-9-(12-3x)=-9-1*(12)-1*(-3)=-9-12+3x=-21+3x=3(x-7)
So we have -23 degrees to start
Then add 5 to it
It becomes -23+5=-18
Now subtract 7 from that so -18-7=-25 degrees
Hope this helps
The rule of geometric sequence is ⇒⇒⇒ a * r^(n-1)
Where a is the first term and r is the common ratio
for the given sequence √5 , √10 , 2√5 , .......
a = √5
r = √10 / √5 = √2
The ninth term = √5 * (√2)^(9-1) = √5 * (√2)⁸ = 16 √5
the correct answer is the third option 16√5
Answer: The answer is √6 mi.
The formula is: d = √(3h/2)
Pam:
h = 324 ft
d = √(3 * 324/2) = √486 = √(81 * 6) = √81 * √6 = 9√6 mi
Adam:
h = 400 ft
d = √(3 * 400/2) = √600 = √(100 * 6) = √100 * √6 = 10√6 mi
How much farther can Adam see to the horizon?
Adam - Pam = 10√6 - 9√6 = √6 mi
