Answer 1
Answer:
157
Step-by-step explanation:
We can already tell that these two figures are congruent due to the angles (if you remember, the "top" and "bottom" angles of trapezoids form 180 degrees). Since we know that these are congruent, we know that GH = BC, and so on. We can then plug in the missing sides by looking at the figure that has the sides. Thus, giving us 157. Hope this wasn't too complicated!

Step-by-step explanation:
The square root of 36 and 361 are 6 and 19 respectively.
What is a perfect square number?
A number when taken square root gives an integer is a perfect square number.
Given, we have to find the square root of 26 and 361.
Now by prime factorization,
36 = 2×18 = 2×3×6 = 2×3×2×3 = 2×2×3×3 = 2²×3².
Now the square root of 2²×3² = √2²×√3² = 2×3 = 6.
The square root of 361 can be found by knowing the square root of 400 which is 20.
Now we'll check if 19² = 361 indeed 19×19 = 361 so, the square root of 361 is 19.

A line passes through (3, –2) and (6, 2). Write an equation for the line in point-slope form.
Rewrite the equation in standard form using integers.
A. y + 2 = 4/3(x – 3); –4x + 3y = –18
B. y – 3 = 4/3(x + 2); –4x + 3y = 17
C. y + 2 = 4/3(x + 3); –4x + 3y = –18
D. y – 2 = 4/3(x – 3); –4x + 3y = 18
Answers
Answer:
A. y + 2 = 4/3(x – 3); –4x + 3y = –18
Step-by-step explanation:
(3, –2) and (6, 2)
First, we must establish slope...
m=(y-y1)/(x-x1)
m=(-2-2)/(3-6)
m=-4/-3
m=4/3
Point slope formula is...
y-y1=m(x-x1)
Let's select either coordinate. I randomly select the first (3, –2)...
y--2=4/3(x-3)
Subtracting a negative number is the same as adding a positive number...
y+2=4/3(x-3)
This corresponds to the first answer.
Standard form...
Ax+By=C
y+2=(4/3)x-4
y=(4/3)x-6
-(4/3)x+y=-6
Multiply both sides by 3...
-4x+3y=-18
This also corresponds to the first answer.
How about the second coordinate, (6, 2)...
y-y1=m(x-x1)
y-2=(4/3)(x-6)
Let's convert it into standard form..
y-2=(4/3)x-8
y=(4/3)x-6
-(4/3)x+y=-6
Multiply both sides by 3...
-4x+3y=-18
FIRST ANSWER
y + 2 = 4/3(x – 3); –4x + 3y = –18

1. -2x^2 - 10x + 100
2. 3x^3 + 9x^2 - 54x
3. x^2 +12x + 20
Answers
1st Question:
Our problem is [tex]-2x^2 - 10x + 100[/tex]
We have a common factor between the three terms, -2. So:
[tex]-2x^2 - 10x + 100[/tex]
[tex]-2(x^2 + 5x -50)[/tex]
We can factor further. What two numbers add up to 5 and multiply to -50? Our answer would be positive 10 and -5. Therefore:
[tex]-2(x^2 + 5x -50)[/tex]
[tex]-2(x +10)(x-5)[/tex]
2nd Question:
The problem is [tex]3x^3 + 9x^2 - 54x[/tex]
Like the first question, we can factor out a constant. In this case, we factor out a 3.
[tex]3x^3 + 9x^2 - 54x[/tex]
[tex]3(x^3 + 3x^2 - 18x)[/tex]
We can also factor out an x.
[tex]3(x^3 + 3x^2 - 18x)[/tex]
[tex]3x(x^2 + 3x - 18)[/tex]
We need to simply further. We can factor the quadratic into (x+6)(x-3).
[tex]3x(x^2 + 3x - 18)[/tex]
[tex]3x(x+6)(x-3)[/tex]
3rd Question:
Our problem is [tex]x^2 +12x + 20[/tex]
We do not have a coefficient, so we should factor the expression straight away. What two numbers add up to 12 and multiply to 20? the numbers 2 and 10. So:
[tex]x^2 +12x + 20[/tex]
[tex](x+2)(x+10)[/tex]

Answer:
Directrix
Step-by-step explanation:
The directrix of a parabola is the line, along with a point not on the line (which is the focus), which is used to generate a parabola. The directrix is parallel either to the x- or y-axis, and is perpedicular to the parabola's axis of symmetry (at x = h).
Therefore, the correct answer is "directrix."
what is the slope of the line represented by the table of values?
Answers
Answer:
The slope is -8/5
Step-by-step explanation:
Slope is the change of y over the change of x.
Two x and y values for example are -7, -2, 9, and 1.
You would set up the expression where you put 9-1 in the numerator and -7-(-2) in the denominator. The answer would be 8/-5.
Thus, the slope is -8/5.

The diameter of a circle has endpoints S(2, 7) and U(4, -3). What are the coordinates of the center of the circle?
Answers
Answer:
Thus the center of the circle is at (3, 2)
Step-by-step explanation:
The center of the circle is also the midpoint of the diameter. Thus we can use the midpoint formulas, as follows:
sum of x coordinates sum of y coordinates
xm = ---------------------------------- and ym = -----------------------------------
2 2
In this case, xm = (2 + 4)/2 = 3 and ym = (7 - 3)/2 = 2
Thus the center of the circle is at (3, 2)
Find the intercepts for the graph of the equation.
-2x-2y = -4
Answers
Answer:
y= -x+2
Step-by-step explanation:
If what they are asking for is slope-intercept format, then you need to isolate the y on one side.
So add -2x to both sides to get, -2y= 2x-4
After that you would divide both sides by -2, and when you do this you are dividing every single term by -2 so you would get,
y= -x+2
that is your slope- intercept formula.
so your slope is m= -1
Answer:
X-intercept: (2,0)
Y-intercept: (0,2)
Step-by-step explanation:
all it's asking for when it says "find the intercepts" is for two points, the one with 0 in the x position, and the one with 0 in the y position of the point (x,y).
These are surprisingly easy! Just plug 0 into x and solve for y. In this case, that gives us (-2)x(0)-2y = -4
Do some algebra and you'll find that y = 2. Since we plugged in 0 for x, that gave us the y-intercept: (0,2). (Remember, the y-intercept is when it intersects the y-axis. All points on the y axis have an X coordinate of 0!)
Now do the same thing but plug 0 in for y.
-2x - (2)x(0) = -4
-2x = -4
x=2
This gives us the x-intercept of (2,0)

Find d²y / dx², dy / dx for the curve whose equation is x² + y²_3xy_6x + 5y + 2 = 0 at the point (2,3)
Answers
I assume you meant to write
x² + y² - 3xy - 6x + 5y + 2 = 0
Taking y = y(x) and differentiating both sides with respect to x with the power, product, and chain rules gives
2x + 2y dy/dx - 3y - 3x dy/dx - 6 + 5 dy/dx = 0
Solve for dy/dx :
2x - 3y - 6 + (2y - 3x + 5) dy/dx = 0
(2y - 3x + 5) dy/dx = 6 - 2x + 3y
dy/dx = (6 - 2x + 3y) / (2y - 3x + 5)
Now differentiate both sides again. Using the quotient and chain rules,
d²y/dx² = ((2y - 3x + 5) (-2 + 3 dy/dx) - (6 - 2x + 3y) (2 dy/dx - 3)) / (2y - 3x + 5)²
Expand and simplify the numerator:
d²y/dx² = (5y + 8 + (3 - 5x) dy/dx) / (2y - 3x + 5)²
Substitute dy/dx and simplify d²y/dx² :
d²y/dx² = (5y + 8 + (3 - 5x) (6 - 2x + 3y) / (2y - 3x + 5)) / (2y - 3x + 5)²
d²y/dx² = ((5y + 8) (2y - 3x + 5) + (3 - 5x) (6 - 2x + 3y)) / (2y - 3x + 5)³
d²y/dx² = (10y² + 50y - 30xy + 10x² - 60x + 58) / (2y - 3x + 5)³
