Use a calculator to find an approximate solution to the equation. Round any intermediate work and steps to three decimal places.

Mariana [72]

Given;
6Ln (x + 2.8) = 9.6

We will transpose 6 in the Ln, so that we will leave Ln alone.
Ln (x + 2.8) = 9.6/6 = 1.6

we divide the 9.6 to 6 and we get 1.6

x + 2.8 = e^1.6
e^ for the substitution of Ln

x = e^1.6 - 2.8
insert the e^(1.6) in the calculator and you will get 4.95303242439511 and subtract 2.8 and you will get the answer.

x = 2.153
2.153 is the final answer in this question.

5 5 I think of a number, treble it then add on 3, the result is equal to 6. Find the value of the original number I thought of.

Licemer1 [7]

Let the number be x

If 3 is added to tripple the number then the result is 6

$\\ \sf\longmapsto 3x+3=6$

$\\ \sf\longmapsto 3x=6-3$

$\\ \sf\longmapsto 3x=3$

$\\ \sf\longmapsto x=1$

What is the volume of the cylinder? Round your answer to the nearest whole number??

andreyandreev [35.5K]

Answer:

141

Step-by-step explanation:

1. The volume of a cylinder is $\pi r^2h$ , where r = radius and h = height. In this case, the height is 5 feet and the radius is 3 feet.

Solving Volume

Step 1: Plug in values

$\pi * 3^2 * 5$

Step 2: Simplify.

$3.14 * 9 * 5$
$28.26 * 5$
$141.3$
141.3 ≈ 141

Therefore, the volume of the cylinder is 141 ft^3 (but don't put ft^3, as mentioned in the problem).

Have a lovely rest of your day/night, and good luck with your assignments! ♡
