Answer:
9.055
Step-by-step explanation:
I am going to make what is hopefully not an incorrect assumption and say that since the segmentXSZ is black and the other lines are blue, that XS is congruent to ZS. If that be the case we have a side in each triangle that is congruent to each other and an angle that is marked as congruent. Angles XSW and ZSY are vertical angles. By definition, vertical angles are congruent. In each triangle, then, we have an angle, a side and an angle which gives us the congruency postulate ASA.
The statements that describe a triangular prism are:
- It has one base.
- It has three lateral faces.
- Its lateral faces are rectangular.
<h3>What is a triangular prism?
</h3>
A triangular prism is a three-dimensional object that is made up of one base that has the shape of a triangle and three lateral sides that have the shape of a rectangle. A triangular prism has 5 faces, 9 edges and 6 vertices.

Answer: ![f'(1)=\dfrac{4}{2y+1}](https://tex.z-dn.net/?f=f%27%281%29%3D%5Cdfrac%7B4%7D%7B2y%2B1%7D)
<u>Step-by-step explanation:</u>
To find the tangent, you need to find the derivative with respect to x.
Then substitute x = 1 into the derivative.
Given: 0 = 2x² - xy - y²
Derivative: 0 = 4x - y' - 2yy'
Solve for y': 2yy' + y' = 4x
y'(2y + 1) = 4x
![y'=\dfrac{4x}{2y+1}](https://tex.z-dn.net/?f=y%27%3D%5Cdfrac%7B4x%7D%7B2y%2B1%7D)
![\text{Substitute x = 1:}\quad y'(1)=\dfrac{4}{2y+1}](https://tex.z-dn.net/?f=%5Ctext%7BSubstitute%20x%20%3D%201%3A%7D%5Cquad%20y%27%281%29%3D%5Cdfrac%7B4%7D%7B2y%2B1%7D)
15% - 40. -25 = 1500 percent take out the zero because they have zero value and your left with 15 which is 15%
