Answer:
x = i sqrt(14/19) or x = -i sqrt(14/19)
Step-by-step explanation:
Solve for x:
(-38 x^2 - 28)/(x^2 - 5 x - 2) = 0
Multiply both sides by x^2 - 5 x - 2:
-38 x^2 - 28 = 0
Add 28 to both sides:
-38 x^2 = 28
Divide both sides by -38:
x^2 = -14/19
Take the square root of both sides:
Answer: x = i sqrt(14/19) or x = -i sqrt(14/19)
Answer:
sin⁴x - sin²x
sin²x(sin²x - 1)
(1 - cos²x)(1 - cos²x - 1)
(1 - cos²x)(-cos²x)
-cos²x + cos⁴x
cos⁴x - cos²x

Step-by-step explanation:
5 rational number between -47 and 12 are {-46, -45, -44, -43, -42}
<h3>
How to find the rational numbers?</h3>
Remember that any integer is also a rational number.
So, if we want to find 5 rational numbers between -47 and 12, we can just find 5 integers between these two numbers.
To do that, we can just add 1 to the lowest bound, we will et:
-47 + 1 = -46
-45 + 1 = -45
-44 + 1 = -44
-43 + 1= -43
-43 + 1 = -42
So 5 rational number between -47 and 12 are {-46, -45, -44, -43, -42}
