If f(x)=20, what does x equal?

Mathematics

Snowcat [4.5K]3 years ago

Answer:

20

Step-by-step explanation:

X=20 because f (20) would also be 20. Since we don't know the value behind 20, we would suppose x is the value. The original equation is now f(x)=x. If we do f(20)=x we would get that (since x is being substituted) f(20)=20.

You are traveling at 75 miles per hour on a straight stretch of highway in Nevada. It is noon now. When will you arrive at the n
Levart [38]
Right now it is noon..... you are traveling 75 miles per hour meaning you'll move 75 miles... every hour. so you're 120 miles away so now we need to figure out the time.... to do this we already know 1 hour is 75 miles so now you can subtract one hour 120-75= 45 so 75 per hour, what would 45 be?..... so we can set up a fraction to figure out how long it takes to travel one minute.... so 60/75(the 60 is for minutes in an hour). which is .8 of a second to travel one mile so.... now you can multiply to check your work. .8*75=60 mins.... so now multiply.8*45(miles left)=36 so you'd get there at 1:36 it would take an hour and 36 mins to get to your destination going 75mph

Find the angle of elevation of the sun when a 12.5 meter tall telephone pole casts an 18 meter
MAVERICK [17]
To answer this problem, you should know the formula that we will be using and this would be:
Angle of elevation = arc tan( (vertical height)/(length of the shadow)).

Plugging in the values in the formula. Here, this angle is:

arc tan (12.5/18) = <span>34.78 degrees</span>

The answer would be approximately 34.78 degrees
