PLS HELP ME GIVING BRAINLIEST AND POINTS

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]

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]

Answer:

7).

RT = RS + ST

[tex]10 = (2x - 20) + (2x - 18) \\ 10 = (2x + 2x) + ( - 20 - 18) \\ 10 = 4x - 38 \\ 4x = 10 + 38 \\ 4x = 48 \\ { \boxed{x = 12}}[/tex]

Option A. 3.2 x 10²

Step-by-step explanation:

320 written in scientific notation is 3.2 × 102.

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

Answer:

94

Step-by-step explanation:

When a player reaches 101 points, they win. So that means that Mack reached 101 points. Since his opponent was seven points behind, we can subtract 7 from 101 to find Mark's, that is Mack's opponent's, score:

[tex]101-7=94[/tex]

Therefore, we can safely conjecture that Mark scored 94 points.

Answer:

Step-by-step explanation:

Dividing the segments, it is found 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.

----------------------------

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]

----------------------------

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]

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

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

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
