Let the rate of stream be x km/hr Then, Speed of downstream = `(25/2) + x` km/hr Speed of upstream = `(25/2) - x` km/hr (12.5 + x) = 3 (12.5 - x ) 12.5 + x = 37.5 - 3x 4x = 25 x = 6.25 km/hr
Given that x = 80, y = -35 and z = -45, Determine the value of [(x³ + y³ + z³)/10³]
If x, y and z are real numbers such that (x-5)2+(y-7)2+(z-9)2= 0 then (x+y+z) is equal to
If sin 28° = 15/17 , then tan 62° = ?
If 3y-3/y=18 then find the value of y² +1/y²
If (Ax + By - Cz) 2 = 4x 2 + 3y 2 + 2z 2 + 4√3xy - 2√6yz - 4√2xz, then find the value of A
If a + b + c = 12 and ab + bc + ca = 50, then find the value of a2 + b2 + c2.
