The region between the graphs of X = y2 and X = 5y is rotated around the line y=5. The volume of the resulting solid is_________

ICE Princess25 [194]

Answer and Step-by-step explanation:

The volume of the resulting solid is shown below:-

The lines in for

y can be y = sqrt(x) using square root

and y = x ÷ 5

In this, the intersect is done when sqrt(x) = x ÷ 5 using square root

Now

x = x^2 ÷ 25

x = 0

x = 25

so outermost is x ÷ 5 innermost is sqrt(x) using square root

Therefore A is

= integral of pi ( (x ÷ 5-5)^2 - (sqrt(x)-5)^2) using square root

from 0 to 25

= 625 pi ÷ 6

Find the value of x.

lawyer [7]

Answer:

$\huge\boxed{x=\sqrt{70}}$

Step-by-step explanation:

ΔABC and ΔADB are similar (AAA).

Therefore the corresponging sides are in proportion:

$\dfrac{AB}{AD}=\dfrac{AC}{AB}$

Substitute:

$AB=x\\AC=7+3=10\\AD=7$

$\dfrac{x}{7}=\dfrac{10}{x}$ cross multiply

$(x)(x)=(7)(10)\\\\x^2=70\to x=\sqrt{70}$

HELP PLEASE Which of the following graphs is not a function

Luden [163]

A simple rule to tell whether a graph is a function is to pretend to cut it vertically, if any cut intercept the graph twice, it is not a function. otherwise, it is.
In this case, the heart is not a function, because if you cut it up-down direction, your imaginary knife will touch the edge of the heart twice.
I hope this explanation helps.
