Y = 0.08x2-1.6x+13 and y = 0.08(x-10)2<span>+5 is the correct answer :)</span>
Answer:
2.530 kg
Step-by-step explanation:
230g = 0.23 kg
2.3+0.23=2.53kg
From x=1 to x=5
x=1 is starting time
x=time
y=mx+b
m=slope
b=yintercept
slope=(y2-y1)/(x2-x1)
for points (x1,y1) and (x2,y2)
(1,52000) and (5,116000)
slope=(116000-52000)/(5-1)=64000/4=16000
y=16000x+b
find b
(1,52000)
52000=16000(1)+b
52000=16000+b
minus 16000 from both sides
36000=b
the equation is
y=16000x+36000
at 12 years, x=12
y=16000(x)+36000
y=16000(12)+36000
y=192000+36000
y=228000
sales at year 12 is $228,000
Answer:
A
Step-by-step explanation:
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 9, - 4) and r =
⇒ r² = (
)² = 5
(x + 9)² + (x + 4)² = 5 → A
9 11/12
Explanation:
1 • 3 1/2 • 2 5/6 = 9 11/12
