the distance of a vertex to its 2 neighboring circle touching points is the same, because tangents emanating from the same point to the same circle must have the same distance to the touching points.

so, AB splits into a (from A to the circle touching point on AB) and b (from the circle touching point on AB to B).

b = AB - a

BC splits into b (from B to the circle touching point on BC) = AB - a, and c (from the circle touching point on BC to C).

c = BC - (AB - a) = BC - AB + a

CD splits into c (from C to the circle touching point on CD) = BC - AB + a, and d (from the circle touching point on CD to D).

d = CD - (BC - AB + a) = CD - BC + AB - a

DA now splits into d (from D to the circle touching point on DA) and ... a (from the circle touching point on DA to A).

a = DA - (CD - BC + AB - a) = DA - CD + BC - AB + a

0 = DA - CD + BC - AB

DA = CD - BC + AB = 8 - 5 + 4 = 7

Answer:

  DA = 7

Step-by-step explanation:

You have quadrilateral ABCD with an inscribed circle and side lengths AB=4, BC=6, CD=8, and you want to know the length of DA.

The tangents from each vertex of the quadrilateral to the inscribed circle are the same length, so we can work our way around the quadrilateral to find the missing length. The attached figure shows the tangent lengths working counterclockwise from vertex A.

The sum of the tangents from A and D is ...

  x + (7 -x) = 7

The length of DA is 7 units.

Additional comment

The sum of the lengths of opposite sides is the same in any quadrilateral with an inscribed circle. Here, that sum is 4+8 = 12, so the unknown side is 12-5 = 7.

Answer:.83

Step-by-step explanation:

A line that is parallel to another line has the same slope but a different y-intercept. The slope of the line through the points (1,-2) and (-6,3) can be found using the slope-point formula:

slope = (y2 - y1) / (x2 - x1) = (3 - (-2)) / (-6 - 1) = 5/7

So, a line that is parallel to this line would have the same slope of 5/7. To find an equation for a line with this slope that passes through a different point, we can use the point-slope formula:

y - y1 = m * (x - x1)

Where m is the slope and (x1, y1) is a point on the line. We can choose any point to use in this formula, but a common choice is the origin (0,0). So, plugging in the values we have:

y - 0 = 5/7 * (x - 0)

y = 5/7 * x

This is the equation for a line that is parallel to the line through the points (1,-2) and (-6,3) and passes through the origin.

Answer:

-6

Step-by-step explanation:

using the rules of exponents

• [tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]

• [tex]a^{\frac{1}{2} }[/tex] = [tex]\sqrt{a}[/tex]

then

- 18 × [tex]9^{-\frac{1}{2} }[/tex]

=-  18 × [tex]\frac{1}{9^{\frac{1}{2} } }[/tex]

= - 18 × [tex]\frac{1}{\sqrt{9} }[/tex]

= - 18 × [tex]\frac{1}{3}[/tex]

= -6

Answer: The answer should be -6

Step-by-step explanation:

18(9^−1/2)

= −18(9^−1/2)

= (−18)(0.333333)

= −6

So, what you want to do is first solve 9^-1/2, it will come out to be about 0.333333

You are going to put 0.333333 in for 9^-12 and then multiply:

-18(9^-1/2) = (-18)(0.333333)

(-18)(0.333333) = -6

Andy should write $507.18 for the balance on January 30. The solution has been obtained by using arithmetic operations.

What are arithmetic operations?

Four fundamental mathematical operations can be used to express any real number.

1. To determine the total of the numbers, use the addition operator ('+').

2. Use the sign "-" when subtracting to find the differences between the numbers.

3. Multiply when the result is the product of the numbers.

4. Dividing the numbers produces their quotient.

We are given that the amount balance on January 24 is $104.47 and she deposited $407.71 on January 30.

So, the amount Andy should write for the balance on January 30 is

⇒$104.47 + $407.71

⇒$507.18

Hence, Andy should write $507.18 for the balance on January 30.

Answer:

True

Step-by-step explanation:

True. A z-score, also known as a standard score, is a statistical measure that helps to determine how far a particular value is from the mean relative to the data set's standard deviation.

A z-score is a dimensionless quantity that expresses the distance between a particular value and the mean of a distribution in terms of the number of standard deviations that the value is from the mean. A positive z-score indicates that the value is above the mean, while a negative z-score indicates that the value is below the mean.

To calculate the z-score for a given value, the formula is: z = (x - μ) / σ where z is the z-score, x is the value being considered, μ is the mean of the data set, and σ is the standard deviation of the data set.

For example, if the mean of a data set is 50 and the standard deviation is 10, and we are interested in finding the z-score for a value of 65, the calculation would be: z = (65 - 50) / 10 = 1.5. This indicates that the value of 65 is 1.5 standard deviations above the mean of the data set.

Z-scores are useful for comparing values across different data sets or for identifying extreme values in a data set. Values with high positive or negative z-scores are typically considered to be outliers, indicating that they are further from the mean than most other values in the data set.

In summary, the statement "z-score helps to determine how far a particular value is from the mean relative to the data set's standard deviation" is true. Z-scores are a statistical measure that help to express the distance between a particular value and the mean of a distribution in terms of the number of standard deviations that the value is from the mean.

The rational number representation of Micah withdrawing $4.50 from his bank account is -4.5.

A rational number is any fraction with non-zero denominators. A rational number can be written as a fraction with a numerator and denominator that are both integers.

In this case, we can write $-4.50$ as the fraction $\frac{-450}{100}$, where the numerator represents the amount of money withdrawn (in cents) and the denominator represents the unit of currency used (in this case, 100 cents = 1 dollar).

So, the rational number representing the amount of money withdrawn from Micah's bank account is {-450} / {100}$ = -4.5.

∠RVS = 55° (vertically opposite angles are equal)

∠WVS = 125° (vertically opposite angles are equal)

∠RST =  55 + 55 = 110°  (exterior angle of a triangle)

∠RSV = 180-55-55 = 70° (sum of angles in a triangle is 180°)

∠VSU = 110° (vertically opposite angles are equal)

As a result, on a graph of dP/dt vs P, the curve would be concave down for P b/a and concave up for P > b/a. The curve would reach its maximum when P = b/a, with dP/dt equal to zero.

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.

Here,

The equation dP/dt = aP² - bP represents the rate of change of the population P over time t.

When dP/dt is positive, the population is increasing. When dP/dt is negative, the population is decreasing.

To find when dP/dt is positive and negative, we need to find the critical points where dP/dt = 0.

Solving the equation dP/dt = aP² - bP = 0, we get:

aP² - bP = 0

aP(P - b/a) = 0

This equation has two solutions: P = 0 and P = b/a.

For P < b/a, dP/dt is negative (the population is decreasing). For P > b/a, dP/dt is positive (the population is increasing).

So, on a graph of dP/dt against P, the curve would be concave down for P < b/a and concave up for P > b/a. At P = b/a, the curve would have a maximum and dP/dt = 0.
