Divide both sides by 4
e^(2.7x) = 8.25
Take natural logarithm of both sides
2.7x = ln 8.25
x = (ln 8.25)/2.7 = ln (8.25^(1/2.7))
Answer:
(-2,8) and (2,-8)
the second is a reflection across the x axis
the third is a reflection across the y axis
this just reverse the points, i'm not sure if it's anything

Answer:
r = 6 cm
Step-by-step explanation:
The volume of a sphere is 288 pi cm tripled . Find the lenght of a radius of a SPHERE.What is the answer and how did you do it?
-------------------
The volume of a sphere of radius r is:
V+=+4%2Api%2Ar%5E3%2F3
It's r cubed, not tripled. meaning r*r*r
-------------------
288pi+=+4%2Api%2Ar%5E3%2F3
864+=+4r%5E3
r%5E3+=+216
r = 6 cm
