Area is defined as a product of sides when we talk about squares.

$A=a\cdot a=20\cdot20=\boxed{400}$

The area of the front cover of notebook is 400 centimetres squared.

Hope this helps.

What is the answer of 7 copies of the sum of 8/5 + 4

kotykmax [81]

To solve (8/5 + 4)7, you first have to add 8/5+4. But you cannot simply add the too because they have to be in a common denominator 'form'. To do that, we find a common denominator which is 5. We then multiply 4/1 by 5.
8/5 + 4/1= 8/5 +20/5.
Now you can solve; 8+20= 28. You leave the denominator as 5.
You get 28/5 and now you have to multiply it by 7/1. Another of saying 28/5 is 5 3/5. So 5 3/5 x 7/1= 39 2/10 (final answer)

The graph of the function showing the path of a soccer ball thrown by a goalie in a video game, f(x) = –0.05x2 + 2.5x + 5.2, is

Tju [1.3M]

Answer:

The correct option is 4.

Step-by-step explanation:

The given function is

$f(x)=-0.05x^2+2.5x+5.2$

Where f(x) is height of the ball and x is the distance.

It is a polynomial function with degree 2. All polynomial functions are defined for all real numbers, therefore the mathematical domain of the function is all real numbers.

$-\infty$

Factorize the given function.

$f(x)=-0.05(x^2-50x-104)$

$f(x)=-0.05(x^2-52x+2x-104)$

$f(x)=-0.05(x(x-52)+2(x-52))$

$f(x) = -0.05 (x - 52) (x + 2)$

Put f(x)=0 to find the x intercepts.

$0 = -0.05 (x - 52) (x + 2)$

Equate each factor equal to 0.

$x=52,-2$

Therefore at x=52 and -2, the graph of f(x) intersects x-axis. Before x=-2 and after x=52 the values of f(x) is negative. Height cannot be negative, therefore reasonable domain is lie between -2 to 52.

Distance cannot be negative, therefore the reasonable domain must be positive.

$0\leq x\leq 52$

Therefore the reasonable domain is $0\leq x\leq 52$ and option 4 is correct.
