360 degrees because it would rotate all the way back on to itself, 90 and 45 degrees wouldn't rotate it far enough, and 180 degrees would just flip it
Answer:
1/2
Step-by-step explanation:
This midpoint is found by averaging -4 and 5:
-4 + 5

Answer:
Her initial position was:
-29ft
Where we use the minus sign because this is below the ocean's surface.
Now we also know that she keeps descending at a rate of -29ft per minute, then if she keeps descending for t minutes, her position will be:
P(x) = -29ft - 29ft/min*t
Now, we also know that she does not want to descend more than 81ft below the ocean's surface, then we have the inequality:
P(x) ≥ -81ft
-29ft - 29ft/min*t ≥ -81ft
Now let's isolate t in one side:
- 29ft/min*t ≥ -81ft + 29ft = -52 ft
- 29ft/min*t ≥-52 ft
t ≤ -52ft/(- 29ft/min) = 1.79 min
Then the maximum amount of time that she can keep descending is 1.79 minutes.
Answer:
23
Step-by-step explanation:
just count the squares in side box
The function given in the question is
The question asks to find the expression for
To get the expression for f(a+2), we will substitute the value of x = a+2
By substitution, we will have
Expanding the brackets, we will have
Therefore,
The expression for f(a+2) is
f(a+2) = a² + 2a + 1
