Answer:
x = 16°, tan x = 0.3
Step-by-step explanation:
![sin \: 2x = cos \: (3x + 10) \\ cos(90 - 2x) = cos \: (3x + 10) \\ 90 - 2x = 3x + 10 \\ 90 - 10 = 3x + 2x \\ 80 = 5x \\ x = \frac{80}{5} \\ \huge \red{ \boxed{x = 16 \degree }}\\ \\ tan \: x = tan \: 16 \degree \\ = 0.2867453858 \\ = 0.3](https://tex.z-dn.net/?f=sin%20%5C%3A%202x%20%3D%20cos%20%5C%3A%20%283x%20%2B%2010%29%20%5C%5C%20cos%2890%20-%202x%29%20%3D%20cos%20%5C%3A%20%283x%20%2B%2010%29%20%20%5C%5C%2090%20-%202x%20%3D%203x%20%2B%2010%20%5C%5C%2090%20-%2010%20%3D%203x%20%2B%202x%20%5C%5C%2080%20%3D%205x%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B80%7D%7B5%7D%20%20%5C%5C%20%20%5Chuge%20%5Cred%7B%20%5Cboxed%7Bx%20%3D%2016%20%5Cdegree%20%7D%7D%5C%5C%20%20%5C%5C%20tan%20%5C%3A%20x%20%3D%20tan%20%5C%3A%2016%20%5Cdegree%20%20%5C%5C%20%3D%200.2867453858%20%5C%5C%20%20%3D%200.3)
1. Proof
1. Proofln(x) dx. set. u = ln(x), dv = dx. then we find. du = (1/x) dx, v = x.
1. Proofln(x) dx. set. u = ln(x), dv = dx. then we find. du = (1/x) dx, v = x.substitute. ln(x) dx = u dv.
1. Proofln(x) dx. set. u = ln(x), dv = dx. then we find. du = (1/x) dx, v = x.substitute. ln(x) dx = u dv.and use integration by parts. = uv - v du.
1. Proofln(x) dx. set. u = ln(x), dv = dx. then we find. du = (1/x) dx, v = x.substitute. ln(x) dx = u dv.and use integration by parts. = uv - v du.substitute u=ln(x), v=x, and du=(1/x)dx.
hope this will help u
Answer:
-75
Step-by-step explanation:
3(-30)=-90
-90+15 is -75
Answer:
200 cm²
Step-by-step explanation:
Find the areas of all of the faces
17 × 2 = 34 (Top Face)
8 × 15 = 120 (Both Triangles)
15 × 3 = 30 (Bottom Face)
8 × 2 = 16 (Back Face)
Add them all together
120 + 34 + 30 + 16 = 200 cm²
Answer:
69.72 inches.
Step-by-step explanation:
The best point estimate for the average height if males in the United States is...
For large samples, as we have here, the best point estimate is the sample mean. In this question, the sample mean is of 69.72 inches, so the answer is 69.72 inches.
