Answer:

Surface Area = 82.8 square meters

Volume = 37.96 cubic meters

Surface area:

6 × 2 = 12

9 × 2 = 18

8.8 × 6 = 52.8

12 + 18 + 52.8 = 82.8

Volume:

6 × 2 × 9.49 = 113.88

113.88 ÷ 37.96

Answer:

Mark as brainliest if helped Thanks!

Step-by-step explanation:

funtion is:

$y = \frac{x^2 -1}{2x + 1}$

therefore $\\\frac{dy}{dx}\\$ is

$\frac{d\frac{x^2 -1}{2x + 1}}{dx}$

$\frac{\frac{x^2 -1}{2x + 1}}{x}$

$\frac{x^2 -1}{(2x+1) x}$

Now

$\int\limits^2_0 {\frac{x^2 +x +1 }{4x^2 +4 + 1} } \, dx$

(Calculation of this it too long and it is hard to type on brainly)

here is the answer though....

Evaluate h-2g for h = 4 and g = 32.

IRISSAK [1]

We have a subtraction between two terms: h and 2g. Let's see the value of each term:

h is 4, it's already given.

2g means twice g, and g is 32. So, 2g is 64

So, the subtraction is

$4-64 = -60$

Mr. Blue's first year salary is $30,000 and it doubles each year. What is the explicit rule for the sequence in simplified form?

vekshin1

Mr. Blue' salary is an illustration of a geometric sequence

The explicit rule of Mr. Blue 's salary is an = 30000 * 2^(n - 1)
The recursive rule of Mr. Blue's salary is an+1 = 2an; a1 = 30000

<h3 /><h3>How to determine the explicit formula?</h3>

Mr. Blue's salary is a geometric sequence with the following parameters:

First term, a1 = 30000

Rate, r = 2

The explicit rule is calculated as:

an = a1 * r^(n - 1)

This gives

an = 30000 * 2^(n - 1)

<h3>How to determine the recursive formula?</h3>

The common ratio is calculated as:

r = an+1/an

Substitute 2 for r

2 = an+1/an

Cross multiply

an+1 = 2an

Hence, the recursive rule of Mr. Blue's salary is an+1 = 2an; a1 = 30000
