trapecia [35]

Answer:

(a) 3118=61*t

(b) The amount of time the roller coaster is in motion is 51.11 seconds.

Step-by-step explanation:

Speed is a magnitude that expresses the relationship between the space traveled by an object, the time used for it and its direction. In other words, speed is associated with the change in position of a body over time and can be expressed as:

$speed=\frac{distance}{time}$

Then the distance traveled can be expressed as:

distance=speed*time

(a) If x represents the total time that the roller coaster is in motion for each ride, the average speed is 61 feet per second and the distance is 3118 feet then the expression to represent the situation is:

<u><em>3118=61*x</em></u>

(b) To calculate the amount of time the roller coaster is moving, you simply need to solve the expression found in (a). Dividing 61 to both sides:

$\frac{3118}{61} =\frac{61*x}{61}$

51.11 seconds=x

<u><em> The amount of time the roller coaster is in motion is 51.11 seconds.</em></u>

Name a point that is between 50 and 60 units away from (7,-2) and state the distance between the two points.

laila [671]

Let the required point be (a,b)

The distance of (a,b) from (7,-2) is

= $\sqrt{(a-7)^2+(b+2)^2}$

But this distance needs to be betweem 50 & 60

So

$50$

Squaring all sides

2500 < (a-7)² + (b+2)² < 3600

Let a = 7

So we have

2500 < (b+2)² <3600

b+2 < 60 or b+2 > -60 => b <58 or b > -62

Also

b+2 >50 or b + 2 < -50 => b >48 or B < -52

Let us take one value of b < 58 say b = 50

So now we have the point as (7, 50)

The other point is (7,-2)

Distance between them

= $\sqrt{(7-7)^2+(50+2)^2}= \sqrt{(52)^2}=52$

This is between 50 & 60

Hence one point which has a distance between 50 & 60 from the point (7,-2) is (7, 50)
