Answer:
Here is the full question:
Another plan to secure the roller coaster involves placing two concrete struts on either side of the center of the leg of the roller coaster to add reinforcement against southerly winds in the region. Again, using the center of the half-circle as the origin, the struts are modeled by the equations and . A vertical reinforcement beam will extend from one strut to the other when the two cables are 2 feet apart.
Graph the two struts on the model of the roller coaster. Take a screenshot of your graph and paste the image below, or sketch a graph by hand.
Recall that a reinforcement beam will extend from one strut to the other when the two struts are 2 feet apart.
(a) Algebraically determine the x -value of where the beam should be placed.
(b) Explain where to place the beam
Step-by-step explanation:
Find attached the graphing calculator.
(a) The x-value where the beam should be placed is x = -4
(b) The beam should be placed directly above 4 feet from the center.
Answer:
Theresa's height is 60 inches
Step-by-step explanation:
The given parameters are;
The height of Paul = The height of Steve
Paul's height = times Theresa's height - 16 inches
Steve's height = times Theresa's height - 6 inches
Let 'T' represents Theresa's height, we have;
Paul's height = ×T - 16
Steve's height = ×T - 6
Paul's height = Steve's height
Therefore;
×T - 16 =
×T - 6
×T -
×T = 10
×T -
×T = 10
×T = 10
T = 10 × 6 = 60
Theresa's height, T = 60 inches
The true statement about the graph from the attached image below is: The material's temperature reaches a minimum at 15 hours.
<h3>What is the parabolic graph of the quadratic equation?</h3>The parabolic graph is a curved U-shaped graph that is established from a quadratic equation.
The parabola of the graph can be downward creating a maximum or upward (minimum).
From the given image, the correct interpretation shows that as a result of cryogenic treatment, the material's temperature reaches a minimum at 15 hours.
