Answer:

9\pix^{4}

Step-by-step explanation:

A monomial is an algebraic expression with one term.

So that,

area of a circle = \pir^{2}

if r = 3x^{2}, then;

area of the circle = \pi x (3x^{2} )^{2}

                            = \pi x 9x^{4}

                            = 9\pix^{4}

The area of the circle is 9\pix^{4} square units.

Therefore, the monomial the represent the number of square units in the area of the circle is 9\pix^{4} square units.

At the start of the week a bookshop had science and art books in the ratio 2:5. By the end of the week, 20% of each type of book
Anastaziya [24]
Let there be 2x science and 5x art books 
<span>science books sold = 2x × 0.2 = 0.4x </span>
<span>science books unsold = 2x – 0.4x = 1.6x </span>

<span>art books sold = 5x × 0.2 = x </span>
<span>art books unsold = 5x – x = 4x </span>

<span>total books unsold = 1.6x + 4x = 5.6x </span>
<span>5.6x = 2240 </span>
<span>x = 400 </span>

<span>2x science = 800 </span>
<span>and 5x art books = 2000 </span>

What is the slope between the points 5,-1 and -2,-3?
pishuonlain [190]
To find slope, use the equation (y2-y1)/(x2-x1). In your case, the equation is going to look like (-3 - -1)/(5 - -2) or (-3 +1)/(5 + 2), and that simplifies to -2/7.
