Write the equation for a parabola with a focus at (−4,8)(-4,8)(−4,8)left parenthesis, minus, 4, comma, 8, right parenthesis and a directrix at x=−6x=-6x=−6x, equals, minus, 6.
Given:
The focus of the parabola is at (-4,8).
The directrix is at x=-6.
To find:
The equation of the parabola.
Solution:
The directrix is at x=-6, which is a vertical line. So, the parabola is horizontal.
The equation of a horizontal parabola is
[tex](y-k)^2=4p(x-h)[/tex]
Where, (h,k) is vertex, (h+p,k) is focus and x=h-p.
The focus of the parabola is at (-4,8).
[tex](h+p,k)=(-4,8)[/tex]
[tex]h+p=-4[/tex] ...(i)
[tex]k=8[/tex]
The directrix is at x=-6.
[tex]h-p=-6[/tex] ...(ii)
Adding (i) and (ii), we get
[tex]2h=-10[/tex]
[tex]h=-5[/tex]
Putting h=-5 in (i), we get
[tex]-5+p=-4[/tex]
[tex]p=-4+5[/tex]
[tex]p=1[/tex]
Putting h=-5, k=8 and p=1 in the standard form of the parabola.
[tex](y-8)^2=4(1)(x-(-5))[/tex]
[tex](y-8)^2=4(x+5)[/tex]
Therefore, the required equation of the parabola is [tex](y-8)^2=4(x+5)[/tex].
Answer:
x=[tex]\frac{(y-8)^{2}-20 }4}[/tex]

Which equation does not represent a function?
A y= 4
C y = x – 4
B y = x2 - 4
B
D x2 + y2 = 4
Answer:
D x2 + y2 = 4
Step-by-step explanation:
The following are the functions
y = 4
y = x - 4
y = x^2 - 4
but
x^2 + y^2 = 4 is not a function as there should be minimum one x value with two or more y values
But the above equation does not meet the criteria so this represent non-function
Kara has 4/5 gallon milk, she gives some to her brother. Now she 1/3 gallon of milk. How much milk, in gallons, did she give to her brother
Answer:
7/15 of a gallon
Step-by-step explanation:
Her starting amount 4/5 is equivalent to 12/15. Her ending amount 1/3 is equal to 5/15. So subtract her end amount from her starting amount to find how much she gave to her brother. 12/15 - 5/15 = 7/15.

14 less than the quantity k times 6
(Write it as an algebraic expression)
Answer:
6k-14
Step-by-step explanation:
The algebraic expression for inequality is 14 < 6k.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have the statement
14 less than the quantity k times 6
Now, k times 6 = 6k
and, 14 less than k times 6 can written into mathematical form as
14 < 6k
k > 14/6
k> 7/3.

Suzy is competing in a 651 mile long-distance bicycle race. In the first 3 and 1/2 hours she completed 54 and 1/4 miles. If she plans to ride 7 hours per day, how many days will it take for her to complete the race at that pace?
Answer: 6 days
Step-by-step explanation:
1. Multiply 54 1/4 by 2 (We are multiplying my 2 because 3 1/2 hours is half of 7 hours, so you have to multiply to see how much Suzy rode for 7 hours.
2. Now, divide 651 by the answer you get in step 1 to get your answer (simplify if necessary.)
=> 54 1/4 * 2 = 108 1/2
=> 651 / 108 1/2 = 6

349 + 4.80n
3
135
Step-by-step explanation:
1
For this, use the equation I gave you above to find the costs.
2
First, the cost of the printer will NOT change, for the number of printers Eddie needs to buy does not change, he only needs one. This already helps you figure out that 349 is not a coefficient to the variable, n. However, when it comes to the number of blank shirts Eddie needs to buy, the number of he gets does change, this is the dependent variable that makes the cost vary. Using the equation above, you can plug in any number.
For example, 20.
349 + 4.80(20) = 445
3
For this final part, I just kept using the equation until I got the closest number that is lower than 1000. In this case, 135 got me 997, and 136 was just a few decimals away from 1000, but it was still over.

Find the LCM
The LCM of
0,5 is 5.
Greatest common divisor is the largest number which divides two given numbers say 'a' & 'b'
Now let's say a=0 and b= 5
We know that: anything × 0 =0
Therefore 0÷5=0
In other words 5 is a divisor of 0
and 5 is the largest number which divides 5...
Therefore 5 is the greatest common divisor of of 0 and 5Or gcd(5,0)=5
Common divisors of 0 and 5 = 1,5 [0=1*0 ; 5=1*5] and [0=5*0 ; 5=5*1]

On the first night of Rosh Hashanah, David cuts 5 apple into slices and gives 3/8 of an apple to each of his quests. He has 2 apples left over. How many guests does David have?
Answer:
Number of guests = 8
Step-by-step explanation:
Total apples David cut = 5
Total apples left over = 2
Total apples David gave his guest = Total apples David cut - Total apples left over
= 5 - 2
= 3
Total apples David gave his guest = 3
Each guest gets = 3/8 of an apple
Number of guests = Total apples David gave his guest ÷ share of each guest
Number of guests = 3 ÷ 3/8
= 3 × 8/3
= 8
Number of guests = 8
