Well, sometimes it is needed in word form. If someone asks you how much money you need in debt, you might say 1 tenth 4 hundredths. That is why you might need to read 0.203 as 2 tenths 3 thousandths.
Answer:
The vertex of this parabola,
, can be found by completing the square.
Step-by-step explanation:
The goal is to express this parabola in its vertex form:
,
where
,
, and
are constants. Once these three constants were found, it can be concluded that the vertex of this parabola is at
.
The vertex form can be expanded to obtain:
.
Compare that expression with the given equation of this parabola. The constant term, the coefficient for
, and the coefficient for
should all match accordingly. That is:
.
The first equation implies that
is equal to
. Hence, replace the "
" in the second equation with
to eliminate
:
.
.
Similarly, replace the "
" and the "
" in the third equation with
and
, respectively:
.
.
Therefore,
would be equivalent to
. The vertex of this parabola would thus be:
.
Answer:
A = 81
Step-by-step explanation:
When there is a number above the other. You will need to multiply it.
There is a 4 so its 4 times.
-3 x -3 = 9
9 x -3 = -27
-27 x -3 = 81

When you multiply a negative number by a negative number it will be a positive.
If you multiply a positive number by a negative it will be negative.
Let bryce=b jon=j
b=3j
in ten years
b+10+j+10=108
b+j=88
putting value of b
4j=88
j=22
b=66
