Y=(x-h)^2+k where (h,k) is the vertex
So, equation of new parabola is:
y=(x+1)^2+7
        
             
        
        
        
Answer:
DONE
Step-by-step explanation:
HE CHARGES $145 PER HOUR
1 HOUR=$145
2 HOUR= $145*2= $290
3 HOUR= $145*3= $435
4 HOUR= $145*4=$580
 
        
             
        
        
        
The answer is c.
The discount is 20% off, right? What's 20% of 35? To do that, you need to do the problem 35*.20, because .20 is equivalent to 20%. Remember how it is 20% off? That means subtract here. When you do 35*.20, you'll get 7. Now, subtract 7 from 35. 35-7=28, and your answer is in money; $28.00. :)
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
First, let's check side lengths.
Using the Pythagorean theorem we can find the length of the other side of the rectangle.
a^2 + b^2 = c^2
4.2^2 + b^2 = 8.6^2
b^2 = 56.32
b = 7.5
The other side of the rectangle measures 7.5 cm, so now we know that 4.2 cm is indeed the shorter side of the rectangle.
For the angle in question, the 4.2 cm side is the adjacent leg.
The diagonal of 8.6 cm is the hypotenuse.
The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.

Answer:
   ? = 15a^2
Step-by-step explanation:
We assume you want
   (5a)/(8ab) = (?)/(24a^2·b)
Multiplying by 24a^2·b, we get ...
   (5a)/(8ab)·(24a^2·b) = ? = 15a^2
