14,494
To round off the height value to the nearest thousand we can use the
expanded from to clarity the position of numbers which is:
10, 000 = ten thousand
4, 000 = thousands
400 = hundreds
90 = tens
4 = ones
Here we can notice than four thousand is the value where the nearest
thousands is placed. Hence we can round off the number of 14, 494 into 14, 000.
Notice 0-4 rounding off rules.
        
             
        
        
        
You can calculate them out and check which one is the most accurate
so if one of the choices was 1/3 of 50, then you would do:
1/3 in the calculator (should be 0.333...) times 50
And you can compare it with the EXACT number, which is:
0.25*53=13.25
This way you can test all the options
        
             
        
        
        
Answer:
B) The base graph has been reflected about the y-axis
Step-by-step explanation:
We are given the function,  .
.
Now, as we know,
The new function after transformation is  .
.
<em>As, the function f(x) is changing to g(x) = f(-x)</em> and from the graph below, we see that,
The base function is reflected across y-axis.
Hence, option B is correct.
 
        
             
        
        
        
Hi 
7 = 14.70 
15= X
so :  X =  15*14.70 /7 = 31.5
