Answer:

2)

(2x -5) + (x) + (2x - 3) = 32.

5x-8 = 32.

ii) 5x-8=32

5x= 32+8

5x = 40

x= 40/5

x = 8

iii) 2x -5

2 × 8 -5 = 11.

2x-3

2×8-3

16-3 = 13

x =8

sides of the triangle= 8, 11, 13.

Gala2k [10]

Answer:

Annual withdraw= $57,583.68

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $555,000

Interest rate (i)= 0.0825

Number of periods (n)= 20

<u>To calculate the annual withdrawals, we need to use the following formula:</u>

Annual withdraw= (PV*i) / [1 - (1+i)^(-n)]

Annual withdraw= (555,000*0.0825) / [1 - (1.0825^-20)]

Annual withdraw= $57,583.68

Select the figure obtained when rotating the figure about an axis along its largest side, and find the exact surface area of the
Talja [164]

Answer:

Figure obtained - Cylinder

Surface area of the cylinder is 1224π square units.

Step-by-step explanation:

When a rectangle is rotated about an axis along its largest side, a cylinder having radius 17 and height 19 units is formed.

Surface area of the cylinder = 2πr(h + r)

By substituting r = 17 units and h = 19 units in the given formula,

Surface area = 2π(17)(17 + 19)

                     = (34)(36)π

                     = 1224π

Therefore, surface area of the cylinder is 1224π square units.
