Atmospheric pressure decreases by about 11.8% for every 1000 meters you climb. The pressure at sea level is 1013 millibars (a un

erica [24]

At sea level, the pressure is 1013, that's when the altitude is at 0, sea level, let's see

$\bf \textit{Periodic Exponential Decay}\\\\
A=I(1 - r)^{\frac{t}{p}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &1013\\
I=\textit{initial amount}\\
r=rate\to 11.8\%\to \frac{11.8}{100}\to &0.118\\
t=\textit{meters climbed}\to &0\\
p=period\to &1000
\end{cases}
\\\\\\
1013=I(1-0.118)^{\frac{0}{1000}}\implies 1013=I\cdot 1\implies 1013=I$

so, the inital amount is 1013, when t = 0,

$\bf \textit{Periodic Exponential Decay}\\\\
A=I(1- r)^{\frac{t}{p}}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &1013\\
r=rate\to 11.8\%\to \frac{11.8}{100}\to &0.118\\
t=\textit{meters climbed}\to &t\\
p=period\to &1000
\end{cases}
\\\\\\
A=1013(1-0.118)^{\frac{t}{1000}}\implies A=1013(0.882)^{\frac{t}{1000}}$

now, to check the atmospheric pressure at 4000, simply set t = 4000, to get A.

Triangle ABC is isosceles.

NARA [144]

we know that

An isosceles triangle is a triangle with two equal sides and two equal angles

in this problem we have

AC=AB

∠B=∠C

therefore

the answer is

It is equal to the measure of angle C

A baseball player hits a ball toward the outfield. The height h of the ball in feet is modeled by h(t) = -16t2 + 22t + 3, where

$h(t)=-16t^2+22t+3\\(0)=-(8t+1)(2t-3)\\8t+1=0:2t-3=0\\8t=-1:2t=3\\t=\frac{-1}{8}:t=\frac{3}{2}$

Add the two expressions 3.8b - 7 and 2.9b + 9 enter your answer in simplified form

worty [1.4K]

Answer:

The answer would be 6.7b + 2

Step-by-step explanation:

In order to simplify this, simply add the like terms together.

3.8b + 2.9b = 6.7b

-7 + 9 = 2

Now just put those two together

6.7b + 2
