Find the equation, (f(x) = a(x-h)2+ k), for a parabola containing point (-1,0) and having (-3, 4) as a vertex. What is the stand
kirill115 [55]
(h;\ k)\ -\ \text{the coordinates of the vertex}

\text{therefore we have:}\ f(x)=a(x+3)^2+4

\text{a parabola that passes through the point (-1; 0)}

\text{substitute the coordinates of the poin (-1; 0) to the equation}

(-1;\ 0)\to x=-1;\ y=0\\\\0=a(-1+3)^2+4\\\\0=a(2)^2+4\\\\0=4a+4\ \ \ |-4\\\\4a=-4\ \ \ |:4\\\\a=-1

f(x)=-(x+3)^2+4=-(x^2+2\cdot x\cdot3+3^2)+4=-(x^2+6x+9)+4\\\\=-x^2-6x-9+4=-x^2-6x-5

How do I solve this equation?
umka2103 [35]

Answer:

3 / 512

Step-by-step explanation:

If you want to simplify further, reduce the exponents:

2²/2¹⁰ + 2²/2¹¹

1/2⁸ + 1/2⁹

Find the common denominator and add.

2/2⁹ + 1/2⁹

3/2⁹

3/512

Estimate the circumference of the circle to the nearest hundredth. Use π = 3.14
nekit [7.7K]
The formula for the circumference of a circle is 2πr. r stands for the radius ehich is 1/2 of the diameter (the length from one edge of the circle to another on the inside of the circle). If you are estimating then you will want to change π to three and put that in for pie in the original equation.
