Answer:
848.23 mm²
Step-by-step explanation:
LA = πdh
LA = 3.14159 × 18 mm × 15 mm
LA = 848.23 mm²
Ask: When will (4w-5)(7-w) equal zero?
When 4w-5=0 or 7-w=0
Solve each of the 2 equations above
w = 5/4 , 7
C
y = 1/2x - 7/2
y = 1/2x + b
-3 = 1/2(1) + b
-3 = 1/2 + b
-7/2 = b
since it is exactly in the halfway between
