Mathematics

vampirchik [111]3 years ago
8 0

Answer:

Step-by-step explanation:

because The curve C crosses the x-axis at the origin and at the points A and B =>  the x coordinates of A and B are the solution of the equation:

 x(x + 4)(x - 2) = 0

<=> x = 0

      x = -4

      x = 2

because the x-coordinates of the points A and B aren't 0 and the x-coordinate

of A is a negative value

=>  the x-coordinate of  A is -4

the x-coordinate of B is 2

Tomas and Tasha were hiking at a speed of 3.5 mph. On their way back, they were tired and their speed was 2 mph. How long was th
Anna35 [415]

 To get the length of the route use the expression for speed,

Distance = Speed × Time

Length of the route is 7 miles.

It's given in the question,

 Speed of Tomas and Tasha initially = 3.5 mph

Therefore, distance travelled by both with the speed of 2 mph one way will be,

 Distance = 3.5t [Here, t = time ]

Speed of both while coming back = 2 mph

And the time taken = t + (1 hour 30 minutes)

                                 = (t + 1.5) hours

Therefore, distance travelled while coming back = Speed × Time

                                                                                  = 2(t + 1.5)

Since, length of the route is same both ways,

3.5t = 2(t + 1.5)

3.5t = 2t + 3

3.5t - 2t = 3

1.5t = 3

t = 2 hours

Now substitute the value of t in the expression to get the distance of the route,

Distance = 3.5t

               = 3.5 × 2

               = 7 miles

 Therefore, route was 7 miles long.
