A cylinder has a height of 9 yards and a radius of 8 yards. What is its volume? Use ​ ≈ 3.14 and round your answer to the nearest hundredth.

Answer:

141°

Step-by-step explanation:

An octagon has 8 sides and 8angles so the sum of its interior angles is: (8-2)×180= 1080°

5x+133+16+126+162-12+30=1080°

5x=625

x=125°

x+16=141°

Step-by-step explanation:

f=ka

36=9k

k=4

f=4×4

f=16

Answer:

The vertex is (5, -9).

Step-by-step explanation:

One way of approaching this problem consists of finding the roots.  Seet the quadratic equal to zero and solve for x:  {2, 8}.

The axis of symmetry is exactly halfway between 2 and 8:  x = 5.

Now find the y-component of the vertex by evaluating f(5):

f(5) = (5 - 8)(5 - 2) = -9

The vertex is (5, -9).  This is the minimum value of the function.  The graph of this quadratic opens up.

Answer:

4π

Step-by-step explanation:

the area (A) of each shaded sector is calculated as

A = area of circle × fraction of circle

the angle subtended at the centre of each sector = 180° - 160° = 20°

then area of 2 sectors

= 2 × π × 6² × [tex]\frac{20}{360}[/tex]

= 2 π × 36 × [tex]\frac{20}{360}[/tex]

= 2π × [tex]\frac{20}{10}[/tex]

= 2π × 2

= 4π

Answer:

4.5 > x

Step-by-step explanation:

19 > 2x + 10

19 - 10 > 2x + 10 - 10

9 > 2x

9/2 >2x/2

9/2 > x

or

4.5 > x

[tex]98n + 78 {x}^{2} (9)n - 36x[/tex]

the simplest form.

[tex]98n + 78 {x}^{2} (9)n - 36x[/tex]

[tex] = 98n + 702 {nx}^{2} + - 36x[/tex]

[tex] = 702 {nx}^{2} + 98n - 36x[/tex]

Answer:

The measure of dispersion that is influenced most by extreme values is range.

Step-by-step explanation:

Range is the most simple and commonly understandable measures of dispersion. Range is defined as the difference between the highest and lowest observed value in a series.

Using translation concepts, it is found that the transformations necessary to transform the graph of f(x) into that of g(x) are given as follows:

Answer:

11 over 20

Step-by-step explanation:

There are 20 altogether and 9 are green and red 20 - 9 = 11

Step-by-step explanation:

the slope is always the ratio "y coordinate change / x coordinate change" when going from one point of the line to another.

so, when going from (-2, 3) to (-3, 1)

x changes by -1 (from -2 to -3).

y changes by -2 (from 3 to 1).

therefore, the slope is

-2/-1 = 2/1 = 2

An expression is defined as a set of numbers, variables, and mathematical operations. The simplification of the expression (5x/x^2-1 )×(x+1/x^2) is 5/x(x-1).

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The simplification of the given expression can be done as,

[tex]\dfrac{5x}{x^2-1} \times \dfrac{x+1}{x^2}\\\\=\dfrac{5x}{x^2-1^2} \times \dfrac{x+1}{x^2}\\\\=\dfrac{5x}{(x+1)(x-1)} \times \dfrac{x+1}{x^2}\\\\= \dfrac{5}{(x-1)x}[/tex]

Hence, the simplification of the expression (5x/x^2-1 )×(x+1/x^2) is 5/x(x-1).

The equation that models the exponential decline is y = 46348587109809610(0.9861)ˣ if the population over the past 20 years is provided.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

Let's suppose the equation that models the exponential decline is:

[tex]\rm y = a(b^x)[/tex]

From the data given, we can calculate the value of a and b:

a = 46348587109809610

b = 0.9861

y = 46348587109809610(0.9861)ˣ

Thus, the equation that models the exponential decline is y = 46348587109809610(0.9861)ˣ if the population over the past 20 years is provided.

if the previous digit is 5 or more round up, if not keep it as it is.

1 sf= 8000

therefore, 7874 rounded to 1 sf is 8000.

Answer:

8000
