keeping in mind that the points are A(-8 , 6) and C(2 , 5), so

$\textit{internal division of a segment using a fraction}\\\\ A(\stackrel{x_1}{-8}~,~\stackrel{y_1}{6})\qquad C(\stackrel{x_2}{2}~,~\stackrel{y_2}{5})~\hspace{8em} \frac{2}{5}\textit{ of the way from A to C} \\\\[-0.35em] ~\dotfill\\\\ (\stackrel{x_2}{2}-\stackrel{x_1}{(-8)}~~,~~ \stackrel{y_2}{5}-\stackrel{y_1}{6})\qquad \implies \qquad \stackrel{\stackrel{\textit{component form of}}{\textit{segment AC}}}{\left( 10 ~~,~~ -1 \right)} \\\\[-0.35em] ~\dotfill$

This question is incomplete because it lacks the appropriate diagram.

Please find attached to this answer , the appropriate diagram

Answer:

First option tan x° = 8 ÷6

Step-by-step explanation:

When we solve for angles in a right angled triangle or we are trying to find one if the sides of a right angled triangle, we used trigonometric functions to find our answers. These trigonometric functions include Sine (sin) , Cosine (cos) and Tangent (tan)

Tangent also called short form tan is used when solving problems involving a right angled triangle.

A right angled triangle has 3 sides, the Hypotenuse, the opposite side and the adjacent side.

When we are asked to find the tangent of an angle,

tan = Opposite side / Adjacent side

In the question above, we are asked to find tan x° where x is the angle.

The opposite side = 8cm

The adjacent side = 6cm

Therefore, tan x° = 8cm/6cm = 8cm ÷ 6cm

3/7 of the people living in the apartment building are men. 5/8 of the remaining are women. The rest are children. A total of 27

Vladimir [108]

People in building ---- x (men, women and children)
children --- y
men + women + children = x
(3/7)x + (5/8)(4/7)x + y = x
3x/7 + 5x/14 + y = x
times 14
6x + 5x + 14y = 14x
14y = 3x

y + 220 =x
sub into the other one
14y = 3(y+220)
11y = 660
y = 60
then 14(60) = 3x ---> x = 280

So we have 280 people in the building.

check: 3/7 of 280 are men = 120
leaving 160 women and children
5/8 of these ot 100 are women

so we have 120 men, 100 women and 60 children!

hope this is right! have a great. day

Assume that the salaries of elementary school teachers in the United States are normally distributed with a mean of $37,000 and

UkoKoshka [18]

Answer:

New cut off salary = 30,592

Step-by-step explanation:

Given:

Normal distributed mean = $37,000

Standard deviation = $5000

Cut off salary = 10%

Find:

New cut off salary

Computation:

Z - left tale value of 10% is -1.2816

Corresponding x-value using x = zs + u

New cut off salary = (-1.2816)(5,000) + 37,000

New cut off salary = -6,408 + 37,000

New cut off salary = 30,592
