For problems a - d, write the function in the form LaTeX: y=ab^x. y = a b x . a) LaTeX: y=3\sqrt{4^{2x}} y = 3 4 2 x b) LaTeX: y
elixir [45]

Step-by-step explanation:

To write the equation in LaTeX in form y = ab^x  or ab^x for y = abx .........(1)

(a) LaTeX: y=3\sqrt{4^{2x}}  y = 3 4 2 x can be written in mathematical form as

y=3\sqrt{4^{2x}} ; y = 342x

on comparing with equation (1) we get a =3 and b =4

⇒y = 34^x or 34^x

(b) LaTeX: y=\frac{\sqrt[3]{5^{3x}}}{2} y = 5 3 x 3 2 can be written in mathematical form as

y=\frac{\sqrt[3]{5^{3x}}}{2} ; y = 342x

on comparing with equation (1) we get a =0.5 and b =5

⇒y = \frac{1}{2}5^x

(c)LaTeX: y=8^{x+2} y = 8 x + 2 can be written in mathematical form as

y=8^{x+2}

on comparing with equation (1) we get a =64 and b =8

y = 64 . 8^x

(d)LaTeX: y=\frac{3^{2x+1}}{\sqrt{3^{2x}}}  can be written in mathematical form as

y=\frac{3^{2x+1}}{\sqrt{3^{2x}}} = 3^{x+1} = 3 . 3^x

on comparing with equation (1) we get a =3 and b =3

y = 3 . 3^x

Find the radius r of the sphere.
AleksandrR [38]

Given:

The volume of the sphere = 12348π in³

To find the radius of the sphere.

Formula

The volume of a sphere of radius r is

V = \frac{4}{3} \pi r^{3}

According to the problem,

\frac{4}{3} \pi r^{3} = 12348\pi

Eliminating π from both the side.

or, \frac{4}{3} r^{3}= 12348

or, r^{3}=\frac{(12348)(3)}{4}

or, r^{3}=9641

or, r=\sqrt[3]{9261}

or, r=21

Hence,

The radius of the sphere is 21 inches.
