For the first one, we know that is a right angle. right angles are 90 degrees. if we subtract 90 - 49 that equals 41. so the second value needs to equal 41. since we have a 3 there already, we are going to subtract 41-3, which is 38. x = 38
Use an app on your phone just make sure you pick a gods one it will give you the answer I am not that good at math tho
Answer:
That will be;
3x^2 + 5x -6 = 0
Step-by-step explanation:
Here, we want to write 3x^2 + 5x = 6 in the form
ax^2 + bx + c = 0
That will be;
3x^2 + 5x -6 = 0
We can simply get it by bringing the value 6 from the right hand side of the equation to the left hand side of the equation
Answer:
It is increasing from -1 to 1.
It is decreasing from negative infinity to -1, then decreases again from 1 to positive infinity.
IF the central angle is in degrees then the
arc length = (12 / 360) * circumference
arc length = (1 / 30) * 2 * PI * 30
arc length = 2 * PI inches
arc length =
