Identify the domain and range of each graph

vova2212 [387]

Answer:

Step-by-step explanation:

You didn't mark your graph but I'm assuming the point is (1,2)

You notice how the function stops at the point? x and y can not be above that point because there is no line above it.

The domain of the function means what can x possibly be.

The maximum value of x in this function is 1 because that's the x value of the point where the function ended. This means x can at most be one or x≤1. So the domain is x≤1.

The range of the function means what can y possibly be.

The maximum value of y in this function is 2 because that's the y value of the point where the function ended. This means y can at most be two or y≤2. So the range is y≤2.

Two trains leave stations 546 miles apart at the same time and travel toward each other. One train travels at 95 miles per hour

Ira Lisetskai [31]

<u>Answer:</u>

It will take 2 hours 36 minutes for the two trains to meet.

<u>Step-by-step explanation:</u>

The distance between the two trains is decreasing by $95+115= 210$ miles per hour, which can be written as $\frac{210 miles}{1 hour}$ .

So at this rate, the distance between the trains will be reduced to zero in:

$\frac{546 miles}{\frac{210 miles}{1 hour} } = 476 miles * \frac{1 hour}{210 miles}$

$= \frac{546}{210} = 2.6 hours$

Changing 2.6 hours to hours and minutes:

$2 hours + 0.6 hours = 2 hours + (0.6 * 60) = 2 hours + 36 minutes$

Therefore, it will take 2 hours 36 minutes for the two trains to meet.

Fill in the missing values to make the equations true.(a) log, 7 + log2 5 = log2음Х8(b) log, 8 - log, I = log,7(c) log, 4 = 2log,

Zielflug [23.3K]

(a).

Simplify the expression to obtain the value at missing place.

$\begin{gathered} \log _27+\log _25=\log _2(7\cdot5) \\ =\log _235 \end{gathered}$

Blank space: 35

(B).

Simplify the expression to obtain the value of missing place.

$\log _9(\frac{8}{7})=\log _98-\log _97$

Blank space : 7

(C)

Simplify the expression to obtain the value at missing place.

$\begin{gathered} \log _74=\log _7(2)^2 \\ =2\log _72 \end{gathered}$

Blank space: 2
