Answer:
x^2 - 2x + 5 = 0.
Step-by-step explanation:
The (0, 5) is the point where the parabola passes through the y axis (where x = 0), so we can write the equation as
y = ax^2 + bx + 5 where a and b are constants to be found.
Also, since (1, 4) and (2, 5) are points on the curve, substituting, we have the system:
a(1)^2 + 1b + 5 = 4
a(2)^2 + 2b + 5 = 5
Simplify these 2 equations:
a + b = -1 .................(1)
4a + 2b = 0..................(2)
Multiply the first equation by -2:
-2a - 2b = 2 .................(3)
Add (2) + (3):
2a = 2
a = 1.
Substitute a = 1 into (2):-
4*1 + 2b = 0
2b = -4
b = -2.
Hi! Your answer is below!
Answer- Here's a simple model:

This is just something to help you out! I found it while searching on the internet! I have no Idea what the answer is, but in my defense, I think it's going to be choice 3!
Srry if I couldn't help! Glad if I could help!</span></span>
Answer:
<em>Okay, so what I think you mean to ask what the scale factor between the model and actual building</em> is, so i crunched the numbers. if 1 in equaled 8 feet and the actual thing was 64 ft, then we can just say that 64 divided by 12 is 5.3, so the model could be
5.3 ft. is the size of the model
BUT
you said how many feet are they apart so in inches its 705, in ft its 58.75
Step-by-step explanation:
a foot is 12 in.
64/12 is 5.3
64 ft is 768 inches, and 5.3 is 63.
768-63 = 705.
there are 705 inches in difference, in feet its 58.75
Answer:
5 x 2 -3 = 7
Step-by-step explanation:
i mean.... thats all
Answer:
, D
Step-by-step explanation:
3 if x is greater than or equal to 1 is nothing. That leaves us with 
if x<1. If you substitute in 1 for x, you get 3, but of course that isn't possible, so the range is , which is D.
