Answer:

240 s or 4 min

Step-by-step explanation:

If the car was at rest ;

u = 0

a = 5m/s²

v = 48 m/s

t = ? (to be found)

By formula ,

a = \displaystyle\frac{v - u}{t}

a = \displaystyle\frac{48 - 0}{t}

a = \displaystyle\frac{48}{t}

5 \ m/s^2 × 48 \ m/s = t

t = 240 \ s

Answer:  The required solution is

y=(-2+t)e^{-5t}.

Step-by-step explanation:   We are given to solve the following differential equation :

y^{\prime\prime}+10y^\prime+25y=0,~~~~~~~y(0)=-2,~~y^\prime(0)=11~~~~~~~~~~~~~~~~~~~~~~~~(i)

Let us consider that

y=e^{mt} be an auxiliary solution of equation (i).

Then, we have

y^prime=me^{mt},~~~~~y^{\prime\prime}=m^2e^{mt}.

Substituting these values in equation (i), we get

m^2e^{mt}+10me^{mt}+25e^{mt}=0\\\\\Rightarrow (m^2+10y+25)e^{mt}=0\\\\\Rightarrow m^2+10m+25=0~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[\textup{since }e^{mt}\neq0]\\\\\Rightarrow m^2+2\times m\times5+5^2=0\\\\\Rightarrow (m+5)^2=0\\\\\Rightarrow m=-5,-5.

So, the general solution of the given equation is

y(t)=(A+Bt)e^{-5t}.

Differentiating with respect to t, we get

y^\prime(t)=-5e^{-5t}(A+Bt)+Be^{-5t}.

According to the given conditions, we have

y(0)=-2\\\\\Rightarrow A=-2

and

y^\prime(0)=11\\\\\Rightarrow -5(A+B\times0)+B=11\\\\\Rightarrow -5A+B=11\\\\\Rightarrow (-5)\times(-2)+B=11\\\\\Rightarrow 10+B=11\\\\\Rightarrow B=11-10\\\\\Rightarrow B=1.

Thus, the required solution is

y(t)=(-2+1\times t)e^{-5t}\\\\\Rightarrow y(t)=(-2+t)e^{-5t}.

ivolga24 [154]

Answer:

The correct option is - content analysis

Step-by-step explanation:

Dr. Jones is having his students use: content analysis.

Content analysis is a type of research technique, where we make similar and valid inferences by coding and interpreting information in text forms.

Here Dr. Jones is asking his students to gather information to identify the violent acts in each cartoon show. So, the students will be gathering content or information and then they will come to some inference.

How do you graph y=2x-10
bixtya [17]
One of the easier approaches would be that of x- and y-intercepts.

Setting x=0 results in y=-10; the y-intercept is (0, -10).
Setting y = 0 results in x = 5, so the x-intercept is (5,0).

Plot these 2 points.  Then draw a str. line thru these points.
