Answer:

\boxed{\sf \ C \ is \ the \ correct \ answer \ ! \ }

Step-by-step explanation:

fog(x)=f(g(x))

so it comes

f(g(x))=f(x+1)=4(x+1)^2

<u>so C is the correct answer</u>

Answer:

Option B

Step-by-step explanation:

f(x) = 4x^2\\g(x) = x+1

Multiplying both will give us:

(fg)(x) = 4x^2(x+1)

=> (fg)(x) = 4x^3+4x^2

How to make 2700 and 600 a fraction
devlian [24]
I think I may be missing something ... I don't completely understand your question. 
All you need to make a fraction is two numbers and a bar.  The bar can be either
horizontal or slanty.  Then you write one number on top and the other number on
the bottom, and bada-bing, you have a fraction.

You can make fractions like

             2700 / 600
                 27 / 6         
                   9 / 2           (all 3 of these have the same value)

             600 / 2700
                 6 / 27         
                 2 / 9              (all 3 of these have the same value)

You want to calculate the displacement of an object thrown over a bridge. Using -10 m/s^2 for acceleration due to gravity, what
MrRissso [65]

<u>Answer</u>

<em>The total displacement of the object is 320 m</em>

<u>Solution-</u>

From the formulas of mechanics,

s=ut+\frac{1}{2}at^{2}

Where,

s = displacement

u = initial velocity = 0               ( ∵ As the body was in rest in the beginning )

t = time taken = 8 s

a = acceleration = -10 m/s²      ( ∵ -ve is because of the downward motion)

Putting all the values,

s= 0 \times 8 + \frac{1}{2}(-10)8^{2} = -320 \ m ( ∵ -ve displacement means it is in downwards)

umka21 [38]

Answer:

5xyz

Step-by-step explanation:

\frac{15x^2y^3z}{3xy^2}

Step 1: Divide the numbers

\frac{15}{3}=5\\\\=\frac{5x^2y^3z}{xy^2}

Step 2: Simplify

\frac{x^2}{x}\\\\= x\\\\=\frac{5xy^3z}{y^2}

Step 3: Simplify

\frac{y^3}{y^2} = y\\\\=5xyz

Therefore, the simplified answer is =5xyz
