The height of the cone in this problem is given as follows:

h = 16.4 units.

The volume of a cone of radius r and height h is given by the equation presented as follows:

V = πr²h/3.

The parameters for this problem are given as follows:

V = 2325 π, r = 15.

Hence the height is obtained as follows:

2325 = π x 15² x h/3

h = 2325 x 5/(15² x π)

h = 16.4 units.

Answer:

x = 2

y = -3

Step-by-step explanation:

y = x - 5

x + y = -1

To solve the given system of equations, we can use the method of substitution.

That is, you can replace y with ( x - 5 ).

x + y = -1

x + (x - 5 ) = -1

x + x - 5 = -1

Combine like terms.

2x - 5 = - 1

Add 5 to both sides.

2x = - 1 + 5

2x = 4

Divide both sides by 2.

x = 2

And now let us find the value of y by replacing x with 2.

y = x - 5

y = 2 - 5

y = -3

The expression 2log(5) can be rewritten as log(25) in the form log(c), representing the Logarithm to the base 10 that yields the value 25.

The expression 2log(5) in the form log(c), we can use the logarithmic property that states:

nlog(b) = log(b^n)

Applying this property, we can rewrite 2log(5) as:

2log(5) = log(5^2)

Simplifying further, we have:

2log(5) = log(25)

Therefore, the expression 2log(5) can be written in the form log(c) as log(25).

The logarithmic function log(c) represents the exponent to which a given base must be raised to obtain the value c. In this case, log(25) represents the exponent to which the base 10 must be raised to obtain the value 25.

In summary, the expression 2log(5) can be rewritten as log(25) in the form log(c), representing the logarithm to the base 10 that yields the value 25.

75,582 different groups of 8 can be formed from the 19 volunteers.

In this case, we want to calculate C(19, 8), which represents the number of ways to choose 8 volunteers from a set of 19 volunteers.

The formula for combinations is given by:

C(n, r) = n! / (r!(n-r)!)

Using this formula,

C(19, 8) = 19! / (8!(19-8)!)

C(19, 8) = 19! / (8!11!)

C( 19, 8) = 19 x 18 x 17 x 16 x 15 x 14 x 13 x 12 / 8 x7 x6 x 5x 4 x 3 x 2

Answer:reference angle shoudl be 156 degrees srry if im wrong :)

Step-by-step explanation:

The value of all three angles, A , B and C is 60°

All sides , a,b, and c are 7.5 inches

From Cosine Rule :

CosA = (b² + c² - a²)/(2bc)

CosA = (7.5² + 7.5² - 7.5²)/(2 × 7.5 × 7.5)

CosA = 56.25/112.5

CosA = 0.5

A =

[tex] {cos}^{ - 1} (0.5) = 60[/tex]

From Sine Rule a/sinA = b/sinB

7.5/Sin60° = 7.5/SinB

cross multiply

7.5SinB = 7.5(Sin60°)

sinB= 6.495/7.5

SinB = 0.866

B =

[tex] {sin}^{ - 1} (0.866) = 60[/tex]

A + B + C = 180

60 + 60 + C = 180

C = 180 - 120

C = 60°

A figure that is a dilation of figure A include the following: B. figure C.

In Geometry, a dilation is a type of transformation which typically transforms the dimension (size) or side lengths of a geometric object, without affecting its shape.

This ultimately implies that, the dimension (size) or side lengths of the dilated geometric object would be stretched or shrunk depending on the scale factor that is applied.

In this context, we can reasonably infer and logically deduce that both figure A and figure C are congruent to figure E because they all share a common center of dilation.

Missing information:

The question is incomplete and the complete question is shown in the attached picture.

Answer:21 cm.

Step-by-step explanation:

Para encontrar la longitud del lado de un cuadrado con un área de 441 cm², podemos usar la fórmula del área de un cuadrado.

El área de un cuadrado se calcula elevando al cuadrado la longitud de uno de sus lados, es decir, A = L², donde A es el área y L es la longitud del lado.

Dado que el área del cuadrado es 441 cm², podemos escribir la ecuación:

441 = L²

Para encontrar L, podemos tomar la raíz cuadrada de ambos lados de la ecuación:

√441 = √L²

21 = L

Por lo tanto, la longitud del lado de un cuadrado con un área de 441 cm² es de 21 cm.

The farmer sold 3.6 kilograms of apples at the farmers market.

To find the weight of apples the farmer sold at the farmers market, we need to subtract the weight of pears from the total weight.

We have,

3/5 of the weight is pears, the weight of pears

= (3/5) x 7.2 kilograms.

= 3.6 Kg

Since the remaining weight is apples, we can calculate the weight of apples by subtracting the weight of pears from the total weight:

Weight of apples = Total weight - Weight of pears

= 7.2 - 3.6

The length of the variable are as follows;

x = 27.4 units

y = 12.7 units

When two secants intersect outside a circle, the circle divides the secants into segments that are proportional with each other.

Therefore,

5(x + 5) = 6(21 + 6)

5x + 25 = 126 + 36

5x + 25 = 162

5x = 162 - 25

5x = 137

x = 137 / 5

x = 27.4 units

Let's find variable y as follows;

If a secant and a tangent are drawn to a circle from the same external point, the product of the length of the secant and its external segment equals the square of the tangent segment.

Therefore,

y² = (21 + 6)6

y² = 27 × 6

Answer: So the number is 24.

Step-by-step explanation:

The data set is approximately periodic with a period of 3 and an amplitude of about 7.5.

The period is the length of time it takes for the data to repeat itself. In this case, the data repeats itself every 3 hours. The amplitude is the distance between the highest and lowest values in the data set. In this case, the amplitude is about 7.5 cars.

Hour | Number of cars

------- | --------

1     | 90

2     | 52

3     | 76

4     | 75

5     | 91

6     | 104

8     | 105

9     | 119

10    | 103

11    | 121

12    | 135

As you can see, the data repeats itself every 3 hours. The highest value in the data set is 135 cars, and the lowest value is 52 cars. The difference between these two values is 83 cars, which is about 7.5 times the average number of cars (90 cars). Therefore, the amplitude of the data set is about 7.5 cars.

Step-by-step explanation:

The average value of the function over the interval is 0

From the question, we have the following parameters that can be used in our computation:

f(x) = √(49 - x²)

The interval is given as

From x = 0 to x = 7

The function is a square root function

Calculating f(0) and f(7), we have

f(0) = √(49 - 0²) = 7

f(7) = √(49 - 7²) = 0

Next, we have

Average value = (7 * 0 + 0 * 7)/(0 + 7)

Evaluate

Average value = 0

x - 3(9+7)x-(-3x) equals -43x, which is the answer we get after applying the order of operations.

To simplify this expression, we need to use the order of operations, which is PEMDAS (parentheses, exponents, multiplication and division, and addition and subtraction). We can simplify the expression step-by-step, following the rules of PEMDAS.
First, we need to simplify the parentheses, which contain an addition operation. We have:
x - 3(9 + 7)x - (-3x)
= x - 3(16)x + 3x   (remember that -(-3x) is the same as +3x)
= x - 48x + 3x     (multiplying 3 by 16 gives us 48)
= -44x + x
= -43x

Therefore, the expression x - 3(9+7)x-(-3x) simplifies to -43x.
In summary, x - 3(9+7)x-(-3x) equals -43x, which is the answer we get after applying the order of operations. Remember to follow the rules of PEMDAS carefully, and take your time simplifying each part of the expression.
