Answer:
x = 0.3333333333
Step-by-step explanation:
Simplifying
42x = 14
Solving
42x = 14
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '42'.
x = 0.3333333333
Simplifying
x = 0.3333333333
Sin²t +cos²t =1
<span> x=2+3 sin t
sin t=(x-2)/3
</span><span>y=1-1/2cos t
y-1= - (cos t)/2
cos t =-(y-1)/(1/2)
</span>(x-2)²/3² + (y-1)²/(1/2)² = 1
Ellipse
3u³ - 4u² - 9u + 12
u²(3u) - u²(4) - 3(3u) + 3(4)
u²(3u - 4) - 3(3u - 4)
(u² - 3)(3u - 4)
F(t)=15000(0.85) ^t => <span>f(t) = $15000(0.85) ^t
Substitute 2 1/3 for t in this equation. This is equivalent to 7/3.
</span> f(7/3) = $15000(0.85)^(7/3)
= $10266.02 (answer)
I think that You add all the ages and then divide by how many people you have so
100:10 = 10 is the mean age I guess?
