Distance: sqr (x1-x2)^2 + (y1-y2)^2
Sqr (5-7)^2 + (-6-1)^2
Sqr (-2)^2 + (-7)^2
Sqr (4) + (49)
Sqr (53)
= 7.28

Find the domain of the function (ƒ • g)(x) where ƒ(x) = 2x2 + x, g(x) = 5x – 1

asambeis [7]

Not sure if that's a multiplication or a composition. It doesn't matter. Both f and g have a domain of all real numbers. The domain of

$( f \circ g)(x)=f(g(x))$

is the same as the domain of g(x), all real numbers

Answer: all real numbers

Express: 0.006 in exponeutialform

Yuri [45]

6×10^-3

Step-by-step explanation:

0.006

Move the point to the front of the first number that is from 1 to 9.

In the question it's 6, so you move it to the front of 6 .

And because it's from back to front it has to have a negative sign in its power

which is going to be

6× 10^-3

where 6=the number from 1 to 9

^ means raise to power or power of

-3= the negative power

The volume of a cylinder is $1178.1 \ cm^3$

Explanation:

Given that the diameter of the cylinder is 10 inches.

The radius of the cylinder is given by

$r=\frac{d}{2}$

$r=\frac{10}{2} =5$

Thus, the radius is 5 inches.

Also, given that the height is three times the radius.

Thus, we have,

$h=3r$

$h=3(5)$

$h=15$

Thus, the height is 15 inches.

The volume of the cylinder is given by

$V=\pi r^{2} h$

Substituting the values, we get,

$V=\pi (5)^{2} (15)$

$V=\pi (25) (15)$

$V=375 \pi$

Using the calculator, the value of pi is determined and multiplied with 375.

Hence, we have,

$V=1178.1 \ cm^3$

Thus, the volume of the cylinder is $1178.1 \ cm^3$
