Answer:
- 0.25|h -1600| -400
- 1000
- 2200
Step-by-step explanation:
Once again, you can choose the correct equation by finding the one that gives d=0 for h=0. (Note that the problem statement requires the independent variable to be h, not x.)
Then you can use that equation to find h for d=-250:
-250 = 0.25|h -1600| -400
150 = 0.25|h -1600|
600 = |h -1600|
This resolves to two equations:
- -600 = h -1600 . . . ⇒ . . . h = 1000
- 600 = h -1600 . . . ⇒ . . . h = 2200

Or, you can realize the distance from the west end is 4 times the depth. At a depth of 250 ft, that distance is h=1000 ft. That is 600 ft from the center, so 1200 ft from the same depth on the other side of the crater, which is at h=2200 ft.
Answer:
Domain is all real numbers.
Step-by-step explanation:
Given:
The function is given as:
![f(x)=(x+7)^3-2](https://tex.z-dn.net/?f=f%28x%29%3D%28x%2B7%29%5E3-2)
A function is like a machine which gives an output for a given output.
The input to a function is called its domain. The domain is the set of all possible values for which the function is defined. The domain is represented by the independent variable 'x'.
The output of the function is the function value for the given 'x'. It is represented by 'y' or 'f(x)'.
So, the domain must include only those values which give a definite value for
.
Here, the given function is a cubic function. A cubic function is one which has the highest power of 'x' as 3. A cubic function is defined for all real values of 'x'.
Therefore, the domain of the given function is all real values.
Answer:
6 round trip visits
Step-by-step explanation:
25 min drive to the store + 3 min to walk in the store + 3 min to walk back to car + 25 min to drive home = 56 total minutes for one round trip.
5 hours and 36 minutes = (5x60)+36 minutes=336 minutes
336 minutes/56 min per trip = 6 round trips
2/3+2/3=1and 1/3
then you add 266 and 66 which is 332 and after that you add the 1 and 1/3.
that means that the answer is 333 and 1/3.
Answer:
88.46%
Step-by-step explanation:
433 - 383 = 50
50 ÷ 433 = 0.1154
0.1154 x 100 = 11.54%
100% - 11.54% = 88.46%
<u>Check work:</u>
433 x 88.46% = 383
