Given quadratic equation
Using the usual conventions,
a=1, b=6, c=6
Apply the quadratic formula,
substitute a,b & c with numerical values,
simplify:
Answer:
11
Step-by-step explanation:
Triangles HOP and DIP are similar by AA Postulate.
Hence,
TanX = SinX/CosX
TanX = 7/25 ÷ 24/25
Tanx = 7/25 * 25/24
TanX = 7/24...
Answer:
x = y = 2
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = , then
sin45° = = = ( cross- multiply )
x = 2 ( divide both sides by )
x = 2
The triangle is isosceles, base angles both 45°, then legs are congruent, so
x = y = 2
Going from right to left top to bottom, the quadrants are
1- Top right,
2- Top left
3- Bottom left
4- Bottom right
The point (5,-2) would be in the 4th plane BUT
It wants (-x,y) so chance the POSITIVE 5 to NEGATIVE
Our new point is (-5,-2)
This lies on the bottom left or the 3rd quadrant plane
