Answer:

0.348

Step-by-step explanation:

The fraction 15/43 is already in the simplest form, so it isn't possible to reduce it any further.

This is a PROPER FRACTION once the absolute value of the top number or numerator (15) is smaller than the absolute value of the bottom number or denomintor (43).

The fraction 15/43 is equal to 15÷43 and can also be expressed in decimal form as 0.348837.

Solve 3[–x + (2 x + 1)] = x – 1.
otez555 [7]
Solution
3(-x+(2x+1))=x-1
3(x+1)=x-1
3x+3=x-1  collect like terms
3x-x=-1-3
2x=-4  divide both side by 2
x=-4/2=-2

Answer:

Let \left(1+\frac{1}{\tan^{2}A} \right)\cdot \left(1+\frac{1}{\cot^{2}A} \right), we proceed to prove the trigonometric expression by trigonometric identity:

1) \left(1+\frac{1}{\tan^{2}A} \right)\cdot \left(1+\frac{1}{\cot^{2}A} \right) Given

2) \left(1+\frac{\cos^{2}A}{\sin^{2}A} \right)\cdot \left(1+\frac{\sin^{2}A}{\cos^{2}A} \right)   \tan A = \frac{1}{\cot A} = \frac{\sin A}{\cos A}

3) \left(\frac{\sin^{2}A+\cos^{2}A}{\sin^{2}A} \right)\cdot \left(\frac{\cos^{2}A+\sin^{2}A}{\cos^{2}A} \right)    

4) \left(\frac{1}{\sin^{2}A} \right)\cdot \left(\frac{1}{\cos^{2}A} \right)    \sin^{2}A+\cos^{2}A = 1

5) \frac{1}{\sin^{2}A\cdot \cos^{2}A}

6) \frac{1}{\sin^{2}A\cdot (1-\sin^{2}A)}    \sin^{2}A+\cos^{2}A = 1

7) \frac{1}{\sin^{2}A-\sin^{4}A} Result
