190 = 200^b, make b the subject

1 answer:

MArishka [77]2 years ago

3 0

Answer:

b = $\frac{ln190}{ln200}$

Step-by-step explanation:

Using the rule of logarithms

log $x^{n}$ ⇔ nlogx

Given

190 = $200^{b}$ ( take the natural log ln of both sides )

ln190 = ln $200^{b}$ = bln200 ( divide both sides by ln200 )

$\frac{ln190}{ln200}$ = b

Find the length of the arc.

Arte-miy333 [17]

radius=r=7in
Angle=135°

We know

Length if arc=L

$\boxed{\sf L=\dfrac{\theta}{360}\times 2πr}$

$\\ \sf\longmapsto L=\dfrac{135}{360}\times2π(7)$

$\\ \sf\longmapsto L=\dfrac{27}{72}\times 14π$

$\\ \sf\longmapsto L=\dfrac{27}{36}\times 14π$

$\\ \sf\longmapsto L=\dfrac{9}{12}\times 7π$

$\\ \sf\longmapsto L=\dfrac{63π}{12}$

$\\ \sf\longmapsto L=\dfrac{21π}{4}in$
