Answer:
Step-by-step explanation:
If y is directly proportional to x, then the formula for that is a linear one:
y = kx, where k is the constant of proportionality. In our situation, if the pressure is directly proportional to the temp, then our formula is
P = kT. We need to find that value of k. Plug in what we have:
6 = k(440) so
k = .01363636 or as an equivalent fraction,
Now that have that value of k, we can use it in the formula again, this time with a different value for T to solve for P.
so
P = 5.181818 or as an equivalent fraction,
Answer:
Second option: False
Step-by-step explanation:
You need to use the following identity:
Let be "x" the lenght of the buildings's shadow.
(Lenght of building's shadow)
You can observe in the figure that:
Substitute these values into and solve for ""x":
Therefore, the length of its shadow IS NOT 12.94 feet.
Correct question is;
Tanya walked for 17 minutes from her home to a friend that lives 1.5 kilometers away. D(t) models Tanyas remaining distance to walk in kilometers, t minutes since she left home. What number type is more appropriate for the domain of d?
Answer:
0 ≤ t ≤ 17 ; (0, 17)
Step-by-step explanation:
We are told that she has walked for 17 minutes from her home to a friend that lives 1.5 kilometers away.
Now, we want to find the domain of numbers that shows her remaining distance.
Since she spent 17 minutes, then it means in modeling remaining distance it could be from 0 to 17 minutes as the case may be. Thus, the domain can be written as;
0 ≤ t ≤ 17 ; (0, 17)
