Step-by-step explanation:
By using Pythagoras theoram,
x²= (6)²+(4)²
optionD
Answer:
2.7 in²
Step-by-step explanation:
Given that ∆BAC ~ is similar to ∆EDF, the ratio of the area of ∆BAC to the area of ∆EDF = the square of the ratio of their corresponding sides.
Thus, let x be the area of ∆EDF
Cross multiply
Area of ∆EDF = 2.7 in²
Add 6 to both sides so you have -2x = 18. If you divide both sides by -2 you will get x = -9
Answer:
Step-by-step explanation:
Let P be the population of the community
So the population of a community increase at a rate proportional to the number of people present at a time
That is
Solve this equation we get
where p is the present population
p₀ is the initial population
If the initial population as doubled in 5 years
that is time t = 5 years
We get
Apply In on both side to get
Substitute in to get
Given that population of a community is 9000 at 3 years
substitute t = 3 in
<h3>Therefore, the initial population is 5937.8</h3>
