Using a directrix of y = −2 and a focus of (2, 6), what quadratic function is created?
here are the answers given
\/
f(x) = −one eighth (x − 2)2 − 2
f(x) = one sixteenth (x − 2)2 + 2
f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2
Answers
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
f(x) = 1/16(x -2)^2 +2

Machine A makes 12.75 ounces of popcorn in 3 minutes. Machine B makes 18 ounces of popcorn in 4 minutes.
If each machine makes popcorn for 10 minutes, will there be enough popcorn for eight 9-ounce bags? Explain.
Answers
Answer:
yes if each machine makes popcorn for 10 minutes, there be enough popcorn for eight 9-ounce bags
Step-by-step explanation:
yes because 12.74 x 3.3 = 42.075 and 18 x 2.5 = 45 and when you add those together you get 87. Also 8 9-ounce bags = 72 and that is less then what you have.
Answer:
Yes there will be enough popcorn for eight 9-ounce bags.
Step-by-step explanation:
" eight 9-ounce bags"
Basically
"72 ounces"
"12.75 ounces of popcorn in 3 minutes"
Basically
We need to find out how much popcorn we can make in "One Minute"
12.75÷3=4.25
Now we need to find out how much it can make in "Ten Minutes"
4.25×10=42.5
"18 ounces of popcorn in 4 minutes."
Basically:
We wanna find out how much it can make in "One Minute"
18÷4=4.5
"makes popcorn for 10 minutes"
Basically:
We need to find out how much popcorn it can make in "Ten Minutes"
4.5×10=45
Add (45) and (42.5)
45+42.5=87.5
So yes,there will be enough popcorn for eight 9-ounce bangs due to the fact A and B makes (87.5) ounces of popcorn and thats greater than (72) ounces.

(c) C: $196; B: $194
(d) 270 = 38(h -1) +42; h = 7
(e) Brian charges $270 for working 7 hours
Step-by-step explanation:
Given a table of costs and hours for hiring DJs Celinda and Brian, you want to know their hourly costs, equations for their costs, cost for 5 hours, and hours for a cost of $270.
(a) Hourly costThe cost of an additional hour can be found by subtracting the cost for 1 hour from the cost for 2 hours:
Celinda: $88 -52 = $36 . . . . . cost increase per hour
Brian: $80 -42 = $38 . . . . . . . cost increase per hour
(b) EquationsWe can use the "point-slope form" equation of a line to write the equations for the costs.
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
Rearranging, this is ...
y = m(x -h) +k
Here, the slope is the cost per hour. A suitable point is the first one in the table. The variables 'c' and 'h' are defined for us.
Celinda: c = 36(h -1) +52
Brian: c = 38(h -1) +42
(c) 5 hoursUsing h=5 in each of these equations, we have ...
Celinda: c = 36(5 -1) +52 = 196 . . . . cost for 5 hours
Brian: c = 38(5 -1) +42 = 194 . . . . cost for 5 hours
(d) $270 to Brian
Using the equation for Brian's cost, we simply need to set c=270 to have the equation we need:
270 = 38(h -1) +42 . . . . equation to find hours
The solution to that equation is ...
270 -42 = 38(h -1) . . . . . subtract 42
228/38 = h -1 . . . . . . . . . divide by 38
6 +1 = h = 7 . . . . . . . . . . . add 1. This is the solution.
It would cost $270 to hire Brian for 7 hours.
(e) DescriptionThe solution to the equation for c=270 is h=7. Since h represents the number of hours the DJ is working, this solution tells us Brian will charge $270 for working 7 hours.
__
Additional comment
The two equations can be simplified by eliminating parentheses and combining like terms:
Celinda: c = 36h +16
Brian: c = 38h +4
Parts (d) and (e) work together. The "solution" h=7 doesn't mean anything except in the context of the question it is answering. The question is "how many hours for a charge of $270." The value h=7 means the answer is Brian charges $270 for 7 hours' work.

How fast does each boy walk?
Answers
Answer:
75 miles miles an hour. (First one)
5 mph for the second one.
Step by Step:
1800%2F3 = u + v (1) is the equation for the flight with the wind.
(Here "u" is the airspeed of the airplane with NO wind,
"v" is the wind speed)
1800%2F4 = u - v (2) is the equation for the flight against the wind.
Simplify equations (1) and (2) and write them as a system:
u + v = 600, (1')
u - v = 450. (2')
Now add the two equations (1') and (2'). You will get
2u = 1050 ---> u = 1050%2F2 = 525 miles per hour.
Having this, you can easily determine "v" from (1'):
v = 600 - 525 = 75 miles per hour.
-----------------------------
Second one will be 15 divided by 3 = 5mph

Since a square has 4 equal sides, we can write an eqauation like this:
3x = 5x - 8
Steps to solve:
3x = 5x - 8
~Subtract 5x to both sides
-2x = -8
~Divide -2 to both sides
x = 4
Therefore, each side length is 4 units.
Perimeter formula: 2w + 2l = p
2(4) + 2(4) = p
8 + 8 = p
16 = p
Therefore, the perimeter is equal to 16 units.
