Yes it is true:
(1 - cos^2 x) = sin^2 x Sqr.(1 - cos^2 x) = sin x and (-sinx) True, since sin x negative. Also, x terminates in quadrant 3 and 4. Hope this is helpful
130 you multiply the left side by 13 to get the right side.
Hi there!
We know that the formula for the area of a rectangle is height * width. Thus, we can multiply these two expressions together:
![2x^4\cdot (x^2+8x+15)\\](https://tex.z-dn.net/?f=2x%5E4%5Ccdot%20%28x%5E2%2B8x%2B15%29%5C%5C)
Now, we know through the distributive property that we can distribute the
to everything in the parenthesis. Once this is done, we get:
![2x^4 \cdot x^2+2x^4\cdot8x+2x^4\cdot15](https://tex.z-dn.net/?f=2x%5E4%20%5Ccdot%20x%5E2%2B2x%5E4%5Ccdot8x%2B2x%5E4%5Ccdot15)
Now, we know through the power rule that when two exponents are multiplied together with the same base, the exponent can be added together
. This then would make our equation:
![2x^{4+2}+16x^{4+1}+30x^4\\](https://tex.z-dn.net/?f=2x%5E%7B4%2B2%7D%2B16x%5E%7B4%2B1%7D%2B30x%5E4%5C%5C)
Giving us for our final answer:
![2x^{6}+16x^{5}+30x^4\\](https://tex.z-dn.net/?f=2x%5E%7B6%7D%2B16x%5E%7B5%7D%2B30x%5E4%5C%5C)
Hope this helps!

In the given figure, the angles 5 and 6 form Vertical opposite angle pair.
so, correct choice is Vertical
Answer:
The hypotenuse( longer side) of the triangle = ![c^{2} = a^{2} +b^{2} \\Therfore, c = \sqrt a^{2} +b{2}\\ \\](https://tex.z-dn.net/?f=c%5E%7B2%7D%20%3D%20a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%5C%5CTherfore%2C%20c%20%3D%20%5Csqrt%20a%5E%7B2%7D%20%2Bb%7B2%7D%5C%5C%20%5C%5C)
Step-by-step explanation:
Here, side =c
Therfore, area = c *c
That is
= 50
= 3250 = 57 units sq
