A city that had 7500 thousand people at the beginning of the year 2000 has been decreasing by 3.6% per year. a. What is the 1-ye
storchak [24]

Answer:

Step-by-step explanation:

a) if the population at the beginning of the year 2000 was 7500 people,

The 1-year percent change in the city's population would be

3.6/100 × 7500 = 270

b) The population after 1 year is

7500 - 270 = 7230

The percentage of the previous value of the population to its new value for each year is

7230/7500 × 100 = 96.4%

c) the 1-year growth factor for the population of the city would be

(1 - 0.036)^1 = 0.964

d) the function, g that determines the population of the city (in thousands of people) in terms of the number of years t since the beginning of 2000 would be

g = 7500(1 - 0.036)^t

g = 7500(0.964)^t

Please select the best answer from the choices provided<br><br> T<br> F
bogdanovich [222]

Answer:

T.

Step-by-step explanation:

The ordered pair (-2,-1) can also be represented by (x,y). To check the inequality we can substitute the values into the given inequality.

y>-\sqrt{x+11+1}

-1>-\sqrt{-2+11+1}

-1>-\sqrt{10}

-1>-3.1622

After substituting the values, we then have a clear view that -1 is Greater than -3.1622.

Need help badly don’t have answer to this problem.
NikAS [45]
There are a couple of ways to tackle this one, using the 45-45-90 rule or just using the pythagorean theore, let's use the pythagorean theorem.

the angle at A is 45°, and its opposite side is BC, the angle at C is 45° as well, and its opposite side is AB, well, the angles are the same, thus BC = AB.

hmmm le'ts call hmmm ohh hmmm say z, thus BC = AB = z.

\bf \textit{using the pythagorean theorem}&#10;\\\\&#10;c^2=a^2+b^2 \implies (6\sqrt{2})^2=z^2+z^2&#10;\qquad &#10;\begin{cases}&#10;c=\stackrel{6\sqrt{2}}{hypotenuse}\\&#10;a=\stackrel{z}{adjacent}\\&#10;b=\stackrel{z}{opposite}\\&#10;\end{cases}\\\\\\ 6^2(\sqrt{2})^2=2z^2\implies 36(2)=2z^2\implies \cfrac{36(2)}{2}=z^2\implies 36=z^2&#10;\\\\\\&#10;\sqrt{36}=z\implies 6=z

URGENT! PLEASE help me! Full solutions please, and no nonsense answers.
valentinak56 [21]

Answer:

\frac{1}{3x+52}

Step-by-step explanation:

Given

\frac{\frac{1}{x^2+51x+50} }{\frac{2}{x+50}+\frac{1}{x+1}  }

= \frac{\frac{1}{(x+50)(x+1)} }{\frac{2(x+1)+x+50}{(x+50)(x+1)} }

= \frac{1}{(x+50)(x+1)} × \frac{(x+50)(x+1)}{2x+2+x+50} ← cancel (x + 50)(x + 1) on numerator/denominator

= \frac{1}{3x+52}
