Scale drawings are used to draw shapes in a different proportional size

The scale used in the drawing is 17 centimeters : 9 meters

From the question, we have:

So, the scale is:

Scale =  Scale length : Real length

This gives

Scale =  102 centimeters : 54 meters

Reduce the scale

Scale =  17 centimeters : 9 meters

Hence, the scale used in the drawing is 17 centimeters : 9 meters

Answer:

What is the question?

Step-by-step explanation:

Answer:

57 °

Step-by-step explanation:

Complementary angles = 90 °

Since, Your angle don't have ∠ [  ] Then Let let "C" and "y"

Thurs, C = 12x- 3  and y = 7x - 2

It is given that angles r and s are complementary  angles. Two angles are complementary  if they add up to 90 degrees. This means the sum of measures of angle r and angle s must be 90 degrees. So,

c + y = 90

12x - 3 + 7x - 2 = 90

19x - 5 = 90

19x = 95

x = 95/19

x = 5

Using the value of x in expression or r, we get:

c = 12x - 3 = 12(5) - 3 = 60 -3 = 57 degrees.

So measure of angle c is 57 degrees.

Hence, the ∠ is 57 °

The standard equation of an ellipse is [tex]\frac{x^2}{144} +\frac{y^2}{95} =1[/tex]

The standard equation of an ellipse is given by:

[tex]\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} =1[/tex]

Where (h, k) is the center of the ellipse, 2a is the length of the major axis and 2b is the length of the minor axis.

Given the center = (0, 0), a = 12, b = 9.75, hence:

[tex]\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2} =1\\\\\frac{(x-0)^2}{12^2} + \frac{(y-0)^2}{9.75^2} =1\\\\\frac{x^2}{144} + \frac{y^2}{95} =1[/tex]

Step-by-step explanation:

q and u are the only congruent angles

Function represents a relationship between variables. The product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.

A function assigns the value of each element of one set to the other specific element of another set.

Given to us

k(x) = 2x² − 7

p(x) = x − 4

As the two equations are given to us, k(x) and p(x), and we need to find (k ∘ p)(x), And we know the product of two functions can be written as,

[tex](k \cdot p)(x) = k(x) \cdot p(x)[/tex]

therefore,

[tex]k(x) \cdot p(x)\\\\= (2x^2-7)(x -4)\\\\= 2x^3 - 8x^2 - 7x +28[/tex]

Hence, the product of the two given functions (k·p)(x) is 2x³-8x²-7x+28.

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the height and b₁, b₂ the parallel bases

here h = 12 and b₁ = 14, b₂ = 24 , then

A = [tex]\frac{1}{2}[/tex] × 12 × (14 + 24) = 6 × 38 = 228 ft²

Answer:

To find an inverse function, reflect a graph of a function across the line y=x (and find the resulting equation)

To reflect a linear function in the line y=x, find points on f(x) and then swap their x and y coordinates.

Points on f(x):  (0, -4)  (2, 0)  (5, 6)

Points reflected in line y=x:  (-4, 0)  (0, 2)  (6, 5)

Plot points (-4, 0)  (0, 2)  (6, 5) and connect to form a straight line - this is the inverse of the function:  [tex]f^{-1}(x)[/tex]

To determine the equation of f(x):

Choose 2 points on f(x):  (5, 6) and (0, -4)

Calculate the slope (gradient) by using:

[tex]m=\dfrac{\triangle y}{\triangle x}=\dfrac{y_2-y_1}{x_2-x_1}=\frac{6--4}{5-0}=2[/tex]

Using the slope-intercept form:  y = mx + b

(where m is the slope and b is in the y-intercept)

From inspection of the graph, we can see the line crosses the y-axis at -4,

⇒ f(x) = 2x - 4

As the line is actually a line segment (with endpoints (0, -4) and (5, 6), then

f(x) = 2x - 4,   0 ≤ x ≤ 5

To determine the equation of [tex]f^{-1}(x)[/tex]:

Rewrite f(x)  as  [tex]y = 2x - 4[/tex]

Swap the x and y:  [tex]x = 2y - 4[/tex]

Rearrange to make y the subject: [tex]y= \dfrac{1}{2}(x + 4)[/tex]

Replace y with [tex]f^{-1}(x)[/tex]

So the equation of the inverse is:   [tex]f^{-1}(x)= \dfrac{1}{2}(x + 4)[/tex]

As the original function is a segment, then

[tex]f^{-1}(x)= \dfrac{1}{2}(x + 4), \ \ \ -4\leq x\leq 6[/tex]

(shown in blue on the attached diagram)

** I can't see any points labelled E and F on the original function. If they are the endpoints of the line segment of f(x), then they are (0, -4) and (5, 6) **

Answer:

The initial height is the y-intercept of the graph

slope of the graph = -2

Jordon interprets the only the slope correctly.

Aral interprets the only the initial height correctly.

Step-by-step explanation:

Slope = change in y ÷ change in x = (0 - 12) ÷ (6 - 0) = -12 ÷ 6 = -2

So the slope of the graph = -2

by inspection, the y-intercept = 12

Therefore, the equation for the line is   y = -2x + 12

Jordon interprets the only the slope correctly.

Aral interprets the only the initial height correctly

Answer: 150km

Step-by-step explanation:

The question says that the car required 9 litres of gasoline to cover 108km which means we and then derive that:

9L = 108km

And we are trying to find out how much distance can cover:

12.5L =?

Therefore, in order to find out the distance, we need to figure out how much distance can 1L take the car

therefore:

1L = [tex]\frac{108km}{9L}[/tex] = 12km

So if we know how far 1L can take us, we can just multiply 12.5 litres by the 12km to find out the distance:

12.5L × 12km = 150km

So, therefore, 12.5 litres can cover 150km.

True.

[tex]10^{10}[/tex] = 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.

Answer:

The total weight is 1593 lbs.

Step-by-step explanation:

177*9 = 1593

The y-intercept of g(x) is equal to 2 plus the y-intercept of f(x).

The functions are given as:

f(x) = -2(1.07)^x

Table of values for g(x)

x    g(x)

−4    −10

−2 −    7

0        −4

2         1

The y-intercept is when x = 0.

So, we have:

g(0) = -4

Also, we have:

f(0) = -2(1.07)^0

f(0) = -2

-2 is greater than -4 by 2

Hence, the y-intercept of g(x) is equal to 2 plus the y-intercept of f(x).
