Scott borrowed $985 for a new TV and game system. He made 6 monthly payments to repay the loan. He paid $155 interest. What is his simple interest rate?
Answers
Based on the amount that Scott borrowed for the new TV and game system, and the interest paid, the simple interest rate is 15.7%
What is the simple interest rate?The simple interest rate can be found by the formula:
= Interest paid by Scott on the loan / Amount Scott borrowed x 100%
Solving for the simple interest rate gives:
= 155 / 985 x 100%
= 0.1573604060913705583756345177665 x 100%
= 0.157 x 100%
= 15.7%

what is the most general antiderivative for the function 8 x to the power of 4 minus 6 over x to the power of 4 minus 3.
Answers
The most general antiderivative of the given function is (8/5)x^5 - (3/2)ln|x^4 - 3| + C.
To find the most general antiderivative of the function f(x) = 8x^4 - 6/(x^4 - 3), we can use the following steps:
Step 1: Rewrite the function f(x) as a sum of simpler functions. Here, we can split the given function into two parts:
f(x) = 8x^4 - 6/(x^4 - 3)
= 8x^4 - 6(x^4 - 3)^(-1)
Step 2: Find the antiderivative of each part separately.
The antiderivative of 8x^4 is (8/5)x^5 + C, where C is a constant of integration.
To find the antiderivative of 6(x^4 - 3)^(-1), we can use the substitution u = x^4 - 3, which gives du/dx = 4x^3 and dx = (1/4x^3)du. Substituting these values, we get:
∫6(x^4 - 3)^(-1)dx = 6 ∫(x^4 - 3)^(-1)dx
= 6 ∫u^(-1) (1/4x^3)du
= (3/2)ln|x^4 - 3| + C
where ln denotes the natural logarithm.
Step 3: Combine the antiderivatives and simplify.
The most general antiderivative of the function f(x) is thus:
∫f(x)dx = ∫[8x^4 - 6/(x^4 - 3)]dx
= (8/5)x^5 - (3/2)ln|x^4 - 3| + C
where C is a constant of integration.
Therefore, the most general antiderivative of the given function is (8/5)x^5 - (3/2)ln|x^4 - 3| + C.

a finite line segment is drawn from ( 0. , 4.) and ( 4. , 0. ) -- what is its parametric line segment equation?
Answers
The parametric equation of the line drawn ( 0. , 4.) and ( 4. , 0. ) is x + y - 4 = 0
A finite line segment is drawn from two points
Let the point be A and B
The co ordinates of the point A is (0, 4) and the co ordinates of the point B is (4, 0)
The equation of the line can be
y - y₁ =( (y₂-y₁)/(x₂ - x₁))(x - x₁)
y - 4 = ((4 - 0)/(0 - 4))(x - 0)
y - 4 = (4/-4)(x - 0)
y - 4 = -1(x - 0)
y - 4 = -x
y + x -4 = 0
Therefore, the parametric equation of the line drawn from ( 0. , 4.) and ( 4. , 0. ) is x + y - 4 = 0

Consider the case in which the proportionality constant C is equal to 1/2. Plot the graph of y=1/2x. How would you graph?
Answers
To graph the equation y = (1/2)x, we can plot points on a coordinate plane and connect them to create a straight line. Here's how to do it:
1. Choose some x-values to evaluate the equation. Let's select a range of x-values, such as -10, -5, 0, 5, and 10.
2. Substitute each x-value into the equation to find the corresponding y-values. For example:
- For x = -10, y = (1/2)(-10) = -5
- For x = -5, y = (1/2)(-5) = -2.5
- For x = 0, y = (1/2)(0) = 0
- For x = 5, y = (1/2)(5) = 2.5
- For x = 10, y = (1/2)(10) = 5
3. Plot the points (x, y) on a graph. In this case, the points would be:
(-10, -5), (-5, -2.5), (0, 0), (5, 2.5), (10, 5)
4. Connect the plotted points with a straight line. The line should pass through all the points.
The resulting graph is a straight line with a slope of 1/2, passing through the origin (0, 0), and extending infinitely in both directions.
Here is a rough sketch of the graph:

How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Answers
Answer:
1200 ounces
Step-by-step explanation:
How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Let us represent
Number of ounce of 10% copper = x
Hence, our Equation =
x × 10% + 600 × 70% = (x + 600) × 30%
0.1x + 420 = (x + 600)0.3
0.1x + 420 = 0.3x + 180
Collect like terms
0.3x - 0.1x = 420 - 180
0.2x = 240
x = 240/0.2
x = 1200 ounces

Find the volume of the solid generated by revolving the region r bounded by y=e^-2x, y=0, x=0, x=ln9
Answers
The volume of the solid generated by revolving the region R bounded by
y = \(e^{-2x}\), y = 0, x = 0, x = ln 9 around x-axis = 0.25 cubic units
Given the region R bounded by y = \(e^{-2x}\), y = 0, x = 0, x = ln 9.
We will find the volume of the solid obtained by revolving this region around the x-axis through disc integration method.
The disc integration method is used to find the volume of a solid obtained by revolving a region around an axis parallel to x-axis.
Then, volume, V = \(\int\limits^0_{ln9} {y^2} \, dx\)
= \(\int\limits^0_{ln9} {(e^{-2x})^2} \, dx\)
= \(\int\limits^0_{ln9} {e^{-4x}} \, dx\)
= \(\frac{e^{-4x}}{-4} |_{x=0\ to \ x=ln9}\)
= \(\frac{e^{-4 ln9}}{-4} +\frac{1}{4}\)
= \(\frac{9^{-4}+1}{4}\) ≈ 0.25 cubic units

2x1 + 1x2 = 30. Setting x1 to zero, what is the value of x2?
Answers
Setting x1 to zero in the equation 2x1 + 1x2 = 30 results in the value of x2 being 30.
The given equation is 2x1 + 1x2 = 30, where x1 and x2 represent variables. To find the value of x2 when x1 is set to zero, we substitute x1 with zero in the equation.
By replacing x1 with zero, we have 2(0) + 1x2 = 30. Simplifying further, we get 0 + 1x2 = 30, which simplifies to x2 = 30.
When x1 is set to zero, the equation reduces to a simple linear equation of the form 1x2 = 30. Therefore, the value of x2 in this scenario is 30.
Setting x1 to zero effectively eliminates the contribution of x1 in the equation, allowing us to focus solely on the value of x2. In this case, when x1 is removed from the equation, x2 becomes the sole variable responsible for fulfilling the equation's requirement of equaling 30. Thus, x2 is determined to be 30.

Answers
Answer:
B. 4 tablespoons
Step-by-step explanation:
Let’s make a proportion using the following setup:
tablespoons/servings=tablespoons/servings
We know that 12 tablespoons are needed for 60 servings.
12/60=tablespoons/servings
We don’t know how many tablespoons are needed for 20 servings. We can say x tablespoons make 20 servings.
12/60=x/20
Want want to solve for x, so we must isolate x. x is being divided by 20. The inverse of division is multiplication. Multiply both sides of the proportion by 20.
20*(12/60)=(x/20)*20
20*12/60=x
20*0.2=x
4=x
x= 4 tablespoons
