Answer:
P= 20x+2 ft
Step-by-step explanation:
________
I I
I I 3x + 7ft
________
7x - 6ft
P= (7x - 6 + 7x - 6) + (3x + 7 + 3x + 7)
= (14x - 12) + (6x + 14)
= 20x + 2 ft
Answer:
b $.05
Step-by-step explanation:
5 lbs is .80 and 8 lb is .75 so a 5 cent difference per lb
Answer:
A) 1/45
B) 1/60
Step-by-step explanation:
<u>Part A</u>
The actual car has a length to width ratio of ...
length/width = (570 cm)/(180 cm) = 57/18 = 3 1/6
The rectangle on the screen has a length to width ratio of ...
length/width = (13 cm)/(4 cm) = 3 1/4
Relative to its width, the screen rectangle is longer than necessary for a model of the car. So, the scale factor will be determined by the width of the car relative to the width of the screen model.
For a model width of 4 cm, the scale factor is ...
model/life-size = (4 cm)/(180 cm) = 1/45
__
<u>Part B</u>
For a model width of 3 cm, the scale factor is ...
model/life-size = (3 cm)/(180 cm) = 1/60
Answer:
The answer to this is SAS
Answer:
transformed function, g (x) = (1/5)(-x)+7
Step-by-step explanation:
Assuming
f (x) = -x (and not f(x)-=x)
To compress/expand, we apply
g (x) = a*f(bx-k)+h
where
a=vertical stretch factor, a= 1/5 for compression (to stretch 5 times, a=5)
b=horizontal compression factor (=1 i this case)
h=vertical translation (=7)
k=horizontal translation (=0)
So the transformed function,
g (x) = (1/5)(-x)+7
