Step-by-step explanation:
3x-5=8x-60
55=5x
x=11
The solution would be like
this for this specific problem:
<span>V = ∫ dV </span><span>
<span>= ∫0→2 ∫
0→π/2 ∫ 0→ 2·r·sin(φ) [ r ] dzdφdr </span>
<span>= ∫0→2 ∫
0→π/2 [ r·2·r·sin(φ) - r·0 ] dφdr </span>
<span>= ∫0→2 ∫
0→π/2 [ 2·r²·sin(φ) ] dφdr </span>
<span>= ∫0→2 [
-2·r²·cos(π/2) + 2·r²·cos(0) ] dr </span>
<span>= ∫0→2 [
2·r² ] dr </span>
<span>=
(2/3)·2³ - (2/3)·0³ </span>
<span>= 16/3 </span></span>
So the volume of the
given solid is 16/3. I am hoping that these answers have satisfied
your query and it will be able to help you in your endeavors, and if you would
like, feel free to ask another question.
Answer:
a) y = 4.5
Step-by-step explanation:
y intercept is where the line crosses the y axis. so y must be 4.5
Answer:
hypotenuse = aprox 18.6
Step-by-step explanation:
a^2 + b^2 = c^2
11^2 + 15^2 = c^2
346 = c^2
square root both sides
c = aprox 18.6
hope that helped!
