Answer:
C
Step-by-step explanation:
Area = π
r means radius
radius = d/2
d = diameter
8 /2 = 4
4 is radius
= 16
^ ( its 4 x 4 ) ^
so then,
Area = 16π
65%
Step-by-step explanation:
Given: Full capacity= 200000 litres
Amount of fuel used during flight= 130000 litres
Now, finding percentage of fuel used on the flight.
∴ Percentage of fuel used=
Solving it, we will get
∴ 65% of fuel capacity been used in this flight.
This problem is incomplete, but I think I know the probable question. Normally, you should have been given the target number of the company's video stores, so that you can replace the value of y and solve for x. Once you solve for x, you add this to year 1990 then you can solve for the year at which you can reach your target value. Suppose y = 3500 stores.
3500 = -264x + 4682
3500 - 4682 = -264x
-1182 = -264x
x = 4.48 years
Technically, that is equal to 4 years. Hence, the year would be 1990+4 = 1994.
Answer:
16. B
17. B
Step-by-step explanation:
16. The intercept form of the parabola is

where
are two x-intercepts.
In your case,

so

To find <em>a</em>, substitute coordinates of the point (-6,-4) parabola is passing through

and

17. The vertex form of the parabola equation is

where <em>(h,k)</em> are the coordinates of the vertex and sign "-" because parabola goes down.
In your case, vertex is (2,3), so

The vertex is 3 units from the focus, then

The equation of the parabola is
