Answer:
V = 2458.10 cubic inches
Step-by-step explanation:
Volume of a cylinder
V = πr^2h
V - volume of the cylinder
π - pie
r - radius of the cylinder
h - height of the cylinder
Given :
π - 3.142
h - 19.1 inches
d - 12.8 inches
Calculate the radius
Diameter = 2 * radius
Radius = diameter/2
r = 12.8/2
= 6.4 inches
Find the volume
V = 3.142 * (6.4)^2 * 19.1
= 3.142 * 40.96 * 19.1
= 2458.0997 cubic inches
To nearest tenth
V = 2458.10 cubic inches
Answer: 2.3
Step-by-step explanation:
answer: the system had no solution
Answer:
Step-by-step explanation:
Begin by dividing by 5
2x + 4 = 3
Is this written as 2^(x + 4) = 3? I think it is.
Take the log of both sides
log 2^(x + 4) = log(3)
(x + 4) * log(2) = log 3
log 2 = 0.30103
log 3 = 0.47712
(x + 4) = log2 / log3
x + 4 = 0.63093 Add 4 to both sides
x = -3.369 Rounded to the nearest thousandth
====================
If you mean the question exactly as it is written (the 4 is not part of the power)
5(2^x + 4) = 15
2^x + 4 = 3
2^x = 3 - 4
2^x = - 1
This can't be done 2 to any power should be >0.
if x>0 then this will give an ever increasing number
if xK0 then this will give an ever decreasing answer but still greater than 0.
No value will make 2^x go to something minus.
If I have misread this in some way, leave a note and I will get back to you.
