Answer: (x - 3)^2 = -24(y + 3)
Step-by-step explanation:
To find the equation of the parabola in standard form, we can use the formula (x - h)^2 = 4p(y - k), where (h, k) is the vertex and p is the distance between the vertex and the focus.
Given that the directrix is y = 3 and the focus is (3, -3), we can see that the parabola opens downward.
The focus is (h, k + p) = (3, -3) and the directrix is y = k - p = 3. By comparing the y-coordinates, we can find p.
-3 = 3 + p
p = -6
Substituting the values into the formula, we get:
(x - 3)^2 = 4(-6)(y - (-3))
So, the equation of the parabola in standard form is (x - 3)^2 = -24(y + 3).

Answer:
300$
Step-by-step explanation:
If he save 10 for every 50, you just divide. 60/10 = 6. He saved 6 times, if each time he saves he has 50 extra dollars, 6 * 50 = 300 because 6*5 = 30 and there is a extra 0 so 30 and 0 is 300

Answer:
Cross Products Property of Proportions states that the product of the means is equal to the product of extremes.
i,e
Also, in the proportion the first (a) and the last terms(d) are called the extremes, whereas the second(b) and the third terms(c) are called the means.
Given the proportion:
First term = 1
Second term = 2
Third term = 4
Fourth term = 8
By definition;
The product of means =
The product of extremes =
Therefore, the product of both the means and the extremes is, 8
