(f o g)(x)=
stick g(x) in for x in the function f(x)
(f o g)(x)= 4(g(x)) -1
=4*5x^2 -1
= 20x^2 -1
Answer:
Option B is the correct answer.
Step-by-step explanation:
The cost in dollars, c, of renting a carpet cleaner is given by the linear equation. C = 20+25x, where x is the number of days.
Here we need to find cost of carpet cleaner for 11 days.
That is x = 11 days
Substituting in C = 20+25x
C = 20+25 x 11 = 20 + 275 = 295 $
Cost for renting the unit for 11 days = 295 $
Option B is the correct answer.
Answer:
the third one
Step-by-step explanation:
<span>If temperature can be estimated by counting cricket chirps and applying it to a given formula, a cricket that chirps 164 times in one minute indicates that it is approximately 78 degrees Fahrenheit (B).</span>
It's pretty much combining a lot of addition into a smaller equation. For example, if you don't want to write it all out like 7+7+7+7+7+7+7=49, then you can condense it to 7*7=49. Another example is 6+6=12 is the same as writing 6*2=12.
