Answer:
-140 feet
Step-by-step explanation:
The relation between speed, distance, and time can be written ...
distance = speed × time
distance = (28 ft/s)(5 s) = 140 ft
In 28 seconds, the skydiver changed position by 140 feet. Since the direction is presumed to be down (falling), the change in altitude is -140 feet.
Answer:
4a^2b-8ab^2
Step-by-step explanation:
Answer + Explanation
You look at the two denominators of the fractions and find the least common multiple of both of them.
1. the LCM of 2 and 5 is 10
2. the LCM of 3 and 5 is 15
3. the LCM of 4 and 6 is 12
4. the LCM of 6 and 9 is 18
There are 2 ways to do this...
19,500(1.06) = 20,670
or
19,500 + 0.06(19,500) = 19,500 + 1170 = 20670
Step-by-step explanation:
f(x) = x² - 4
g(x) = 7 - x
= (fog)(2)
= x² - 4
= (7 - x)² - 4
= (7 - 2)² - 4
= 5² - 4
= 25 - 4
= 21
(fog)(2) = 21
