Answer:

f(g(x)) =  5x^{2}   + 10x+ 5

Step-by-step explanation:

Here, the given functions are:

f(x)  = 5x^2\\g(x) = x+1

Now, (fg)(x)  = f (g(x))

f(g(x))= f (x+1)

\implies f(x+1)  = 5(x+1)^2

By ALGEBRAIC IDENTITY:

(a+b)^2  = a^2 + b^2  + 2ab\implies (x+1)^2  = x^{2}  + 1 + 2x

So, 5(x+1)^2   = 5(x^{2}  + 2x + 1)  = 5x^{2}   + 10x+ 5

Hence, f(g(x)) =  5x^{2}   + 10x+ 5

Find the distance between the two points (0,0), (4,3)
Amiraneli [1.4K]

Answer:

Distance between the points=5

Step-by-step explanation:

The distance between two points in coordinate geometry is measured by using the distance formula:

If we have given two points

                   (x_1,y_1)\\\\(x_2,y_2)

Distance formula=  \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

For (0,0) and (4,3)

      Distance:                          

                        \sqrt{(4-0)^2+(3-0)^2} \\\\\sqrt{4^2+3^2}\\\\\sqrt{16+9}\\\\\sqrt{25}

Or

      Distance between the points=5

Adjacent angles and linear pairs can you help?
Natalija [7]

Answer:

Step-by-step explanation:

x + 13 + 4x + 2 = 180

Add the like terms,

5x + 15 = 180

Subtract 15 form both sides

5x + 15 - 15 = 180 -15

5x = 165

Divide both sides by 5

5x/5 = 16/5

x = 33
