Tangent line of f(x) = sec x @ (pi/3, 2)

Dmitry_Shevchenko [17]

The derivitive of sec(x) is sec(x)tan(x)

find the slope at pi/3

sec(pi/3)=2
tan(pi/3)=√3

sec(x)tan(x) at x=pi/3 is 2√3

for slope=m and a point is (x1,y1)
the equation is
y-y1=m(x-x1)
slope=2√3
point=(pi/3,2)

equation is
y-2=2√3(x-pi/3)

Find the midpoint of the line segment<br> with endpoints (-4, 16) and (6, -10).

Alenkasestr [34]

Answer:

Step-by-step explanation:

<h3>What is a midpoint?</h3>

Midpoint a point equidistant from the ends of a line or the extremities of a figure.

To find the midpoint of the line segment with endpoint, use the midpoint formula.

<u>Midpoint formula:</u>

$\Rightarrow: \sf{\dfrac{x_2+x_1}{2}, \dfrac{y_2+y_1}{2} }}}$

y2=(-10)

y1=16

x2=6

x1=(-4)

<u>Rewrite the problem down.</u>

$\sf{\left(\dfrac{6-4}{2},\:\dfrac{-10+16}{2}\right)}$

<u>Solve.</u>

6-4=2

2/2=1

-10+16=6

6/2=3

Therefore, the correct answer is B (1,3).

I hope this helps, let me know if you have any questions.
