Answer:
32 and 33
Step-by-step explanation:
so , 65-33= 32
32+33 is 65.
A=1/2(h)(3/4h)
A=3/8h²
h²=8/3(A)
h=√8A/3
☺☺☺☺
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
Answer:
20 : 28
5 : 7 = 20 : 28. And 7 is a fourth of 28.
You can just pick any 5 digit decimal and multiply it with any 4 digit decimal to check.
You will see that it has 9 digits after the decimal.
