Answer:
see below
Step-by-step explanation:
The leading minus sign tells you the graph opens downward. (x-3) in the squared term tells you the x-coordinate of the vertex is x=3. The graph that matches these characteristics is shown below.
Answer:
X = 12000
Step-by-step explanation:
1200 is 10% of X
Writing in equation form, we get,

Answer:
Tenths
Step-by-step explanation:
After the decimal there is each a place value.
The first number that comes after a decimal is the ones place, next is the tenth, and hundredths, and so on.
Distance = rate * time (I will abbreviate as d = rt)
d = rt, so r = d/t
r = 20mi/24min
= 0.833333 mi/min.
d = rt again for the new time
d = 0.8333333 mi/min * 6 min = 5 miles
Sum of aritmetic sqeuqnece is
(n/2)(a1+an)
a1=first term
an=nth term
n=how many terms
so we gots
a1=3(1)-4=-1
a18=50
n=18
(18/2)(-1+50)
(9)(49)
441
other one
a1(1-r^(n+1))/(1-r)
2(1-2^(15+1))/(1-(1/4))
about 2 and 2/3, so closer to 3
