Answer:
D. -1/64
Step-by-step explanation:
F(x) = (1/4)^-3
This is 1/4 to the power of -3
= -(1/4)*(-1/4)*(-1/4)
= -(1*1*1)/(4*4*4)
= -1/64
Another way to calculate this is (-1/4)*(-1/4)*(-1/4). This is the same as (-1/4)³
When solved out the solution = -1/64
Therefore the correct answer to this question is the last option, which is d.
Thank you.
Answer:
(0,0)
Step-by-step explanation:
(x,y)= ( (x1 +x2)/2 , (y1+ y2)/2 )
= ( -7+7/2 , 7-7/2)
= (0/2 , 0/2)
= (0,0)
Therefore, the midpoint is at interval (0,0)
Answer:
(E) 450
Step-by-step explanation:
Let x represent the number of gallons of solution X that must be added to the mix. Then the amount of sugar in the mix is ...
0.20x +0.40·150 = 0.25(150 +x)
0.20x +60 = 37.5 +0.25x . . . eliminate parentheses
22.5 + 0.20x = 0.25x . . . . . . subtract 37.5
22.5 = 0.05x . . . . . . . . . . . . . subtract 0.20x
450 = x . . . . . . . . . . . . . . . . . . multiply by 20
450 gallons of solution X must be added to make a 25% sugar solution.
