Substituting the data points into the model:
f(x)= -x2 + 2x -3
f(-2)=-11
f(0)=-3
f(1)=-2
f(3)=-6
f(5)=-18
So A is the right ans.
 
        
                    
             
        
        
        
Answer:
About 30.98386677 ft above the water.
Step-by-step explanation:
Use pythagorean theorem, a^2+b^2=c^2.
So when you plug in the numbers it would be x^2+22^2=38^2. Move 22^2 to the right side giving you x^2=38^2-22^2. Then subtract and take the square root of x^2.
 
        
             
        
        
        
Answer:
180 square feet
Step-by-step explanation:
A rug that is geometrically similar to her room floor is one that has the same size as her room floor.
The floor has dimensions 12 feet by 15 feet.
The area of the floor and hence, the rug is:
A = 12 * 15 = 180 square feet
She should buy a rug that is 180 square feet
 
        
             
        
        
        
The equation: n - 4 = -15
Now let's solve our equation for n. 
n - 4 = -15
Add 4 to both sides.
n = -11
 
        
             
        
        
        
The Correct answer is C. -14 + (-10) = -24 and 2 + (-28) = -26. When negative numbers are in play, the lower negative number is higher in value. So when solved -24 > -26
