<span>x^2 - 9x + c
=x^2 - 2(x)(9/2) + (9/2)^2 is a perfect square
Therefore b = (9/2)^2 = 81/4
Ans: 81/4 </span>
Answer:
Number of year in which population will be 180,000 = 6 year (Approx.)
Step-by-step explanation:
Given:
Population in 2007 = 168,979
Rate of increase in population = 1% = 0.01
Future population = 180,000
Find:
Number of year in which population will be 180,000
Computation:
A = P[1+r]ⁿ
Future population = Population in 2007[1+Rate of increase in population]ⁿ
180,000 = 168,979[1+0.01]ⁿ
180,000 = 168,979[1.01]ⁿ
1.06522 = [1.01]ⁿ
n = 6 (Approx.)
Number of year in which population will be 180,000 = 6 year (Approx.)

answerrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
A.
the 2 quantaties are
ricky's distance and greg's distance
it should be total 8 miles
B. ricky distance=ricky rate times ricky time
ricky distance=1.5*3
ricky distance=4.5 miles
ricky distance+greg distance=8
4.5+gdistance=8
minus 4.5 both sides
gdistance=3.5
gdistance=grate time gtime
3.5=2 times time
divide both sides by 2
1.75=time
greg walked 1.75 hour
not sure how to do variable thing and what goes where
ricky walked 4.5 miles
greg walked 1.75 hour and traveled 3.5 miles
Answer:
392
Step-by-step explanation:
7(8) + 3(8)(14)
56 + 24(14)
56 + 336
392
