Use our brains and what we know
f(x)=a(x-h)²+k
vetex is (h,k)
and a is te leading coefient
if directix is below the focus, then it opens up and a is positive
if directix is above focus, then it opens down and a is negaitve
vertex is in between directix and focus
so
(3,-1) and y=1
-1<1
so directix is above
a is negative
directly in between
distance from -1 to 1 is 2
2/2=1
1 above (3,-1) is (3,0)
vertex is (3,0)
y=a(x-3)²+0
y=a(x-3)²
the only option with a negative 'a' value is B
answer is B
Hi!
We know that there are three measures and each has a different amount of notes. To find the total we add them all up.
8+16+4=28.
There were 28 total notes played in the song.
I hope I helped you!
Have a wonderful day!
Given that vsr=8x+18, the value of x that that will make r is perpendicular to vs can be obtained as follows;
let:
vsr=8x+18=90
solving for x we get:
8x+18=90
8x=90-18
8x=72
x=72/8
x=9
The answer is x=9
It would decrease it as they usually have offers with coupons.
Answer:
$62.00
A school administrator bought 6 desk sets
that consists of one table and one chair.
He paid for each chair = $48.50
Cost of all 6 chairs = 48.50 × 6 = $291.00
He paid total for the 6 sets = $663.00
To get cost of 6 tables we subtract cost of
6 chairs from total payment of 6 desk sets.
Cost of all 6 tables =$663 - $291 =
$372.00
Therefore, cost of each table = $372 ÷ 6 =
$62.00
The cost of each table is $62.00
