Answer:
#1Segment addition:
RS + ST = RTRS + 17 = 47RS = 47 - 17RS = 30 units#2There are two possibilities:
G is to the left of E. Then G = 3 - 6 = -3G is to the right of E. Then G = 3 + 6 = 9So possible coordinates of G are -3 or 9
#3The length of the segment is the absolute value of the difference of the end point coordinates.
AB = 4 - (-2) = 4 + 2 = 6 unitsStep-by-step explanation:

Explain how you get this answer
9514 1404 393
Answer:
= 0.108
Step-by-step explanation:
Use a calculator or long division.
When using long division, it is convenient to move the decimal points in both numbers to the right 2 places. This makes the divisor an integer, so makes it easier to keep track of appropriate place value in the quotient.
0.189/1.75 = 18.9/175 = 0.108

What is -1 7/8 + -2 1/4? Please explain why and a step by step :).
9514 1404 393
Answer:
-4 1/8
Step-by-step explanation:
Many people find it easier to factor out -1, then do the addition. The fractions need a common denominator before they can be added. A suitable denominator that is a multiple of both 4 and 8 is 8.
The fraction 1/4 = (1/4)(2/2) = (1·2)/(4·2) = 2/8.
__
So, the problem can be rewritten as ...
-(1 7/8 +2 2/8)
= -((1+2) +(7/8 +2/8))
= -(3 +9/8)
The fraction 9/8 is an improper fraction equal to 8/8 +1/8 = 1 1/8. Then the sum is ...
-(3 +1 1/8) = -4 1/8

Solve the equation z^4+4z^2+16=0
Answer:
As this is a quartic equation, we should expect four roots (although some may end being repeated). Notice also that the equation is symmetrical, which suggests that there might be an element of symmetry in the answer.
First, as this equation is a quadratic in terms of z2 , we can use our formula for finding the roots of a quadratic equation to give the value(s) of z2 . [If you have a problem seeing this, use the substitution y=z2 , and you get a quadratic in y .]
z2=−4±42−4×1×16√2×1=−4±16−64√2
=−4±−48√2=−2±12−−√i=−2±23–√i
=4(−12±3√2)i
=4(cos(2kπ3)+isin(2kπ3)) , where k∈1,2
=4e2kiπ3
As this is the value of z2 , whereas we want z , we need to take the square roots of both sides
z=4–√ekiπ3+nπ , where n∈0,1
=2e(k+3n)iπ3
=2cis((k+3n)iπ3)
As we have two values of k and two values of n , this gives us four solutions.
Writing these angles in terms of degrees, we have: 60, 120, 240 and 300
Evaluating, we end up with the four solutions
z=1±3–√i∪z=−1±3–√i
You can substitute z^2 = x,
Then you get x^2+4x+16=0
Step-by-step explanation:
z=1±3–√i∪z=−1±3–√i
You can substitute z^2 = x,
Then you get x^2+4x+16=0
Then you can use classical x1,2 = (-b +- √[b^2–4ac])/2a
X1,2=(-4+-√[16–16*4])/2
After you solve that you substitute back z^2 = x
determine the value of n and what property is represented.

Find the inverse of the function: f(x)=3x−6

C f−1(x)=−1/3x+12
Answer:
B. [tex] {f}^{ - 1} (x) = \frac{1}{3} x + 2[/tex]
Step-by-step explanation:
[tex]f(x) = 3x - 6[/tex]
[tex]y = 3x - 6[/tex]
[tex]x = 3y - 6[/tex]
[tex]3y - 6 = x[/tex]

7. Given directed line segment RT below, find the coordinates of S such that the ratio of RS to ST is 5:1. Plot point S
A line can be divided in proportions using ratios. The point at which a line is divided in ratios is calculated using: [tex][\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]
The coordinate of S is: [tex](6,\frac{8}{3})[/tex]Given that:
[tex]RS : ST = 5 : 1[/tex]
The coordinates of RT are not given. So, I will solve using a general explanation.
When a line is divided into ratios, the point (S) at which the line is divided is calculated using the following line ratio formula:
[tex]S = [\frac{mx_2+ nx_1}{m+n},\frac{my_2+ ny_1}{m+n}][/tex]
Assume the coordinate of R and T is:
[tex]R = (1,6)\\T = (7,2)[/tex]
[tex]RS : ST = 5 : 1[/tex] means:
[tex]m:n = 5:1[/tex]
So, point S is:
[tex]S = [\frac{5\times 7+ 1 \times 1}{5+1},\frac{5 \times 2+ 1 \times 6}{5+1}][/tex]
[tex]S = [\frac{36}{6},\frac{16}{6}][/tex]
[tex]S = [6,\frac{8}{3}][/tex]
Hence, if the coordinates of R and T are:
[tex]R = (1,6)\\T = (7,2)[/tex]
And the line ratio is:
[tex]m:n = 5:1[/tex]
The coordinate of S is:
[tex]S = [6,\frac{8}{3}][/tex]

9. Use Structure Point K is of the way from |(4,-5) to L(0, -7). a. What are the coordinates of Kif n = 4? b. What is a formula for the coordinates of K for any n?
Dividing the segments, it is found that:
a) The coordinates of K if n = 4 are [tex](5,-frac{9}{2})[/tex]b) [tex]K - J = \frac{1}{n}(J - L)[/tex]----------------------------
The endpoints are [tex]J(4,-5)[/tex] and [tex]L(0,-7)[/tex].Point K is (x,y).Since point K is [tex]\mathbf{\frac{1}{n}}[/tex] of the way from J to L, it means that:[tex]K - J = \frac{1}{n}(J - L)[/tex]
And this is the answer to option b.
----------------------------
Option a:
If [tex]\mathbf{n = 4}[/tex], it has that:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
This is applied to find both the x-coordinate and the y-coordinate of K.
----------------------------
The x-coordinate of K is x.The x-coordinate of J is 4.The x-coordinate of L is 0.Thus:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
[tex]x - 4 = \frac{1}{4}(4 - 0)[/tex]
[tex]x - 4 = 1[/tex]
[tex]x = 5[/tex]
----------------------------
The y-coordinate of K is y.The y-coordinate of J is -5.The y-coordinate of L is -7.Thus:
[tex]K - J = \frac{1}{4}(J - L)[/tex]
[tex]y - (-5) = \frac{1}{4}(-5 - (-7))[/tex]
[tex]y + 5 = \frac{2}{4}[/tex]
[tex]y = \frac{1}{2} - 5[/tex]
[tex]y = \frac{1}{2} - \frac{10}[2}[/tex]
[tex]y = -\frac{9}{2}[/tex]
The coordinates of K if n = 4 are [tex](5,-frac{9}{2})[/tex]

The perimeter of a rectangle is 82 meters. If the length of the rectangle is 20 meters more than the width
of the rectangle, find its length and width.
Answer:
30.5 meters
10.5 meters
Step-by-step explanation:
x = length
y = width
x = y + 20
2x + 2y = 82 (the perimeter of a rectangle)
using the first equation as substitute in the second equation we get
2×(y + 20) + 2y = 82
2y + 40 + 2y = 82
4y = 42
y = 42/4 = 21/2 = 10.5 meters
x = y + 20 = 21/2 + 20 = 21/2 + 40/2 = 61/2 = 30.5 meters
