Answer:

if g(n)=n2+2

you asked g(3)

by substituting the value we get

g(3)=3×2+2

g(3)=6+2

g(3)=8

so the answer is 8

What is the slope of a line perpendicular to the line whose equation is 3x+6y=-183x+6y=−18. Fully reduce your answer.

schepotkina [342]

Answer:

Step-by-step explanation:

The given equation of line is

$3x+6y=-18$

We need to find the slope of a line which is perpendicular to the given line.

The given equation can be rewritten as

$3x+6y+18=0$ ...(i)

If a line is defined as $ax+bx+c=0$ , then the slope of the line is

$m=-\dfrac{a}{b}$

In equation (i), a=3, b=6 and c=18. So, slope of the line is

$m_1=-\dfrac{3}{6}=-\dfrac{1}{2}$

Let $m_2$ be the slope of perpendicular line.

We know that product of two perpendicular line is -1.

$m_1\cdot m_2=-1$

$(-\dfrac{1}{2})\cdot m_2=-1$

Multiply both sides by -2.

$m_2=2$

Therefore, the slope of perpendicular line is 2.

Five spheres are being painted for a display at a store. If the diameter of each sphere is

ivanzaharov [21]

<h2>Hello!</h2>

The answer is:

The total area is:

$TotalArea=192.4cm^{2}$

To find the cloasest value to the total surface area that will be painted, we need to calculate the area of a single sphere, and then, multiply it by 5.

We know that the diameter of each sphere is 7 centimeters, so, calculating we have:

Calculating the radius we have,

$diameter=2*radius\\\\radius=\frac{diameter}{2}=\frac{7cm}{2}=3.5cm$

Then, calculating the area, we have:

$Area=\pi radius^{2}$

$Area=\pi 3.5cm^{2}=38.49cm^{2}$

Now that we have calculated the surface area of a single sphere, we need to calculate the area of the five spheres.

So, calculating we have:

$TotalArea=5*38.48cm^{2}=192.4cm^{2}$

Hence, the total area is:

$TotalArea=192.4cm^{2}$

Have a nice day!

If y=3x+5 and z=x^2+2x-5, what is yz?

Hitman42 [59]

<h3>Answer: 3x^3 + 11x^2 - 5x - 25</h3>

Work Shown:

yz = y(x^2+2x-5)

yz = y(x^2) + y(2x) + y(-5)

yz = x^2( y ) + 2x( y ) - 5( y )

yz = x^2( 3x+5 ) + 2x( 3x+5 ) - 5( 3x+5 )

yz = x^2*3x + x^2*5 + 2x*3x + 2x*5 - 5*3x - 5*5

yz = 3x^3 + 5x^2 + 6x^2 + 10x - 15x - 25

yz = 3x^3 + 11x^2 - 5x - 25
