High interest rates make it difficult for people to pay off credit card debt in a reasonable period of time. The interest I (in dollars) paid on a $10,000 debt over 3 years when the interest rate is r% can be approximated by the equation shown below.†
I
175.393
+ 0.663 = r
If the credit card interest rate is 23.6%, find the amount of interest paid during the 3 years.
Answer:
Step-by-step explanation:
We are told that the equation is for a 3 year debt, which is also the period over which the . This means that we can use the equation.
(I/175.393) + 0.663 = r
We are given r = 23.6%
Plugging this vakue in for r gives;
l/175.393 + 0.663 = 23.6
l/175.393 = 23.6 - 0.663
l/175.393 = 22.937
I = 175.393 x 22.937
I = $4022.99, which is approximately
$ 4023
please give an answer Rationalise the denominator and find the values of a and b. 7−4√3/7+4√3 = a + b √3
Answer:
a = 97, b = - 56
Step-by-step explanation:
Given
[tex]\frac{7-4\sqrt{3} }{7+4\sqrt{3} }[/tex]
To rationalise multiply numerator/ denominator by the conjugate of the denominator.
The conjugate of 7 + 4[tex]\sqrt{3}[/tex] is 7 - 4[tex]\sqrt{3}[/tex]
= [tex]\frac{(7-4\sqrt{3})(7-4\sqrt{3}) }{(7+4\sqrt{3})(7-4\sqrt{3}) }[/tex] ← expand numerator/ denominator using FOIL
= [tex]\frac{49-28\sqrt{3}-28\sqrt{3}-48 }{49-48}[/tex]
= [tex]\frac{97-56\sqrt{3} }{1}[/tex]
= 97 - 56[tex]\sqrt{3}[/tex]

rewrite in a slope-intercept form and graph
Answer:
[tex]y=\frac{3}{2}x+3[/tex]
Step-by-step explanation:
Take the given equation:
[tex]-3x+2y=6[/tex]
Solve for y so that the equation is written in slope-intercept form:
[tex]y=mx+b[/tex]
m is the slope and b is the y-intercept. x and y are the coordinate points (x,y).
Solve for y:
Add 3x to both sides of the equation:
[tex]-3x+3x+2y=6+3x\\\\2y=3x+6[/tex]
Divide both sides of the equation by 2 to isolate y:
[tex]\frac{2y}{2}=\frac{3x+6}{2} \\\\ y=\frac{3}{2}x+3[/tex]
The slope is [tex]\frac{3}{2}[/tex] and the y-intercept is 3.
To graph, you need two points. You can use the y-intercept as one.
The y-intercept is the place where the line crosses over the y-axis, where x equals 0, so the point is (0,3).
Next, take any value for x and insert it into the equation. We'll use 2:
[tex]y=\frac{3}{2}(2)+3[/tex]
Using this, you can solve for the value of y when x is equal to 2.
Simplify:
[tex]\frac{3}{2} *\frac{2}{1}=\frac{6}{2}=3 \\\\y=3+3\\\\y=6[/tex]
So, when x=2, y is 6 (2,6).
Plot the points (0,3) and (2,6)
Draw a straight line through the two, going past both.
:Done
In the graph, one square is 1 unit

Write this equation in slope-intercept form (y = mx + b).
y-2=-3(x - 4)
Answer:
[tex]\huge\boxed{y=-3x+14}[/tex]
Step-by-step explanation:
[tex]y-2=-3(x-4)\\\\y-2=-3x+12\\\\y-2+2=-3x+12+2\\\\\boxed{y=-3x+14}[/tex]
First distribute the -3 through the parenthses
which gives us y - 2 = -3x + 12.
Move the number to the right side of the equation
by adding 2 to both sides to get y = -3x + 14.
Notice that the equation above is written in slope-intercept form because
the y term is isolated or by itself on the left side of the equation.

a 1
b 4
c 5
d 25
Answer:
a) 1
Step-by-step explanation:
3(x + 1) = -2(x - 1) +6
3x + 3 = -2x + 2 + 6
3x + 3 = -2x + 8
Subtract 3 from both sides
3x + 3 -3 = -2x + 8 -3
3x = - 2x + 5
Add 2x to both sides
3x + 2x = -2x + 5 +2x
5x = 5
Divide both sides by 5
5x/5 = 5/5
x = 1

Which statement describes how the graph of a function, h(x), and its inverse, h‒1(x), are related? The line y = ‒x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h‒1(x). The line y = x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h‒1(x). The graph of the inverse of h(x) is a reflection over the line y = 0 of the graph of h(x). The y-axis is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h‒1(x).
Answer:
Option B.
Step-by-step explanation:
We know that, if the graph of a function is reflected across the line y=x, then we get the graph of inverse of that function.
It means, the graph of inverse function is the mirror image of graph of function across the line y=x.
If h(x) is a function and h⁻¹(x) is its inverse function, then the line y = x is the perpendicular bisector of each segment connecting a point on h(x) to the corresponding point on h⁻¹(x).
Therefore, the correct option is B.

PLEASE HELP!! Which equation can be used to solve 2 6 0 1 * x1 x2 = 2 -3
Answer:
Equation :
[tex]\begin{bmatrix}x_1\\ x_2\end{bmatrix}=\begin{bmatrix}\0.5}&-3\\ 0&1\end{bmatrix}}\begin{bmatrix}2\\ -3\end{bmatrix}[/tex]
Step-by-step explanation:
To isolate the following matrix, we will have to divide either by matrix 1, or the co - efficient of the matrix shown below. By doing so we will have to take the inverse of the co - efficient of that same matrix on the other side. In other words,
[tex]\begin{bmatrix}x_1\\ x_2\end{bmatrix}[/tex] - Matrix which we have to isolate,
[tex]\begin{bmatrix}x_1\\ x_2\end{bmatrix}=\begin{bmatrix}2&6\\ \:0&1\end{bmatrix}^{-1}\begin{bmatrix}2\\ -3\end{bmatrix}[/tex] - Equation used to solve the matrix
Now as you can see this equation is not any of the given options. That is as we have to simplify it a bit further,
[tex]\begin{bmatrix}2&6\\ 0&1\end{bmatrix}^{-1} = \frac{1}{\det \begin{bmatrix}2&6\\ 0&1\end{bmatrix}}\begin{bmatrix}1&-6\\ -0&2\end{bmatrix} = \frac{1}{2}\begin{bmatrix}1&-6\\ -0&2\end{bmatrix} = \begin{bmatrix}\frac{1}{2}&-3\\ 0&1\end{bmatrix}[/tex]
We know that 1 / 2 can be replaced with 0.5, giving us the following equation to solve for x1 and x2,
[tex]\begin{bmatrix}x_1\\ x_2\end{bmatrix}=\begin{bmatrix}\0.5}&-3\\ 0&1\end{bmatrix}}\begin{bmatrix}2\\ -3\end{bmatrix}[/tex]
As you can see our solution is option d.

Two points in a rectangular coordinate system have the coordinates (5.5, 2.9) and (−3.5, 4.8), where the units are centimeters. Determine the distance between these points.
Answer:
The distance between these points is approximately is 9.198 units.
Step-by-step explanation:
Let be (5.5, 2.9) and (-3.5, 4.8) the location of the points in Cartesian plane. The straight line distance between both points ([tex]d[/tex]) is determined by the Pythagorean Theorem, which is described below:
[tex]d = \sqrt{(x_{B}-x_{A})^{2}+(y_{B}-y_{A})^{2}}[/tex]
Where:
[tex]x_{A}[/tex], [tex]x_{B}[/tex] - Horizontal components of each point, dimensionless.
[tex]y_{A}[/tex], [tex]y_{B}[/tex] - Vertical components of each point, dimensionless.
If [tex]A = (5.5, 2.9)[/tex] and [tex]B = (-3.5,4.8)[/tex], the distance between these points is:
[tex]d = \sqrt{(-3.5-5.5)^{2}+(4.8-2.9)^{2}}[/tex]
[tex]d\approx 9.198[/tex]
The distance between these points is approximately is 9.198 units.

What is 5/7 written as a decimal and written as a percent rounded to the nearest tenth?
Answer:
[tex]\frac{5}{7}:\quad 0.71428\\\\= 0.71\\\\\frac{0.71}{1}\times \frac{100}{100}\\ \\= 71/100\\\\= 71\%[/tex]
Step-by-step explanation:
The fraction 5/7 is equal to 0.7 or 70%.
To convert 5/7 to a decimal,
divide the numerator (5) by the denominator (7):
So, 5 ÷ 7 = 0.71428571...
Rounded to the nearest tenth, the decimal equivalent of 5/7 is 0.7.
Now, to convert 0.7 to a percent, we multiply it by 100:
0.7 x 100
= 70%
Therefore, when rounded to the nearest tenth, 5/7 is equal to 0.7 or 70%.

Answer:
Step-by-step explanation:
Using the identity (x + 0.5)^2 = x(x + 1) + 0.25:
4.5^2 = 4 * 5 + 0.25 = 20.25
Also 4.45^2 = 19.8

Write the equation in standard form for the circle that has a diameter with endpoints (22,0) and (2,0)
Answer:
(x - 12)² + y² = 100
Step-by-step explanation:
The standard form of the equation of a circle is;
(x - a)² + (y - b)² = r²
where:
a and b are the coordinates of the centre of the circle
r is the radius
We are given the coordinates of the endpoints of the diameter as; (22,0) and (2,0)
Thus, the centre of the circle would be at the mid point of the endpoints of the diameter.
Coordinates of the centre is;
((22 + 2)/2), (0 +0)/2))
This is;
(12, 0)
So, a = 12 and b = 0
Now,to get the radius r, we will use the formula;
r = √[(x2 - x1)² + (y2 - y1)²]
Where;
(x1, y1) and (x2, y2) are 2 points namely (12,0) and (22, 0)
r = √[(12 - 22)² + (0 - 0)²]
r = √(-10)²
r = √100
r = 10
Thus,equation of the circle is;
(x - 12)² + (y - 0)² = 10²
(x - 12)² + y² = 100

Work out the thickness of 250 sheets of paper.
Answer:
1/2048 or 4.8828125*10^(-4)
Step-by-step explanation:
First, figure out the thickness of 1 sheet of paper in number format:
[(8*10)]^(-3)=(80)^(-3) or (1/(80)^(3))=1/512000
Now, multiply 1/512000 by 250 to find the thickness of 250 sheets of paper:
250(1/512000)=1/2048
In scientific notation, this is written as 4.8828125*10^(-4).
