Find the distance between the points ( – 8, – 8) and (6, – 8).
The distance between the points ( – 8, – 8) and (6, – 8) is 14, according to the definition of distance
Distance between two pointsThe distance between two points is equal to the length of the segment that joins them. Therefore, to determine the distance between two different points, you must calculate the squares of the differences between their coordinates and then find the root of the sum of said squares.
That is, given the coordinates of two different points (x₁, y₁) and (x₂,y₂), the expression that allows calculating the distance "d" between two different points on the Cartesian plane is:
d= √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance in this caseIn this case, you know:
(x₁, y₁)= (-8, -8)(x₂,y₂)= (6, -8)Substituting in the definition of distance:
d= √[(6-(-8))² + (-8 - (-8))²]
Solving:
d= √[(6+8)² + (-8 +8)²]
d= √[14² + 0²]
d= √14²
d= √196
d= 14
Finally, the distance is 14.

6. Given WY with W(3, 7) and Y(13, -8), if Xpartitions WY such that the ratio of WX to XYis 3:2, find the coordinates of X.
Answer:
(9, -2)
Explanation:
If a point X partition a segment that starts in point (x1, y1) and ends at point (x2, y2) in a ration a:b, the coordinates of X will be equal to:
[tex](\frac{a}{a+b}(x_2-x_1)+x_1,\frac{a}{a+b}(y_2-y_1)+y_1)[/tex]So, replacing (x1, y1) by point W(3, 7) and (x2, y2) by point Y(13, -8) and the ratio a : b by 3 : 2, we get that the coordinates of X are:
[tex]\begin{gathered} (\frac{3}{3+2}(13-3)+3,\frac{3}{3+2}(-8-7)) \\ (\frac{3}{5}(10)+3,\frac{3}{5}(-15)+7) \\ (6+3,-9+7) \\ (9,-2) \end{gathered}[/tex]Therefore, the coordinates of X are (9, -2)
Write
1/10^-3 using a positive exponent.
1/10⁻³ as a positive exponent is 10³.
How to convert a negative exponent to a positive exponent?
The negative exponent instructs us to rewrite the formula by getting the base's reciprocal and then switching the exponent's sign. A positive exponent indicates that the base should be multiplied by that many. Depending on the question at hand, you must flip an exponent from numerator to denominator or from denominator to numerator in order to change its sign.
Given, the exponent is y = 1/10⁻³
Multiplying both numerator and denominator of y with 10³, we get,
y = 10³/(10⁻³×10³) = 10³/1 = 10³
Therefore, 1/10⁻³ as a positive exponent is 10³.

Find the amount and the present value of an annuity of P540 payable every end ofthe month at 7% compounded monthly for 4 years and 5 months.
We have to find the present value of a annuity of $540 payable every end of the month at 7% compounded monthly for 4 years and 5 months.
We can express the present value PV as:
[tex]PV=M\cdot\frac{[1-(1+r\/m)^{-n\cdot m}]}{r\/m}[/tex]where M: monthly payment (M = 540), r: annual nominal rate (r = 0.07), m: number of subperiods of compounding per year (m = 12) and n: number of years (n = 4+5/12).
We can replace the variables with its value and calculate PV as:
[tex]\begin{gathered} PV=540\cdot\frac{[1-(1+\frac{0.07}{12})^{-53}]}{\frac{0.07}{12}} \\ PV\approx540\cdot\frac{[1-(1.005833)^{-53}]}{0.005833} \\ PV\approx540\cdot\frac{1-0.7347}{0.005833} \\ PV\approx540\cdot\frac{0.2653}{0.005833} \\ PV\approx540\cdot45.4826 \\ PV\approx24560.60 \end{gathered}[/tex]Answer: The present value of teh annuity is P 24560.60.

A data set contains an independent and a dependent variable. Which must be true of the data set if a linear function can be used to represent the data?
The set must have a constant additive rate of change.
The set must have a constant multiplicative rate of change.
The values in the set must be positive.
The values in the set must be increasing.
The correct answer is: The set must have a constant additive rate of change.
Let Y be a data set containing an independent and dependent variable.
The standard form of the equation of a line is given by y = mx + b, where x is an independent variable and y is a dependent variable, m is the slope, and b is the y-intercept.
Now, when m = 1,
y = x + c
When m = 2,
y = 2x + c = x + x + c
When m = 3,
y = 3x + c = x + x + x + c
As a result, the set must change at a constant additive rate.In order to avoid the function changing into an exponential function, which is not linear, the set must not have a constant multiplicative rate of change.As the set of real numbers is the domain of the linear function, the values in the set may be positive or negative.And, the values in the set must be rising.Learn more about data set here:

The measure of angle C is given as follows:

Measure of angle CSegments AD and BE are parallel, hence the angles A and B are congruent, that is, they have the same measure:
<A = <B.
Angle ABE is of 50º, hence the measures of the congruent angles A and B are given as follows:
<A = <B = 50º.
The sum of the measures of the internal angles of a triangle is of 180º, hence the following relation from triangle ABC is established.
<A + <B + <C = 180º.
The measures of angles A and B were already found, hence we can solve for the measure of angle C with the above equation as follows:
<A + <B + <C = 180º.
