Answer:

radius = 6

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ←r is the radius

x² + y² = 36 ← is in this form

with r² = 36 ⇒ r = \sqrt{36} = 6

What are the solutions 2x^2 +7x=4
elena55 [62]
So your equation is 2x^{2} +7x = 4. You need to simplify this answer.
So first off, do 2x times 2x.
2 x 2 = 4.
Your equation is now 4x + 7x = 4.
You're already off to a great start, so now let's add 4x + 7x. It is 11x.
Your equation is almost done! It's 11x = 4 right now.
Divide both sides by 11, and your answer is...
0.36363636 and so on, or you can round to the nearest hundreth, in which it will be

0.36.

I hope I helped!

The area of a rectangle is 99 ft^2, and the length of the rectangle is 7 more than double the width. Find the dimensions of the
Sergio039 [100]

Answer:

width =5.5ft

length =18

Step-by-step explanation:

w=x

L=2x+7

area=w*L

99 = x(2x+7)

99=2x^{2} +7x

2x^{2} +7x-99=0

2x^{2} +18x-11x-99=0

2x(x+9)-11(x+9)=0

(2x-11)(x+9)=0

2x-11=0

2x=11

x=11/2

x=5.5

L=2x+7=2*5.5+7=11+7=18

Write these series with summation notation. 1,4,9,16...
maksim [4K]

Answer:  \sum\limits_{i=1}^{n} n^2 , where n is a natural number.

Step-by-step explanation:

A series can be represented in a summation or sigma notation.

Greek capital letter, ∑ (sigma), is used to represent the sum.

For example: \sum\limits_{n=1}^{\infty} n=1+2+3+4+5+..., where n is a natural number.

The given series : 1,4,9,16 which can be written as 1^2, 2^2, 3^2,... .

So , we can write it as

\sum\limits_{n=1}^{\infty} n^2 , where n is a natural number.
