So if you want to have a factored form...
If the zeroes are +4 and +8, you would write
(X-4) (x-8)
Then you would multiply it out to get to quadratic form...
So, (x-4)*(x-8)
X^2 - 12x + 32
Then you would plug it into the formula for axis of symmetry...
X= -b/2a
X=12/2 = 6
X=6
Answer:25sqrt3-25pi/3
Step-by-step explanation:
Assuming the triangle is equilateral, we clearly need to find the radius of the circle, and subtract from the entire area of the triangle.
First, the area of an equilaterail triangle is given by the formula s^2 *sqrt3/4.
Next, the connect the center of the radius to points of tangency. Note this bisects the angle of the equilateral triangle into a 30 degree angle, and connecting radii to points of tangency forms a 90 degree angle, so this is a 30-60-90 triangle. This bisects the side length of the triangle, and the ratio of sides of a 30-60-90. Set this length as x. Thus, we have 4x^2=x^2+25, so 3x^2 =25. Dividing both sides by 3, we get x^2=25/3. Note that we only need x^2, as the formula is x^2 * pi. Hence, the area of the shaded region is 25sqrt3-25pi/3.
Answer:
m=4/-5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
take two pointes: (2,-3); (-3,1)
(2,-3) as (x1,y1). (-3,1) as (x2,y2)
m=(1-(-3))/(-3-2)
m=4/(-5)
That's your slope
Answer:
Carly
Step-by-step explanation:
to figure out what the ratio is you need to put it in fraction form
zoe's team is 8/14
carly's team is 7/17
you need to find a common denominator to figure out who has the higher number of wins
in this case, the common denominator would be 238 or 14 times 17
you multiply both the numerator and the denominator by 17/17 for zoe's fractions
zoe's team has 136/238
carly's team would be multiplied by 14/14
this would give you 98/238
now that both fractions have the same denominator you can determine that carly's team lost more games
