For this case we must find the area of the cookie, knowing that it has a circular shape. By definition, the area of a circle is given by:

A = \pi * r ^ 2

Where:

r: It is the radius of the circle

According to the data we have:

r = \frac {2} {2} = 1 \ in

Thus, the area of the cookie is:

A = \pi * (1) ^ 1

We have \pi = 3.14

A = 3.14 * 1\\A = 3.14

We round:

A = 3.1

Thus, the area of the cookie is 3.1 \ in ^ 2

Answer:

3.1 \ in ^ 2

Which is the rationalized form of the expression sqrtx/sqrtx+sqrt7
ArbitrLikvidat [17]

Answer:

(x - √7*√x) / (x - 7)

Step-by-step explanation:

I suppose your expression is √x / (√x + √7)

(√x * (√x - √7)) / ((√x + √7) * √x - √7)) = (√x * √x - √7 * √x) / (x - 7)

= (x - √7*√x) / (x - 7)

What is the sum of the expression ? (9 c − 8 d ) + ( 2 c − 6 ) + ( − d + 3 )
Dmitrij [34]

Answer:

12c - 9d + 3

Step-by-step explanation:

(9 c − 8 d ) + ( 2 c − 6 ) + ( − d + 3 )

Combine like terms ( the d's with the d's, the c's with the c's and the numbers without the variables with the number w.out the variables)

9c - 8d + 3c - 6 - d + 3

12c - 9d + 3

That is at it's simplest form

Hope this helped!

have a supercalifragilisticexpialdocious day!

What is a1 for the geometric sequence for which a8= -3584 and a3 = 112 ?
Kazeer [188]

Answer:

The first term is 28.

Step-by-step explanation:

Given: 8th term of Geometric sequence , a_8=-3584

and 3rd term of Geometric Sequence, a_3=112

We have to find First term of given geometric Sequence.

Let a be the first term of geometric sequence.

We know that,

a_n=ar^{n-1}

So,

\frac{a_8}{a_3}=\frac{ar^{8-1}}{ar^{3-1}}=\frac{-3584}{112}

\frac{r^{7}}{r^{2}}=-32

r^5=-32

r=-2

So, 3rd term = 112

a × (-2)² = 112

a = 112 / 4

a = 28

Therefore, The first term is 28.
