What is the ratio of the circumferences for two circles with areas 6π m2 and 150π m2?

hichkok12 [17]

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{Area_1}{Area_2}\bigg)
$

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{6 \pi }{150 \pi }\bigg)
$

$\bigg( \dfrac{Length_1}{Length_2} \bigg)^2 = \bigg( \dfrac{1 }{25}\bigg)
$

$\dfrac{Length_1}{Length_2} = \sqrt{ \dfrac{1}{25} } 
$

$\dfrac{Length_1}{Length_2} = \dfrac{1}{5}$

-------------------------------------------------------------
Answer: The ratio of the two circles = 1 :5

PLEASE HELP ASAP!!!!!!!!

Answer:

The first 5 terms are;

-2, 2, 13,38 and 91

Step-by-step explanation:

Here, we want to write the first 5 terms of the sequence.

We already have the first term as 1

Now, we need the 2nd term

Putting two in place of n, we have ;

2f(1) + 3n

= 2(-2) + 3(2) = -4 + 6 = 2

For the 3rd term, put 3 in place of n

2f(2) + 3(3)

sine f(2) = 2, we have

2(2) + 9 = 4+ 9 = 13

For the fourth term, put 4 in place of n, we have

2f(3) + 3(4)

since f(3) = 13

we have; 2(13) + 12 = 26 + 12 = 38

For the 5th term, put 5 in place of n, we have

2f(4) + 3(5)

since f(4) = 38, we have

2(38) + 15 = 76 + 15 = 91

the width of a rectangle is 7 feet less than it's length.if the area of the rectangle is 170 square feet, then find the length a

balu736 [363]

let length = x

width is 7 feet less than length

width = x-7

area = length *width

area = x(x-7)

170=x²-7x

x²-7x-170=0

x²-17x+10x-170=0

x(x-17)+10(x-17)=0

(x-17)(x+10)=0

x=17 or x=-10

since length cannot be negative so x=17

and width =x-7 =17-7=10

length =17 feet and width =10 feet
