Complete the general form equation of the parabola that passes through (4, -11) with vertex at : (2, -3).

fomenos

Answer:

Step-by-step explanation:

You're given a coordinate in the form of (x, y) and you're also given the vertex in the form of (h, k). We will use those in the vertex form of the equation

$y=a(x-h)^2+k$ and solve for a. Filling in:

$-11=a(4-2)^2-3$ which simplifies a bit to

$-11=a(2)^2-3$ and a bit more to

$-11=4a-3$ . Add 3 to both sides to get

-8 = 4a so

a = -2

The equation, then, is

$y=-2(x-2)^2-3$

Use the function below to find F(2) F(x)=1/3•4^x A.)2 B.)4 C.)8/3 D.)16/3

inna [77]

Answer:

Step-by-step explanation:

The function $F(x) = \frac{1}{3}*4^x$ has value F(2) when x = 2 is substituted.

$F(x) = \frac{1}{3}*4^x\\F(2) = \frac{1}{3}*4^2\\F(2) = \frac{1}{3}*16\\F(2) = \frac{16}{3}$

Solve for w: -4u-w = u+6w

wlad13 [49]

Answer:

Step-by-step explanation:

-4u - w = u + 6w

-4u = u + 7w (Add w to both sides)

-5u = 7w (Subtract u from both sides)

w = $-\frac{5u}{7}$ (Divide both sides by 7)
