How is a tangent different from a chord? Explain.
Answers
The main difference between tangent and chord is that the tangent touches the curve at only one point whereas the chord touches the curve at two points.
Chord:
A chord is the line segment joining two points on a curve. The term is often used to describe a line segment whose ends lie on a circle.Tangent:
The tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve.The tangent makes an angle of 90 degree with the radius of circle at the point of contact.From above definitions of Chord and Tangent , we say that chord touches the curve at two points where as Tangent touches the curve at only one point .

A tangent is a line that touches a circle at only one point and is perpendicular to the radius at the point of contact, while a chord is a line segment with both endpoints on the circle.
A tangent and a chord are lines that relate to the curve of a circle, but they have distinct differences. A tangent is a line that touches a circle at exactly one point, and at this point of contact, it is perpendicular to the radius of the circle, which is called the axis in this context. In sharp contrast, a chord is a line segment whose endpoints both lie on the circle. When constructing the perpendicular from the midpoint of a chord, you are drawing an axis. For tangents, the perpendicular erected from the point of contact with the circle is also an axis.
This shows that the tangent is unique in that it has a "no-cut" property; it is the only line that will touch the circle at that single point without cutting through it. When looking at the slope of curves, the slope of the tangent line at the point of contact represents the exact slope of the curve at that point. The differentiation process in mathematics is used to find this slope of the tangent, which is important for understanding the rate of change at a specific point on a curve.

What is the length of the shortest side of a triangle that has vertices at (-2, 5), (-2, -7), and (-6, -4)?
Answers
The shortest side of the triangle with vertices at (-2, 5), (-2, -7), and (-6, -4) is 5 units. The lengths were calculated using the distance formula derived from the Pythagorean theorem.
Explanation:The subject matter of the given question pertains to the discipline of Geometry, specifically, the calculation of the length of the sides of a triangle. To find the length of the shortest side of a triangle having vertices at (-2, 5), (-2, -7), and (-6, -4), we can use the distance formula, which is derived from Pythagoras' theorem.
The formula for calculating the distance between two points (x₁, y₁) and (x₂, y₂) in a coordinate plane is:
√((x₂ - x₁)² + (y₂ - y₁)²)
The distance between the points (-2,5) and (-2,-7) is: √((-2 - (-2))² + (-7 - 5)²) = √(0 + 144) = √144 = 12 unitsThe distance between the points (-2,5) and (-6,-4) is: √((-6 - (-2))² + (-4 - 5)²) = √(16 + 81) = √97 units [approx. 9.85 units]The distance between the points (-2,-7) and (-6,-4) is: √((-6 - (-2))² + (-4 - (-7))²) = √((16 + 9) = √25 = 5 unitsThus, the shortest side of the triangle is the one with length 5 units.

#SPJ12
The length of the shortest side of the triangle is 5.
To find the shortest side of the triangle with vertices at (-2, 5), (-2, -7), and (-6, -4), use the distance formula [tex]\( \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \)[/tex]:
1. Between (-2, 5) and (-2, -7):
[tex]\[ \sqrt{( -2 - (-2) )^2 + ( -7 - 5 )^2} = \sqrt{0 + 144} = 12 \][/tex]
2. Between (-2, 5) and (-6, -4):
[tex]\[ \sqrt{( -6 - (-2) )^2 + ( -4 - 5 )^2} = \sqrt{16 + 81} = \sqrt{97} \approx 9.85 \][/tex]
3. Between (-2, -7) and (-6, -4):
[tex]\[ \sqrt{( -6 - (-2) )^2 + ( -4 - (-7) )^2} = \sqrt{16 + 9} = 5 \][/tex]
Thus, the shortest side is 5 units.

what is a1 of the arithmetic sequence for which a3=126 and a64=3,725
Answers
d=a64-a3/64-3
d=3725-126/61=59
a3=a1+2d
126=a1+118
a1=8
Answer: The required value of the first term is 8.
Step-by-step explanation: We are given to find the first term of the arithmetic sequence for which the third term is 126 and sixty fourth term is 3725.
We know that
the nth term of an arithmetic sequence with first term a and common difference d is given by
[tex]a_n=a+(n-1)d.[/tex]
According to the given information, we have
[tex]a_{3}=126\\\\\Rightarrow a+(3-1)d=126\\\\\Rightarrow a+2d=126~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
and
[tex]a_{64}=3725\\\\\Rightarrow a+(64-1)d=3725\\\\\Rightarrow a+63d=3725~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]
Subtracting equation (i) from equation (ii), we get
[tex](a+63d)-(a+2d)=3725-126\\\\\Rightarrow 61d=3599\\\\\Rightarrow d=59.[/tex]
From equation (i), we get
[tex]a+2\times59=126\\\\\Rightarrow a=126-118\\\\\Rightarrow a=8[/tex]
Thus, the required value of the first term is 8.

<=> b/2 - b = 0
<=> b(1/2 - 1) = 0
<=> b.(-1/2) = 0 ((-1/2) multiplied by sthing equals 0, if we multiply two numbers and the result is 0 then at least one of the two is equal to 0, since (-1/2) isn't equal to 0 then b=0)

The median salary for the Dallas Cowboys was $441,300 in 2000 and $1,326,720 in 2008. Write a linear equation giving the median salary y in terms of the year x. Then use the equation and predict the median salary in 2016.
Answers
The linear equation that is asked from the problem takes the form of:
y = m x + b
where,
y = the median salary
x = the number of years
m = the slope of equation
b = y-intercept
The slope of the equation (m) can be calculated using the formula:
m = (y2 – y1) / (x2 – x1)
m = (1326720 – 441300) / (2008 – 2000)
m = 110,677.5
The y-intercept is then obtained by using any of the data pair:
441300 = 110677.5 (2000) + b
b = -220913700
Therefore the complete equation is:
y = 110677.5 x – 220913700
The median salary in 2016 is therefore:
y = 110677.5 (2016) – 220913700
y = $2,212,140
Answer:
$2,212,140
Sam rented a truck for one day. There was a base fee of $19.99, and there was an additional charge of 75 cents for each mile driven. Sam had to pay $159.49 when he returned the truck. For how many miles did he drive the truck?
Answers
Final answer:
Sam drove 186 miles with the truck he rented. To calculate this, the total paid was subtracted by the base fee, and the result was then divided by the per-mile charge.
Explanation:
The student is asked to calculate the number of miles driven by Sam based on the total cost of truck rental and the additional charge per mile. We use a linear equation to represent the total cost (C) as the sum of the base fee (F) and the product of the number of miles (m) and the charge per mile (P).
The equation for this problem is:
C = F + (P × m)
We are given:
The total cost of rental (C) = $159.49
The base fee (F) = $19.99
The charge per mile (P) = $0.75/mile
Substituting the values we have into the equation gives us:
$159.49 = $19.99 + ($0.75 × m)
To find the number of miles (m), we need to isolate the variable m. We do this by subtracting the base fee from the total cost:
$159.49 - $19.99 = $0.75 × m
$139.50 = $0.75 × m
Now, divide both sides by the charge per mile to get:
m = $139.50 / $0.75
m = 186 miles
Therefore, Sam drove 186 miles.
The demand for a new electric guitar causes a music store to increase the price of the guitar by 45%. If the guitar originally costs $320, what is the new price of the guitar?
Answers
The new price of the guitar is $464.
Hope this helps!
Answer:
The new price of the guitar would be $464.00
Step-by-step explanation:
The original price of the guitar = $320
The music store increased the price of guitar by = 45%
First we calculate 45% of the 320 and then add it to the original price.
The new price of the guitar = 320 + ( 45% × 320 )
= 320 + ( 0.45 × 320 )
= 320 + 144
= $464
The new price of the guitar would be $464.00

2) Again, I'm not 100% sure, but I would say 1.05x10^28 because it's the only one with three digits while the other numbers have two digits
3 & 5) The way scientific notation works is that when you have a positive exponent (like 12 and 16) you move the decimal point to the right that amount of times. So for example, take 5.6E12 (E12 is the same thing as saying 5.6x10^12 btw) the exponent would be 12, so you move the decimal point over 12 times. If you want to double check that you have enough zeros, move the decimal point again, and if it ends up at the end of the number when you hit 12, then you're fine. If you hit 12 in the middle of the number, erase all zeros to the right of the decimal point, and if you hit the end too early, add more zeros until you get it right.
4) Now when you have a negative exponent (-10) you do the opposite of 3 & 5 and move the decimal point to the left that amount of times. In this case, you would move the decimal point 10 times to the left, and you can use the same trick as before to make sure you have enough zeros. I also don't know how nitpicky your teacher is, but I would make sure to add one more zero to the left of the decimal just to make sure (by this I mean getting a number like 0.0005 instead of .0005) because some teachers do want you to do that. I hope this explanation helped :)
