The incline of a roller coaster is 2 times as long as its elevation, and the horizontal length of the roller coaster is 11 m mor

Gelneren [198K]

Let
x-------> t<span>he horizontal length of the roller coaster
y------> </span>the elevation of the roller coaster
c------> t<span>he incline of a roller coaster
</span>
we know that
applying the Pythagoras theorem
c²=x²+y²-----> equation 1
c=2y-----> equation 2
x=11+y----> equation 3

substitute equation 2 and equation 3 in equation 1
[2y]²=(11+y)²+y²
4y²=11²+22y+y²+y²
2y²-22y-121=0

using a graph tool-----> to resolve the second order equation
see the attached figure

the solution is
y=15.026 m

c=2*y-----> c=2*15.026----> c=30.052 m

the answer is
30.05 m

MAVERICK [17]

Answer:

566,880

Step-by-step explanation:

First you have to understand what the problem is asking you. It wants you to find the difference between working for 40 years with a master's degree and 40 years with a bachelor's degree.

Next you need to do the math. You can use a calculator since these are pretty large numbers. Enter in the following to find how much you make working 40 years with a bachelor's degree: 68,103 * 40 Once you have calculated that, you should get 2,724,120. Now you need to find how much you earn working 40 years with a master's degree. Enter the following: 82,275 * 40 You should get 3,291,000.

Finally you need to find the difference. Type into your calculator the following: 3,291,000 - 2,724,120 You should end up with 566,880.

Hope this helps!
