Which of the following functions grows at the same rate as ((x^4)+x)^(1/2)
neonofarm [45]

Answer:

B

Step-by-step explanation:

(x⁴ + x)^½

As x approaches infinity, x⁴ becomes much larger than x.  So:

(x⁴ + x)^½ ≈ (x⁴)^½ = x²

So x² grows at the same rate as (x⁴ + x)^½.

Janet wants to build a fence around her square garden.her garden has an area of 81 square feet.How much fencing will Janet need?
densk [106]

Area of garden = 81 ft²

Area of square = side²

\rm \implies side ^{2}  =  81  \\  \\ \rm \implies side  =   \sqrt{81}  \\  \\ \rm \implies side   =   \sqrt{ {9}^{2} }  \\  \\ \rm \implies side   =  9 \: ft

Perimeter of square = 4 × Side

= 4 × 9

= 36 ft

\therefore Fencing needed by Janet = 36 ft
