Answer:
If lava cools slowly and does not move too fast it forms smooth ropy lava called pahoehoe.
However, if it cools quickly and moves fast it can tear into clinkery pieces called a'a
Answer:
fog(1) = 25
g(h(-2)) = 10
Explanation:
Given the following functions
f(x) =x^2,
g(x) =5x,
h(x)=x+4
We are to find;
i) fog(1)
fog = f(g(x))
f(g(x)) = f(5x)
f(5x) = (5x)²
f(5x) = 25x²
f(g(x)) = 25x²
f(g(1)) = 25(1)²
f(g(1)) = 25
Hence fog(1) is 25
ii) g(h(x))
= g(x+4)
g(x+4) = 5(x+4)
g(x+4) = 5x+20
g(h(x)) = 5x + 20
g(h(-2)) = 5(-2)+ 20
g(h(-2)) = -10 + 20
g(h(-2)) = 10
I believe that the answer is A.
I'm not 100% sure... But I think D Are Cold Currents. Again, I'm not 100% sure.
