Answer:

The answer would be, A the domain is time and the range is distance.

Step-by-step explanation:

The train is travelling at 100 miles per hour, thus the equation would be d=100t meaning that the distance equals 100 times the amount of time. Now, that means that the input is the amount of time it's been going, and the input is the domain. if the input is the domain,  then the only thing left to be the input (range) is the y value, or, in this case, the d value.

A) The greatest rectangular area will be the area of a square 10 m on each side, 100 m^2.

b) The new dimensions will be 11 m × 11 m.
.. The new area will be (11 m)^2 = 121 m^2.

c) The area was increased by 121 m^2 -100 m^2 = 21 m^2, or 21%.

d) Yes, and no.
.. If you increase the dimensions by 10%, the area will increase by 21%.
.. (40 m)^2 = 1600 m^2
.. (44 m)^2 = 1936 m^2 = 1.21*(1600 m^2), an increase of 21% over the original.

.. If you increase the dimensions by 1 unit, the area will increase by (2x+1) square units, where x is the side of the original. For x≠10, this is not 21 square units.
.. (41 m)^2 = 1681 m^2 = 1600 m^2 +(2*40 +1) m^2 = 1600 m^2 +81 m^2

What is the median of the data?<br><br> 11,16,12,7,23,9,5,5
Stells [14]

Answer:

5,5,7,*9,11,*12,16,23

Step-by-step explanation:

Since, the data has an even amount of numbers once, you put your numbers in order you place your pointer fingers from the 1st to last number & continue to move closer. There is an even amount of numbers so you would have to add the 2 numbers up & then divide them by 2.

9+11=20 divided by 2=10

Write the exact value solution and an approximation for 10^4x=25
Murrr4er [49]

Answer:

exact value: x= \frac{log25}{4}

approximate: x=0.349485

Step-by-step explanation:

Exact Value:

10^{4x} = 25

log (10^{4x})= log 25

4x = log 25

x= \frac{log25}{4}

Approximate:

x= \frac{log25}{4}

x=1.39794/4\\

x=0.349485
