9) yes it is similar : it does not have to be congruent
10) scale factor: 2 (inside) :3 (outside)
11) ratio: 16 (inside) : 24 (outside)
12) Yes they are similar
hope this helps
Answer:
f(x) = 86(1.01)^7x; They grow at approximately the rate of 1% per day.
Step-by-step explanation
86 is the number of weeds at the starting point of the question.
8/7% each day, 7 being the total number of days in the week, the weekly growth 8%: 1 day is 8/7% growth or 1.14% rounded up to 1%
In the original equation the 8% growth was represented by 1.08
Substituting the weekly rate of 8% with the daily rate of 1%, or 1.08 with 1.01 the new function is:
f(x) = 86(1.01)^7x

Answer:
No, quadrilaterals ABCD and EFGH are not similar because their corresponding segments are not proportional
Step-by-step explanation:
Corresponding sides have the same slope, so corresponding angles are congruent.
Side AB is 1/2 the length of side EF; side BC is equal to the length of FG, so corresponding sides are not proportional.
The two quadrilaterals are not similar because their corresponding segments are not proportional (last choice).
