sin3A/sinA-Cos3A/CosA=2​

Answers

Answer 1

Answer:

sin3A/sinA-Cos3A/CosA=2​

taking LCM

= Sin3A.CosA - Cos3A. SinA

     SinA . CosA

= Sin(3A-A)

  SinA . CosA

=  Sin2A          

   SinA . CosA

= 2 SinA. CosA

    SinA . CosA

sun^4A+sin^2Acos^2A=sin^2A​

Answers

Step-by-step explanation:

sin⁴A + sin²Acos²A = sin²A

Proving the left hand side ( LHS)

That's

sin⁴A can be written as ( sin²A)(sin ²A)

So we have

( sin²A)(sin ²A) + sin²Acos²A

Next factor sin²A out

That's

sin²A ( sin²A + cos²A)

Using trigonometric identities

That's

sin²A + cos²A = 1

Simplify the expression

That's

sin²A × 1

We have the final answer as

sin²A

As proven

Solve for x: 4(x + 3) - 2 = 14

Answers

Answer:

X = 1

Step-by-step explanation:

4(x + 3) - 2 = 14

4x + 12 - 2 = 14

4x + 10 = 14

4x = 4

x = 1

Answer:

x = 1

Step-by-step explanation:

4(x+3) - 2 = 14

4x + 12 - 2 = 14

4x +10 = 14

4x = 14 - 10

4x = 4

x = 4/4

a rectangular with a perimeter of 32 cm has a base of x-3 cm and a height of 2x+7 cm what are the length in cm of the rectangle base an height​

Answers

Answer:

Step-by-step explanation:

Perimeter = 32

length = x - 3

width = 2x + 7

Perimeter = 2* Length + 2* width

Perimeter = 2*(x-3) + 2(2x + 7) = 32         Remove the brackets.

2x - 6 + 4x + 14 = 32                                  Combine

6x + 8 = 32                                                 Subtract 1 from both sides

6x = 32 - 8

6x = 24                                                       Divide by 6

x = 24/6

x = 4

So the base = x - 3 = 4 - 3 = 1

The height  = 2*4 + 7 = 8 + 7 = 15

. When the process of solving a linear inequality results in the variable being eliminated with a false statement remaining, what does this mean about the solution set of the inequality?

Answers

Answer:

No Solution

Step-by-step explanation:

When we solve linear inequalities using any one the methods such as

1) Elimination  or

2) Substitution

And we get  the variable eliminated with a false statement remaining, this means there is no solution.

In other words the solution does not exist or the solution is not possible in the given range or the values given are false.

But when the values are true we get a solution for the variable solved.

In the elimination method we eliminate the same terms by addition or subtraction after making them equal.

And the substitution method requires putting the values of one variable in place of another.

line g has a slope of 9/5. line h is perpendicular to g. what is the slop of line h?

Answers

Answer:

-5/9

Step-by-step explanation:

Note. If the line is parallel, then the slope is shared. If the line is perpendicular (directly opposite), it means to flip the sign as well as the fraction.

The slope of line g is 9/5. This means that the slope of line h, (which is perpendicular to line g), would be the opposite, or -5/9

-5/9 is your answer.
