A quantity with an initial value of 5700 decays exponentially at a rate of 7.5% every 2 days. What is the value of the quantity after 234 hours, to the nearest hundredth?

(Also how do I solve problems like this one?)

i am sure it will be 90 degrees.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
