250tThe population of Sasquatch in Salt Lake County was modeled by the function P(t)wheret + 25t = 0 represents the year 1803. W

jeyben [28]

Solution

Given the population function to be;

$P(t)=\frac{250t}{t+25}$

When P(t) = 150

$\begin{gathered} \Rightarrow\frac{250t}{t+25}=150 \\ \\ \Rightarrow250t=150(t+25) \\ \\ \Rightarrow250t=150t+3750 \\ \\ \Rightarrow250t-150t=3750 \\ \\ \Rightarrow100t=3750 \\ \\ \Rightarrow t=37.5\approx38 \end{gathered}$

1803 + 38 = 1841.

Find the length of the third side to the nearest tenth.<br> 8<br> 5

brilliants [131]

Answer:

The length of third side is: 6.3

Step-by-step explanation:

Given triangle is a right triangle where

Base = ?

Perpendicular = 5

Hypotenuse = 8

Let x be the base

As it is a right-angled triangle, Pythagoras theorem can be used to find the third side

$Hypotenuse^2 = Base^2 + Perpendicular^2$

Putting the known values

$(8)^2 = x^2 + (5)^2\\x^2 = (8)^2-(5)^2\\x^2 = 64-25\\x^2 = 39\\$

Taking square root on both sides

$\sqrt{x^2} = \sqrt{39}\\x = 6.24499$

Rounding off to the nearest 10th

Base = 6.3

Hence,

The length of third side is: 6.3
