Answer:
Step-by-step explanation:
x = time
y = elevation
At x = 0 , y = 0
It takes the submarine 2 hours to make descent of 2100 ft
=> x = 2 , y = - 2100
Slope = ( -2100 - 0)/(2 - 0) = -1050
y - 0 = -1050 ( x -0)
=> y = -1050x
1050x + y = 0
represent the relationship between the submarine's elevation and time.
Answer: OPTION C.
Step-by-step explanation:
Given a function f(x), the range of the inverse of f(x) will be the domain of the function f(x) and the range of the domain of f(x) will be the range of the inverse function.
For example, if the point (2,1) belongs to f(x), then the point (1,2) belongs to the inverse of f(x).
Observe that in the graph of the function f(x) the point (-3,1) belongs to the function, then the point (1,-3) must belong to the inverse function.
Therefore, you need to search the option that shown the graph wich contains the point (1,-3).
Observe that the Domain f(x) is (-∞,0) then the range of the inverse function must be (-∞,0).
This is the graph of the option C.
Answer:
115.2 inches
Step-by-step explanation:
What we must do is calculate the ratio between the real version and the version to be imitated, in this case the ice cream cone.
To calculate the ratio, we will do it through the diameter:
48 / 2.5 = 19.2
So the ratio is 19.2: 1
Which means that one inch of the ice cream cone represents 19.2 inches in the real version.
Therefore, in the case of height it would be:
6 * 19.2 = 115.2
Therefore, the height should be 115.2 inches.
