Answer:
B or 7
Step-by-step explanation:
Start by doing what is in the brackets (10 + 25) = 35
Now worry about 35 / z
z = 5 Given
35 / 5 = 7
Answer: 7 which is B
Answer: No, because 7^2 + 10^2 is > 12^2
Step-by-step explanation: 7^2 +10^2= 49 + 100= 149 149 
144
Answer:
what is the question be more specific
C can be found using pythagoras theorem. c2=a2+b2. Now, b is not given, but we know that cos(theta)=b/c=>b=c*cos(theta). Substituting b in the above relation, c2=a2+c2(cos(theta))^2=>c2=a2/(1-cos((theta))^2). c is the squareroot of c2. Hence c=sqrt(2/(1-cos((theta))^2))
Answer:
{- 3, - 2, 0, 2 }
Step-by-step explanation:
The range is the y- coordinates of the points
(- 4, - 3 ) , (- 1, - 2 ) , (- 2, 0 ) , (0, 2 )
The y- coordinates are - 3, - 2, 0, 2
Then the range is { - 3, - 2, 0, 2 }
