please answer these to with working​

(i) Velocity is the rate of change of position, so if

r(t) = b cos(ω t ) i + b sin(ω t ) j + v t k

then

v(t) = dr/dt

v(t) = -b ω sin(ω t ) i + b ω cos(ω t ) j + v k

The speed of the particle is the magnitude of the velocity, given by

|| v(t) || = √[(-b ω sin(ω t ))² + (b ω cos(ω t ))² + v ²]

… = √[b ²ω ² + v ²]

(ii) The path is a helix. Suppose you zero out the k component. Then the path is a circle of radius b, and the value of ω determines how quickly a particle on the path traverses the circle. Now if you reintroduce the k component, the value of v will determine how far from the plane z = 0 the particle moves in a helical path as t varies.

(iii) Acceleration is the rate of change of velocity, so

a(t) = dv/dt

a(t) = -b ω ² cos(ω t ) i - b ω ² sin(ω t ) j

Answer:

x = 3

AB = 18

Step-by-step explanation:

Based on the midsegment theorem:

[tex] MN = \frac{1}{2}(AB) [/tex]

MN = 9

AB = x + 15

Plug in the values and solve for x

[tex] 9 = \frac{1}{2}(x + 15) [/tex]

Multiply both sides by 2

[tex] 9 \times 2 = \frac{1}{2}(x + 15) \times 2 [/tex]

[tex] 18 = x + 15 [/tex]

Subtract 15 from each side

[tex] 18 - 15 = x + 15 - 15 [/tex]

[tex] 3 = x [/tex]

x = 3

AB = x + 15

Plug in the value of x

AB = 3 + 15

AB = 18

Answer:

slope = 3

Step-by-step explanation:

to find the slope you do (y2-y1)/(x2-x1)=m

so we can plug the points into this formula

(5,7)     (2,-2)

x1 y1    x2 y2

-2-7/2-5=m

-9/-3=m

Simplifies to

3=m

Note: Your equation seems a little unclear. But, I am assuming that your equation is:

[tex]e^x\:+\:e^{-1}=\:2[/tex]

Because my solution would still clear your concept about this topic, no matter what the question is.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the equation

[tex]e^x\:+\:e^{-1}=\:2[/tex]

subtract [tex]e^{-1}[/tex] from both sides

[tex]e^x+e^{-1}-e^{-1}=2-e^{-1}[/tex]

[tex]e^x=2-\frac{1}{e}[/tex]

[tex]\ln \left(e^x\right)\:=\ln \:\left(2-\frac{1}{e}\right)[/tex]

[tex]\:x\cdot ln\left(e\right)=\ln \:\:\left(2-\frac{1}{e}\right)[/tex]

[tex]\:x\cdot 1=\ln \:\left(2-\frac{1}{e}\right)[/tex]       ∵ [tex]\:\:\ln \left(e\right)=1[/tex]

[tex]x=\ln \:\left(2-\frac{1}{e}\right)[/tex]

Answer:

Step-by-step explanation:

If 'a' adult tickets are sold for $11 each, the amount of money they sold for is ...

  11a

If 'c' children's tickets are sold for $5 each, the amount of money they sold for is ...

  5c

Then the expression for the total amount from the sale of tickets is ...

  11a +5c . . . . total of money raised

__

The value of this expression for a=247 and c=390 is ...

  11·247 +5·390 = 2717 +1950 = 4667

A total of $4667 was raised by the sale of tickets.

Step-by-step explanation:

Answer:

In exchange for rent/royalty, wages/salaries, interest, and profit. All of which accrue to households, for the FOP they sell.

Step-by-step explanation:

In the Circular Flow of Income model, the movement of money and resources is described/illustrated.

The factor market is the arrangement where factors of production are bought and sold. Remember that factors of production are classified into 4 groups:

- land  - labor  - capital  - entrepreneur

In a 2-sector economy, the players in the circular flow model will be Households & Firms

The factor market of the CFM will have households providing the factors of production and firms purchasing the factors of production.

So in the factor market of the CFM, firms receive factors of production from households, in exchange for payments such as rent (for land), income (for labor), interest (for capital), and profit (for entrepreneurial/management skills).

Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

[tex]3x - 5 = 10[/tex]

We want to isolate the x.

[tex]3x - 5 = 10\\+5\;\;\;\;\;\;\;\;\; +5[/tex]

[tex]3x = 15[/tex]

Now, we want the x not to have a coefficient. We want it just to be x =. We will do this via inverse operations. Since 3 x is 3 multiplied by x, we will divide each side by 3.

[tex]\frac{3x}{3} \;=\;\frac{15}{3}[/tex]

[tex]x = 5[/tex]

Step-by-step explanation:

5. 235 per second

5 x 235 = 1,175

Expression: y = 235x

Answer:

x = 9

Step-by-step explanation:

First equation = 4x - 8

Second equation = 7x - 35

Seperate the equation with an equal sign to make it an equality equation and solve for X so :

4x - 8 = 7x - 35 (Given)

-3x - 8 = -35 (Subtraction property of equality)

-3x = -27 (Addition property of equality)

x = 9 (Division property of equality)

Solution:

x = 9
