$24 x 6 = 144 Minus the $6 she spent per week -$36 = $108
I guess that is what you meant when you typed "she saved $24 each week she saves $6???
The vertex is (-1,1)
Explanation
The vertex formula to find the x coordinate of the formula is -b/2a
So we plug in the values into the formula which is
-4/2(2)
Simplify it
-4/4
=-1
-1 is now the x cord of the vertex.
So now we will plug in the x into the quadratic equation which is 2x^2+4x+3
2(-1)^2 + 4(-1) + 3 = 2 -4 +3
Simplify it
5 - 4= 1
Y=1
So the Coordinates of the vertex is (-1,1)
Tangent always meets radius at 90° angle.
Angle ABC = 90° so Pythagoras' theorem applies.
r² + 4² = (r+2)²
r² + 16 = r² + 4r + 4
12 = 4r
r = 3
42%
You have essentially a fraction, 21/50, which gives you a decimal of 0.42, or 42%.
(Flipped a total of 50 times, of those, it landed red side up 21 times, so 21/50)
