A formula is expressed as D= a(2+kt). Express k in terms of D,a, and t.

1 answer:

5 0

This is just rearranging terms, it gets kind of ugly though. Start by dividing both sides by a to get D/a=2+kt, next move the 2 over to the left to get (D/a)-2=kt, finally divide the whole expression by t to get ((D/a)-2)/t=k

Answer:

r = 6

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

PR² = PQ² + QR² , substitute values

(r + 4)² = r² + 8²

r² + 8r + 16 = r² + 64 ( subtract r² from both sides )

8r + 16 = 64 ( subtract 16 from both sides )

8r = 48 ( divide both sides by 8 )

r = 6
