Determine the finance charge on a $7,200 car loan if monthly payments were $158.50 for 48 months.
$7,608
$408
$150
$3
PLAESE HURRY
Using proportions, it is found that the finance charge was of $408.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, monthly payments of $158.50 were made for 48 months, hence the total amount paid was of:
48 x $158.5 = $7,608.
The finance charge is the price financed subtracted by the fixed price, hence:
$7,608 - $7,200 = $408.
The finance charge was of $408.

Answer(s):
[tex]\displaystyle y = 3cos\:(2\pi{x} - \frac{\pi}{2}) + 3 \\ y = -3sin\:(2\pi{x} \pm \pi) + 3 \\ y = 3sin\:2\pi{x} + 3[/tex]
Step-by-step explanation:
[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 3 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{\frac{1}{4}} \hookrightarrow \frac{\frac{\pi}{2}}{2\pi} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{1} \hookrightarrow \frac{2}{2\pi}\pi \\ Amplitude \hookrightarrow 3[/tex]
OR
[tex]\displaystyle y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 3 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{1} \hookrightarrow \frac{2}{2\pi}\pi \\ Amplitude \hookrightarrow 3[/tex]
You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the sine graph, if you plan on writing your equation as a function of cosine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = 3cos\:2\pi{x} + 3,[/tex] in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the sine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cosine graph [photograph on the right] is shifted [tex]\displaystyle \frac{1}{4}\:unit[/tex]to the left, which means that in order to match the sine graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle \frac{1}{4}\:unit,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{\frac{1}{4}} = \frac{\frac{\pi}{2}}{2\pi}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = 3cos\:(2\pi{x} - \frac{\pi}{2}) + 3.[/tex]Now, with all that being said, in this case, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph hits [tex]\displaystyle [-\frac{1}{4}, 0],[/tex]from there to [tex]\displaystyle [\frac{3}{4}, 0],[/tex]they are obviously [tex]\displaystyle 1\:unit[/tex]apart, telling you that the period of the graph is [tex]\displaystyle 1.[/tex]Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 3,[/tex]in which each crest is extended three units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.

Pentagon with square measuring 7 inches by 4 inches and two triangles with heights of 6 inches and 5 inches.
A 50 in2
B 59 in2
C 85 in2
D 90 in2
Answer:
B) 59 in²
Step-by-step explanation:
From inspection of the diagram, we can see that the polygon is made up of one rectangle and two triangles.
Area of a rectangle = width × length
Given:
width = 4 inlength = 7 in⇒ area = 4 × 7 = 28 in²
Area of a triangle = 1/2 × base × height
Given:
base = 7 inheight = 6 in⇒ area = 1/2 × 7 × 6 = 21 in²
Area of a triangle = 1/2 × base × height
Given:
base = 4 inheight = 5 in⇒ area = 1/2 × 4 × 5 = 10 in²
Total area = 28 + 21 + 10 = 59 in²

Answer:1.625=158
Step-by-step explanation:
Answer:
1.625=158
Showing the work
Rewrite the decimal number as a fraction with 1 in the denominator
1.625=1.6251
Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000
1.6251×10001000=16251000
Find the Greatest Common Factor (GCF) of 1625 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 125,
1625÷1251000÷125=138
Simplify the improper fraction,
=158
In conclusion,
1.625=158

Answer:
Have to pay $15.12 but with the 15% tip, it's $16.56.
Step-by-step explanation:
To find how the amount to pay, you do y=a(b)^x.
In this case, it would be y=14.40(1.05)^1. You get the 1.05 from adding the 5% to 100 then turning it into a decimal (dividing by 100).

triangle abc has angle measures as shown (look at image).
(a) using the triangle sum theorem, write the equation and solve for x.
(b) what is the value of < b? show your work.
Answer:
a) x = 6° b) m∠B = 50°
Explanation:
(a) total angle measure of a triangle is 180°
8x + 2 + 70° + 60° = 180°
8x + 132° = 180°
8x = 180° - 132°
8x = 48°
x = 6°
(b)
m∠B = 8x + 2
m∠B = 8(6) + 2°
m∠B = 48° + 2°
m∠B = 50°
Answer:
A. X is 6 and B. Angle is 50
Step-by-step explanation:
PART A
Triangle sum theorem explains that all angles in a triangle add up to 180
(8x + 2) + 70 + 60 = 180
8x= 180-70-60-2
8x= 48
X= 48/8 =6
PART B
Using the formula provided, replace the x with 6

Mario and Patience are making cookies. They are ready to drop balls of dough on baking sheets. They have baking sheets made of treated glass, aluminum, stainless steel, and copper. The specific heats of these substances are: Treated glass = 0. 75 J/g • °C Aluminum = 0. 90 J/g • °C Stainless steel = 0. 50 J/g • °C Copper = 0. 39 J/g • °C Based on the specific heat values, which sheet is going to warm up the quickest, and, therefore, bake the cookies the fastest?.
The sheet used by Mario and Patience which is going to warm up the quickest, and, therefore, bake the cookies the fastest is copper sheet.
What is specific heat?The specific heat of a substance is the amount of heat needed, to raise the temperature of the of one gram of substance by unit degree Celsius.
The specific heat capacity of the substance can be given as,
[tex]C=\dfrac{Q}{m\Delta T}[/tex]
Here, (m) is the mass of the substance, (Q) is heat energy and
is the change in temperature.
The above formula can be rewritten as,
[tex]{Q}={m\Delta T}C[/tex]
By this formula, we can say that the heat energy is directly proportional to the specific heat of the substance.
Thus the value of heat energy required to warm up the substance will be higher with the higher value of specific heat and result of it the substance require more time to warm up.
Here, the specific heats of these substances are:
Treated glass = 0. 75 J/g • °C
Aluminum = 0. 90 J/g • °C
Stainless steel = 0. 50 J/g • °C
Copper = 0. 39 J/g • °C
In the above data, the value of specific heat of copper is less than other three substances.
Hence, the sheet used by Mario and Patience which is going to warm up the quickest, and, therefore, bake the cookies the fastest is copper sheet.

Since the opposite side of the quadarilateral are equal hence it is a rectangle.
Perimeter of a rectangleThe sum of the external side is equal to the perimeter. The perimeter of the shape is expressed as:
P = 2(l+w)
where:
P = 120cm
If the width is 30cm less than twice it’s length, then;
w = 2l + 30
Substitute
120 = 2(l + 2l + 30)
60 = 3l + 30
3l = 30
l = 10
