find <ABC =2x and <CBD=3x-10
Answer:
x = 20
Step-by-step explanation:
m<ABC and m<CBA are complementary angles which means their sum is 90 degrees:
2x + 3x - 10 = 90 add like terms
5x - 10 = 90 add 10 to both sides
5x = 100 divide both sides by 5
x = 20 to find the angles replace x with 20
m<ABC = 40 and
m<CBA = 50
Find d²y / dx², dy / dx for the curve whose equation is x² + y²_3xy_6x + 5y + 2 = 0 at the point (2,3)
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
Solve the system of equations by the substitution method.
( y=2x+1
4y - 5x=13
Type an ordered pair
Step-by-step explanation:
y = 2x + 1
4y - 5x = 13
4(2x + 1) - 5x = 13
8x + 4 - 5x = 13
8x - 5x = 13 - 4
3x = 9
x = 9/3
x = 3
y = 2x + 1
y = 2.3 + 1
y = 6 + 1
y = 7
(x,y) = (3,7)

Answer:
Step-by-step explanation:
Let the number be x
Eight less than a number: x - 8
Product of six and (x - 8) : 6*(x-8)
10 less than 6(x -8) : 6*(x-8) - 10

The diameter of a circle has endpoints S(2, 7) and U(4, -3). What are the coordinates of the center of the circle?
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)

what is the slope of the line represented by the table of values?
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.

Two barrels, that are each cylinders with a radius of 2 feet, are filled with juice. The smaller barrel has a height of 3 feet. The larger barrel has a height of 5 feet. The total volume of the barrels is 100.48 cubic feet
a. What is the volume of the larger barrel?
b. Explain how you can find the volume of the smaller barrel?
step by step solution please thank you
Step-by-step explanation:
a. the volume of the larger barrel =
π.r².h = 3.14 × 2² × 5
= 3.14 × 20
= 62.8 cu. ft
b. the volume of the smaller barrel =
3.14 × 2² × 3
= 3.14 × 12
= 37.68 cu. ft
or it can find the volume by using
the subsraction :
100.48 - 62.8 = 37.68 cu. ft

JJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJ
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.

The ___ of a parabola is the line, along with a point not on the line, which is used to generate a parabola.
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."
