The answer is 4x-8+4y i think?
Answer:
48
Step-by-step explanation:
0.8 times 60= 48
A total of 440 students took part in the survey. Each student makes up 0.8181818182% of the central angle of the circle graph. You get to this number by dividing 360 degrees by 440 students. Then you simply multiply this number by 110 students (who liked the program).
0.8181818182%*110=90 degrees
Answer:
p(t) = 100%·2^(-t/1.32)
Step-by-step explanation:
The equation for exponential decay is ...
(remaining amount) = (initial amount)·2^(-t/(half-life))
Here, we can represent the percentage remaining by p(t) and the initial amount by 100%. Then, for a half-life of 1.32 minutes, the amount remaining is ...
p(t) = 100%·2^(-t/1.32) . . . . . where t is in minutes
_____
Alternate functional forms are possible, such as ...
p(t) = 100%·e^(-0.525112t)
p(t) = 100%·0.591489^t
Answer:
C
Step-by-step explanation:
For the first one, there is a ratio of change greater than one so that is exponential growth.
The second one has exponential decay but its x is negative making it actually exponential decay even if graphed.
The third one has positive growth over an interval of negative x, so in terms of x there is exponential decay.
The fourth one is neither and if graphed is just points as there is a specific solution set.
In conclusion, the third is exponential decay!
Hope this helps :)
