one factor of 8x^3+1 is 2x+1 The other factor is?
Answers
So that you have 2^3*x^3+1
Multiply the terms with equal exponents by multiply the bases (1 is basically the same as 1^3)
So that it becomes (2x)^3+1^3
Then, using a^3+b^3 equals (a+b)(a^2-2ab+b^2), factor the expression so that it becomes
(2x+1)((2x)^2-2x+1^2)
Expand the second bracket
So the two factors are (2x+1) and (4x^2-2x+1)

Mr Avalon's cousin's Kurt and rod started their own business curtain rods curtain rods they sell curtain rods for $5 each they rent a store in the mall for their business for $2,500 per month how many curtain rods must they sell to earn a profit of$ 3750?
Answers
Answer:34.3 N and 15.7 N
Explanation:
= force on the left end of the rod
= force on the right end of the rod
M = mass of Halloween decoration = 3 kg
= weight of the Halloween decoration = Mg = 3 x 9.8 = 29.4 N
m = mass of rod = 2.1 kg
= weight of the rod = mg = 2.1 x 9.8 = 20.6 N
From the force diagram, using equilibrium of torque about A
(AB) + (AC) = (AD)
(29.4) (21) + (20.6) (57) = (114)
= 15.7 N
Using equilibrium of force along the vertical direction
+ = +
15.7 + = 29.4 + 20.6
= 34.3 N

What is the equation of a line that is perpendicular to -x + 2y =4 and passes through the point (-2, 1)
Answers
Answer:
y = -2x - 3
Step-by-step explanation:
-solve for y: y = 1/2x + 2
-perpendicular equals opposite slope: -2
-plug in the point: (1) = -2(-2) + b
1 = 4 + b
b = -3
put it all together: y = -2x - 3
A student concluded that 0.5(6x+4) = 3x+4 has no solution. Which statement BEST describes the student's conclusion? A.) The conclusion is correct because the coefficient before the variable is equivalent. B.) The conclusion is incorrect because there is exactly one solution to the equation. C.)The conclusion is correct because, when simplified, both sides of the equation are equivalent. D.)The conclusion is incorrect because there are two solutions to the equation.
Answers
Answer:
The conclusion is correct because the coefficient before the variable is equivalent.
Step-by-step explanation:
The given equation is :
0.5(6x+4) = 3x+4
First, we will solve the equation.
3x+2=3x+4
A student concluded that the above equation has no solution. The conclusion is correct because the coefficient before the variable is equivalent. Hence, the correct option is (a).
Mia wants to borrow £6000 and repay it, with interest, after two years. she sees two offers for loans: offer 1 compound interest 3% per year offfer 2 compound interest first year 1% second year 3% mia says, iwill payback the same amount because the average of 1% and 5% is 3% is she correct?
Answers
Answer:
she is wrong, offer 2 results in lower interests
Step-by-step explanation:
total amount paid if offer 1 is accepted:
$6,000 x (1 + 3%)² = $6,000 x 1.0609 = $6,365.40
she will pay $365.40 in interests
total amount paid if offer 2 is accepted:
($6,000 x 1.01) x 1.05 = $6,060 x 1.05 = $6,363
she will pay $363 in interests
Compounding interest refers to interest that earns more interest itself, e.g. in the first offer, the $180 of interests charged for the first year will earn $5.40 in extra interests. While offer 2 only charges $60 in interests during the first year which will in turn earn $3 of interests. The difference between both offers is that interest charges in offer 1 earn more interests than the interest in offer 2 = $5.40 - $3 = $2.40

Answer:
see attached
Step-by-step explanation:
The graph of the inverse of a function is its reflection in the line y=x. In the attached, that line is shown as a dashed yellow line. The inverse function is shown as a blue line.
__
One way to plot the inverse function of a line is to swap the x- and y-coordinates of the line's intercepts.
In A, the x-intercept is about 10, and the y-intercept is about -4. For the inverse function, the y-intercept will be 10 and the x-intercept will be -4.
In B, the x- and y-intercepts of the function are -6 and 6, respectively. For the inverse function, they will be 6 and -6, respectively.

Answers
Answer:
y=-1/8x +4
Step-by-step explanation:
1. First, write the equation in point-slope form: y-y1=m(x-x1)
y-1=-1/8(x-24)
2. Distribute -1/8 to x and -24
-1/8 times x = -1/8x
-1/8 times -24 = 3
y-1=-1/8x+3
3. Add 1 to both sides
y=-1/8x +4

Using the pythagorean Theorem formula (a^2 + b^2 + c^2) Plug in A and B (13, and 13).
(13)^2 + (13)^2 = c^2
13 • 13 + 13 • 13 = c^2
169 + 169 = c^2
v/338 = v/c^2 (square root them both)

Write in y=mx+b form
Answers
Answer:
y = -2/3x
Step-by-step explanation:
To write in y=mx+b form, you need the y-intercept (b) and the slope (m).
The y-intercept is the point the line crosses the y-axis. This line crosses the y-axis of (0, 0). This makes the y-intercept equal to 0.
The slope is the rise of the line over the run of the line. Pick two points from the line. It doesn't matter which ones, you will get the right answer regardless.
I picked (0, 0) and (-3, 2). Subtract the x-values from each other, and subtract the y-values from each other.
-3 - 0 = -3 (x)
2 - 0 = 2 (y)
Divide the y by the x to find the slope.
2/-3 = -2/3
Plug in the slope and y-intercept into the equation.
y = mx + b
y = -2/3x + 0
y = -2/3x

Answers
Answer:
[tex]Rate = \$0.175/0z[/tex] --- Regular
[tex]Rate = \$0.1705/0z[/tex] --- Large
Step-by-step explanation:
Required (Missing from the question)
Determine the price per ounce
From the question, we have the following given parameters:
For the regular size:
Size = 10oz
Price = $1.75
For the large size:
Size = 22oz
Price = $3.75
The price per ounce is calculated using
[tex]Rate = \frac{Price}{Size}[/tex]
For the regular size:
[tex]Rate = \frac{\$1.75}{10oz}[/tex]
[tex]Rate = \$0.175/0z[/tex]
For the large size:
[tex]Rate = \frac{\$3.75}{22oz}[/tex]
[tex]Rate = \$0.1705/0z[/tex]
