What is the equation of the graph below? A graph shows a parabola that opens up and crosses the x axis at negative two and negative four. y = − (x − 3)2 + 1 y = − (x + 3)2 + 1 y = (x − 3)2 − 1 y = (x + 3)2 − 1
Answer:
[tex]y=(x+3)^{2} -1[/tex]
Step-by-step explanation:
General equation of a parabola that opens up is [tex]y=a(x-h)^{2} +k[/tex] , a>0
So equation becomes [tex]y=(x-h)^{2} +k[/tex] which implies option A and option B can never be true for this parabola.
Also this parabola's vertex lies in 3rd quadrant where coordinates of both x and y will be negative.
So, the equation of parabola will be of the form [tex]y=(x+h)^{2} - k[/tex]
Hence, option 4 that is [tex]y=(x+3)^{2} -1[/tex] is correct.
The correct equation of the graph is: x² + 6x - 35y + 8 = 0.
The equation of the graph shown, which is a parabola that opens upwards and crosses the x-axis at -2 and -4, can be determined by examining its key features.
The fact that the parabola opens upward indicates that the coefficient of the squared term (x²) in the equation must be positive.
The parabola crosses the x-axis at -2 and -4. This means that the two x-intercepts are -2 and -4.
Putting this information together, we can form the equation:
y = a * (x - r1) * (x - r2)
where 'a' is a positive constant (coefficient of x²), and r1 and r2 are the x-intercepts.
Since the x-intercepts are -2 and -4, the equation becomes:
y = a * (x - (-2)) * (x - (-4))
y = a * (x + 2) * (x + 4)
Now, let's find the value of 'a.' We are given that the parabola passes through the point (3, 1). We can substitute these coordinates into the equation to find 'a':
1 = a * (3 + 2) * (3 + 4)
1 = a * 5 * 7
a = 1 / (5 * 7)
a = 1 / 35
Now that we have the value of 'a,' we can finalize the equation:
y = (1/35) * (x + 2) * (x + 4)
Expanding the equation:
y = (1/35) * (x² + 6x + 8)
To put the equation in standard form, we can multiply both sides by 35 to eliminate the fraction:
35y = x^2 + 6x + 8
Finally, rearrange to get the equation in standard form:
x² + 6x - 35y + 8 = 0
So, the correct equation of the graph is: x² + 6x - 35y + 8 = 0.

What is an equation of the line that is perpendicular to y=−23x+5 and passes through the point (2, 11) ?
Answer:
The equation would be y = 1/23x - 251/23
Step-by-step explanation:
To start, you need to locate the slope of the first equation. Since the slope is the coefficient of x, we know it to be -23. Now, the perpendicular slope is the opposite and reciprocal of that, which makes the new slope 1/23.
Now that we have this, we can use the point and the slope in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 11 = 1/23(x - 2)
y - 11 = 1/23x - 2/23
y = 1/23x - 251/23

Kelley ate 3/5 of her brownies on Monday and 6/8 of her brownies Tuesday. If Kelley originally had 2 brownies, what fraction brownie is left over? Simplifty your answer
Answer:
[tex]\frac{13}{20}[/tex]
Step-by-step explanation:
First, we need to add the two fractions together. To do this we need to make the denominator a factor of both 8 and 5. Easy way to do this is to multiply each fraction by the denominator of the other fraction:
[tex]\frac{3}{5} * 8 = \frac{24}{40}[/tex]
[tex]\frac{6}{8} * 5 = \frac{30}{40}[/tex]
[tex]\frac{24}{40} + \frac{30}{40} = \frac{54}{40}[/tex]
We can also show 2 brownies as [tex]\frac{2}{1}[/tex] or [tex]\frac{80}{40}[/tex]
Now we can subtract the two:
[tex]\frac{80}{40} - \frac{54}{40} = \frac{26}{40}[/tex]
Simplify the fraction down by dividing by two:
[tex]\frac{13}{20}[/tex]
Which is the fraction of brownie left!

After m months the height of a plant is 10 + 3m millimeters. How tall is the plant after 8 months? Three years?
Answer:
A. 34 millimeters.
B. 118 millimeters.
Step-by-step explanation:
We have been given that after m months the height of a plant is [tex]10+3m[/tex] millimeters.
To find the height of plant after 8 months we will substitute m=8 in our given expression.
[tex]\text{The height of plant after 8 months}=10+3\times 8[/tex]
[tex]\text{The height of plant after 8 months}=10+24[/tex]
[tex]\text{The height of plant after 8 months}=34[/tex]
Therefore, the height of plant after 8 months will be 34 millimeters.
B. Now let us find height of plant after 3 years.
First of all we will convert 3 years into months by multiplying 3 by 12 as 1 year equals to 12 months.
[tex]\text{3 years}=3*12\text{ months}=36\text{ months}[/tex]
Now let us substitute m=36 in our given expression.
[tex]\text{The height of plant after 36 months}=10+3\times 36[/tex]
[tex]\text{The height of plant after 36 months}=10+108[/tex]
[tex]\text{The height of plant after 36 months}=118[/tex]
Therefore, the height of plant after 3 years (36 months) will be 118 millimeters.

By which matrix should you multiply vector [1 3] to rotate it 180°?
Answer:
B
Step-by-step explanation:
Rotation 180° is accomplished by negating both the x- and y-coordinates. That is, you multiply each of them by -1. You want the opposite of the identity matrix, so matrix B.
We have that the Rotation of matrix [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] will be rotated 180 degree if [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] is multiplied by [tex]\begin{pmatrix}-1 & 0\\0 & -1\end{pmatrix}[/tex]
Option D is correct
From the Question we are given
[tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex]
it is important to note that the rotation of the identity matrix [tex]\begin{pmatrix}1 & 0\\0 & 1\end{pmatrix}[/tex] rotating across the Cartesian co-ordinate is a [tex]180 \textdegree[/tex] is going to give a matrix [tex]\begin{pmatrix}-1 & 0\\0 & -1\end{pmatrix}[/tex]
Therefore
The Rotation of matrix [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] will be rotated 180 degree if [tex]Matrix =\begin{pmatrix}1 \\3\end{pmatrix}[/tex] is multiplied by [tex]\begin{pmatrix}-1 & 0\\0 & -1\end{pmatrix}[/tex]

A polynomial function has -5√3i as a root. Which of the following must also be a root of the function?
-5-√3i
-5+√3i
5-√3i
5+√3i
Answer:
-5+√3i is the given root so -5-√3i must be the other root
Step-by-step explanation:
We know that complex roots must come in pairs. The pairs are complex conjugates. (a+bi) and (a-bi)
You are missing a sign between -5 and the square root
So if - 5+ sqrt(3) i is a root, then -5 - sqrt(3) i must be a root

A rectangular field is 115 meters long and 70 meters wide. Give the length and width of another rectangular field that has the same perimeter but a larger area
To find a rectangular field with the same perimeter but a larger area than the original field (115m x 70m), we should search for dimensions that sum up to half of the perimeter (185m) and form a shape closer to a square. An example would be a field measuring 92.5m by 92.5m, which has the same 370m perimeter but a larger area.
Explanation:You have asked about the length and width of another rectangular field that has the same perimeter but a larger area than a field measuring 115 meters in length and 70 meters in width. To find the dimensions of such a field, we must first calculate the perimeter of the original field.
The formula for the perimeter (P) of a rectangle is P = 2(length + width). Plugging in the given dimensions, we get P = 2(115m + 70m) = 2(185m) = 370 meters. Now we need to find dimensions that add up to half this perimeter, since length + width = P/2, which is 185 meters, but form a rectangle with a larger area.
Area (A) is calculated by the formula A = length x width. To maximize the area for a given perimeter, the rectangle should be closer to a square because a square has the largest area for a given perimeter. Hence, the dimensions we are looking for should be closer to each other compared to the original dimensions of 115m x 70m.
An example of dimensions that meet these criteria would be 92.5 meters by 92.5 meters. Although this results in a square, it fulfills the condition of having the same perimeter (since 2(92.5m + 92.5m) = 370m) but a larger area (92.5m x 92.5m = 8556.25 square meters) than the original rectangular field (115m x 70m = 8050 square meters).

Which equation represents a line that has a slope of 4 and passes through the point (3,-8)?
Answer:
The equation of this line would be y + 8 = 4(x - 3)
Step-by-step explanation:
In order to get this we can start with the base form of point-slope.
y - y1 = m(x - x1)
Now that we've got this, we can plug in the slope for m. We can also plug in the point for (x1, y1).
y + 8 = 4(x - 3)

The exponential decay graph shows the expected depreciation for a new boat, selling for $3500, over 10 years.
Write an exponential function for the graph. Use the function to find the value of the boat after 9.5 years.
Answer:
y = 3500(3/7 ) ^ 1/3
y = 239.23
Step-by-step explanation:
For exponential decay
y =a b^x
a = 3500
b<1
We can use the point (3, 1500)
1500 = 3500 * b^3
Divide each by 3500
1500/3500 = 3500/3500 b^3
15/35 = b^3
3/7 = b^3
Take the cube root of each side
(3/7) ^ 1/3 = b^3 ^ 1/3
b = (3/7 ) ^ 1/3
The function is
y = 3500 (3/7) ^ 1/3 x
We want to find y when x=9.5
y = 3500 (3/7) ^ (9.5 /3)
y = 3500 ( 3/7) ^ 3. 166666666
y = 3500 (.06835)
y = 239.23
Lets check a point and see if we a close
(7,500)
y = 3500 (3/7)^ (1/3*7)
y = 3500 (3/7) ^ (7/3)
y = 484.68
That is pretty close. We do not know the exact value since we are reading from a graph.

Lucy and Ethel’s favorite store was having a sale. Lucy bought 10 shirts and 4 pairs of jeans and spent $280. Sabrina bought 12 shirts and 5 pairs of jeans and spent $344.
Assuming that each shirt was the same price, and each pair of jeans was the same price, how much did each shirt and each pair of jeans cost? Write a system of equations to represent this situation. Then solve for the solution using the elimination method.
Final answer:
By defining variables for the prices and setting up a system of equations, we determine that each shirt costs $12 and each pair of jeans costs $40 after solving the system using the elimination method.
Explanation:
The subject of this question is a problem involving systems of equations, which falls under the category of Mathematics. We are given a scenario where Lucy and Ethel are buying clothing at the same prices, but in different quantities and we need to determine the cost of each item. First, let's define variables: let s be the price of a shirt and j be the price of a pair of jeans. We then have two equations based on the purchases:
10s + 4j = $280 (Lucy's purchase)12s + 5j = $344 (Sabrina's purchase)To solve these equations using the elimination method, we will multiply the first equation by 5 and the second by 4 to eliminate the jeans variable:
50s + 20j = $140048s + 20j = $1376Subtract the second equation from the first:
2s = $24Now divide by 2 to find the price of one shirt:
s = $12 (price of a shirt)We can substitute s = $12 into the first original equation to find the price of a pair of jeans:
10(12) + 4j = $280120 + 4j = $2804j = $160j = $40 (price of a pair of jeans)is -4.2778 rational or irrational?

Refer to the table of long distance rates. Write an expression that can be used to find the cost of an n-minute long distance call, where n is at least 5 minutes.
Answer:
a(n) = 0.55 + (n -5)0.07
Step-by-step explanation:
The cost goes up $0.07 for each additional minute, so that is the slope of the linear function. In point-slope form the equation can be written ...
... a(n) - 0.55 = 0.07(n -5)
adding 0.55, and rearranging slightly, this becomes ...
... a(n) = 0.55 +(n -5)0.07
