Edward started his hike at an elevation of 115 feet below sea level. Throughout the hike he ascended 3,200 feet and then descended 676 feet. How much did his elevation change?
115+676=791
3200-791= 2409
his elevation changed by 2409 ft
Answer: 7.5 miles
Step-by-step explanation:
think of it as a triangle; the bold line is the hypotenuse, or x.
8 |\ x
|_\ it's not a good triangle but you get the point
6
and then get out pythagorean theorem: a^2+b^2=c^2
put the numbers in: 8^2 + 6^2 = x^2
do some math:
64+36=x^2
100=x^2 (and then find square root)
10=x
<u>BUT</u>, it said each unit was 3/4 of a mile, so we must multiply 10 by 3/4 to get the actual distance, which is 7.5
I can't see the next photo but I'm assuming that's what you're asking
-2 (t+4)= -2 (t)+-2 (4)= -2t-8
