The scale factor is 3. Convert the feet to inches which is: 9 ft.= 108 in. Then, you divide 108 by 36 which equals 3. (I'm assuming that 36 is the length)
Hope this helps!
Ask the question better, or include PT1 and I'll answer it better
(f.g)(x) = f (g(x))= f ( x^4+3)
= (x^4+3)^2 + 2 ( x^4+3) - 6
= x^8 + 9 + 6x^4 + 2x^4 + 6-6
= x^8 + 8x^4+9
Answer:
<em>It will take 9 years for the population to double</em>
Step-by-step explanation:
<u>Exponential Growth
</u>
The natural growth of some magnitudes can be modeled by the equation:

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.
The population of a city grows at a rate of r=8% = 0.08 per year. We are required to find when (t) the population will double, or P=2Po.
Substituting in the equation:

Simplifying:

Taking logarithms:

Applying the exponent property of logs:

Solving for t:

Calculating:

It will take 9 years for the population to double
Answer:
-2x + 4y - 2z
Step-by-step explanation:
as you can see, the graph indicates which axis belongs to x, y, and z and also gives information on the positive and negative directions of each axis.
to get the answer, all you have to do is find each coordinate,
x is at -2, y is at +4, and z is at -2.
