We can see that there are 5 CDs, each of radius 9 cm
<u>Area occupied by 1 disc:</u>
Area of a circle = πr²
Area of disc = π(9)²
Area of disc = 3.14 * 81 = 254 cm²
<u>Area occupied by 5 discs:</u>
Area occupied by 5 discs = Area occupied by 1 disc * 5
Area occupied by 5 discs = 254 * 5
Area occupied by 5 discs = 1270 cm²
It’s 6w than less than symbol negative 21
1. D
Y=x+4.
That’s the answer
Answer:
<h2>-223,948</h2>
Step-by-step explanation:
The formula of a sum of terms of a gometric sequence:

a₁ - first term
r - common ratio
We have

Calculate a₁. Put n = 1:

Calculate the common ratio:


K(x)=moles
p(x)=rollls
subsitute k(x) for x in p(x)
p(k(x))=2(x-1)+3=2x-2+3=2x+1
that is
p(x)=2x+1 for
p(x)=rolls
and x is toes
