Hello there.
<span>A density curve for all the possible ages between 0 years and 100 years is in the shape of a triangle. What is the height of the triangle?
Answer: D</span>
We cannot see the picture
From SOH CAH TOA,
.. cos(22°) = x/11 . . . . . fill in given values for C = A/H
.. 11*cos(22°) = x . . . . . multiply by 11
.. 11*0.927184 = x . . . .use a calculator to find cos(22°)
.. 10.1990 = x . . . . . . . use a calculator to do the multiplication
x ≈ 10.2 . . . . . . . . . . . round to the nearest tenth
Answer:
It will take 5 years for the population to reach 1,944. Option D is correct.
Step-by-step explanation:
Initial population = I = 8
Final population = F = 1944
number of years = x
As given, the population is tripled every year that can be calculated using:
F = I*3^x
By putting values in this equation, we get
1944 = 8*3^x
1944/8 = 3^x
243 = 3^x
3^x = 243
3^x = 3^5
x = 5 bases are same so powers can be simplified.
Therefore, it will take 5 years for the population to reach 1,944. Option D is correct.
