Answer:
= 3.1415926...= c/d
Step-by-step explanation
Pie is infinite so there is no simple answer.
circumference divided by the diameter = pie
$18 = 14 + 0.20(t)
- 14
4 = 0.20t
Divide 4 by 0.20
t = 20
0.20 * 20 = 4
4 + 14 = 18
Because it only charged her for texts after 450, its 450 + 20.
470. She sent 470 texts that month.
Answer:
A)z12 B)9x^3 y^4
Step-by-step explanation:
the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0
13x^2-16x = x^2 -x
we need to get in it the standard form
subtract x^2 from each side
12x^2 -16x = -x
add x to each side
12x^2 -15x = 0
12x^2 -15x -0 =0
a=12 b=-15 c=0
b^2 -4ac
the discriminant = b^2
b^2 = (-15)2 = 225
X-intercept:(-2,0)
Y-intercept:(0, -4/9)
