Arrange the functions in ascending order, starting with the function that eventually has the least value and ending with the fun
nataly862011 [7]

Answer:

Following are the responses to the given question:

Step-by-step explanation:

When x is squared, it's going to be bigger by the conclusion because the larger the faster. x^2 + 4consistently exceeds 4 x^2, regardless of the price of X.

5x+3 is always 3 more so than 5x.

In particular, this can be classified according to its pathways (5x

 5x\\\\5x + 3\\\\7x\\\\8x + 3\\\\x^2\\\\x^2 + 4

So can alternatively just say "eventually," which means because when x really is big, you need to find one another's values. Then just select x=100, then plug it into every single other. To confirm this order:

5(100) = 500\\\\5(100) + 3 = 503\\\\7(100) = 700\\\\8(100) + 3 = 803\\\\(100)^2 = 10,000\\\\(100)^2 + 4 = 10,004\\\\

So, the ascending order must be the right order!

Please tell me how to do this, I'll mark brainliest if you do
Arada [10]

The bottom line is a straight line that is equal to 180 degrees.

The three angles above it all need to add together to equal 180.

One angle is given as 20, so the other two need to add together to equal 160 ( 180-20 = 160)

Those two angles form the angle ACE so the answer would be 160 degrees,

Answer 160 degrees.

A car is 200 km from its destination after an hour and 80 km from its destination after 3 hour
Pani-rosa [81]

200 - 80 is equal to 120. So the car traveled 120 km in 3 hours. It travels at an average of 120/3 = 40 km/hr, and will reach its destination in 2 hours.
