Evaluate the integral (tan3x)dx

Mathematics
1 answer:
Ksju [112]3 years ago
5 0
<span>The solution to the problem is as follows:

tan (3x) = sin(3x) / cos(3x) 

let u = cos(3x), du = -3 sin(3x) 

Integrating -1/3 du / u = -1/3 ln (u) = -1/3 ln (abs (cos(3x)) + constant

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

I need 23 by tomorrow morning at the latest!! WILL GIVE BRAINLEST!
beks73 [17]

Answer:

Area: 5x + 10

Perimeter: 2x + 14

Step-by-step explanation:

Area = length times width

Perimeter = length (2) + width (2)

<u>Area:</u>

Multiply the length be the width. That gives you 5 (x + 2).

Then use the distributive property to simplify this expression. That gives you 5x + 10.

<u>Perimeter:</u>

Multiply the width by 2. That gives you 10.

Multiply the length by 2. That gives you 2x + 4

Add the 2 together. That gives you 10 + 2x + 4.

Combine all like terms. That gives you 2x + 14.

Sine, cosine, and tangent to calculate the height of the buildings in the diagram below.
DiKsa [7]

Answer: Around 68.0858 m

Step-by-step explanation:

  • Set the height of 37°-53°-90° triangle as x
  • Set the height of 50°-40°-90° triangle as y
  • The horizontal side both triangles share = 35

To find x                            To find y  

tan(37)=\frac{x}{35} \\\\35tan(37)=x\\\\x=26.37439...                     tan(50)=\frac{y}{35} \\\\35tan(50)=y\\\\y=41.7113757...

To find the height of the building, add the x-value and y-value:

x+y=26.3744+41.7114=68.0858  

<em>I hope this is correct o_o</em>

so, 21x=189
x=9

therefore green pepper= 3x=3×9=27

so the answer is B and you can go for that !
