Generally plug 0 in for x and solve for y. whatever y is is your y intercept
Answer: Least common multiple of 4 and 8 is 8
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
<h3>Given : </h3>
- Radius of circle = 7 inches
<h3>To Find : </h3>
- Circumference of circle = ?
<h3>Solution :</h3>
We are given radius, r = 7 inches
We know that :
Circumference = 2πr
⟹ Circumference = 2π × 7 inches
⟹ Circumference = 14π inches
Hence, circumference of circle is 14π inches.
The answer to this question is the last one D
