If a parabola’s focus is at (1,1) and directrix is at y = 7, what is the standard form of the equation representing this parabola

Answers

Final answer:

The standard form of the equation of the parabola with focus at (1, 1) and directrix 'y = 7' is (x - 1)² = 12(y - 4). The vertex is found by determining the midpoint between the focus and directrix, and the 'a' value is found by calculating half the distance between the focus and directrix.

Explanation:

To find the standard form of a parabola given the focus and directrix, we'll use the definition of a parabola itself. A parabola is defined as the set of points that are equidistant from a point, known as the focus, and a line, known as the directrix.

The equation representing a parabola is: (x - h)² = 4a(y - k) where (h, k) is the vertex of the parabola and 'a' denotes the distance between the vertex and the focus or the vertex and the directrix.

The mid-point of the focus (1, 1) and the directrix y=7 gives the coordinates of the vertex. So, h = 1 and k = (1+7)/2 = 4.

Now, 'a' is half the distance between the focus and directrix, a = (7-1)/2 = 3.

So, the standard form of the equation is (x - 1)² = 12(y - 4)

You spend $154 to make wooden bookends and plan to sell them online for $8.50 each. You will charge an additional $3.25 per bookend to wrap and ship them. How many bookends must you sell in order for your profit to be at least $600?

Answers

Final answer:

To make a profit of at least $600, the number of bookends that need to be sold is calculated by adding the desired profit to the initial cost, and then dividing this sum by the net revenue per bookend. The result is approximately 144 bookends.

Explanation:

The subject of this problem is Mathematics, specifically a topic within business math called 'breakeven analysis' or 'cost-volume-profit analysis'. It involves calculating the point at which revenue from selling a product equals the costs associated with producing and selling that product. In this case, you have spent $154 to make wooden bookends, and you plan on selling them online for $8.50 each. Additionally, there's a $3.25 fee per bookend for wrapping and shipping, which you charge to your customers. Your goal is to make a profit of at least $600.

To calculate the number of bookends that need to be sold, we first find the net revenue per bookend. This is the selling price minus the shipping cost, which comes out to $8.50 - $3.25 = $5.25 per bookend. The desired profit is added to the cost of making the bookends to find the total required revenue, which is $600 + $154 = $754.

Finally, total required revenue is divided by the net revenue per bookend to find the number of bookends that need to be sold: $754 ÷ $5.25 = approximately 144 bookends (rounded up to the nearest whole bookend since we can't sell a fraction of a bookend). So, in order for your profit to be at least $600, you must sell at least 144 bookends.

ANSWER

We need to rewrite [tex]x+2y=6[/tex], in slope intercept form.

[tex]\Rightarrow 2y=-x+6[/tex],

[tex]\Rightarrow y=-\frac{1}{2}x+3[/tex]


The given equation has a slope of [tex]-\frac{1}{2}[/tex].

ANSWER TO QUESTION 1

We now the write given options also in slope intercept form.


For the first one, we have

[tex]y=-\frac{1}{2}x+5[/tex]


This first equation also has a slope  of [tex]-\frac{1}{2}[/tex].


Hence [tex]y=-\frac{1}{2}x+5[/tex] is parallel to [tex]x+2y=6[/tex].


ANSWER TO QUESTION 2:

The second equation is;

[tex]-2x+y=-4[/tex].


We need to write this one too in slope intercept form.


[tex]y=2x-4[/tex]


This second equation has a slope of 2

Since [tex]2\times -\frac{1}{2}=-1[/tex], the line [tex]-2x+y=-4[/tex]

is perpendicular to [tex]x+2y=6[/tex].



ANSWER TO QUESTION 3

We rewrite the equation [tex]-x+2y=2[/tex] in slope intercept form.


[tex]\Rightarrow 2y=x+2[/tex]


[tex]\Rightarrow y=\frac{1}{2}x+1[/tex]


This equation also has a slope of [tex]\frac{1}{2}[\tex]

since the slope of [tex]-x+2y=2[/tex] is not equal to the slope of [tex]x+2y=6[/tex], and the product of these two slopes [tex]\frac{1}{2} \times - \frac{1}{2} \ne -1[/tex], the two lines are neither parallel nor perpendicular.



QUESTION 4

The given line has equation [tex]x+2y=-2[/tex]. We rewrite this equation in the slope intercept form.

[tex]\Rightarrow 2y=-x-2[/tex]


[tex]\Rightarrow y=-\frac{1}{2}x-1[/tex]


This line has a slope of [tex]-\frac{1}{2}[/tex].


Since this slope is the same as the slope of the given line,


[tex]y=-\frac{1}{2}x-1[/tex] is parallel to  [tex]x+2y=6[/tex].

B. length = 4 cm; width = 9 cm


C. length = 6 cm; width = 7 cm


D. length = 5 cm; width = 5 cm

Answers

A. length = 7 cm; width = 6 cm

Use w to represent width, p as perimeter, and l for length.

l = 2w - 5

2l + 2w = p
2(2w - 5) + 2w = 26
4w - 10 + 2w = 26
6w - 10 = 26
6w = 36
w = 6

The only option with a width of 6 is A.
To check your answer, you can plug it in.
2(6) - 5 = 12 - 5 = 7

Hope this helps.

The correct option is [tex]\boxed{\text{\bf option C}}[/tex] i.e., the length is [tex]6\text{ cm}[/tex] and breadth is [tex]7\text{ cm}[/tex].

Further explanation:

The perimeter of arectangle is calculated as follows:

[tex]\boxed{\text{Perimeter}=2\cdot (l+b)}[/tex]

Here, [tex]l[/tex] is the length and [tex]b[/tex] is the breadth of the rectangle.

Given:

The length of the rectangle is [tex]5\text{ cm}[/tex] less than twice its breadth and the perimeter of the rectangle is [tex]26\text{ cm}[/tex].

Calculation:

Step 1:

First we write the dimensions in the form of variable [tex]x[/tex].

Consider [tex]x[/tex] as the breadth of the rectangle and [tex]y[/tex] as the length of the rectangle.

As per the question the length is [tex]5\text{ cm}[/tex] less than twice its breadth.

Therefore, the length can be expressed in the form of the equation as follows:

[tex]\boxed{y=2x-5}[/tex]  …… (1)

Step 2:

Now, we have to calculate the dimensions of the rectangle.

So, substitute [tex]l=2x-5[/tex] and [tex]b=x[/tex] in the formula of the perimeter of the rectangle to obtain the value of [tex]x[/tex].

[tex]\begin{aligned}\text{Perimeter}&=2\cdot (l+b)\\26&=2\cdot (2x-5+x)\\26&=2\cdot (3x-5)\\26&=6x-10\\6x&=26+10\\6x&=36\\x&=6\end{aligned}[/tex]  

Therefore, the breadth of the rectangle is [tex]6\text{ cm}[/tex].

Now, substitute [tex]x=5[/tex] in the equation (1) to obtain the value of the length.

[tex]\begin{aligned}l&=2x-5\\&=(2\cdot 6)-5\\&=12-5\\&=7\end{aligned}[/tex]

Therefore, the length of the rectangle is [tex]7\text{ cm}[/tex].

Thus, the correct option is [tex]\boxed{\text{\bf option C}}[/tex] i.e., the length is [tex]6\text{ cm}[/tex] and breadth is [tex]7\text{ cm}[/tex].

Why might a person need an emergency fund?

Answers

Answer:

To prepare for the unexpected, it is important to have a reserve fund set aside. Having a reserve fund is important, but it should not always be your first priority. If you have credit card or other debt, pay that off before you start to put your money in a reserve. Credit card debt has a high interest rate, while the money that you will save in your reserve probably won’t gain a lot of interest. Why not? When you choose a place to save your financial reserve, low risk is key. Remember that your financial reserve fund is for emergencies only. If you have an emergency and need to use it, do. Once you are back on your feet, replenish it. Also, once you have saved the amount you need, stop. Your extra savings will serve you better in an investment that yields higher interest.

Which of the following equations could be used to solve the problem?

2x = 67
2x + 1 = 67
2x + 2 = 67
x2 + 1= 67

Answers

Let the smaller integer be x.
The next larger consecutive integer is 1 more than x, so it's x + 1.

x + x + 1 = 67

2x + 1 = 67

Answer is option B.

Answer:

2x + 1 = 67

Let the smaller integer be x.

The next larger consecutive integer is 1 more than x, so it's x + 1.

Alice's backyard is a rectangular piece of property that is twice as long as it is wide. The total area of her yard is 500 m^(2). What is the approximate width of her backyard?

Answers

The approximate width of Alice's backyard is 22.36 in.

Let l be the length of the rectangle and w be the width.
l = 2w
A = 1000 m2 = l*w
1000 m2 = 2w *w
500 m2 = w^2
√500 m2 = √w^2
w = 22.360679775 in or 22.36 in
16 can be approximate width and length which is doubled can be 32, multiply and get 512 which is close to 500m^2, you can also try other close related approximate solutions such as 15 and 30, and more, but closest approximate whole numbers would be *16 as width and 32 as length*

What is the discriminant of the polynomial below 9x2 - 18x + 9?

Answers

The quadratic polynomial is
9x² - 18x + 9

When compared to the standard form ax² + bx + c, the coefficients of the given polynomial are
a = 9, b = -18, c = 9

The discriminant is
D = b² - 4ac = (-18)² - 4(9)(9) = 0

Answer:  0

Answer:

The discriminant of the given polynomial is 0.

Step-by-step explanation:

The discriminant of a quadratic polynomial [tex]p(x)=ax^2+bx+c[/tex] is

[tex]D=b^2-4ac[/tex]

The given expression is

[tex]9x^2-18x+9[/tex]

Here,

[tex]a=9,b=-18,c=9[/tex]

The discriminant of a given polynomial is

[tex]D=(-18)^2-4(9)(9)[/tex]

[tex]D=324-324[/tex]

[tex]D=0[/tex]

Therefore the discriminant of the given polynomial is 0.
