Consider each graph shown. Determine the slope of each line
and then use similar triangles to justify that the slope is the
same between any two points.

Answers

Answer:

18,1,18

Step-by-step explanation:

The slope of a line from the given graph is 4 units.

From the given graph, vertical line (rise) = 16 and horizontal line (run) = 4.

What is slope of a line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Now, slope = Rise/Run

⇒ slope = 16/4

= 4 units

Therefore, the slope of a line from the given graph is 4 units.

A triangle has vertices at A(–2, 4), B(–2, 8), and C(6, 4). If A prime has coordinates of (–0.25, 0.5) after the triangle has been dilated with a center of dilation about the origin, which statements are true? Check all that apply.

Answers

Answer:

The scale factor is One-eighth

The coordinates of C prime are (0.75, 0.5).

The coordinates of B prime are (–0.25, 1).

Step-by-step explanation:

A triangle has vertices at A(–2, 4), B(–2, 8), and C(6, 4). If A prime has coordinates of (–0.25, 0.5) after the triangle has been dilated with a center of dilation about the origin, which statements are true? Check all that apply. The coordinates of C prime are (0.75, 0.5). The coordinates of C prime are (1.5, 1). The scale factor is One-eighth. The scale factor is 8. The scale factor is One-fourth. The scale factor is 4. The coordinates of B prime are (–0.25, 1). The coordinates of B prime are (–0.5, 2).

Solution:

Transformation is the movement of a point from its initial location to a new location. If an object is transformed then all its points are also transformed. Types of transformation are reflection, dilation, rotation and translation.

Dilation is the enlargement or reduction in size of an object. If a point X(x, y)  is dilated about the origin by a factor k, its new location is X'(kx, ky)

Triangle ABC with vertices at A(–2, 4), B(–2, 8), and C(6, 4) is dilated to give A'(-0.25, 0.5)

kA = A'

(-2k, 4k) = (-0.25, 0.5)

-2k = -0.25, hence k = 1/8

Therefore the scale factor is 1/8 (one- eight)

The new location of the vertices is B'(-0.25, 1), C'(0.75, 0.5)

An object is dropped off a cliff and falls freely. It speeds up as it falls toward the ground.

The graph below shows the velocity in meters per second (m/s) of the object (denoted by the vertical axis) as a function of time in seconds (denoted by the horizontal axis). Note that the relationship is linear.



This relationship is given by the equation, v = gt. In this equation, g is the acceleration due to gravity, t is the number of seconds, and v is the velocity of the falling object. Note that g is a constant.

Find and interpret the meaning of the initial value and the rate of change in this context.

Answers

Answer:

The initial value is 0. That means that object’s initial velocity 0 m/s. The rate of change is 9.8. That means the acceleration due to gravity is 9.8 m/s 2.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that there are 24 pencils in 8 jars. The number of pencils in each jar will be calculated as,

Number = Number of pencils / Number of the jars

Number = 24 / 8

Number = 3 Pencils

Hence, there will be 3 pencils in each jar.

Carlita saw 5 times as many robins as she did cardinals while bird watching. She saw a total of 36 birds. How many more robins did she see than cardinals?

Answers

Answer: Calita saw 30 Robins and  6 Cardinals

Step-by-step explanation:

Step 1

  writing the mathemathecal expression  becomes

Let robins be represented as R

and Cardinals be represented as C

so our first equation becomes

R+C = 36----- eqn 1

but she saw 5times as many robins as cardinals, with a total of 36 birds making us have

Therefore R= 5C

 5C +C= 36------- eqn 2

STEP  2--- solving equation 2

5C+C = 36

6C= 36

C= 36/6=6

Puting the valueof C=6 in equation 1 becomes

R+C= 36

R+6=36

R=36-6= 30

R=30

Therefore Calita saw 30 Robins and  6 Cardinals

y

Where
m

Substituting the slope we calculated and the y-intercept gives:

The linear equation that is solved by both (-6,2) and (0,-4) is y = -x - 4

Using the slope intercept formula for linear equation,

y = mx + b

where

m = slope

b = y-intercept

Therefore, lets find m

(-6,2) and (0,-4)

m = -4 - 2 / 0 - (-6) = -6 / 6 = - 1

Lets find b using (0,-4)

y = mx + b

-4 = -1(0) + b

b = -4

There the linear equation in slope intercept form will be as follows

y = -x - 4

Answers

Answer:

4.4 hours

Step-by-step explanation:

Let the number of hours be represented as h

The price of Stock A 9 AM was $12.71. Since then, the price has been increasing at the rate of $0.05 each hour

$12.71 + $0.05 × h

12.71 + 0.05h

At noon the price of Stock 8 was \$13.46 . To decrease at the rate of by $0.12each hour.

$13.46 + $0.12 × h

13.46 - 0.12h

If the two rates continue, in how many hours will the prices of the two stocks be the same?

12.71 + 0.05h = 13.46 - 0.12h

0.05h + 0.12h = 13.46 - 12.71

0.17h = 0.75

h = 0.75/0.17

h = 4.41176470588 hours

Approximately = 4.4 hours
