Answer:

$Model = 80cm$

Step-by-step explanation:

Given

$Length = 19.2\ m$

$Scale=1:24$

Required

Determine the scale measurement in centimeters

The scale can be represented as: $Model : Actual$

$Scale = Model : Actual$

Substitute 19.2 for Actual Length

$Scale = Model : 19.2\ m$

Represent as a fraction

$Scale = \frac{Model}{19.2m}$ --- (1)

Recall that:

$Scale=1:24$

Represent as a fraction

$Scale = \frac{1}{24}$ --- (2)

Equate (1) & (2)

$\frac{Model}{19.2m} = \frac{1}{24}$

Multiply through by 19.2m

$Model = \frac{1}{24} * 19.2m$

$Model = \frac{ 19.2m}{24}$

Convert to centimeter

$Model = \frac{ 19.2 * 100cm}{24}$

$Model = \frac{ 1920cm}{24}$

$Model = 80cm$

<em>Hence, the length of the scale model is 80 cm</em>

Help please ;-; The values in the table represent a linear function.

Fittoniya [83]

Answer:

The function rule in slope-intercept form is:

$y = \frac{1}{2}x-\frac{7}{2}$

Step-by-step explanation:

The slope-intercept form of a function is given as:

$y = mx+b$

Here

m is the rate of change of function and b is the y-intercept

The rate of change is calculated as:

$m = \frac{difference\ in\ y}{difference\ in\ x}$

For this, any two pairs of input and output can be taken.

So using the pairs (1,-3) and (2,-1)

$m=\frac{2-1}{-1+3}\\=\frac{1}{2}$

Putting the value of slope in slope-intercept form

$y = \frac{1}{2}x+b$

Putting (1,-3) in the equation

$-3 = \frac{1}{2}(1)+b\\-3 = \frac{1}{2}+b\\b = -3-\frac{1}{2}\\b = \frac{-6-1}{2}\\b= \frac{-7}{2}$

Putting the value of b

$y = \frac{1}{2}x-\frac{7}{2}$

Hence,

The function rule in slope-intercept form is:

$y = \frac{1}{2}x-\frac{7}{2}$

Answer:

x = -8, 8

Step-by-step explanation:

The argument of the absolute value function can be positive or negative to give the same result.

|-8| = 8 ⇒ x = -8

|8| = 8 ⇒ x = 8

The possible solutions are x = -8, 8.
