The parabola opens towards left, this means the squared term is y with negative coefficient.
The vertex is given to be the point (-1,-3). So, the general equation of the parabola will be like:

where a is any constant.
In the given options, only 1 such equation is available and that is option C.
So the answer to this question is option C
Answer:
Plot the coordinates on a graph and join them to form a triangle. After doing that, you can count the length of each triangular side and find the sum of the 3 sides. That will be your answer.
Answer:
104 ft^2
Step-by-step explanation:
area of rectangle = 8 × 10 = 80
area of triangle = 1/2 × 6 × 8 = 24
∴total area = 104 ft^2
13 spades, 52 cards total
probability of drawing a single spade = 13/52 = 1/4
If we replace that card, then the probability of drawing of drawing a spade is still 1/4 as nothing has changed
Overall, the probability of getting two spades in a row is (1/4)*(1/4) = 1/16
note: the two events are independent because of the replacement happening
---------
The answer as a fraction is 1/16
As a decimal, that would be 0.0625 which converts to 6.25%
Answer: #2. Is 104.18
#3. Is 17 liters left
Step-by-step explanation:how you do number three is you do 30l * 100cm=3000. Then do 3000-1300 which will equal 1700. Then 700=7 liters 1000cm = 10. 10+7=17
