Answer:
B ±sqrt((y-k)/a ) + h= x
Step-by-step explanation:
y=a(x-h)^2+k
Subtract k from each side
y-k = a(x-h)^2+k-k
y-k = a(x-h)^2
Divide by a
(y-k)/a = a(x-h)^2/a
(y-k)/a = (x-h)^2
Take the square root of each side
±sqrt((y-k)/a )= sqrt((x-h)^2)
±sqrt((y-k)/a )= (x-h)
Add h to each side
±sqrt((y-k)/a ) + h= (x-h+h)
±sqrt((y-k)/a ) + h= x
Answer:
-6
Step-by-step explanation:
(-2) * (5) = -10
-10+ 4= -6
The vertical of x is 100 degrees meaning the opposite will be 80 degrees because they always add up to 180 degrees.
28% as a decimal would be 0.28, since it is 28 out of 100, which answers the fraction question : 28/100
