A solid metal model of a rocket is made up of a cone attached to a cylinder with the same base radius. The cone has a height of 49 cm. The cylinder has a base radius of 18 cm and a height of 192 cm. Given that the mass of the model rocket is 2145 kg, find the density, in kg/m^3, of the metal which the model rocket is made of, giving your answer correct to the nearest whole number. (Density= Mass/Volume) ​

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
