Answer:

F)\displaystyle \:  100\pi{ x}^{8} {y}^{2}  {z}^{ 6}

Step-by-step explanation:

we are given r and the formula

we want to find the surface area of the shpare with the given r

to do so

we need our algebra skills

substitute the value of r:

\displaystyle \: S = 4\pi( {5x}^{4} y {z}^{ 3} {)}^{2}

recall law of exponent

\displaystyle \:  ({x}^{m}  {)}^{n}  \iff \:  {x}^{mn}

to simplify:

\displaystyle \: S = 4\pi({ {5}^{2} x}^{4 \times 2} {y}^{1 \times 2}  {z}^{ 3 \times 2} )

simplify multiplication:

\displaystyle \: S = 4\pi({ 25x}^{8} {y}^{2}  {z}^{ 6} )

distribute:

\displaystyle \: S = 100\pi{ x}^{8} {y}^{2}  {z}^{ 6}

hence our answer is F

notsponge [240]

Answer:

t_{n}=t_{n-1}+t_{n-2} +t_{n-4}

Step-by-step explanation:

t_{n}=multiple ways to climb a tower

When n = 1,

tower= 1 cm  

t_{1}= 1

When n = 2,

tower =2 cm   

t_{2}= 2

When n = 3,

tower = 3 cm

it can be build if we use three 1 cm blocks

t_{3} = 3

When n = 4,

tower= 4 cm

it can be build if we use four 1 cm blocks

t_{4} = 6

When n > 5

tower height > 4 cm

so we can use 1 cm, 2 cm and 4 cm blocks

so in that case if our last move is 1 cm block then t_{n-1} will be

n —1 cm

if our last move is 2 cm block then t_{n-2} will be

n —2 cm

if our last move is 4 cm block then t_{n-4} will be

n —4 cm

 

t_{n}=t_{n-1}+t_{n-2} +t_{n-4}
