Answer:
It's the second option:
0 and 3 are both solutions.
Step-by-step explanation:
h = √(3h) Square both sides:
h^2 = 3h
h^2 - 3h = 0
h(h - 3) = 0
h = 0, 3.
If we plug h = 0 into the original equation:
0 = √(3*0) = 0 so this is a root.
x = 3:
3 = √(3*3) = 3 so this is also a root.
Answer:
No, it is <em>not</em> a right triangle.
Step-by-step explanation:
We know that there are <em>2 legs </em>and <em>1 hypotenuse</em>. The <em>hypotenuse is 76</em> because it is the<em> largest number</em>. And the two <em>legs are 73 and 26</em>. Now to find if it is a right triangle we will take <em>73 and multiply it by itself</em>, which is <em>5,329</em>. Now we will do the same with 26 and we get <em>676.</em> Then we <em>add 676 to 5,329</em> and we get <em>6,005</em>. Because we are trying to find the hypotenuse, we have to find what number <em>when squared</em> makes<em> 6,005</em>. Since <em>76 x 76 = 5,776</em> it is<em> not a right triangle. </em>
Here is an image of the triangle:
Sin and cos functions can never be equal to 5. They can never be greater than 1! Both!
You can think of sin and cos functions as projections (that is how i do). Imagine xy coordinate system. Draw a circle which center (center of circle) is in center of xy coordinate system. Let radius of that circle be one (you can take one to be any length you want).
Now, x - axis and any radius of that circle make an angle.
NOW HERE IS IMPORTANT PART:
-projection of that radius on x-axis is cosine of the angle that radius and x-axis make.
-projection of that radius on y-axis is sinus of the angle that radius and x-axis make.
From that you can see that projections cannot ever be greater than 1.
