Answer:
- 15x² + 7x + 1
Step-by-step explanation:
Given
2x² - 9 - 17x² + 10 + 7x ← collect like terms
= (2x² - 17x² ) + 7x + 1
= - 15x² + 7x + 1
A circle is a geometric object that has symmetry about the vertical and horizontal lines through its center. When the circle is a unit circle (of radius 1) centered on the origin of the x-y plane, points in the first quadrant can be reflected across the x- or y- axes (or both) to give points in the other quadrants.
That is, if the terminal ray of an angle intersects the unit circle in the first quadrant, the point of intersection reflected across the y-axis will give an angle whose measure is the original angle subtracted from the measure of a half-circle. Since the measure of a half-circle is π radians, the reflection of the angle π/6 radians will be the angle π-π/6 = 5π/6 radians.
Reflecting 1st-quadrant angles across the origin into the third quadrant adds π radians to their measure. Reflecting them across the x-axis into the 4th quadrant gives an angle whose measure is 2π radians minus the measure of the original angle.
Answer: Charmaine Diyoza: "Come on, Kane. Without graveyard McCreary, my internal problem is solved. Without the Red Queen, our problem external is. This is how we get to peace."
Step-by-step explanation: The 100
The second and the third one are similar.
Answer:
305
Step-by-step explanation:
This sequence es the sum of 3
5+3 =8
8+3 = 11
then
101 = 100 + 1
the fisrt date is 5
the another 100:
100*3 = 300
300 + 5 = 305
