Answer:
-127
Step-by-step explanation:
u(x)=2x-2
w(x)= -2x^2+1
w(u(5))=?
---------
u(5)= 2*5-2= 8
W(8)= - 2*64+1= -127
Answer:
none of the above
f(x) ≈ 197·1.03^x; approximately 3% daily
Step-by-step explanation:
If we let x represent days, then x/7 represents weeks and we can rewrite f(x) as ...
f(x/7) = 197·1.25^(x/7) = 197·(1.25^(1/7))^x
f(x) ≈ 197·1.03^x
__
The daily multiplier of 1.03 represents a daily growth rate of
1.03 -1 = .03 = 3%
_____
These answers are not found among the offered choices:
f(x) = 197·1.03^x
3% daily growth
Step-by-step explanation:
6 = x; 3 in. is the MIDPOINT, so it's ALWAYS going to be dilated ½ of what you want.
Answer:
65.5 feet per second
Step-by-step explanation:
In order to calculate the rate of descent we first need to find the difference in heigh that the hot air balloon descended. We do this by subtracting the initial height from the end height like so...
6,039 - 3,288 = 2,751 ft
Now that we have the difference in height we need to divide this by 42 since that is the amount of time it took for this descent to occur.
2,751 ft / 42s = 65.5 ft/s
Finally we can see that the rate of descent was 65.5 feet per second
It should be this y=1/2x+3
