Answer:

a. y = 250 (0.4)^x

b. 0.066

Step-by-step explanation:

The equation can be modeled as a geometric sequence, where the first term is 100 and the common ratio is 0.4.

y = 100 (0.4)^(x − 1)

This can also be simplified to:

y = 250 (0.4)^x

When x = 9:

y = 250 (0.4)^9

y = 0.066

Given MO is perpendicular to NP and NO is congruent to PO prove MN is congruent to MP
VladimirAG [237]
Lets imagine the shape 
M
  /\
  / | \
  / | \
  / | \
  P /___ |___\ N
  O
 Now in If we take â†MOP and â†MON
 As MO ⊥ NP so â MON=â MOP
 NO=NP (given)
 And MO is a common side 
 so by side angle side rule of congruency 
 â†MOP and â†MON are congruent
 so MP is congruent to MN
