We looking for distance
drek231 [11]

Answer:

240 m

Step-by-step explanation:

Figure is attached.

The distance the particle travels is the area under the v-t graph over the time interval from 0 min to 4 min.  The reason you can't just multiply velocity by time is that the velocity is changing at a constant rate over the given time interval (the line is going upward--the particls is speeding up).

What's the area under the graph?

The red outline forms a trapezoid.  The area of a trapezoid is  A=\frac{1}{2}h(b_1+b_2)  where the <em>b</em>'s are the lengths of the two parallel base and  <em>h</em>  is the height (the distance between the bases).

Reading the graph carefully (notice the scales!)...

A=\frac{1}{2}(4)(30+90)=(2)(120)=240 \text{m}

What is the equation of the following graph?
ser-zykov [4K]

Answer:

y=0.5x + 5

Step-by-step explanation:

The points are (0,5) and (-10,0)

to find the slope do

0-5/-10-0 = 5/10 = 1/2 = 0.5

next plug one of the points into point slope formula

y-y1=m(x-x1)

lets use the point (-10,0)

y1=0

x1= -10

m= 0.5

y-0=0.5(x- -10)

y = 0.5(x+10)

distribute the 0.5

y=0.5x+5

PLEASE HELP!!!! A boat can travel at an average speed of 10 miles per hour in still water. Traveling with the current, it can tr
Soloha48 [4]

Answer:

  • 2 mph

Step-by-step explanation:

Let the speed of current be x

<u>Speed of the boat in same direction as current is</u>

  • 10 + x

<u>Speed against the current is</u>

  • 10 - x

<u>Based on the given we get the equation for time</u>

  • 6/(10 + x) = 4/(10 - x)

<u>Solving for x</u>

  • 6(10 - x) = 4(10 + x)
  • 60 - 6x = 40 + 4x
  • 6x + 4x = 60 - 40
  • 10x = 20
  • x = 2

The answer is 2 mph
