Answer:
(1, 0)
Step-by-step explanation:
x = -b / 2a
x = 2 / 2(1)
x = 2 / 2
x = 1
y = x^2 - 2x + 1
y = (1)^2 - 2(1) + 1
y = 1 - 2 + 1
y = -1 + 1
y = 0
vértice: (1, 0)
Answer: 5x3 + x2 - 2x + 5
Make sure to combine like terms and watch out for if it’s subtraction or addition.
It would be ft3 because its a cone shape and you multiply the circumference by the height and you’ll get the volume
Answer:
1. 5 hours
2. 4 hours
Reason:
Formula for speed is speed =
, if you want to find time, then take distance / speed, which will equal to 100 / 20 = 5 hours, and the same with 2.
A=A₀

A/A₀=24%=0.24
0.24=

0.000121t=ln(0.24)
t=ln(0.24)/0.000121
=-11794.35
so painting is 11794 years old
