Answer:
B. 2,433,400 m^3
Step-by-step explanation:
V = (1/3)Bh
where B = area of the base of the pyramid, and
h = height of the pyramid
B = s^2 = (230 m)^2
h = 138 m
V = (1/3)(230 m)^2(138 m)
V = 2,433,400 m^3
Answer:
Step-by-step explanation:
I believe you meant to write
?
If that's the case I'll solve the one I provided but I'll drop the base 2 to type it faster but you need to put it always!
Remember: log a + log b = log (a*b)
So log (x+2) + log (x-2) = log [(x+2)*(x-2)] = log (x^2 - 4)
Now back to the inequality:
log (x^2 - 4) <span>≤ log 5
Raise both sides as powers of 2 ( Since it's the base of your log)
Now,
x^2 - 4 </span><span>≤ 5
Add 4 both sides:
x^2 </span>≤ 9
Square root both sides
x ≤ +3 or x ≤ -3
Reject the -3 solution as it makes both (x + 2) and (x - 2) negative and a log can never have a negative value inside its brackets.
So x <span>≤ 3 But can never be less than 2 as well for the same previous reason.
Hope that helped.</span>
Can you say exactly what your asking for.
the ansewer is y=-1/2<span>x-1</span>
