Answer:

For y(-7) =6.4

        The  largest interval  is  between  

                                       -\infty \to -5

For   y(-2.5) = -0.5.

          The  largest interval  is  between  

                                        -5 \to 5

For  y(0) = 0

          The  largest interval  is  between  

                                        -5 \to 5

For y(4.5) = -2.1.

            The  largest interval  is  between  

                                        -5 \to 5

For y(14)= 1.7.

                          The  largest interval  is  between  

                                        9 \to \infty        

   

Step-by-step explanation:

From m the question we are told that

     The first order differential equation is   \frac{y' -  t}{ t^2 -25} =  \frac{e^t}{t-9}

Now the first step is to obtain the domain of the differential equation

Now to do that let consider the denominators

  Now generally

                           t^2 - 25 \ne  0                                           side calculation

                   =>     t\ne \pm5                                                      t^2 - 25 =  0

                                                                                          t = \pm 5

Also              t-9\ne 0                                                     t -9 = 0

        =>          t\ne 9                                                            t= 9    

This means that this  first order differential equation is discontinuous at

       t =  -5 ,  \   \  t =  5 \ \  t =  9

  This  \  is \  illustrated \  below    \  \\      ------------------\\\. \ \ \  | \ \ \   \ \ \   \ \ \ \  \ \ \ \ \ | \ \ \ \ \ \ \ \ \ \ \ \ \ |\\. \  -5 \ \ \ \ \  \ \ \ \ \ \ \  5 \ \ \ \ \ \ \ \ \ \ \ \ \   9

So

For y(-7) =6.4

        The  largest interval  is  between  

                                       -\infty \to -5

For   y(-2.5) = -0.5.

          The  largest interval  is  between  

                                        -5 \to 5

For  y(0) = 0

          The  largest interval  is  between  

                                        -5 \to 5

For y(4.5) = -2.1.

            The  largest interval  is  between  

                                        -5 \to 5

For y(14)= 1.7.

                          The  largest interval  is  between  

                                        9 \to \infty

How do you find out if a like is parallel, perpendicular, or coincidental when theres 2 equations
finlep [7]

The slope intercept form of the equation of a line is given as:

y = mx + c

where m = the slope of the line

c = the y - intercept of the line

1) Two line are parallel if they have the same slope

That is:

\begin{gathered} \text{If the equation for line 1 is: y = m}_1x+c_1 \\ \text{If the equation for line 2 is:  y = m}_2x+c_2 \\ \text{Then, line 1 is parallel to line 2 if m}_1=m_2 \end{gathered}

2) Two equations are perpendicular if the slope of one is the negative inverse of the other.

\text{That is : m}_1=\text{ }\frac{-1}{m_2}

3) Two equations are coincidental if they have the same slope and the same y intercept

\begin{gathered} \text{That is: m}_1=m_2_{} \\ \text{and c}_1=c_2 \end{gathered}

What is the y-intercept of the graph of the given line by the equation 3y+4x=15?
serg [7]
In y-intercept: x=0. Hence:

3y+4\cdot0=15\iff 3y=15\iff \boxed{y=5}

The intersection is the point P(0,5)\Longrightarrow \boxed{\boxed{A}}

In the supermarket there is a scale that measures the weight of fruit and vegtsbles. The nedle is 24 cm long and it roatated 96d
Galina-37 [17]

Answer:

The distance of needle cover as it rotate is 0.700688 cm

Step-by-step explanation:

Given as :

The length of the needle = r = 24 cm

The needle is rotated at angle = Ф = 96°

The distance of needle cover as it rotate = length of arc made = l cm

The radius of arc = length of needle = r cm

<u>Now, According to question</u>

The distance of needle cover as it rotate = \dfrac{\Pi \times radius\times \Theta }{180^{\circ}}

where , π = 3.14

Or, l = \dfrac{\Pi \times r\times \Theta }{180^{\circ}}

Or, I = \dfrac{3.14 \times 24 cm\times 96^{\circ} }{180^{\circ}}

Or, l = 75.36 × 0.533°

∵ 180° = 3.14 radian

So, 0.533° = 0.0092978

So,  l = 75.36 × 0.0092978

∴   l = 0.700688 cm

So,The distance of needle cover as it rotate = l = 0.700688 cm

Hence, The distance of needle cover as it rotate is 0.700688 cm Answer
