<span> we have that
standard form of equation for parabola:
(x-h)^2=-4p(y-k)
(h,k) --------->being the (x,y) coordinates of the vertex.
Parabola opens downwards because focus is below vertex on the axis of symmetry.
For given problem:
</span><span>vertex: (-3,2)
axis of symmetry: x=-3
p=distance from vertex to focus on the axis of symmetry=2-(-1)=3
4p=12
Directrix: y=2+p=5
Equation:
(x+3)^2=-12(y-2)
the answer is </span>(x+3)^2=-12(y-2)
Answer:
121 degrees.
Step-by-step explanation:
If the angle is x degrees then its supplement is 180-x degrees.
So we have the equation:
x = 2(180-x) + 3
x = 360 - 2x + 3
3x = 363
x = 121.
-10 is the answer i think
Answer:
A-
YES they are proportional because the answer every time is 5x
B- The x coordinate is growing by one and the y coordinate is growing by 5
C- for 0 t-shirts the y coordinate would be 0 as well, and for 5 shirts it would be 25 (5*5)
Focus on Math-
no it would not because instead of the equation looking like 5x it would look like 5x+4
Enjoy!!
First, you add them all together, and divide them by the number of quantities there are, so:
9+9+8+11+11+12+12+8= <span>80. Then you divide it by 8 (how many numbers there are) to get 10!</span>
