how many sides does a rhombicosidodecahedron have

Answer:

C. k = -3

Step-by-step explanation:

First of all please try and understand math, cheating will never get you anywhere :)

So we can deduce that the value k is -3 for the following reasons:

If k is greater than 1, it will become narrower

If k is negative, it will shift right

Therefore we can conclude that k = -3

(I might be wrong but we will see)

The function g(x) transformed to f(x) by 3 unit on right side.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

We have the graph

g(x) = f(k x)

Here k represent the transformation or we can say shifting.

If  k is greater than 1 then the graph will become narrower

and, if  k is negative or less than then it will shift right.

From the graph the function g(x) is shifted to f(x) by 3 units.

Thus, the value of k is -3 ( Right side shifting)

Step-by-step explanation:

Under a reflection in the line y = - x

a point (x, y ) → (- y, - x ), thus

S(- 2, - 10 ) → (10, 2 )

T(- 2, - 3 ) → T'(3, 2 )

U(3, - 3 ) → U'(3, - 3 )

V(3, - 10 ) → V'(10, - 3 )

The first thing is to define each one:

Polynomial: expression made with constants, variables and exponents, which are combined using addition, subtraction and multiplication. Exponents can only be natural numbers and the polynomial cannot have an infinite number of terms.

Example:

This is a:  [tex]5x^{3} + 4x^{2} -99x +20[/tex]

Degree: It is the exponent with the highest degree. If a monomial of those that are forming the polynomial has two unknowns, each with its exponent, these add up since we would be doing a multiplication of monomials.

Example: [tex]5x^{3} + 4x^{2} -99x +20[/tex]

The degree of this polynomial is 3 because it is the largest exponent.

Linear term coefficient: is the number that multiplies the variable with the highest exponent

Example: [tex]5x^{3} + 4x^{2} -99x +20[/tex]

In this case it is 5 because [tex]x^{3}[/tex] is the variable with the highest exponent

Constant term coefficient: is one that is found in a polynomial alone, that is, without multiplying the x or another unknown.

Example:  [tex]5x^{3} + 4x^{2} -99x +20[/tex]

In this case it is 20 because it is the one found without multiplying any linear term (x)

Answer:

Exponential

Step-by-step explanation:

So let’s start off by looking at how much x is growing by each time

X is growing by 8 each time

Next look at how much y is growing by

-6 to -24 is a difference of 18

-24 to -96 is a difference of 72

And lastly -96 to -384 is a difference of 288

So we can now say that it is not linear because a linear equation grows by a constant number (like adding)

To determine if it is exponential see if it is growing by a constant multiplier

24 divided by 6 is 4

96 divided by 24 is 4

384 divided by 96 is 4

It is exponentially growing by 4

Answer:

D. square root of 2

Step-by-step explanation:

The square root of 2 is an irrational number because it cannot be written as a ratio of two integers.

Final answer:

Choice D, square root 2, is an example of an irrational number. Unlike the other options, it cannot be expressed as a fraction with an integer numerator and denominator.

Explanation:

An irrational number is a number that cannot be expressed as a simple fraction, meaning its decimal form is non-terminating and non-repeating. Among the options given, choice D, which is square root 2 (written as √2), is an example of an irrational number. Option A is 74/99, a fraction that simplifies to a rational number; option C is 3/4, also a rational number; and the option B is missing from the context provided.

To determine between which two consecutive integers an irrational number like √2 lies, we first identify the perfect squares nearest to the number we are taking the square root of. For √2, the perfect squares are 1 (√1) and 4 (√4), which correspond to the integers 1 and 2. √2 lies between these two integers because 2 is greater than 1 and less than 4, and since the square root function is increasing, √2 is more than 1 and less than 2.

Answer: The radius of the circle is 7.75 m (approximately)

Step-by-step explanation: The area of a sector is determined as follows;

Area of sector = (∅/360) x πr²

The area has been given as 10π, and the angle subtended by the sector has been given as 60. Substituting for known values we now have;

10π = (60/360) x πr²

10π = (1/6) x πr²

By cross multiplication we now have;

(10π/π) x 6 = r²

10 x 6 = r²

60 = r²

Add the square root sign to both sides of the equation

√60 = √r²

7.7459 = r

The radius of the circle is approximately 7.75 meters

Answer:

Horizontal shift to the right

Vertical compression

Reflection across the x axis

Vertical shift up

Step-by-step explanation:

Given that the parent function was [tex]g(x)=x^2[/tex]

we notice the following transformations:

a) a horizontal shift to the right in 1 (one) unit rendering: [tex]g(x)=(x-1)^2[/tex]

b) a vertical compression by multiplying our function by a number smaller than 1 ( [tex]\frac{1}{5}[/tex] ), rendering: [tex]g(x)=\frac{1}{5} (x-1)^2[/tex]

c) a reflection across the x-axis by flipping the sign of the function and rendering: [tex]g(x)=-\frac{1}{5} (x-1)^2[/tex]

d) a vertical shift of 7 units up thus giving finally: [tex]g(x)=-\frac{1}{5} (x-1)^2+7[/tex]

The parent function f(x) = x² has undergone a reflection across the x-axis, a vertical compression, a horizontal shift right, and a vertical shift up to transform into g(x) = -1/5(x - 1)² + 7.

The student asked about the transformations that turned the parent function f(x) = x² into g(x) = -1/5(x - 1)² + 7. Examining the function g(x), we can identify several transformations:

Answer: C. 10 cm

Step-by-step explanation:

the hypotenuse of a right triangle will always be longer than the other 2 sides.  So 10 cm

To solve this you must use Pythagorean theorem:

[tex]a^{2} +b^{2} =c^{2}[/tex]

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 8 cm

b = 6 cm

c = x

^^^Plug these numbers into the theorem

[tex]8^{2} +6^{2} =x^{2}[/tex]

simplify

64 + 36 = [tex]x^{2}[/tex]

100 = [tex]x^{2}[/tex]

To remove the square from x take the square root of both sides to get you...

Step-by-step explanation:

Yes, this is in standard form

The experimental probability of spinning a green is 5/10 or 0.5, which means there's a 50% chance of landing on green based on Samantha's 10 trials.

The question is about determining the experimental probability of spinning a green on a spinner used in an experiment. Experimental probability is calculated as the ratio of the number of times an event occurs to the total number of trials. In Samantha's case, she spun the spinner 10 times and landed on green 5 times. Thus, the experimental probability of spinning a green is calculated as follows:

Number of times green was spun: 5

Total number of spins (trials): 10

Experimental Probability of green: 5/10 or 0.5 (50%)

Experimental probability differs from theoretical probability as it is based on actual results from an experiment, rather than calculated from a theoretical perspective without actual trials.

The experimental probability of spinning green is 0.5 or 50%, calculated by dividing the number of green outcomes (5) by the total number of trials (10).

The student is asking about the experimental probability of spinning a green on a spinner after conducting an experiment for 10 trials. The results of the experiment were Blue-0, Red-1, Yellow-4, and Green-5. To find the experimental probability, we need to divide the number of times green occurred (favorable outcomes) by the total number of spins (total trials).

The experimental probability of spinning a green is calculated as follows:

Number of favorable outcomes (spinning green) = 5

Total number of trials = 10

Experimental probability of green = Number of favorable outcomes / Total number of trials

Experimental probability of green = 5 / 10 = 0.5 or 50%

Therefore, the experimental probability of spinning a green is 0.5 or 50%.

Answer:

Given that the area where apple is grown: 25 acres

Total area of cultivation:40 acres

Percentage ={ (Area where apple is grown / Total area of cultivation) ×100

=>(25/40)×100

=>(25/4)×10

=>62.5%

∴The percentage of the trees are within the orchard area is : 62.5%

MARK AS BRAINLIEST

The theoretical probability of selecting a tree within the acres of apple trees is 62.5%.

To find the probability of selecting a tree within the acres of apple trees, we need to consider the proportion of apple trees to the total number of trees in the orchard.

The total area of the orchard is 40 acres, and the area dedicated to apple trees is 25 acres. Since the trees are equally distributed within the orchard, the proportion of apple trees to the total number of trees is:

[tex]\[ \text{Proportion of apple trees} = \frac{\text{Area of apple trees}}{\text{Total area of orchard}} \][/tex]

[tex]\[ \text{Proportion of apple trees} = \frac{25}{40} = 0.625 \][/tex]

To convert this proportion to a percentage, we multiply by 100:

[tex]\[ \text{Probability} = 0.625 \times 100\% = 62.5\% \][/tex]

Rounded to the nearest tenth of a percent, the theoretical probability of selecting a tree within the acres of apple trees is 62.5%. Therefore, the correct answer is: 62.5%
