Answer:
(0,3) and (π,3)
Step-by-step explanation:
The period of a sine graph is the magnitude of the interval over which the graph completes a full cycle.
From the graph, the sine function completed one full cycle in [0,π]
The period is π.
The midline us y=3.
Two points on the midline that are separated by a distance of π are (0,3) and (π,3)
16,400 x (1 + 0.051)^20 =
16400 x (1.051)^20 =
16400 x 2.70429659 =
$44,350.46
Answer:
very easy
Step-by-step explanation:
4(2/3) = 14/3
14/3 ÷ 7
14/3 x 1/7
14/21
2/3
11.9
i just got it right on a quiz so yeah
If we were to foil
after experieence
we know
ax²+bx+c=0
and
in form
(ax+b)(cx+d)=0
if we expand it, we get
acx²+bcx+adx+bd=0
or
(ac)x²+(bc+ad)x+(bd)=0
compare to
ax²+bx+c=0
we notice that the middle terms (x terms) are
b=(bc+ad)
so
in form
(2x-1)(1x+5)
b=bc+ad=(-1*1+2*5)=-1+10=9
b=9
or you could just expand it
