Answer:
Step-by-step explanation:
f(2) = 2^3 - 4(2)^2 = 8 - 4(4) = 8 - 16 = -8
g(-8)= 4(-8) + 5 = -32 + 5 = -27
C is the answer
Answer:
Length of the Area = 50mtrs
Width of the Area = 20mtrs
Step-by-step explanation: Let the x be the length and y be the width of the Area. So we can write x = 2 y + 10 and x y = 1000 or ( 2 y + 10 ) y = 1000 or 2 y 2 + 10 y = 1000 or 2 y 2 + 10 y − 1000 = 0 or y 2 + 5 y − 500 = 0 or y 2 + 25 y − 20 y − 500 = 0 or y ( y + 25 ) − 20 ( y + 25 ) = 0 or ( y + 25 ) ( y − 20 ) = 0 or y + 25 = 0 or y − 20 = 0 or y = − 25 Invalid value contains negative sign or y = 20 So Width of the Area is 20 ----------Ans By plugging the value of y = 20 in the eqn x = 2 y + 10 we get Length of the Area = 2 × 20 + 10 = 50 -------------Ans
Answer:
a
Step-by-step explanation:
For negative correlation, Look for data that is going down
600000 is 1/10 of "x", that means x = 10/10 or a whole, what is "x"?
