Aclimber is on a hike . after 2 hours he is at an altitude of 400 feet after 6 hours he is at an altitude of 700 what is the average rate of change (show your )

Step-by-step explanation:

Rate of change = Δy/Δx

Let x = time in hours and y = altitude in feet

Δx = 6 hours - 2 hours = 4 hours

Δy = 700 feet - 400 feet = 300 feet

ROC = 300 feet/4 hours = 75 feet/hour.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.

he spend 5.1 minutes chatting with his friends.

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1
