Synovial joints have these features: an articular capsule, a joint cavity containing synovial fluid, articular cartilage, ligaments, blood vessels and nerves. a. true
b. false

True.

Explanation:

Synovial joints are joint that join bones with fluid filled cartilage cavity called synovial cavity, this have the space that contain the synovial fluid. The joint capsule is made up of outer layer, articular capsule that keep the bone together, and inner layer, the synovial membrane that seals the synovial fluid. The bones of synovial joint are covered with hyaline cartilage layer which line the epipysises of the joint end bone. The articular cartilage help to reduce shock and ease movement. The types of synovial joints are pivot, hinge, saddle,condyloid, plane, ball and socket joints. The synovial joints have ligaments and blood vessels.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
