The answer is 10 quarters because 10 quarters would be $2.50. You would need 3 more nickles to get $2.65. 10 would be 7 more than 3.
        
             
        
        
        
Since adding a constant to a function simply moved the graph upwards by that amount, solve f(x) for any value and see how much the graph given is different from that value of y...the simplest way in this case may be to simply find f(0) which is:
5*2^0=5
Clearly the graph at x=0 is at y=-2  so we can see that k is:
5+k=-2 so
k=-7
        
             
        
        
        
That's for the equation I got from the picture

Answer:
16.7552
Step-by-step explanation:
The Area of a sector of a circle is θ/360 pi r²
so, 
30/360 x 3.142 x 8 x 8
= 16.7551 to four decimal places is
