You are hiking up a mountain peak. You begin hiking at a trailhead whose elevation is about 9400 feet. The trail ends near the summit at 14,255 feet. The horizontal distance between these two points is about 17,625 feet. Estimate the angle of elevation from the trailhead to the summit.
Answers
Answer:
Estimate angle of elevation = 15.4°
Step-by-step explanation:
Given:
Start elevation = 9,400 ft
Ends near the summit = 14,255 ft
horizontal distance = 17,625 ft
Find:
Estimate angle of elevation.
Computation:
⇒ Total elevation distance = Ends near the summit - Start elevation
⇒ Total elevation distance = 14,255 - 9,400
⇒ Total elevation distance = 4,855 ft
⇒ Tan A = 4,855 / 17,625
⇒ Tan A = 0.2754
⇒ Tan A = 15.4°
Estimate angle of elevation = 15.4°

It will take the construction company 48 hours to remove 36 tons of dirt from the site.The construction company can remove \( \frac{3}{4} \) tons of dirt from the site each hour.
To find out how long it will take them to remove 36 tons of dirt, we can set up a proportion
Given:Amount of dirt removed in one hour =
Total amount of dirt to be removed = 36 tons
Let t represent the time in hours it will take to remove 36 tons of dirt. Plugging in the values:
Solving for hours
So, it will take the construction company 48 hours to remove 36 tons of dirt from the site.

Answer: x = 0
Explanation
The idea is to replace h(x) with 3. Then we isolate x. Follow PEMDAS in reverse to get x by itself.
Here are the steps:
h(x) = -5x+3
3 = -5x+3
-5x+3 = 3
-5x = 3-3
-5x = 0
x = 0/(-5)
x = 0
As a check,
h(x) = -5x+3
h(0) = -5*0 + 3
h(0) = 0 + 3
h(0) = 3
Therefore, the input x = 0 in the domain leads to the output h(x) = 3 in the range. We have confirmed the answer x = 0
Another way to confirm the answer is to use a graphing tool like GeoGebra or Desmos.
