Diagonals AC and BD of a rhombus ABCD meet at O . If AC=8cm and BD=6cm , find sin √OCD.

Answers

Answer 1
Answer: Due to the symmetry of the rhombus; AC = 2OC and BD = 2OD. Hence, we can say that OC is 4cm and OD is 3cm. Then we can say that sin(OCD) = OC/CD [CD = sqrt(OC^2 + OD^2)].

At the end, did you mean sqrt(sin(ocd)) or sin(sqrt(ocd)). Either way you can find angle OCD by doing arcsin(OC/CD).

Answer:

None

Step-by-step explanation:

There is a solution when the two lines intersect, because the lines have the same slope (and different y intercepts) they will never intersect. Therefore there are no solutions

Which of the following is true? A Tangent is positive in Quadrant I. B Sine is negative in Quadrant II. C Cosine is positive in Quadrant III. D Sine is positive in Quadrant IV.

Answers

Answer:  The correct option is (A) Tangent is positive in Quadrant I.

Step-by-step explanation:  We are given to select the correct statement from the options provided.

The rule of signs for the trigonometric ratios in the four quadrants are as follows :

Quadrant I :    All the three ratios, tangent, sine and cosine are positive.

Quadrant II :   Only sine is positive, cosine and tangent are negative.

Quadrant III :  Only tangent is positive, sine and cosine are negative.

Quadrant IV :  Only cosine is positive, sine and tangent are negative.

Therefore, using the above rules, we can say that the options (B), (C) and (D) are incorrect.

Option (A) is correct because all the ratios are positive in Quadrant I and so is tangent.
The true statement in that a tangent is positive in quadrant I.

Answers: Shasta increases the amount she saves each month by 5%. The amount of cell phone subscribers in a small town increases by 75% each year.The price of a stock goes up 12% each year. 
Exponential growth consistently raises the base amount/number to a certain degree. The above answers increase a digit by a number of percentage steadily over a period of time. 

Answer: Shasta increases the amount she saves each month by 5%.

The amount of cell phone subscribers in a small town increases by 75% each year.

The price of a stock goes up 12% each year.

Step-by-step explanation:

The exponential growth happens when a given quantity increases by the constant rate of proportion in each given time period.

  • Shasta increases the amount she saves each month by 5%.

This is an example of exponential growth with rate of increase 5%.

  • The population over the last decade of the Black Rhino is such that it is nearing extinction.

This shows decrease in population , so this cannot be example of exponential growth.

  • A tennis tournament starts with 64 participants. Each round, half the players are eliminated.

This shows decrease in participants , so this cannot be example of exponential growth.

  • The amount of cell phone subscribers in a small town increases by 75% each year.

This is an example of exponential growth with rate of increase 75%.

  • The price of a stock goes up 12% each year.

This is an example of exponential growth with rate of increase 12%.
