the shape of the telescope is said to be a parabola. In this case, t<span>he general form which we will pattern our equation is y- k= 4a(x – h)^2
(h,k) or vertex = (0,0)
y = 4ax^2
We substitute x = 320/2 = 160, y = 46
46 = 4a (160)^2
46 = 4a (25600)
4a = 23/12800
hence the equation is </span>y = (<span>23/12800)</span>x^2
Answer:
The answer to this equation is x=2.
Step-by-step explanation:
9x-10=3x +9
You add 10 to both sides
9x-10+10 =3x+2+10
Simplify
9x+ 3x+12
Subract 3x from both sides
9x-3x=3x+12-3x
Simplify
6x=12
Divide both sides by 6
6x/6 = 12/6
<u>Your answer: x=2 </u>

Answer:
Answer: A) 15
A natural number is basically a counting number {1, 2, 3, 4, 5, ...} so any positive whole number. That is why 15 is the answer. Choices B and D are fractional values, so we can rule them out. We can rule out choice C because this value is negative.
