Answer:
D) 4x2+4x=4
Step-by-step explanation:
3x2+x2=4x2
-x+5x=+4x
2-6=-4
Combine them for 4x2+4x-4
there are 4 methods to do it
if 3 of it's angles are same
if all the sides are same
if 2 angles and 1 side are same
if 2 sides and 1 angles are same
The function would be h = 270 - 2.5s, where h is the height (in feet) and s it the time (in seconds) that has passed.
The 270 represents the initial value, which is given. We are told that the initial height of the block is 270 feet.
2.5s represents the feet that it has descended. We know the block is lowered at a rate of 2.5 feet per second. Multiplying this by s, the time, will give us how much it has descended.

Answer:
a[n] = (-1/3)^(n -1)
Step-by-step explanation:
The terms have a common ratio of (-1/3)/(1) = -1/3. The general term for a geometric sequence with first term a1 and common ratio r is ...
a[n] = a[1]×r^(n-1)
Here, a[1] = 1, so this is ...
a[n] = (-1/3)^(n-1)
