10 less than the product of six and eight less than a number
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
6*(x-8) - 10

Julius' answer is incorrect
What did Julius do wrong? Select the correct answer to complete the statement.
Julius multiplied 25 by ? and then multiplied 25 by 8 correctly. He added the two
partial products ?
Check
Next
What Julius did wrong is that, he added the partial products incorrectly
Julius product is given as:
2 5
1 8
-----
250
200
-----
550
The above product can be represented as (as given on Julius solution):
[tex]25 \times 18 = 250 + 200[/tex]
[tex]25 \times 18 = 550[/tex]
The actual solution using partial products
We have:
[tex]25 \times 18 = 25 \times (10 + 8)[/tex]
Expand
[tex]25 \times 18 = 250 + 200[/tex]
[tex]25 \times 18 = 450[/tex]
By comparing, we can conclude that:
Julius multiplied 25 by 10 and 25 by 8 correctly, but he added the partial products incorrectly

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

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)

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."
In a direct variation, y=12 when x=3. Write a direct variation equation that shows the relationship between x and y.

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

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

Answer:
f(5) is greater and it is 1.7778 times greater than g(5)
Step-by-step explanation:
f(5) = 3(5)^2 +5
f(5) = 3(25) + 5
f(5) = 75 + 5
f(5) = 80
g(5) = 11(5) - 10
g(5) = 55 - 10
g(5) = 45
