I’m pretty sure they all are real numbers-
Answer: Domain: x = All Real Numbers (-∞, ∞)
Range: y ≤ 1 (-∞, 1]
<u>Step-by-step explanation:</u>
y = -2(x - 4)² + 1
The equation is in vertex form → vertex = (4, 1)
The leading coefficient is negative so it will be a max at y = 1
Range: y ≤ 1.
This is a polynomial so there are no restrictions on x.
Domain: x = All Real Numbers
Answer:
The answer is 12.36
Step-by-step explanation:
I just did the assignment and guessed and got them wrong and it said this is the right answer so yeah.
You're welcome!! :D
Answer is 1,2 and 5 (A,B, and E)
Step-by-step explanation:
BE is parallel to CD, therefore, m∠BEC=m∠ECD, therefore mBC=mDE
BE is the diameter, so Arc BE is 180 degree
mBC+mCD+mDE=180
replace mCD with 3mBC, and replace mDE with mBC: mBC+3mBC+mBC=180
5mBC=180
mBC=180/5=36
mCD=3mBC=3*36=108
the inscirbed angle m∠ECD= the measure of arc DE=36
