What you do is move the equation around so the 12 -4.5x would now turn into y=-4.5x+12
The square root of pi is 1.77245385091 :)
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:
Step-by-step explanation: integers are whole numbers , it could be positive or negative.
Therefore 71 and - 9 are integers
- 42/7 written in this form is a Rational number , but when divided , it will give -6 which is an integer.
-94 . 8 is not an integer
19/ 5 is not an integer, it is a rational number
Answer:
QR is tangent to circle P at point Q
=> RQP = 90 deg
=> RQP is right triangle.
=> Applying Pythagorean theorem for right triangle RQP:
QP^2 + QR^2 = RP^2
=>4^2 + QR^2 = RP^2
=> Option A is correct.
(4^2 + (4*
)^2 = 16 + 48 = 64 = 8^2)
=> Option C is correct.
(4^2 + 3^2 = 16 + 9 = 25 = 5^2)
=> Option D is correct
(4^2 + 2^2 = 16 + 4 = 20 = (2
)^2)
Hope this helps!
