Using the equation of an parabola, it is found that the value of p is 0.5.
The equation of a parabola that is concave to the left or to the right, that is, that has directrix y = k, and vertex (h,k), is given by:
[tex](y - k)^2 = 4p(x - h)[/tex]
The focus is at: (h, k + p).
The directrix is at: y = k - p
For this problem, we have that:
Focus at (0,3), thus [tex]k + p = 3 \rightarrow k = 3 - p[/tex].Directrix at y = 4, thus [tex]k - p = 4[/tex]Since [tex]k = 3 - p[/tex]:
[tex]3 - p - p = 4[/tex]
[tex]2p = 1[/tex]
[tex]p = \frac{1}{2}[/tex]
[tex]p = 0.5[/tex]
The value of p is 0.5.

line 1: y= 2x - 3
line 2: 2x + y - 3 = 0
line 3: y= 5x + 11
line 4: 2x - y = 10
line 5: y= 1/2x - 5
a) which line has the greatest slope? explain ur answer.
b) which lines are parallel? show workings and explain
c) which lines are perpendicular? show workings and explain.
d) at which point does line 3 cross the y-axis?
Answer:
a) line 3 because the coefficient of the term 5x, the slope is the greatest slope.
b) line 1 and 4 are parallel because they have the same slope: 2
c) line 1 with line 2 and line 4 with line 2 are perpendicular lines because their slopes are reciprocals negative.
d) line three crosses the y line at point 11
Step-by-step explanation:
Line 1. y = 2x - 3
Line 2: y = -2x + 3
Line 3: y = 5x + 11
Line 4: y = 2x - 10

From the top of a 200 foot lighthouse, the angle of depression to a ship on the ocean is 23 degrees.
How far is the ship from the base of the lighthouse?
I know I did it right by the key says its wrong. Please provide steps
the ship is 472 m from the lighthouse
Step-by-step explanation:
from the question, we can know ∠OAS = 90°-23° =67° and AO = 200m
OS = A0 • tan 67°
= 200 m • 236°
= 472 m

I need help figuring out the answers to these kinda poorly worded questions
=======================================================
Explanation:
Let x be the unknown positive integer.
The square roots of x are [tex]\sqrt{x}[/tex] and [tex]-\sqrt{x}[/tex], representing the positive and negative square roots respectively.
Taking the difference of those means we subtract:
[tex]\text{PositiveRoot}-\text{NegativeRoot} = \sqrt{x} - (-\sqrt{x}) = \sqrt{x}+\sqrt{x} = 2\sqrt{x}[/tex]
Set that equal to 40 and solve for x
[tex]2\sqrt{x} = 40\\\\\sqrt{x} = 40/2\\\\\sqrt{x} = 20\\\\x = 20^2\\\\x = 400[/tex]
Therefore, the integer we're after is 400.
The positive square root of such is [tex]\sqrt{x} = \sqrt{400} = \sqrt{20^2} = 20[/tex]
And the negative square root is [tex]-\sqrt{x} = -\sqrt{400} = -\sqrt{20^2} = -20[/tex]
The difference of which is:
(Positive Root) - (Negative Root) = 20-(-20) = 20+20 = 40
This helps confirm the answers.

PLSSS HELP WILL MARK FIRST RIGHT ANSWER BRAINLIEST!!!
Answer:
x= -11
Step-by-step explanation:
Rearrange terms
[tex]-1=\frac{5+x}{6} into -1=\frac{x+5}{6}[/tex]
Multiply all terms by the same value to eliminate fraction denominators
[tex]-1=\frac{x+5}{6} \\6(1)=6(\frac{x+5}{6} )[/tex]
Cancel multiplied terms that are in the denominator
[tex]6(-1)=6 (\frac{x+5}{6} )6(-1)=x+5[/tex]
Multiply the numbers
[tex]6(-1)=x+5\\-6=x+5[/tex]
Subtract 5 from both sides of the equation
[tex]-6=x+5\\-6-5=x+5-5[/tex]
Simplify
Subtract the numbers

Stanley's weekly allowance is $5. He can also earn $2 each time he walks the family dog. Write an equation that shows how the amount of money Stanley gets in a week, y, depends on the number of times he walks the dog, x.
Answer:
y = 2x + 5
Step-by-step explanation:
Since he earns $2 for every time he walks the dog, we multiply x by 2
He already starts with $5, so just add 5 to the equation to find y

hope this helps! :)
Let's separate this out and multiply the coefficients first, then the variables.
2 1/3 = 7/3
7/3 * -3/7 = -1
(a^2)(x)(a^3)(x^2)
When we multiply terms with exponents, we ADD the exponents.
(a^5)(x^3)
Answer: (-1)(a^5)(x^3)

A company offers you a salary of $2,000 per month plus a signing bonus of $10,000. What is the yearly salary rate? PLEASE HELP!!!!
Since yearly, without the bonus, you would make a certain amount by multiplying $2,000 to a year, which is 12 months.
2000 × 12 = 24,000 a year.
That would be $24,000 a year.
Next, we can add 10,000 to the amount, since you are not getting paid that much for a year. It is just a "...plus...", a bonus.
24,000 + 10,000 = 34000
Therefore, the yearly salary rate will be $34,000 a year.
