Step-by-step explanation:
Formula for volume of a cuboid . where l is the length, w is the width and h is the height.
Using this equation we can answer the question by using the values given.
From the list of answers, we can compare each one to the answer we got and see if they match up.
The answers that match up are:
C. - it is exactly like the answer we got.
D. - if we simplify the brackets, it is exactly like the answer we got.
E. - once again, if we simplify the brackets it is like the answer we got.
None of the other answers are correct as they do not match up with the answer we got.
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.
