Answer:
the answer of the above question is -1.2
Answer:
$700
Step-by-step explanation:
Given that:
Cost of desktop PC 10 years ago = $6000
Cost of desktop PC 2 years ago = $300
Linear model applies.
To find the rate of decrease per year, we need to find the slope.
One quantity is cost of PC here and second quantity here is number of years.


So, the answer is:
There is a decrease of <em>$700 </em>per year.
OR
Rate of decrease per year is <em>$700</em>.
Answer:
x ≈ 30.7
Step-by-step explanation:
Reference angle = 61°
Opposite side length = x
Adjacent side length = 17
Applying the trigonometric function TOA, we have:
Tan 61 = opp/adj
Tan 61 = x/17
17 × Tan 61 = x
x ≈ 30.7
10 feet 6 inches = 126 inches. Length of the car is 126 inches and the model length is 7 inches.
126 : 7 = 18
The scale factor of the model to the actual car is 1 : 18.
