Answer:
-56
Step-by-step explanation:
Hello!
Let's create an equation to figure out what the middle integer really is.
Creating an equation:
n + (n + 1) + (n + 2) = -168 (This is true because we must account for the <em>consecutive integers </em>part.)
Simplifying:
3n + 3 = -168
Subtracting:
3n = -171
Dividing:
n = -57
Now, we plug-and-chug:
-57, -56, -54 (this is because we accounted for adding <em>positive </em>one.)
Thus, the middle integer is .
Check:
We can see if we are correct by adding up -57, -56, -54.
(-57) + (-56) + (-54) = -168
So we are correct!
Hope this helps!
Answer:
144 π cubic meters
Step-by-step explanation:
Formula for surface area of sphere is :
S = 4*π* r^2
We know the volume V = 288*π cubic meters.
V = (4/3)*π*r^3
288*π = (4/3)π*r^3
Solve for r.
(3/4)*288 = r^3
r = 6 meters
S = 4 *π*6^2 = 4*36 * π = 144 π cubic meters

Answer:
Replace the variable x with −1
in the expression.
f(−1)=−(−1)²−1
Simplify −(−1)²−1.
Remove parentheses.
−(−1)²−1
Multiply −1 by (−1)²
by adding the exponents.
(−1)³−1
Raise −1 to the power of 3.
−1−1
Subtract 1 from −1.
−2
