Answer:
2 and 5
Step-by-step explanation:
five plus two equals 7
Answer:
Step-by-step explanation:
-50 plus so above the number so like -51.5
Answer:
2c -7 ≤ -29
Step-by-step explanation:
2c -7 ≤ -29
c = the number
![sinx=cosx-1 \\ \\ sinx-cosx=-1](https://tex.z-dn.net/?f=sinx%3Dcosx-1%20%5C%5C%20%20%5C%5C%20%0Asinx-cosx%3D-1)
Using the identity:
![sinx-cosx=- \sqrt{2}cos( \frac{ \pi }{4}+x)](https://tex.z-dn.net/?f=sinx-cosx%3D-%20%5Csqrt%7B2%7Dcos%28%20%5Cfrac%7B%20%5Cpi%20%7D%7B4%7D%2Bx%29%20%20)
, we get:
![- \sqrt{2}cos( \frac{ \pi }{4}+x)=-1 \\ \\ cos( \frac{ \pi }{4}+x)= \frac{1}{ \sqrt{2} } \\ \\ ](https://tex.z-dn.net/?f=-%20%5Csqrt%7B2%7Dcos%28%20%5Cfrac%7B%20%5Cpi%20%7D%7B4%7D%2Bx%29%3D-1%20%5C%5C%20%20%5C%5C%20%0Acos%28%20%5Cfrac%7B%20%5Cpi%20%7D%7B4%7D%2Bx%29%3D%20%5Cfrac%7B1%7D%7B%20%5Csqrt%7B2%7D%20%7D%20%5C%5C%20%20%5C%5C%20%0A%20)
There are two solutions to this equation:
1) ![\frac{ \pi }{4}+x= \frac{ \pi }{4} \\ \\ x=0](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%5Cpi%20%7D%7B4%7D%2Bx%3D%20%5Cfrac%7B%20%5Cpi%20%7D%7B4%7D%20%5C%5C%20%20%5C%5C%20%0Ax%3D0%20%20)
Since the period of cosine is 2π, so 0 + 2π = 2π will also be a solution to the given equation
2)
Therefore, there are 3 solutions to the given trigonometric equation.
Answer:
4 to 7 is pretty much 4 divided by 7 which = 4/7 and 7/4 is 1 3/4. which is obviously greater. So they both equal different answers.
