Answer:

6) Option 4

7) Option 4

8) Option 1

Step-by-step explanation:

1.31×(10^-5) = 1.131/10⁵

= 1.132/100000

= 0.00001132 (option 4)

7) 3.76×10⁴ + 5.5×10²

10²(3.76×10² + 5.5)

10²(376 + 5.5)

10²(381.5)

10²(3.815×10²)

3.815×10⁴ (option 4)

8) (4×10³)(5×10⁷)

4×10³×5×10⁷

4×5×10³×10⁷

(4×5)(10^(3+7)

(4.5)×(10^(3+7)) (option 1)

That . represents multiplication

Further simplified below:

20×10¹⁰

2.0×10¹¹

Which of the following trigonometric ratios are correct?
den301095 [7]

Hi there! In this problem, you should have the knowledge of three basic Trigonometric Ratio.

  • sinA = opposite/hypotenuse
  • cosA = adjacent/hypotenuse
  • tanA = opposite/adjacent

Now that we know three basic ratio. Let's check each choices!

  • sin50° = d/c

This choice is wrong because we focus on the 50° angle. When we focus on 50°, sin50° should be d/x and not d/c.

  • sin50° = c/x

This choice is also wrong because in ratio, it's cos50° that adjacent/hypotenuse.

  • tan50° = d/c

This choice is correct! As ratio states, tanA = opposite/adjacent.

  • tan50° = x/c

This choice is wrong. x/c is a reciprocal of cosine which is 1/cos. We call the reciprocal of cosine as secant or sec in short.

  • cos50° = x/d

This choice is wrong as x/d is a reciprocal of sine which is 1/sin. We call the reciprocal of sine as cosecant or cosec/csc in short.

  • cos50° = c/x

This choice is right by the ratio. Nothing really much to explain since we follow by ratio that is defined.

Answer

  • tan50° = d/c
  • cos50° = c/x

Questions can be asked through comment.

Furthermore, tan also has its reciprocal form itself which is called cotangent also known as cot in short.

Hope this helps, and Happy Learning! :)
