What is the value of sinθ given that (3, −7) is a point on the terminal side of θ ? −758√58 758√58 358√58 −358√58?
Svetach [21]

Answer:

\boxed{\sin(\theta)=-\frac{7}{58}\sqrt{58}}

Step-by-step explanation

The given point (3,-7) tells us that the terminal side of \theta is in the fourth quadrant.


From the diagram in the attachment,

We can use the Pythagoras Theorem to find the length of the hypotenuse of the right triangle.

Let the hypotenuse be h\: units. Then,

h^2=7^2+3^2


h^2=49+9


h^2=58


\Rightarrow h=\sqrt{58}


Now we use the sine ratio;


\sin(\theta)=\frac{Opposite}{Hypotenuse}.


But since the terminal side of \theta is in the fourth quadrant, the sine ratio must be negative.


This implies that;


\sin(\theta)=-\frac{7}{\sqrt{58}}.


We rationalize the denominator to get;


\sin(\theta)=-\frac{7}{58}\sqrt{58}.

How many cubes with side lengths of 1/3 to fill the prism
Marianna [84]

I believe I am correct.

Multiply the side values together to get the volume of the prism.

1 x 2 2/3x 2/3 = 1.7(repeating)

Then divide 1.7(repeating) by 1/3 and you end up with 5 1/3.

Hope this helps!

And this problem your multiplying 12 by 6 was 12 called in this math problem
Lynna [10]

To multiply one number ( a multiplicand ) by another ( a multiplier ) means to repeat a multiplicand as an addend times. The result of multiplying is called a product. The operation of multiplication is written as: 12 x 6, or 12 * 6

Multiply 12 by 6

6 is called the Multiplier

12 is called the Multiplicand

72 is called the Product

Therefore, a multiplicand and a multiplier are called factors or multipliers.

Hope that helps!!!! : )
