Given the graph, find the initial value of the domain [ ___, 2].

The coordinates of point C that forms the triangle is; (2, -1)

We are told that point D divides line segment AB in the ratio of 5:3.

The line segment division formula is;

(x, y) = (m₁x₂ + m₂x₁)/(m₁ + m₂), (m₁y₂ + m₂y₁)/(m₁ + m₂)

For this question;

x₁ = 2; y₁ = -6; x₂ = 10; y₂ = 2; m₁ = 5; m₂ = 3

Thus, (x, y) gives us;

(5*10 + 3*2)/(5 + 3), (5*2 + 3*-6)/(5 + 3)

D(x, y) = (7, -1)

Now, we need to find the coordinates of C

We will use coordinate system which means the coordinate of x will be the as x coordinate of A since, AC is vertical line

And coordinate of y will be same as y in D since CD is horizontal line. Thus, coordinate of C is; C(2,-1).

Do everything in the lines before anything else. -2 becomes a 2 and then you add that with the 12 and divide 12 on both sides to get one.

Answer:

  x = 0 or 4

Step-by-step explanation:

The absolute value function can be resolved into two equations. These one- or two-step equations can be solved in the usual way.

__

  -(x -2) +10 = 12

  -x = 0 . . . . . . . . . simplify, subtract 12

  x = 0 . . . . . . . . . multiply by -1. Check: 0 -2 is negative.

  x -2 +10 = 12

  x = 4 . . . . . . . . . simplify, subtract 8. Check: 4 -2 is positive.

The two solutions are x=0 and x=4.

1)  The volume of the quarter sphere shaped tank is; V =  20510 ft³

2) The volume of the smaller mock-up tank is; 230790 ft³

1)  The volume of the quarter sphere shaped tank is;

V = ⁴/₃πr²

V = ⁴/₃π * 70 * 70

V =  20510 ft³

2) We multiply dimensions by 2 not radius to make 1 whole cylinder. Thus

r = 35 feet remains the same as radius can only be half of a joined circle,

Since vertically cut, we have;

h = 125 * 2 = 250ft

Let's find the Area;

A = πr²

A = π * 35 *  35

A = Surface Area = 3846.5 ft²

Volume = Surface area * h

V = 3846.5 * 120 = 461580 combined.

For each; V = 461580/2 = 230790 ft³

3) Volume of smaller mock-up tank is;

V = (1/6) * 20510

V = 3418.33 ft³

4) 5/6 * 20510 = 17091.66 ft³

For the larger tank the increase is 17092 ft rounded up (0.165 value) of that of the smaller mock up tank. Therefore percentage is 1/6 = 16.67% and 5/6 = 83.33%

Answer:

s = height above ground

s = 60 + 20 t - 4.9 t^2 (standard physics equation on earth)

at t = 0

s = 60 (clearly :)

now when does it hit the bleak earth?

That is when s = 0

4.9 t^2 - 20 t -60 = 0

solve quadratic and use the positive t (the negative t was back before you threw it if you had thrown it from the ground)

t = 6.09 or - 2.01

use t = 6.09

now to do the last part there are two obvious ways to get t at the peak

1. look for vertex of parabola

2. look for halfway between t = -2.01 and t = 6.09

I will do it the hard (11) waay by completing the square

4.9 t^2 - 20 t = -(s-60)

t^2 - 4.08 t = -.204 s + 12.2

t^2 - 4.08 t +2.04^2 = -.204 s +12.2 + 4.16

(t-2.04)^2 = -.204(s-80.2)

so

Answer:

  8 hours 32 minutes

Step-by-step explanation:

Working together, the construction rates add. We can use the given relation to write an equation for the total time when the pair work together.

__

Let k represent Kirk's time (in hours) to build the wall by himself. Then (k-1) is the time it takes for Jeff to build it. Their working-together rate in "walls per hour" is ...

  1/k +1/(k -1) = 1/4

__

Multiplying by 4k(k-1), we have ...

  4(k-1) +4k = k(k -1)

  k² -9k = -4 . . . . . . . . subtract 8k and simplify

  k² -9k +20.25 = 16.25 . . . . . add (9/2)² to complete the square

  k -4.5 = √16.25 . . . . . . . . . take the square root

  k = 4.5 +√16.25 ≈ 8.531129 . . . hours

The fractional hour is ...

  0.531129 × 60 min ≈ 31.9 min ≈ 32 min

It would take Kirk about 8 hours 32 minutes to build the wall by himself.

For most "working together" problems the rates of completing work need to be expressed in jobs per unit time. Usually, the rates are given in terms of time per job, as they are here. That is why reciprocals get involved.

It will take Kirk about 8 hours 32 minutes to build the wall by himself.

Answer:

30%

Step-by-step explanation:

First we find out the difference between them:

$654,030 - $457,821 = $196,209

Then we compare it with the original price:

196,209/654,030 = 0.3

Since 0.3 is 30%, that is 30% decrease in value.

The number of employees taking the bus to an office is reduced by 1.1% from the last year. The relative change will be 1.1%.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that:-

28.6% of city employees ride the bus to work. Last year,29.7% of city employees rode the bus to work.

The relative change will be calculated as follows:-

Relative change =  Present year data - Last year's data

Relative change = 28.6 - 29.7

Relative change  = -1.1%

Therefore the number of employees taking the bus to an office is reduced by 1.1% from the last year. The relative change will be 1.1%.

Answer:

angle 2 = 7x + 1 ( vertically opposite angles)

7x + 1 + 18x + 4 = 180° ( forming linear pair).

7x + 18x + 4 +1 = 180°

25x + 5 = 180°

25x = 180 - 5

25x = 175

x = 7°

angle 2 = 7(7)+ 1

= 50°

The measure of angle ∠2 of the parallel lines is ∠2 = 50°

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line. The intersecting line is known as transversal line.

We can conclude three factors determining parallel lines ,

Alternate angles are equal

Corresponding angles are equal

Co-interior angles add up to 180°

Given data ,

Let the parallel lines be b and c

Now , the measure of ∠1 + ∠2 = 180° ( angles on the same line )

And , the measure of ∠2 = ( 7x + 1 )° ( alternate angles are equal )

So , ( 7x + 1 ) + ( 18x + 4 ) = 180° ( angles on the same line )

On simplifying , we get

25x + 5 = 180

25x = 175

x = 7

So , the measure of angle ∠2 = ( 7 ( 7 ) + 1 )

The measure of angle ∠2 = 50°

Hence , the angle is ∠2 = 50°

Trigonometry is defined as the branch of mathematics dealing with the relations of the sides and angles of triangles and with the relevant functions of any angles. There are three basic trigonometric ratios: sine, cosine, and tangent. Trigonometry and its functions have an enormous number of uses in our daily life. For instance, it is used in geography to measure the distance between landmarks, in astronomy to measure the distance of nearby stars and also in the satellite navigation system.

The trigonometric function of sine for an acute angle is the ratio between the leg opposite the angle when it is considered part of a right triangle and the hypotenuse while the cosine is the ratio of the base and the hypotenuse.
