Step-by-step explanation:

Speed is the ratio of distance and time. When we divide f(x) by g(x) we will get the speed of the flock that is 9 miles/hour.

Speed can be defined as the rate of change in the position of an object. It is given as,

[tex]Speed = \dfrac{Distance}{Time}[/tex]

Given to us

Distance traveled, f(x) = 2x+26

Time, g(x) = x − 1

As we know that the ratio of distance and time is equal to the speed of the object. Since the distance traveled by the flock of birds is given also, the time needed for them to travel the distance is also given.

We need to find f divided by g of 5, which is the speed of the flock,

[tex]Speed = \dfrac{Distance}{Time} = \dfrac{f(x)}{g(x)}[/tex]

[tex]Speed = \dfrac{f(x)}{g(x)} = \dfrac{2x +26}{x-1}[/tex]

[tex]Speed = \dfrac{f(5)}{g(5)} = \dfrac{2(5) +26}{(5)-1}\\\\Speed = 9 \rm\ miles/ hour[/tex]

Hence, when we divide f(x) by g(x) we will get the speed of the flock that is 9 miles/hour.

Fraction is a quantity representing part of a hole. The specified fraction's quotient is obtained as: Option A: -343

If we have [tex]a^b[/tex], then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).

Exponentiation(the process of raising some number to some power) have some basic rules as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\ a^b \times a^c = a^{b+c}[/tex]

For given case, the quotient of fraction is obtained as:

[tex]\dfrac{(-7)^2}{(-7)^{-1}} = (-7)^2 \times (-7)^{-(-1)} = (-7)^{(2 + 1)} = -7^3 = -343[/tex]

The hydrostatic force is given by the integral of the force acting on

small horizontal strips from the base to the top of the triangle.

Response:

The given parameters are;

Base of the triangle = 6 m

Height of the triangle = 15 m

Acceleration due to gravity, g ≈ 9.8 m/s²

Weight density of water, ρ ≈ 1,000 kg/m³

Required:

Hydrostatic force on one side of the plate

Solution:

Considering a thickness, dx, having area, dA = y·dx

The pressure on the strip = ρ·g·x

Force on the strip, dF = ρ·g·x·y·dx

Using similar triangles, we have;

[tex]\dfrac{x}{15} = \dfrac{y}{6}[/tex]

Which gives;

[tex]y = \dfrac{x}{15} \times 6 = \mathbf{ \dfrac{2}{5} \cdot x}[/tex]

Therefore;

[tex]dF = \rho \cdot g \cdot x \cdot \dfrac{2}{5} \cdot x \cdot dx = \mathbf{\rho \cdot g \cdot x^2 \cdot \dfrac{2}{5} \cdot dx}[/tex]

Which gives;

[tex]F =\displaystyle \int\limits^{15}_0 { \rho \cdot g \cdot x^2 \cdot \dfrac{2}{5} } \, dx = \mathbf{\left[\rho \cdot g \cdot x^3 \cdot \dfrac{2}{3\times 5} \right]^{15}_0}[/tex]

Therefore;

[tex]F = \rho \cdot g \cdot \left[x^3 \cdot \dfrac{2}{3\times 5} \right]^{15}_0 = \mathbf{ \rho \cdot g \times 15^3 \cdot \dfrac{2}{3\times 5}} = 450 \cdot \rho \cdot g[/tex]

Which gives;

F = 450 m³ × 1,000 kg/m³ × 9.8 m/s² = 4,410,000 N = 4.41 MN

The volume of the ball is 636.38 cm^3. Option C shows the correct volume of the ball.

The volume of the sphere is defined as the amount of space occupied within the sphere. It is a space occupied by a three-dimensional object.

Given that the thickness of the ball is 2 cm and the outer radius r2 of the ball is 6 cm. The inner radius r1 of the ball is the difference between the outer surface and the thickness of the material.

r1 = 6-2

r1 = 4cm

The volume of the sphere ball is given as,

[tex]V = \dfrac {4}{3}\pi r^3[/tex]

For the inner radius, the volume is given as,

[tex]V_1 = \dfrac {4}{3}\times 3.14\times (4)^3[/tex]

[tex]V_1 = 267.94 \;\rm cm^3[/tex]

For the outer radius, the volume is given as,

[tex]V_2= \dfrac {4}{3}\times 3.14\times (6)^3[/tex]

[tex]V_2 = 904.32\;\rm cm^3[/tex]

The final volume of the ball is the difference between the volume of the inner and outer surface.

[tex]V = V_2 - V_1[/tex]

[tex]V = 904.32- 267.94[/tex]

[tex]V = 636.38 \;\rm cm^3[/tex]

Hence we can conclude that the volume of the ball is 636.38 cm^3. Option C shows the correct volume of the ball.

Answer:

The positions of your north celestial pole and south celestial pole change as you change latitude on the Earth, as you move north or south. At the Earth's equator, the Celestial Equator is directly overhead, and the poles are on opposite sides of the horizon. All stars are visible as they rise, culminate at the meridian, and set. As you move north, the Celestial Equator mirrors your movement, moving south the same number of degrees away from the zenith. The altitude of any star will change with the observer's latitude (as well as the time of night).

Note: only the altitude of the star changes NOT their coordinates. The star's celestial coordinates remain the same.

Step-by-step explanation:

Declination is measured in degrees north (+) or south (-) of an imaginary line called the Celestial Equator (CE). The Celestial Equator is the projection of the Earth's Equator onto the Celestial Sphere. The CE has a declination of 0 degrees, by definition. At dec = +90 degrees (90 degrees N) is the North Celestial Pole (NCP), the projection of the Earth's North Pole onto the Celestial Sphere. The South Celestial Pole (SCP) is at dec = -90 degrees.

An Example would be:

You move 30 degrees North of the equator, hence, the Celestial Equator has moved away from the zenith, 30 degrees to the south.

While the NCP has risen 30 degrees into the sky and the SCP has sunk 30 degrees below the horizon.

If you moved south, the opposite would have occurred as the Celestial Equator moved north of the zenith.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Let, the number be = x

1) The value of __ divided by 32 is less that 1 that is :

x/32 < 1

x < 32

Any number less then 32 when divided by 32 will be less that 1.  

2)  The value of __ divided by 32 is equal to 1 that is :

x/32 = 1

x = 32

32 when divided by 32 will be equal to 1.

Therefore, the number will be :

1) Any number less then 32 when divided by 32 will be less that 1.  

2) 32 when divided by 32 will be equal to 1.

Answer:

x = 5

Step-by-step explanation:

Set up proportion and cross multiply to solve:

9/2x-1 = 15/3x

x = 5

Answer:

Step-by-step explanation:

An angle bisector divides the base into ratios obtained by the sides of the triangle that are not divided. So

9/(2x - 1) = 15/3x                  Divide 3 into 15

9/(2x - 1) = 5/x                     Cross multiply

9x = 5(2x - 1)                        Remove the  brackets

9x = 10x - 5                          Switch sides.

10x - 5 = 9x                          Subtract 9x from both sides

10x - 9x - 5 = 0                    Combine

x - 5 = 0                               Add 5 to both sides.

x = 5
