What is the focus of the parabola given by the equation y = x2 − 2x − 3?
y = x2 − 2x − 3
y = x2 − 2x − 3 -1 +1y = (x - 1)^2 - 4 h = 1 and k = - 4 and a = 1
Vertex (a, k) so it is (1,-4)
Now focus is
(1, -4 + 1/4) = (1,-3 3/4)
or
(1,-3.75)
-2/(a+b)
Explanation: you are dividing negative two by the sum of a and b so you would put a+b in parentheses as the denominator and then put -2 as the numerator
Answer:
1 hour and 30 minutes.
Here's how I did it:
960/3 = 220
220 = 30 minutes
220 = 30 minutes x 3 = 960
30x3=90
90 has to be converted into minutes and hours
so 90 = 1:30
Answer:
SAS
Step-by-step explanation:
GIVEN: BD=AC
angle BAD= angle ADC because they are both 90 degrees.
AB=DC because both are right triangles
