After answering the prοvided questiοn, we can cοnclude that  Tο circle cοmplete the cοpied triangle, draw a pοlygοn thrοugh pοints D, E, and F.

A circle appears tο be a twο-dimensiοnal cοmpοnent that is defined as the cοllectiοn οf all pοints in a jet that are equidistant frοm the hub. A circle is typically depicted with a capital "O" fοr the centre and a lοwer sectiοn "r" fοr the radius, which is the distance frοm the οrigin tο any pοint οn the circle.

The fοrmula 2r gives the girth (the distance frοm the centre οf the circle), where (pi) is a prοpοrtiοnality cοnstant rοughly equal tο 3.14159. The fοrmula r² cοmputes the circumference οf a circle, which refers tο the amοunt οf space inside the circle.

Fοllοw these steps tο duplicate the οriginal triangle using οnly twο οf its sides and the included angle:

Find the pοint where the ray and the circle intersect. Place the tip οf the cοmpass at pοint E and draw an arc that intersects the circle twice. Label the pοint that is οn the same side οf side AC as pοint B as pοint F.

Answer:

[tex]\boxed{\frac{8}{13} }[/tex]

Step-by-step explanation:

Probability is found by dividing the number of favorable outcomes by the total number of outcomes.

[tex]\text{P}=\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]

For this problem, the favorable outcome is selecting a blue or green marble. There are 8 outcomes for this because there are 6 outcomes for blue and 2 fr green.

The total outcomes are all the marbles. Each marble could be an outcome, so there are 13 outcomes (1 for each marble).

[tex]\text{P}=(\text{blue or green})=\dfrac{8}{13}[/tex]

This fraction cannot be reduced, so the probability of selecting a blue or green marble is 8/13.

The rate of change of the angle of elevation from the lamp to the javelin when the javelin is 37 feet off the ground is zero.

Let's denote the distance from the lamp to the point directly below the javelin by x, and the height of the javelin above the ground by y. Then we have two right triangles: one with legs x and y, and hypotenuse 31, and another with legs x and 37-y, and hypotenuse 37. Using the Pythagorean theorem, we can write:

x^2 + y^2 = 31^2

x^2 + (37-y)^2 = 37^2

Taking the derivative with respect to time t of both sides of each equation, we get:

2x(dx/dt) + 2y(dy/dt) = 0

2x(dx/dt) - 2(37-y)(dy/dt) = 0

Solving for (dy/dt) in terms of (dx/dt), we get:

(dy/dt) = x(dy/dx)/(-y+37)

At the given moment when the javelin is 37 feet off the ground, we have y = 37, and so:

(dy/dt) = x(dy/dx)/(-y+37) = x(dy/dx)/(-37+37) = 0

This means that the rate of change of the angle of elevation is zero at this moment. In other words, the angle of elevation is not changing at the moment when the javelin is 37 feet off the ground.

Step-by-step explanation:

According to the question we can conclude that expanding the garden will increase its area by 48 square feet.

Let's call the base of the original right triangle "b" and the height "h". The area of the right triangle is given by the formula:

Area = (1/2) * base * height

So we have:

16 = (1/2) * b * h

When we factor in a single of the variables, then obtain:

b * h = 32

Now, the new triangle will have twice the base and twice the height of the original triangle, so the new base will be 2b and the new height will be 2h. The area of the new triangle is given by the formula:

(Half) * Additional Base * Increased Height = New Area

Plugging in the new values, we get:

New area = (1/2) * 2b * 2h

Simplifying:

New area = 2bh

Now we need to find by how much the area has increased, which is the difference between the new area and the old area:

Area increase = Current area minus Old area.

Area increase = 2bh - 16

Substituting bh = 32, we get:

Area increase = 2(32) - 16

Area increase = 48

Therefore, expanding the garden will increase its area by 48 square feet.

The conclusion that is best supported by the box plots on the trampoline parts owned by Bounce Zone and Jump World is B. For both companies, about 25% of the parks have 21 or fewer trampolines.

The box plot shows that both Bounce Zone and Jump World have 21 or fewer trampolines in about 25 % of their parks.

We know this because both Bounce Zone and Jump World have box plots where the box starts from 21 trampolines. The beginning of a box in a box plot represents the 25% mark or the first quartile so everything that falls below it is less than 25%.

Answer: like three out of a thousand, would be likely to last less than 525 hours or more than 975 hours.

Step-by-step explanation:

normal distribution is shaped like a bell curve with the average (mean) at the center.

A light bulb in your problem is most likely to last about 750 hours. One standard deviation up from that would be 750 + 75, which is 825 hours, and one standard deviation down is 750 - 75, which is 675 hours.

According to the empirical rule, the interval from the average to +1 standard deviation (750 to 825) and the interval from the average to -1 standard deviation (675 to 725) each have a 34.1% probability.

From +1 to +2 standard deviations and -1 to -2 standard deviations (825 to 900 and 600 to 675) the probability is 13.5% for each interval.

From +2 to +3 standard deviations and -2 to -3 standard deviations (900 to 975 and 525 to 600) the probability is 2.1% for each interval.

These percentages are the same for any normal distribution problem. If you add up the chances you can find the probability a light bulb will last an increasing range of times centered around the average:

Within one standard deviation of the average: 68.3% (chance it will last 675 to 825 hours)

Within two standard deviations of the average: 95.4% (chance it will last 600 to 900 hours)

Within three standard deviations of the average: 99.7% (chance it will last 525 to 975 hours)

And only a very few, like three out of a thousand, would be likely to last less than 525 hours or more than 975 hours.

Step-by-step explanation:

To find the measure of arc BC, first calculate the measures of arc ABC and arc BCD.

Definitions:

The measure of an inscribed angle is half the measure of the intercepted arc.

Therefore, we can use the inscribed angle theorem to calculate the measures of arcs ABC and BCD:

[tex]\boxed{\begin{aligned}\angle ADC&=\dfrac{1}{2} \overset{\frown}{ABC}\\\\\implies 70^{\circ}&=\dfrac{1}{2} \overset{\frown}{ABC}\\\\ \implies \overset{\frown}{ABC}&=140^{\circ}\end{aligned}}[/tex]       [tex]\boxed{ \begin{aligned}\angle BAD&=\dfrac{1}{2} \overset{\frown}{BCD}\\\\\implies 98^{\circ}&=\dfrac{1}{2} \overset{\frown}{BCD}\\\\ \implies \overset{\frown}{BCD}&=196^{\circ}\end{aligned}}[/tex]

The sum of the arcs is 360°. Therefore:

[tex]\overset{\frown}{ABC}+\overset{\frown}{CD}+\overset{\frown}{AD}=360^{\circ}[/tex]

Substitute the given measure of arc AD and the found measure of arc ABC and solve for arc CD:

[tex]\implies 140^{\circ}+\overset{\frown}{CD}+80^{\circ}=360^{\circ}[/tex]

[tex]\implies \overset{\frown}{CD}=140^{\circ}[/tex]

The measure of arc BCD is the sum of arcs BC and CD. Therefore:

[tex]\overset{\frown}{BC}+\overset{\frown}{CD}=\overset{\frown}{BCD}[/tex]

To find the measure of arc BC, substitute the found measures of arc CD and arc BCD and solve for BC:

[tex]\implies \overset{\frown}{BC}+140^{\circ}=196^{\circ}[/tex]

[tex]\implies \overset{\frown}{BC}=56^{\circ}[/tex]

Therefore, the measure of arc BC is 56°.

Answer:

2cos(3ẞ/2)(sin(7ẞ/2) + cos(19ẞ/2))

Step-by-step explanation:

We can use the identity for the sum of two sines to rewrite the expression as follows

sin 4ẞ + sin 10ẞ = 2sin(7ẞ/2)cos(3ẞ/2)

Similarly, we can use the identity for the sum of two cosines to rewrite the expression as follows

22ẞ + sin 16ẞ = 2cos(19ẞ/2)cos(3ẞ/2)

Therefore, we have

sin 4ẞ + sin 10ẞ + 22ẞ + sin 16ẞ = 2sin(7ẞ/2)cos(3ẞ/2) + 2cos(19ẞ/2)cos(3ẞ/2)

Factoring out the common factor of cos(3ẞ/2), we get

sin 4ẞ + sin 10ẞ + 22ẞ + sin 16ẞ = 2cos(3ẞ/2)(sin(7ẞ/2) + cos(19ẞ/2))

Therefore, the expression can be expressed as a product of 2cos(3ẞ/2) and the sum of sin(7ẞ/2) and cos(19ẞ/2).

B. The graphed line will eventually level off because the ecosystem

lacks a way to recycle matter.

Step-by-step explanation:

Based on the information I can get from the question, option B is likely the correct answer. The graphed line will eventually level off because there is no way for dead organisms to be recycled back into the ecosystem and no additional nutrients being added. This means that the bacteria will consume all available resources and will not be able to sustain further growth, resulting in the population reaching its carrying capacity. Option A is not relevant to the growth of the bacteria population, and option D is incorrect as there are no additional nutrients being added, indicating that a new carrying capacity is not expected. Therefore, option B is the correct choice.

Therefore, the balance after 3 years of continuous compounding at an annual interest rate of 3.1% is approximately $2,701.85.

Percent is a way of expressing a number as a fraction of 100. The word "percent" means "per hundred," so when we say something is, for example, 25%, we mean it is 25 out of 100, or 0.25 as a decimal. Percentages are often used to express ratios or proportions, such as in statistics, finance, and everyday life. Some common examples include: Interest rates: A bank might advertise a 5% annual interest rate on a savings account, which means that the account balance will increase by 5% (or 0.05) each year. Discounts: A store might offer a 20% discount on a product, which means that the price will be reduced by 20% (or 0.20) of the original price. Grades: A student might receive a grade of 85% on a test, which means that they answered 85 out of 100 questions correctly. Percentages can be converted to decimals or fractions, and vice versa, using simple arithmetic operations. For example, to convert a percentage to a decimal, divide by 100. To convert a decimal to a percentage, multiply by 100 and add a percent sign (%).

Here,

The formula for continuous compounding is:

[tex]A = Pe^{rt}[/tex]

where A is the ending balance, P is the principal amount, r is the annual interest rate (as a decimal), t is the time in years, and e is the mathematical constant approximately equal to 2.71828.

Answer:

x = 40

Step-by-step explanation:

given a line DE parallel to a side AC of the triangle and intersecting the other two sides, it intersects those sides proportionally , that is

[tex]\frac{CE}{BE}[/tex] = [tex]\frac{AD}{BD}[/tex] ( substitute values )

[tex]\frac{25}{x-25}[/tex] = [tex]\frac{15}{24-15}[/tex]

[tex]\frac{25}{x-25}[/tex] = [tex]\frac{15}{9}[/tex] ( cross- multiply )

15(x - 25) = 9 × 25 = 225 ( divide both sides by 15 )

x - 25 = 15 ( add 25 to both sides )

x = 40

Hence, the rectangular prism's vοlume is 3 cubic meters. A square base and a 1/5 m height define a rectangular prism.

A prism is a three-dimensiοnal sοlid οbject in geοmetry that is cοnnected by a series οf parallelοgrams frοm twο identical parallel pοlygοnal bases. The prism might have a rectangular, triangular, οr hexagοnal shape depending οn the geοmetry οf the pοlygοnal bases. The fοrm οf a prism's base gives rise tο its name. Fοr instance, the base οf a triangular prism is a triangle, as οppοsed tο the base οf a rectangular prism. Parallelοgrams make up the prism's οther faces.

given

The rectangular prism's square base has a surface area οf 7 1/2 m². With this knοwledge, we can determine hοw lοng οne side οf the square base is:

square area =side²

7 1/2 = side²

The mixed number can be changed intο an incοrrect fractiοn as fοllοws:

7 1/2 = 15/2

15/2 = side²

side = √(15/2) = √15/√2 = (√15/2)√2 = (√30)/2

The rectangular prism's height is specified as 1/5 m.

Hence, the rectangular prism's vοlume is:

Vοlume equals (base area) times height.

Height + (side²) = vοlume

Vοlume is equal tο [((30/2)2] (1/5)

Vοlume = (1/5) (30/4)

Size = 6/2

Amοunt = 3 m³

Hence, the rectangular prism's vοlume is 3 cubic meters. A square base and a 1/5 m height define a rectangular prism.

Answer:

  4 minutes

Step-by-step explanation:

You want to know how long it takes to drain a cylindrical tank 1.8 ft in diameter and 3 ft long at the rate of 1.7 ft³/minute. (π = 3.14)

The volume of a cylinder can be found using the formula ...

  V = (π/4)d²h . . . . . . . diameter d, height h

Then the volume of the oil tank is ...

  V = 3.14/4(1.8 ft)²(3 fft) = 7.6302 ft³

The time it takes to empty the tank is found by dividing the volume by the rate:

  (7.6302 ft³)/(1.7 ft³/min) ≈ 4.49 min ≈ 4 min

It will take about 4 minutes to empty the tank.
