The vertex form of a parabola is expressed as
y = a(x - h)^2 + k
where
a is the leading coefficient
h and k are the horizontal and vertical coordinates of the vertex.
Recall, the general expression for a quadratic equation is
y = ax^2 + bx + c
By comparing with the given equation,
a = - 2, b = 36, c = - 171
The formula for the x coordinate of the vertex is
x = - b/2a
x = - 36/(2 * - 2) = - 36/- 4 = 9
Substituting x = 9 into the equation, we have
y = - 2(9)^2 + 36(9) - 171

For the linear function y = 2/3x + 1 given in this problem, we have that:
a) The slope is of 2/3 and the intercept is of 1.
b) The y-intercept is marked at y = 1 on the y-axis.
c) Using the slope and the intercept, point (3,3) is the second point used to graph the function.
d) The graph of the linear function y = 2/3x + 1 is given at the end of the answer.
How to we graph the linear function?In slope-intercept format, a linear function is defined as follows:
y = mx + b.
For this problem, the function is:
y = 2/3x + b.
Hence:
The slope is of m = 2/3, meaning that when the input x increases by 3, the output y increases by 2.The intercept is of b = 1, meaning that the graph of the function crosses the y-axis(vertical axis), at y = 1.From the intercept, we know that point (0,1), which has x = 0 and y = 1, is part of the graph of the function.
Considering the concept of the slope, of change in y divided by change in x, we have that:
y + 2 = 1 + 2 = 3.x + 3 = 0 + 3 = 3.Hence point (3,3) also belongs to the graph of the given function. Given two points, we can graph a line passing through them, hence the graph is given at the end of the answer, and represents the function y = 2/3x + 1.

-1.9 = 0.5(p +1.7)
Whoever answer first gets brainliest!
Answer:
p=-5.5Step-by-step explanation:
To solve this equation, use the distributive property. Isolate the difference between the numbers from one side of the equation.
Distributive property:
A(B+C)=AB+AC
-1.9 = 0.5(p +1.7)
First, switch sides.
0.5(p+1.7)=-1.9
Divide by 0.5 from both sides.
[tex]\sf{\dfrac{0.5\left(p+1.7\right)}{0.5}=\dfrac{-1.9}{0.5}}[/tex]
Solve.
-1.9/0.5=-3.8
p+1.7=-3.8
Then, you subtract by 1.7 from both sides.
p+1.7-1.7=-3.8-1.7
Solve.
Add or subtract the numbers from left to right.
-3.8-1.7=-5.5
[tex]\rightarrow \boxed{\sf{p=-5.5}}[/tex]
Therefore, the correct answer is p=-5.5.
I hope this helps, let me know if you have any questions.
The value of p on the equation - 1.9 = 0.5(p +1.7) is - 5.5.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, we have to solve for p in the equation - 1.9 = 0.5(p +1.7).
0.5(p + 1.7) = - 1.9
First, we'll distribute the terms.
0.5p + 0.85 = - 1.9.
0.5p = - 1.9 - 0.85.
0.5p = - 2.75.
p = - 2.75/0.5.
p = - 5.5

2sinxcosx/sin^2x+cos^2x-1=1
The simplified equation is sin(2x) = 2
How to determine the value of the trigonometry formula?The trigonometry ratio is given as
2sinxcosx/sin^2x+cos^2x-1= 1
Rewrite the equation of the trigonometry formula properly
So, we have the following equation
2sin(x)cos(x)/sin^2(x)+cos^2(x) -1 = 1
Add 1 to both sides of the equation
So, we have the following equation
2sin(x)cos(x)/sin^2(x)+cos^2(x) = 2
Express 2sin(x)cos(x) as sin(2x)
So, we have the following equation
sin(2x)/sin^2(x)+cos^2(x) = 2
Express sin^2(x)+cos^2(x) as 1
So, we have the following equation
sin(2x)/1 = 2
Multiply both sides by 2
So, we have the following equation
sin(2x) = 2
Hence, the simplified equation of the trigonometry formula is sin(2x) = 2

Given:
1 = 1²
1 + 3 = 2²
1 + 3 + 5 = 3²
1 + 3 + 5 + 7 = 4²
1 + 3 + 5 + 7 + 9 = 5²
1 + 3 + 5 + 7 + 9 + 11 = ___
Let's find the answer and determine the pattern.
Here, we have:
1 + 3 = 4
Now, write the sum as a perfect square:
4 = 2²
For the third equation:
1 + 3 + 5 = 9
Now, write the sum as a perfect square:
9 = 3²
This means the result will be the sum written as a perfect square.
Thus, we have:
1 + 3 + 5 + 7 + 9 + 11 = 36
Now, let's write the sum (36) as a perfect square:

Regarding perfect squares, it is found that:
A negative constant guarantees that the polynomial is not a perfect square.The polynomial with a constant term of -121 is not a perfect square.Perfect squaresPerfect square expressions are formed with the notable products of the square of the sum or the square of the subtraction, as follows:
(a + b)² = a² + 2ab + b² -> square of the sum.(a - b)² = a² - 2ab + b² -> square of the subtraction.The constant term of perfect squares, in both cases, is given by:
b².
Since the number is squared, it will always be a positive value, meaning that a negative constant term guarantees that the polynomial is not a perfect square.
The polynomial with a negative constant in this problem has a constant of -121, hence it is not a perfect square.

A farmer with 1700 m of fancy ones to enclose a rectangular plot the borders on a river if no fence is required along the river what is the largest area that can be enclosed?
Answer
Largest Area that can be enclosed = 361250 m²
Explanation
Let the length of the fencing along the river be L
Let the width of the fencing be W
A sketch of the problem will make it clearer
Perimeter = L + 2W
Perimeter is giving as the total length of the fencing to be 1700 m
L + 2W = 1700
L = 1700 - 2W
The area of the structure is given as
Area = LW
The area is what we want to maximize
Recall, L = 1700 - 2W
Area = LW = (1700 - 2W) × W = 1700W - 2W²
A = 1700W - 2W²
At maximum point, the derivative of any function is zero
Hence,
(dA/dW) = 1700 - 4W
At maximum point,
(dA/dW) = 0
1700 - 4W = 0
4W = 1700
Divide both sides by 4
(4W/4) = (1700/4)
W = 425 m
Recall, L = 1700 - 2W
L == 1700 - 2(425)
L = 1700 - 850
L = 850 m
Maximum Area
= (Length at maximum area) × (Width at maximum area)
= 850 × 425
= 361250 m²

An equation of the line is…..
The linear function passing through the point (2,-9) that is perpendicular to the line y=x+6 is:
y = -x -7.
How to write the equation of perpendicular linear functions?A linear function is modeled according to the following rule:
y = mx + b.
The coefficients of the linear function are as follows:
m is the slope, which is the rate of change of the function.b is the y-intercept, which is the numeric value of the function when x = 0.When two lines are perpendicular, the multiplication of their slopes is of -1.
For this problem, the line is perpendicular to line y = x + 6, which has slope 1, hence:
m = -1.
Then:
y = -x + b.
When x = 2, y = -9, hence we use this to find the intercept b as follows:
-9 = -2 + b
b = -7.
Hence the rule is:
y = -x -7.

We can see that the value of k is -3, then the line is:
y = -3*x + 4
By finding two points of the line, we can graph the line like in the image you can see below.
How to sketch a graph of the line?
Here we have the following linear equation:
y = k*x + 4
We know that this line goes through the point (2, -2), then we can replace these values in the above equation so we get the value of k.
-2 = k*2 + 4
Solving this, we can find the value of k.
-2 - 4 = k*2
-6 = k*2
-6/2 = k = -3
So the value of k, the slope of the line, is k = -3.
Then the line is:
y = -3*x + 4
If we evaluate in x = 1, we get:
y = -3*1 + 4 = 1
So, at this point we know that the line passes through points (1, 1) and (2, -2).
Now we can draw these two points on a coordinate axis, and then connect them with a line. That will be the graph of the linear equation.
