We know that
[volume of a square pyramid]=area of the base*height /3
area of the base=3*volume/height
volume=245 in³
height=15 in
area of the base=3*245/15-------> 49 in²
the area of the base is a square
so
area=b²---------> b=√area---------> b=√49-------> b=7 in
the answer is
T<span>he length of one side is 7 in</span>
The leftmost line segment has a domain of -4 ≤ x < -1, or [-4, 1).
The central line segment has a domain of -1 ≤ x ≤ 2, or [-1, 2].
The rightmost line segment has a domain of 2 < x ≤ 5, or (2, 5].
Overall, this function has a domain of
[-4, 1) U [-1, 2] U (2, 5]
(where U means "union" in the set-theoretic notion)
But this also simplifies to the interval [-4, 5].
These correspond to the <u>first</u> and <u>last</u> choices.

Answer:
4.81 x 10^13
Step-by-step explanation:
Just count how many numbers there are and subtract it by one for the exponent, and put the decimal behind the first number.
Mike's withdrawals will be treated as negative numbers.
Since Mike withdrew $60 three times, use the following equation to find the change in his balance:
The change in Mike's account balance will be
-$180.
