Answer:

The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Use the Distance Formula to find the distance between (-3, 7) and (8,- 6), rounded to the nearest hundredth.

faust18 [17]

Answer:

17.03 units

Step-by-step explanation:

The distance formula for the distance between two points (x1, y1) and (x2, y2) is ...

d = √((x2 -x1)^2 +(y2 -y1)^2)

For the given points, the distance is ...

d = √((8-(-3))^2 +(-6-7)^2) = √(11^2 +(-13)^2)

d = √(121 +169) = √290

d ≈ 17.03

The distance between the points is about 17.03 units.

A country's population in 1994 was 182 million. In 2002 it was 186 million. Estimate the population in 2004 using the exponentia

iogann1982 [59]

$\bf =ae^{kt}\qquad 
\begin{cases}
1994\impliedby \textit{year 0, starting point}\\
t=0\qquad P=182
\end{cases}\implies 182=ae^{k0}
\\\\\\
182=a\cdot e^0\implies 182=a\cdot 1\implies 182=a
\\\\\\
thus\qquad P=182e^{kt}\\\\
-------------------------------\\\\$

$\bf P=182e^{kt}\qquad 
\begin{cases}
2002\impliedby \textit{8 years later}\\
t=8\qquad P=186
\end{cases}\implies 186=182e^{k8}
\\\\\\
\cfrac{186}{182}=e^{8k}\implies ln\left( \frac{93}{91} \right)=ln(e^{8k})\implies ln\left( \frac{93}{91} \right)=8k
\\\\\\
\cfrac{ln\left( \frac{93}{91} \right)}{8}=k\implies 0.0027\approx k\implies \boxed{P=182e^{0.0027t}}$

what's the population in 2004? well, from 1994 to 2004 is 10 years later, so t = 10

plug that in, to get P for 2004

Does parallel lines meet to form an acute angle??

tia_tia [17]

No bc parallel means they don’t touch, so they wouldn’t meet to form and acute angle
