Awall that is 12 feet high on the building is 36 centimeters high on the model. find the height on the model of a door that is 9 feet high on the building.
i already solved this one. the answer is 27. im having trouble with part b.
(b) find the number of centimeters on the model for a window that is 3 feet wide.

9 centimeters

Step-by-step explanation:

Hi, to answer this question we have to apply the same ratio applied to find the height in centimeters of the door.

12ft/36cm = 9ft/x cm

12/36= 9/x

x = 9/ (12/36)

x =27cm

Using the value of the window's wide instead of the door's height.

12/36 = 3/x

x = 3 / (12/36)

x = 9cm

Feel free to ask for more if needed or if you did not understand something.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024

you,
