The following work represents an attempt to find the equation of the parabola which has a vertex of (0, 0) and passes through th

e point (1, 3). Is the work correct? If not, what is the error?
y=a(x-h)^2+k
0=a(0-1)^2+3
-3=a


y=a(x-h)2+k
y=-3(x)^2
y=-3x^2





A.
The equation is correct.
B.
a = –3 should have been a = 9.
C.
0=a(0-1)^2+3 should have been 3=a(1-0)^2+0
D.
-3x^2 should have been 23x^2 + 3.x

Find the rate of change between (-3,6) (0,-3)
marin [14]
<h3>The rate of change between (-3,6) (0,-3) is -3</h3>

<em><u>Solution:</u></em>

Given that,

We have to find the rate of change between (-3,6) (0,-3)

<em><u>The rate of change is given as:</u></em>

Rate\ of\ change = \frac{y_2-y_1}{x_2-x_1}

From given,

(x_1, y_1) = (-3, 6)\\\\(x_2, y_2) = (0, -3)

<em><u>Substituting the values we get,</u></em>

Rate\ of\ change = \frac{-3-6}{0+3}\\\\Rate\ of\ change = \frac{-9}{3}\\\\Rate\ of\ change = -3

Thus rate of change is -3

maks197457 [2]

Answer:

204 ft^2

Step-by-step explanation:

<u>triangle on the left</u>:

A= l x w x 1/2

A = 12 x 5 x 1/2

A = 30 ft^2

<u>triangle on the right</u>:

Same thing

A = 30 ft^2

<u>square in the middle</u>:

A = l x w

A = 12 x 12

A = 144 ft^2

<u>Add them up</u>:

30 + 30 + 144 = 204 ft^2
