Answer:
The last choice: -√2 + 8√6.
Step-by-step explanation:
4√24 - 4√8 + √98
= 4* √4*√6 - 4*√4√2 + √49*√2
= 8√6 - 8√2 + 7√2
= 8√6 - √2
= -√2 + 8√6.
A scuba diver was exploring a
reef 32.12 m below sea level. The diver ascended to the surface at a rate of
8.8 m/min.
a. using the formula d = rt,
so 32.12 m = 8.8m/min (t)
b. it is reasonable to write
the distance as positive because the diver is accending/ going up the surface
<span>c. t = 32.12/ 8.8 = 3.65 min</span>
