Find the area of this figure. Use 3.14 for pi. Wrote your answer as a decimal.

Answer:

Option-C=> 62.5%

Step-by-step explanation:

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%

R represents the radius of the lawn

r represents the area of the circular bed

So,

Area of the remaining lawn, A = area of the lawn - area of the circular flower bed

A = πR^2 - π^2

A = π(R^2 - r^2)

A = π(10^2 - 5^2)

The average rate of change of the function g(x) = x^2 + 10x + 23 over the interval -8 < x < -4 is -0.5.

To determine the average rate of change for the function g(x) = x^2 + 10x + 23 over the interval -8 < x < -4, we first plug these x-values into the function to find the corresponding y-values:

G(-8) = (-8)^2+ 10*(-8) + 23 = 9

G(-4) = (-4)^2+ 10*(-4) + 23 = 7.

The average rate of change will then be the change in y-values divided by the change in x-values, so:

Average Rate of Change = [G(-4) - G(-8)]/[-4 - (-8)] = (7 - 9)/(-4 - (-8)) = -2/4 = -0.5.

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: Option C

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%.

Final answer:

To find the equivalent equation for the monthly growth of the wildflowers, we need to convert the yearly growth rate to a monthly growth rate. The monthly growth rate is the 12th root of the yearly growth rate. The equivalent equation is Y=1000((1.08)^(1/12))^mx.

Explanation:

To find an equivalent equation that represents the monthly growth of the wildflowers, we need to convert the yearly growth rate into a monthly growth rate. Since there are 12 months in a year, the monthly growth rate is the 12th root of the yearly growth rate.

Given the equation Y = 1000(1.08)^x, where x represents the number of years, the equivalent equation for the monthly growth rate is Y = 1000((1.08)^(1/12))^mx.

Here, a = 12, b = 1/12, c = 1.08, and d = m.

The value we get are :

a = 1000

b = 1.00692

c = 0

d = 0

The given equation, Y=1000(1.08)^x, represents the yearly growth of wildflowers, where:

Y is the number of wildflowers in year x.

1000 is the initial number of wildflowers (at year x=0).

1.08 represents the yearly growth factor (8% increase).

x is the year number.

To find the equivalent equation for monthly growth, we need to consider that there are 12 months in a year. This means the yearly growth factor can be further divided into monthly growth factors.

Divide the exponent by the number of months:

In the yearly equation, the exponent x represents the year number. To represent months, we need to divide x by 12 (number of months in a year).

The new equation becomes: Y = 1000 * (1.08)^(x/12).

Apply the power of a power property:

(a^b)^c = a^(b*c). In this case, a = 1.08, b = 1/12, and c = x.

The equation becomes: Y = 1000 * ((1.08)^(1/12))^x.

Simplify the equation:

Calculate (1.08)^(1/12) using a calculator. This value is approximately 1.00692 (rounded to nearest thousandth).

Substitute this value back into the equation: Y = 1000 * (1.00692)^x.

Therefore, the equivalent equation representing the monthly growth of wildflowers is:

Y = 1000 * (1.00692)^x

Values of a, b, c, and d:

a = 1000 (initial number of wildflowers)

b = 1.00692 (monthly growth factor)

c = 0 (no x term in the exponent)

d = 0 (no constant term)

Question:

Some studies find that the yearly growth rate of a certain wildflower can be modeled by the equation Y=1000(1.08)^x. Use the properties of exponents to show an equivalent equation that represents the monthly growth of the wildflowers. Find the values of a, b, c, and d. Round to the nearest thousandth as needed.

-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

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)

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.

Answer: The flagpole is 75.6 feet (approximately)

Step-by-step explanation: Please refer to the picture attached.

The man is at point C and the base of the building is point B, and he looks up at an angle of elevation of 60 degrees to the bottom of the flagpole. Note that the flagpole is attached to the top of the edge of the building which is point A. Also he looks up at an angle of elevation of 62.5 degrees to the top of the flagpole which is point A.

If his distance from the base of the building is 400 feet (line BC), then we would start by calculating the height of the building plus the flagpole (line FB) and then the height of the building itself (line AB) and the difference between both would be the height of the flagpole (line FA).

We shall use the trigonometric ratios as follows;

In triangle FBC,

Tan C = opposite/adjacent

Tan 62.5 = FB/400

Tan 62.5 x 400 = FB

1.9209 x 400 = FB

768.36 = FB

Also in triangle ABC,

Tan C = opposite/adjacent

Tan 60 = AB/400

Tan 60 x 400 = AB

1.732 x 400 = AB

692.8 = AB

The height of the vertical flagpole can be derived as

FA = FB - AB

FA = 768.36 - 692.8

FA = 75.56

FA ≈ 75.6

Therefore the height of the flagpole is 75.6 feet (approximately)

The height of the flagpole is required to be found with the given angles of elevation.

The height of the flagpole is 75.6 feet.

From trigonometric ratios

[tex]\tan60=\dfrac{BD}{BC}\\\Rightarrow BD=BC\tan60\\\Rightarrow BD=400\tan60[/tex]

[tex]\tan62.5=\dfrac{AB}{BC}\\\Rightarrow AB=BC\tan62.5\\\Rightarrow AB=400\tan62.5[/tex]

So,

[tex]AD=AB-BD\\\Rightarrow AD=400(\tan62.5-\tan60)\\\Rightarrow AD=75.6\ \text{feet}[/tex]
