The exact value of the volume of the sphere is V = 20.833π cm³ and the exact value is V = 64.45 cm³

A sphere is defined as symmetrical and round in shape. It is also referred to as a three dimensional solid, that has all its surface points at equal distances from the center.

The formula for the volume of a sphere is:

V = ⁴/₃πr³

where:

V = volume

r = radius

The radius of a sphere is half its diameter.

We are given diameter = 5cm

Thus: r = 5/2 = 2.5 cm

V = ⁴/₃π * 2.5³

V = 20.833π cm³

What is Law of sines ?

The Law of Sines is a trigonometric formula that relates the side lengths of a triangle to the sine of its angles. It states that in any triangle ABC:

a / sin(A) = b / sin(B) = c / sin(C)

where a, b, and c are the side lengths of the triangle, and A, B, and C are the opposite angles.

This formula can be used to solve for the unknown sides or angles of a triangle when given enough information about the other sides and angles. The Law of Sines is especially useful when dealing with triangles that are not right triangles, or when only a few side lengths and angles are known.

According to the question:

We can solve this problem by using the Law of Sines and the fact that the sum of the angles in a triangle is 180 degrees.

First, we can find the measure of angle A in triangle ABC:

A = 180 - 48 - 48 = 84 degrees

Next, we can use the Law of Sines to find the length of side AC:

sin(84) / 50 = sin(48) / AC

AC = sin(84) * 50 / sin(48) ≈ 64.4

Now, we can use the fact that the sum of the angles in triangle AQS is 180 degrees to find the measure of angle QAS:

QAS = 180 - 20 - 90 = 70 degrees

Finally, we can use the Law of Sines again to find the length of RS:

sin(70) / RS = sin(48) / AC

RS = sin(70) * AC / sin(48) ≈ 72.6

Therefore, the length of RS is approximately 73 meters (to the nearest meter).

The length of line segment AC is equal to 34 units.

In Mathematics and Geometry, the Tangent Secant Theorem states that if a secant segment and a tangent segment are drawn to an external point outside a circle, then, the product of the length of the external segment and the secant segment's length would be equal to the square of the tangent segment's length.

By applying the Tangent Secant Theorem to this circle, we have the following:

DC² = AB × BC

15² = (3x + 1) × 9

225 = 27x + 9

27x = 225 - 9

27x = 216

x = 216/27

x = 8

Now, we can determine the length of AC;

AC = AB + BC

Answer:

can you like write it out normally please, i can answer it then

Step-by-step explanation:

The odds of answering at least 9 questions correctly out of 15 by choosing at random is approximately 0.120

To solve this problem, we can use the binomial distribution, which models the probability of getting a certain number of successes in a fixed number of independent trials, each with the same probability of success.

In this case, we have 15 independent trials (the 15 questions) and the probability of success in each trial is 1/4 (the probability of guessing the correct answer among 4 choices). We want to find the probability of getting at least 9 successes.

Using a binomial distribution calculator, we can calculate this probability as

P(X ≥ 9) = 1 - P(X < 9) = 1 - binomcdf(15, 1/4, 8) ≈ 0.120

where binomcdf is the cumulative distribution function of the binomial distribution, which gives the probability of getting up to a certain number of successes (in this case, up to 8). The complement of this probability (1 minus the probability of getting up to 8 successes) gives the probability of getting at least 9 successes.

The function to represent the bacteria population after t hours is f(t) = 7400 * [tex]e^(0.13/60 * t)[/tex].

A derivative is a measure of how much a function changes as its input value changes. It is defined as the limit of the rate of change of the function with respect to its input as the change in the input approaches zero.

The function to represent the bacteria population after t hours, where the function's constant can be used to calculate the rate of change per minute is:

f(t) = 7400 * [tex]e^(0.13/60 * t)[/tex]

where:

f(t) = population of bacteria after t hours

e = Euler's number (approximately 2.71828)

t = time in hours

0.13/60 = rate of change per minute (converted from 13% per hour)

To determine the percentage rate of change per minute, we can calculate the derivative of the function with respect to time (t):

df/dt = 7400 * 0.13/60 * [tex]e^(0.13/60 * t)[/tex]

At t = 0 (the start of the experiment), the rate of change per minute is:

df/dt = 7400 * 0.13/60 * [tex]e^(0.13/60 * 0)[/tex] = 12.1166

To express this rate of change as a percentage, we can divide it by the initial population and multiply by 100:

rate of change per minute = (df/dt) / P(0) * 100% = 12.1166 / 7400 * 100% = 0.1638% (rounded to the nearest hundredth of a percent)

Answer:

n=6 sides

Step-by-step explanation:

We know that the sum of Interior angles of Polygon = 180(n-2)

Sum of Exterior angles of Polygon = 360

so 180(n-2)=2x360

Therefore, by solving we get n=6 sides.

The number of sides of a regular polygon is 6 sides.

The formula for calculating the sum of interior angles is (n-2)×180° where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.

Given that, the sum of the measures of its interior angles is twice the sum of the measures of its exterior angles.

We know that, the sum of the measures of its exterior angles is 360°.

Now, the sum of the measures of its interior angles

= 2×360°

Suav would have run approximately [tex]$970$[/tex] miles in [tex]$25$[/tex] weeks, to the nearest whole number.

What are the whole numbers?

Whole numbers are the set of numbers that include all positive integers (1, 2, 3, ...) as well as zero (0). Whole numbers do not include any negative numbers or fractions. Therefore, the set of whole numbers is {0, 1, 2, 3, ...}.

Suav runs [tex]$20$[/tex] miles the first week. Let's use a formula to calculate the number of miles he runs in subsequent weeks. Let [tex]$m$[/tex] be the number of miles he runs in a particular week, and [tex]$w$[/tex] be the number of weeks elapsed since the first week. Then, we have:

[tex]$$m = 20 \cdot 1.05^{w-1}$$[/tex]

This formula takes into account the [tex]$5%$[/tex] increase in miles each week, starting from the initial [tex]$20$[/tex] miles in the first week.

To find the total number of miles Suav runs over [tex]$25$[/tex] weeks, we can sum up the miles he runs in each week using the formula above. That is,

[tex]$$\text{Total miles} = 20 + m_2 + m_3 + \cdots + m_{25}$$[/tex]

where [tex]$m_2, m_3, \ldots, m_{25}$[/tex] are the number of miles he runs in the second to [tex]25$th[/tex] week, respectively.

We can use the formula for [tex]$m$[/tex] to find each of these values. For example, the number of miles he runs in the second week is:

[tex]$$m_2 = 20 \cdot 1.05^{2-1} = 21$$[/tex]

Similarly, we can find the number of miles he runs in each of the other weeks:

[tex]m_3 &= 20 \cdot 1.05^{3-1} = 22.05[/tex]

[tex]m_4 &= 20 \cdot 1.05^{4-1} = 23.103[/tex]

[tex]&\vdots[/tex]

[tex]m_{25} &= 20 \cdot 1.05^{25-1} = 57.597[/tex]

Now, we can substitute these values into the formula for the total miles and simplify:

[tex]\text{Total miles} &= 20 + 21 + 22.05 + \cdots + 57.597 \&\approx 970[/tex]

Therefore, Suav would have run approximately [tex]$970$[/tex] miles in [tex]$25$[/tex] weeks, to the nearest whole number.

Apples make up one-third of the dozen fruits in a fruit vendor cart. If bananas make up the remaining fruit and oranges make up 1/4 of the total fruit, there are 2.5 dozen bananas in the fruit vendor's cart.

First, let's calculate how many apples are in the cart:

1/3 of 6 dozen fruits = 2 dozen fruits are apples

Next, let's calculate what proportion of the fruits are oranges:

1/4 of all fruits = (1/4) x 6 dozen = 1.5 dozen fruits are oranges

To find the number of dozen bananas, we can subtract the number of dozen apples and oranges from the total number of dozen fruits in the cart:

Total number of dozen fruits = 6 dozen

Number of dozen apples = 2 dozen

Number of dozen oranges = 1.5 dozen

Number of dozen bananas = 6 dozen - 2 dozen - 1.5 dozen

Number of dozen bananas = 2.5 dozen

Therefore, there are 2.5 dozen bananas in the fruit seller's cart.

Entertainment will comprise 90% of Ryan's total budget. The amount budgeted towards entertainment each month will be 90% of his take-home pay.

The number of periods or cycles per second is called frequency. The SI unit for frequency is the hertz (Hz). One hertz is the same as one cycle per second.

Let's assume Ryan's take-home pay is P dollars.

Given that Ryan saves 10% of his take-home pay for retirement, he will save 0.10P dollars.

The remainder of his take-home pay after saving for retirement will be 90% of his take-home pay, which is 0.90P dollars.

Now, if Ryan allocates the remainder of his take-home pay to entertainment, the percentage of his total budget that entertainment will comprise can be calculated as:

Percentage of entertainment budget = (Entertainment budget / Total budget) * 100

Since the entertainment budget is 0.90P dollars and the total budget is P dollars, the percentage of his total budget that entertainment will comprise is:

Percentage of entertainment budget = (0.90P / P) * 100

Percentage of entertainment budget = 90%

So, entertainment will comprise 90% of Ryan's total budget.

The amount of money budgeted towards entertainment each month will be 0.90P dollars, which is 90% of his take-home pay.

Therefore, Entertainment will comprise 90% of Ryan's total budget. The amount budgeted towards entertainment each month will be 90% of his take-home pay.

To find the perimeter of a rectangle, we need to add up the lengths of all its sides.

First, gather the coordinates:

R - (4, 5)

U - (8, -3)

F - (-6, 0)

O - (-2, -8)

Using the coordinates given, we can calculate the lengths of the sides of the rectangle using the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

So, for the rectangle with vertices R, U, F, and O, we have:

Side RU: d = √((8 - 4)^2 + (-3 - 5)^2) = √(16 + 64) = √80

Side UF: d = √((-6 - 8)^2 + (0 - (-3))^2) = √(196 + 9) = √205

Side FO: d = √((-6 - (-2))^2 + (0 - (-8))^2) = √(16 + 64) = √80

Side OR: d = √((-2 - 4)^2 + (-8 - 5)^2) = √(36 + 169) = √205

Since opposite sides of a rectangle are congruent, we have RU = FO and UF = OR. Therefore, the perimeter of the rectangle is:

Perimeter = RU + UF + FO + OR

Perimeter = √80 + √205 + √80 + √205

Perimeter ≈ 38.57

Therefore, the perimeter of the rectangle is approximately 38.57 units.

Using Trigonometric functions, the height of the tree is approximately 50.6 feet.

Let's call the height of the tree "h" and the distance between the forester's original position and the base of the tree "x". Then, when the forester moves 20 feet closer to the tree, the distance between the new position and the base of the tree is "x - 20".

We can use the tangent function to set up two equations relating the height of the tree to the angles of elevation:

tan(37°) = h/x ...(1)

tan(52°) = h/(x - 20) ...(2)

We can solve this system of equations to find the value of "h". First, we can rearrange equation (1) to get:

x = h/tan(37°)

Then, we can substitute this expression for "x" into equation (2) and solve for "h":

tan(52°) = h/(h/tan(37°) - 20)

Simplifying and solving for "h", we get:

h = (20 tan(52°) tan(37°)) / (tan(52°) - tan(37°))

Using a calculator, we can evaluate this expression and find that:

h ≈ 50.6 ft

Therefore, the height of the tree is approximately 50.6 feet.

In right angle triangle ΔXYZ  in which ∠XYZ = 90° and ∠XZY i= 25°.

YZ =  33 inch, the length of XZ to the nearest hundredth is approximately 13.99 inches.

A trigonometric function is a mathematical function that relates the angles of a right triangle to the ratios of its sides. Three basic trigonometric functions are sine (sin), cosine (cos), and tangent (tan).

In a right triangle, if one angle is θ (where θ is not the right angle), then we can define the following trigonometric functions:

sine of θ (sin θ): the ratio of the length of the side opposite θ to the length of the hypotenuse

cosine of θ (cos θ): the ratio of the length of the adjacent side to the length of the hypotenuse

tangent of θ (tan θ): the ratio of the length of the side opposite θ to the length of the adjacent side

We can use the trigonometric function sine to relate the lengths of the sides in the right triangle XYZ. In particular, we know that:

sin(25°) = XZ / 33

To solve for XZ, we can multiply both sides by 33 and simplify:

XZ = 33 sin(25°)
