Answer:25.12

Step-by-step explanation:

so the diameter of the circle is 16 and to find the circumference you need the radius so you will divide 16 by 2 which is 8 then you times 8 by pi which is 3.14. 3.14 times 8 = 25.12.

Finding an Equation of a Tangent Line In Exercise, find an equation of the tangent line to the graph of the function at the give

solmaris [256]

Answer:

$x=5y$

Step-by-step explanation:

We are given that

$g(x)=log_{10}(2x)$

Point(5,1)

$g(x)=\frac{ln(2x)}{log10}$

By using property

$log_x y=\frac{lny}{lnx}$

We have to find the equation of tangent line to the given graph.

Differentiate w.r.t x

$g'(x)=\frac{1}{2xlog 10}\times 2$

By using the formula

$\frac{d(lnx)}{dx}=\frac{1}{x}$

$\frac{dy}{dx}=\frac{1}{xlog 10}$

We know that Log 10=1

$m=g'(x)=\frac{1}{x}$

Substitute x=5

$m=\frac{1}{5}$

Point-slope form

$y-y_1=m(x-x_1)$

By using this formula

$y-1=\frac{1}{5}(x-5)$

$5y-5=x-5$

$x-5y=-5+5=0$

$x=5y$

Hence, the equation of tangent line to the graph

$x=5y$

Which formula can be used to describe the sequence below? 29, 9, 3, 1, 1/3,.....

Maksim231197 [3]

Answer:

Answer is $3^{4-n}$

Step-by-step explanation:

It is 29 in place of 27 . and Its a geometric series with first term 27 and common ratio $\frac{1}{3}$

and general formula for given sequence is given by $a (r)^{n-1}$

so plugging the value of a and r ,we get

$27 ([tex]\frac{1}{3}$ )^{n-1}[/tex]

$3^3(\frac{1}{3} )}^{n-1}$

$3^{4-n}$
