Answer:

The current population (in 2005) is 4000 because it is the constant. The slope tells us how many people are added to the population, so 70 per year. For ex. 2008 (2008- 2005 = 3=> 3 x 70 = 210 => 210 + 4000 = 4210).

Help, please, what is the answer??
Mrac [35]

Answer:

18.0

Step-by-step explanation:

The three lines form a right triangle where 10 and 15 are the two legs of the triangle. You can use the pythagorean theorem to solve for the length of x.

x = \sqrt{15^{2} + 10^{2}  }

x = 18.028 (approximately 18)

What is the slope of the line passing through the points (0,-5) and (4,2)?
alukav5142 [94]

Answer:

\huge{ \boxed{ \tt{ \frac{ 7}{4} }}}

Step-by-step explanation:

\text{Let \: the \: points \: be \: A \: and \: B}

\sf{A \:( \: 0 \:,  - 5 \: )  \longrightarrow{ \: (x1 \:, y1)}}

\sf{B(4 \:, 2) \:  \longrightarrow{ \:( x2 \:, y2)}}

\underline{ \text{Finding \: the \: slope} }:

\boxed{ \sf{Slope =  \frac{y2 - y1}{x2 - x1}}}

\sf{➳ \: Slope =  \frac{2 - ( - 5)}{4  - 0}}

\sf{➳ \: Slope =  \frac{ 2 + 5}{4} }

\sf{➳ \: Slope =  \frac{7}{4} }

*100 points* What is the value of x in these polygons?
Effectus [21]

Answer and Step-by-step explanation:

Greetings!

Let's~answer~your~question!

Since~ we~ know~ that ~these ~two~ are~ similar, ~it ~is ~also~ given ~that~ corresponding\\ parts ~of ~the~ triangle~ are ~proportional.~ In ~result,~ you~ can~ set~ the~ proportions~\\something~ like~ this:

\frac{16}{32}= \frac{12}{24}

Now,~from~ here, you~ can ~figure~ out~ that~ the~ ratio~ of ~the ~larger ~triangle~ to ~the \\~smaller~ triangle~ is ~.75:1

You~can~ then~ apply~ this~ to~ the~ side ~of ~x-1 ~and ~set~ up ~the~ equation.

.75(x-1)=6

Now,~solving~ the~ equation,~ you~ get~ x=9.~ Substitute~ that~ into~ x-1~ and~ you\\ get~ 8 ~as ~that~ side~ length.~ To~ check, compare:

\frac{8}{6}=\frac{32}{24}

Thus,~the~value~of~x~is=9.

Hope~my~answer~helps~you!~Have~a~blessed~day~ahead!
