You can model the population of a certain city between the years 1965 and 1995 by the radical function P(x)= 75,000 cubed root o

f (x-1940) . Using this model, in what year was the population of that city 245,000?

<span>P(x)= 75,000*(x-1940)^(1/3)
then the P = 245000 means

245000 = </span>75,000*(x-1940)^(1/3)
(245000/75000)^3 + 1940 = X
X ≈ 1974

Find derivative: f(u) = arctan(u/(1+u)

VikaD [51]

F ` ( x ) =
$\frac{1}{1+ \frac{u ^{2} }{(1+u) ^{2} } } * ( \frac{u}{1+u})`= \\ = \frac{1}{ \frac{(1+u) ^{2}+ u^{2} }{(1+u) ^{2} } } * \frac{(u)`(1+u)-(1+u)` u}{(1+u) ^{2} } = \\ = \frac{(1+u) ^{2} }{(1+u) ^{2}+u ^{2} } * \frac{1+u-u}{(1+u) ^{2} } = \\ = \frac{1}{1+2u+2u ^{2} }$

How do you calculate a score

dem82 [27]

Answer:

You divide what you got by how many questions there are. For example, if you got 18/20, you'd divide 18 by 20 with a calculator. Which would be 0.9, then you move the decimal over 2 times making it 90, so you got 90%

Please help me on math and explain how to get the answer.

Lynna [10]

Answer:

x = 128

Step-by-step explanation:

ill name the empty angle y for clarification

y + 38 + 90 = 180

y + 128 = 180

y = 52

180 - y = x

180 - 52 = x

x = 128
