Answer:
Step-by-step explanation:
This is a positive parabola so it opens upwards. The equation for the directrix of this parabola is y = k - p. k is the second number in the vertex of the parabola which is (0, 0), but we need to solve for p.
The form that the parabola is currently in is
so that means that 
. We can use that to solve for p in the formula
so
which simplifies to
which gives us that
p = 2. Now to find the directrix:
y = k - p becomes
y = 0 - 2 so
y = -2, choice A.
Answer:
John has 2 dollars and 46 cents left after his purchases.
Step-by-step explanation:
50 - 17.50 = 32.50
32.50 - 24.99 = 7.51
7.51 - 6.99 = 0.52
0.52 + 5.00 = 5.52
5.52 - 3.06 = 2.46
If x is any given number than I will use the Number five
Your equation will look like this
5^5=25
Answer: The Smith family price for the meal is $36.39
Step-by-step explanation:
The Smith family went out to dinner. • The price of the meal was $29.85.
The sales tax was 6% of the price of the meal.
LEts find sales tax amount
sales tax amount = price of meal * sales tax 6%(0.06)
= 29.85 * 0.06 = 1.791
sales tax amount = 1.791
Price of the mean with sales tax = 29.85 + 1.791= 31.641
The tip was 15% of the meal and the sales tax
now we find out tip amount for 31.641
15 % is 15/ 100 = 0.15
Tip amount = 31.641 * 0.15 = 4.74615
Now we add the top amount with 31.641
31.641+ 4.74615=36.38715
the Smith family price for the meal = $36.39
