Answer:
B) 686 cubic units
Step-by-step explanation:
If one cube has a side length of 7, then it equals to 343 cubic units. Since there are 2 cubes, this translates to 686 cubic units.

Step-by-step explanation:
<u>Step 1: Define</u>
w(n) = n² + 6
w(-9) is n = -9
<u>Step 2: Evaluate</u>
- Substitute: w(-9) = (-9)² + 5
- Exponents: w(-9) = 81 + 5
- Add: w(-9) = 86

Answer:
t = 3.5 sec
Step-by-step explanation:
The equation that represents the position of the ball as a function of time is the following:
Where:
= Initial position of the ball (4 feet tall)
= Initial speed of the ball (55feet / s)
a = acceleration (9.8 , or in this case 32.16)
t = time in seconds
Then we want to know how long it takes to get to the ground, for this we equal h (t) = 0 and clear t.
So:
Solving the second degree equation we have:
t = -0.071 sec
t = 3.5 sec
We must take the positive solution.
So:
t = 3.5 sec
