Answer:
509.380
Step-by-step explanation:
According to Pythagoras, 
(19.3)^2 + (11.7)^2 = 509.380
 
        
             
        
        
        
Answer:
c=-5
d=1
Step-by-step explanation:

I'm going to reorder the left-hand side.  Multiplication is commutative.

Since the bases are the same in 
 and the operation is multiplication, I'm going to add the exponents giving me:

So this implies we have two equations to solve:
 and 
So the first equation can be solved by dividing both sides by 4 giving you 
.
The second equation can be solved by subtracting 2 on both sides giving you 
.
 
        
             
        
        
        
Hi. You have to do trial and error with each of the choices to see which of those apply. They are points on the given function y=22x+32 that lie on point (x,y). Just substitute the x-and y values to the function.
a. (10,480) => x = 10, y = 480
     y = 480 = 22(10) + 32
     480 = 252 (does not apply)
b. (5,142) => x = 5, y = 142
     y = 142= 22(5) + 32
     142 = 142 (apply)
c. (8,208) => x = 8, y = 208
     y = 208 = 22(8) + 32
     208 = 208 (apply)
d. (7,154) => x = 7, y = 154
     y = 154 = 22(7) + 32
     154 = 186 (does not apply)
The answer is B and C.
