We have to find the focus of the parabola with equation:
In order to find the focus, we first need to convert the equation of parabola to its standard form, as shown below:
Comparing this equation to the similar general equation of parabola, we get:
k = -3
p= 3/4
h = - 2
The focus of the general parabola is located at ( h+p, k)
Using the values, we get:
Focus of the given parabolic satellite =

The weighted weekly mean of t-shirt sales is 5.6.
The total number of weeks reported is the sum of the frequency column.
1+4+7+3 = 15 weeks
The total number of t-shirts sold is calculated as the product of the quantity of t-shirts sold and the number of weeks during which those t-shirts were sold.
2*1 + 4*4 + 6*7 + 8*3 = 2 + 16 + 42 + 24 = 84
The weighted mean, which is the product of the total quantity of t-shirts and the total number of weeks, represents the average number of T-shirts sold every week:
84/15 = 5.6
Response: 5.6
