Multiply both sides by (x-2)(x+1) to clea fractions
x(x+1)+(x-1)(x-2)=(-1)(x-2)(x+1)
distribute
x^2+x+x^2-3x+2=-x^2+x-2
add like terms
2x^2-2x+2=-x^2+x+2
add x^2 to both sdes
3x^2-2x+2=x+2
minus x from both sides
3x^2-3x+2=2
minus 2 both sides
3x^2-3x=0
factor
(3x)(x-1)=0
set to zero

3x=0
x=0

x-1=0
x=1

There are seven days in a week so divide the 360 by the 7 51 3/7 minutes everyday
Subtract 45 from it 6 3/7
So the answer is he jogged 6 minutes and around 26 seconds everyday
(Concert the 3/7 to seconds by my tip lying it by 60)

Point P lies on circle C, x^2+y^2=36. There are two unique tangents to circle D, x^2+y^2=18 that pass through point p. What is t
Anastasy [175]

Answer:

90°

Step-by-step explanation:

Circle C has radius √36 = 6

Circle D has radius √18 = 3√2

As the D radius intersecting either point of tangency, does so at a right angle.

The half angle θ between the tangents is

sinθ = 3√2 / 6 = ½√2

θ = 45°

so the angle between the tangents is 2(45) = 90°

LekaFEV [45]
1/3 of the large circle, assuming like 1/3 like pizza cut
then cut into 1/2 of that, assuming again like pizza cut

1/2 of what it was=1/2 of 1/3=1/6 of original


original=whole circle
1/6 of whole circle=1/6 of 360=360/6=60
