Answer:
1) A , 2) C , 3) D
Step-by-step explanation:
Answer:
Slope is rise over run. To calculate rise over run you go from a point to the next. In your case, the rise over run is 1000/1. So your rate of change is 1000. Your y-intercept form equation is y=1000x+0, because 0 is the y-intercept.
0x1000+0=0
1x1000+0=1000
2x1000+0=2000.
3x1000+0=3000
So, if it's asking what time the balloon is at 5000 ft, you do 5000/1000=5. (you'd divide by your rate of change because division is opposite of multiplication). So, at 5 minutes, the balloon will be at 5000 ft.
Since 2 seconds is 1/30 of a minute, you do 1/30 to get .03. .03x1000+0= 30.
This means the balloon will be 30 feet in the air at 2 seconds.
The balloon will reach 10,000 ft at 10 minutes. You take the feet and divide by the slope. 10,000/1000 = 10 and 10x1000+0=10,000
The answer is D because the function is a cubic function. if you graph for example, x³, it would be in Q. 1 and 3
Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
The median or the mode which is three, but not the average because there is an outlier in the set, which is 19 and would skew the data higher than it should be.
