  1. f(x) =2x-6

             y=2(-2)-6

           = <u>-10</u>

2) y=2[1]-6

     = <u>-4</u>

Answer:

the range is : (-10,-4,4,10)

Step-by-step explanation:

calculate :

f(-2) = 2(-2) -6 = -10

f(1) = 2(1) -6 = -4

f(5) = 2(5) -6 = 4

f(8) = 2(8) -6 = 10

the range is : (-10,-4,4,10)

Water flows from a tank with a rectangular base measuring 80cm by 70cm into another tank with a squarebase of side 60cm. If the
defon

Answer:

70cm

Step-by-step explanation:

,

Since, both of the tank posses the same quantity of water then there volume is the same thing

For rectangular base

Volume= (Lenght × breadth × hheight)

If we substitute values

Lenght= 80 cm

Breadth= 70 cm

height= 45 cm

Volume= 80cm × 70cm × 45cm

Volume= 252000cm^3

For square base

Volume= (side)^2 × height

side =60cm.

But volume of square base= volume of

rectangular base

252000cm^3= 60^2 × height

Height= (252000cm^3)/(60^2 )

Height= 70 cm

Hence, the second tank is 70 cm deep
