Step-by-step explanation:
First 
since its follow the pattern Intercept Max... Intercept Min...
Its a positive sine graph 
Asin(B(x-0))<0.25 
A=1 
B=2π/period 
period From the graph = 2π
B=2π/2π
B=1 
Sin(x)<0.25
I'd go with C.

Answer:
 the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.

This is an incomplete problem. The missing information is 
Each bulleted statement describes how the amount of income tax is determined for
yearly income in different ranges. 
1) Yearly incomes of $8,925 or less are taxed at a flat rate of 10%. 
2) For yearly incomes from $8,926 to $36,250, the first $8,925 is taxed at 10%
and any income beyond $8,925 is taxed at 15%. 
3) For yearly income greater than $36,250, the first $8,925 is taxed at 10%, the
next $27,325 is taxed at 15%, and any income beyond $36,250 is taxed at
25%
The taxable income of Mr. Vance corresponds to number 2.
⇒ 8,925 * 10% = 892.50
⇒ 35,675 - 8,925 = 26,750 * 15% = 4,012.50
Total tax = 892.50 + 4,012.50 = 4,905
        
             
        
        
        
First, we are going to find the radius of the yaw mark. To do that we are going to use the formula: 

where 

 is the length of the chord 

 is the middle ordinate 
We know from our problem that the tires leave a yaw mark with a 52 foot chord and a middle ornate of 6 feet, so 

 and 

. Lets replace those values in our formula:




Next, to find the minimum speed, we are going to use the formula: 

where

 is <span>drag factor
</span>

 is the radius 
We know form our problem that the drag factor is 0.2, so 

. We also know from our previous calculation that the radius is 

, so 

. Lets replace those values in our formula:



 mph
We can conclude that Mrs. Beluga's minimum speed before she applied the brakes was 
13.34 miles per hour.
