Answer:

A differential equation of the form: [tex]dy/dx = f(x, y)[/tex] is [tex]\frac{-x}{y+2}[/tex]

Step-by-step explanation:

Step 1 of 3

a) Acceleration[tex]$\rightarrow v^{\prime}(t)$[/tex]

velocity [tex]$\rightarrow v(t)$[/tex]

Given that [tex]$v^{\prime}(t) \propto v^{2}(t)$[/tex]

[tex]\frac{d v}{d t}=k v^{2}[/tex]

[tex]k[/tex]  is proportionality constant.

Step 2 of 3

b) The population of Zootopia in year [tex]$t$[/tex], is [tex]$P(t)$[/tex]

Let [tex]$\beta$[/tex] the 'birth rate of Animals and [tex]$\delta$[/tex] the death rate of the population.

Then the population model is

[tex]\frac{d p}{d t}=(\beta-\delta) P$$[/tex]

Given that [tex]$\beta=50000$[/tex] and

[tex]$\delta=40000$[/tex]

So, [tex]$\frac{d P}{d t}=10000 P$[/tex]

Step 3 of 3

c) First we take the derivative of [tex]$f(x)$[/tex] i. e [tex]$f^{\prime}(x)$[/tex].

The evaluate it at [tex]$m_{1}=f^{\prime}(2)[/tex]

[tex]m_{2}=\frac{-1}{f^{\prime}(2)}$[/tex]

The normal line with slope [tex]$\frac{-1}{f^{\prime}(2)}$[/tex]

[tex]y-(-2)=\frac{-1}{f^{\prime}(2)}(x-0) \\[/tex]

[tex]y+2=\frac{-x}{f^{\prime}(2)}[/tex]

[tex]f^{\prime}(2)=\frac{f x}{(y+2)} \\[/tex]

[tex]&f^{\prime}(2)+\frac{x}{(y+2)}=0[/tex]

[tex]\frac{d y}{d x}=\frac{-x}{y+2}[/tex]

Answer:

[tex] {g}^{2} - 9g + 14[/tex]

Step-by-step explanation:

[tex](g - 7)( - 2)[/tex]

[tex]g \times ( g- 2) - 7(g - 2)[/tex]

[tex] {g}^{2} - 2g - 7g + 14[/tex]

[tex] {g}^{2} - 9g + 14[/tex]

therefore , correct option in A

Answer:

- 3

Step-by-step explanation:

Given

7 - 2h ( substitute h = 5 into the expression )

= 7 - 2(5)

= 7 - 10

= - 3

On evaluating the function at h = 5, we get -

f(5) = - 3.

We have a function -

f(h) = 7 - 2h

We have to find the value of f(h) at h = 5.

f(x) = Sin( [tex]\frac{\pi }{x}[/tex] )

f(2) = Sin( [tex]\frac{\pi }{2}[/tex] )

f(2) = 1

According to the question, we have -

f(h) = 7−2ℎ

Now, evaluating the function at h = 5, we get -

f(5) = 7 - 2 x 5 = -3

Hence, on evaluating the function at h = 5, we get -

f(5) = - 3.

Answer:

Step-by-step explanation:

The digital roots of the single-digit numbers 1-9 are just those numbers.

For numbers 10-18, the digits are the numbers 1-9, as for the numbers 19-27. In short, the digital root values are sequential, matching the remainder from division by 9 (except that numbers evenly divisible by 9 have a digital root of 9).

We also note that numbers divisible by 3 will have a digital root that is divisible by 3.

So, the patterns we notice are ...

_____

Additional comment

This is a consequence of our base-10 number system and modulo arithmetic. In a base-N number system, the "digital root" will be the value of the number modulo (N-1), again with the exception that 0 is replaced by (N-1). Divisors of (N-1) will also be divisors of the number if they divide the digital root.

The Weight of man after diet is  9/10(k).

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

Given:

A man weighs k kg.

He goes on a diet and loses one-tenth of his weight.

So, the weight after diet is

= k - k(1/10)

= (10k - k)/ 10

= 9k /10

= 9/10(k)

Answer:

vertex = (2, - 1 )

Step-by-step explanation:

Given a parabola in standard form

f(x) = ax² + bx + c ( a ≠ 0 ) , then

The x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

f(x) = x² - 4x + 3 ← is in standard form

with a = 1, b = - 4 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{-4}{2}[/tex] = 2

Substitute x = 2 into f(x) for corresponding y- coordinate

f(2) = 2² - 4(2) + 3 = 4 - 8 + 3 = - 1

vertex = (2, - 1 )
