Answer:
The expression is d=v+15
Step-by-step explanation:
Given that The center of the Ferris wheel is 15 meters above the ground and the radius of the Ferris wheel is 10 meters. Kristin Boards the Ferris wheel at 3-o’clock position and rides the Ferris wheel for one full rotation.
Also, The variable v represents Kirsten’s height above the center of the Ferris wheel then we have to find the expression using v that represents Kristin’s height above the ground in meters.
Let the Kirsten's is at the point P. Now, we have to find the vertical distance from the ground to write the expression.
Vertical distance=The center of the Ferris wheel above the ground+Kirsten’s height above the center of the Ferris wheel
⇒ d=v+15
where v is independent variable and d is dependent variable.
Domain of v lies between [15,25]
Kristen's height above the center of the Ferris wheel is given as the variable
v, therefore, her height above the ground is v + 15 meters.
Reasons:
Height of the center of the Ferris wheel above the ground, h = 15 m.
Radius of the Ferris wheel = 10 m.
Location Kristin boards the Ferris wheel = 3-O'clock
Kristin's height above the center of the Ferris wheel = v
Therefore;
The expression for Kirsten's height above the ground is 15 + v
Kirsten's varying height above the ground, d, in terms of v is given as follows;
d = 15 + v
