Answer:
x = 12
Step-by-step explanation:
The midsegment VY is half the sum of the parallel bases , that is
VY =
, then
3x + 18 =
(x + 96) ← multiply both sides by 2 to clear the fraction
6x + 36 = x + 96 ( subtract x from both sides )
5x + 36 = 96 ( subtract 36 from both sides )
5x = 60 ( divide both sides by 5 )
x = 12
Answer:

Step-by-step explanation:
The population of a community is known to increase at a rate proportional to the number of people present at time t.
This means that the population growth is modeled by the following differential equation:

Which has the following solution:

In which P(t) is the population after t years, P(0) is the initial population and r is the growth rate.
The population has doubled in 10 years
This means that
. We use this to find r.







So the equation that will estimate the population of the community in t years is:

9. i dissagree because 0.70 and 0.7 is the same thing
10. is 1.45
11. is 0.37
Answer:
B - 108
Step-by-step explanation:
A regular pentagon is 540 degrees. Divide 540 by 5 (since there are five sides) which equals 108 degrees.
