16 + (-8) = 8 <== here is one
16 - 8 = 8
8 = 8 (correct)
-12 + 20 = 8 <== and another
11 + (- 3) = 8 <== and another
4th term = 29
to generate the terms, substitute n = 2, 3, 4 into the rule
noting that b(1) = - 7
b(2) = b(2 - 1) + 12 = b(1) + 12 = -7 + 12 = 5
b(3) = b(3 - 1) + 12 = b(2) + 12 = 5 + 12 = 17
b(4) = b(4 - 1) + 12 = b(3) + 12 = 17 + 12 = 29
Answer:
Step-by-step explanation:
when a rotation of 180 ° happens, it switches the (x,y) coordinates from (x,y) to (-x,-y) .. that's alll... soo for M then, of (3,4) it switches to M ' = ( -3, -4) see?
Answer: 8.73 ft/s
Step-by-step explanation:
We have the following equation that models the motion of the rock:
Where 
is the height of the rock at a time 
.
Now, if 
we can find and then the velocity of the rock at that height:
Rearranging the equation:
Multiplying the equation by -1:
Solving with the quadratic formula 
, where 
, 
, 
.
Choosing the positive result of the equation:
Since velocity 
is defined as the traveled distance in a given time , we have:
This is the velocity of the rock at the height of 48 feet
