The X (1) axis represents the number of hours, and the Y (75) axis represents the number of dollars. When 0 hours are passed, 0 hours are payed (0,0) 1 hour 75 dollars are payed (1, 75) 2 hours 150 dollars is payed (2, 150) and so on
Vertex form:
y-k=a(x-h)^2
h=-2,k=-20,y=-12 when x=0
thus;
-12+20=a(0+2)^2
8=4a
a=2
Equation:
y+20=2(x+2)^2
y+20=2(x^2+4x+4)
f(x)=2(x^2+4x+4)-20
f(x)=2x^2+8x+8-20
f(x)=2x^2+8x-20
Answer to your question:
D = d < -6
(-2)^3
12^0
I don't know the rest
Answer: 9 centimeters
Step-by-step explanation:
Add up all the sides, 6 + 10 + 11 = 27,
Since it’s the perimeter of an equilateral triangle, you do
27 / 3 = 9, which is the answer.
