Can anyone solve ? This one is beyond me

Makovka662 [10]

Answer:

$Rate = 0.13$

Step-by-step explanation:

Given

$y = \sqrt[3] x$

Required

Determine the average rate of change over [2,7]

This is calculated as:

$Rate = \frac{f(b) - f(a)}{b - a}$

In this case:

$b = 7$ and $a = 2$

So, we have:

$Rate = \frac{f(7) - f(2)}{7-2}$

$Rate = \frac{f(7) - f(2)}{5}$

From the table:

f(7) = 1.91

f(2) = 1.26

$Rate = \frac{1.91 - 1.26}{5}$

$Rate = \frac{0.65}{5}$

$Rate = 0.13$

Answer:

A. Circular base of the bucket

B. Bucket

Step-by-step explanation:

We are given that,

1. The dimensions of the rectangular prism are,

Length = 2 feet, Width = 3 feet and Height = 5 feet.

So, we have,

Area of the rectangular base = $Length\times Width$

i.e. Area of the rectangular base = $2\times 3$

i.e. Area of the rectangular base = 6 feet²

Also, we have,

Volume of the prism = $whl$

i.e. Volume of the prism = $3\times 5\times 2$

i.e. Volume of the prism = 30 feet³

2. The dimensions of the cylinder are given as,

Diameter = 3 feet i.e Radius = $\frac{3}{2}$ = 1.5 feet

Height = 5 feet

Then, we have,

Area of the circular base = $\pi r^2$

i.e. Area of the circular base = $\pi (1.5)^2$

i.e. Area of the circular base = $2.25\pi$

i.e. Area of the circular base = 7.07 feet²

Also, we have,

Volume of the cylinder = $\pi r^{2}h$

i.e. Volume of the cylinder = $\pi (1.5)^{2}\times 5$

i.e. Volume of the cylinder = $\pi 2.25\times 5$

i.e. Volume of the cylinder = $11.25\pi$

i.e. Volume of the cylinder = 35.34 feet³

PART A: Since we have,

Area of the rectangular base = 6 feet² < 7.07 feet² = Area of the circular base

Hence, the circular base of the bucket is larger in area.

PART B: We have,

Volume of the prism = 30 feet³ < 35.34 feet³ = Volume of the cylinder

Hence, the bucket is larger in volume.
