Yuri [45]

Step-by-step explanation:

Distance between Train 1 and Train 2=95 miles

Avg speed Train 1 = 45mph, avg speed Train 2=60mph

If both trains leave at the same time and travel toward each other but on parallel tracks, in how much time will their engines be opposite each other?

:

Let t = travel time (in hrs) until they are opposite each other

:

Like the hint said, when this happens the total distance traveled by both trains will be 95 mi.

:

write a distance equation from this fact: Dist = speed * time

;

Train 1 dist + train 2 dist = 95 mi

45t + 60t = 95

:

105t = 95

t = 95%2F105

t = .90476 hrs

or

.90476 * 60 = 54.3 min

:

:

Check solution by finding the total of the distances the two train travel

45(.90476) + 60(.90476) =

40.7 + 54.3 = 95 mi

If f(x) = −2[x]+ 8, what is f(−1.8)?<br><br><br> 4<br><br> 6<br><br> 10<br><br> 12
Genrish500 [490]

Functions whose graphs resemble sets of stairsteps are known as step functions. The most famous of the step functions is the greatest integer function, which is denoted by:


f(x)=[x]


which graph is shown in the Figure below. As you can see from the graph:


if \ x=-1.8 \ then \ f(-1.8)=[-1.8]=-2


Therefore:


f(-1.8)=-2[-1.8]+8=-2(-2)+8=\boxed{12}


So the right answer is 12

In the year 2000, The U.S. Budgeted $25,003 million for Natural Resources and Environment. In 2014, they budgeted $40,156 millio
stiks02 [169]

Using it's concepts, we have that:

  • The absolute change was of $15,153 million.
  • The relative change was of 60.60%.

<h3>What is the absolute change of two values?</h3>

The absolute change between two values is given by the absolute value of the difference between two values.

In this problem, the values are of $40,156 million, which is the final value, and $25,003 million, which is the initial value, hence the absolute change is:

A = 40,156 - 25,003 = $15,153 million.

<h3>What is the relative change?</h3>

The relative change is the absolute change multiplied by 100% and divided by the initial value, hence:

(15,153/25,003) x 100% = 60.60%.
