<span>The easiest way is probably noticing that the plane flies 180 miles farther than the car in the same time. And...the car goes 90 mph slower. If you imagine that they started at the same point...that means that the two trips went on for two hours (2 hours x 90 mph faster = 180 miles farther). </span>

1) What number comes after 234 base 5. Explain<br> 2)What number comes before 210 base 5. Explain
GalinKa [24]

9514 1404 393

Answer:

  1) 240

  2) 211

Step-by-step explanation:

The counting sequence in base 5 is similar to that in base 10, except the digits 5 through 9 are not used. The first few counting numbers are ...

  1, 2, 3, 4, 10, 11, 12, 13, 14, 20, 21, 22, ...

When 1 is added to 4 in the units place, a carry to the fives place is generated and the units digit is returned to zero.

  234₅ +1 = 240₅

  210₅ +1 = 211₅

Graph each absolute value function. State the domain, range, and y-intercept.
SVEN [57.7K]

Answer:

The domain is  (-\infty,\infty) and its range is [3,\infty).

The y-intercept is (0,3).

Step-by-step explanation:

Consider the parent function y=|x|. Its domain is x\in (-\infty,\infty) and its range is y\in [0,\infty).

The graph of the function y=|x|+3 is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the  domain and will change the range of the function, thus the domain is  (-\infty,\infty) and its range is [3,\infty).

To find th y-intercept you have to find y at x=0:

y=|0|+3=3.

Hence, the y-intercept is (0,3).
