Answer:
see explanation
Step-by-step explanation:
Using the tangent and sine ratios in the right triangle EFG
tan60° =  =
 =  =
 =  ( multiply both sides by EG )
 ( multiply both sides by EG )
EG × tan60° = 28 ( divide both sides by tan60° )
EG =  ≈ 16.2 in ( to the nearest tenth )
 ≈ 16.2 in ( to the nearest tenth )
--------------------------------------------------------------
sin60° =  =
 =  =
 =  ( multiply both sides by EF )
 ( multiply both sides by EF )
EF × sin60° = 28 ( divide both sides by sin60° )
EF =  ≈ 32.3 in ( to the nearest tenth )
 ≈ 32.3 in ( to the nearest tenth )
 
        
             
        
        
        
Answer:
c. -17
Step-by-step explanation:
We have the function f(x) = -2t^2 + 1 and we need to solve for x if f(-3).
Substitute the x in the function with the x in the equation :
f(-3) = -2(-3)^2 + 1
Solve for the answer :
f(-3) = -2(9) + 1
f(-3) = -18 + 1
f(-3) = -17
Therefore, c. -17 is the answer.
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Any digit will work if remainders are allowed.
If you want only whole number results
 9132/12 = 761
9432/12 = 786
9732/12 = 881
