We know that 
1 mile----------------> 1609.34 meters
26 miles---------------> X
X=26*1609.34=41842.84 m

I apply a rule of three to know the time

if 100 m---------------9.96 sec
41842.84 m----------> x
x=41842.84*9.96/100=4167.5468 sec

to get minutes I divide it by 60---------> 4167.5468/60=69.459113 minutes

to get hours I divide it by 60----------> 69.459113/60=1.1576518 hours

1.1576518= 1 hour 9 minutes 27.55 sec

the answer is 1 hour 9 minutes 27.55 sec------->(4167.5468 sec)

Hello,

\lim_{x \to 0}\dfrac{ \sqrt{x+25}-5}{x}\\\\

=\lim_{x \to 0}\dfrac{(\sqrt{x+25}-5)*(\sqrt{x+25}+5)}{x*(\sqrt{x+25}+5)}\\\\

=\lim_{x \to 0}\dfrac{x+25-25)}{x*(\sqrt{x+25}+5)}\\\\


=\dfrac{1}{10}

Find the slope of a line if the points (2,-1) and (5,3) are on the line
Romashka [77]

Answer:

\huge{ \boxed{ \sf{ \frac{4}{3} }}}

Step-by-step explanation:

\star{ \sf{ \: Let \: the \: points \: be \: A \: and \: B}}

\star{ \sf{ \: Let \: a(2,-1)  \: be \: (x1 \:, y1) \: and \: b (5,3)  \: be \: (x2 \:, y2)}}

\underline{ \sf{Finding \: the \: slope \: of \: the \: line}}

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

\mapsto{ \sf{Slope =  \frac{3 - ( - 1)}{5 - 2} }}

\mapsto{ \sf{Slope =  \frac{3 + 1}{5 - 2}}}

\mapsto{ \sf{Slope =  \frac{4}{3} }}

Hope I helped!

Best regards! :D
