB (tangent of angle BCA)

tan(10) = x / (AB + x) (tangent of angle BAC)

We can solve these equations for x:

x = AB * tan(20) (multiply both sides by AB)

x = (AB * tan(10)) / (1 - tan(10)) (multiply both sides by 1 - tan(10), then simplify)

Plugging in the values we know:

x = 200 * tan(20)

x = (200 * tan(10)) / (1 - tan(10))

Using a calculator:

x ≈ 67.35 meters

Therefore, the height of the second building is approximately 67 meters (to the nearest hundred meters).

The expressions that are equivalent to the expression 8x + 32y are:

4(4 ⁢x + 8y) − 2⁢(4x)

8(x + 4y)

Equivalent expressions are expressions that work the same even though they look different.

If two algebraic expressions are equivalent, then the two expressions have the same value when we substitute the same value(s) for the variable(s).

Let's simply the options to see if they are equivalent to the expression 8x + 32y:

4(4 ⁢x + 8y) − 2⁢(4x)   = 16x + 32y - 8x

                               = 8x + 32y

8(x + 4y)  = 8x  + 32y

(2x + 12y) + (6x + 18y) = 2x + 6x + 12y + 18y

                                   = 8x + 30y

Therefore, only 4(4 ⁢x + 8y) − 2⁢(4x) and 8(x + 4y)  are equivalent to the expression below.

Here, we have,

let X and Y be the two dimensions.

Area will be X times Y.

XY = 3000000

Y = 3000000 / X

Perimeter = 2x + 3y

substituting the values:

Perimeter = 2x + 3*3000000 / x

         = 2x + 9000000 / x

so, we get,

2 = 9000000 / x^2

x^2 = 9000000 / 2 = 4500000

x = sqrt(4,500,000)

y = 3000000 / 2121.32
