Answer:

x ∈ {5, 7}
(5,7)

Step-by-step explanation:

The graph shows the function value is zero for x=5 and x=7. These are the elements of the solution set.

x ∈ {5, 7}

The graph is below the x-axis between these points, so that is the region where f(x) < 0

5 < x < 7 . . . . . for f(x) < 0

In interval notation: (5, 7).

Find the surface area and volume of a cylinder with a diameter equal

dangina [55]

Answer:

Volume = 1539.38 cm³

Surface Area = 747.7 cm²

Step-by-step explanation:

Volume = πr² h

V = π(7)²(10)

V = π(49)(10)

V = 490π

V = 1539.38 cm³

Surface Area = 2πrh + 2πr²

SA = 2π(7)(10) + 2π(7)²

SA = 2π(70) + 2π(49)

SA = 140π + 98π

SA = 238π

SA = 747.7 cm²
