X2 + y2 + 42x + 38y − 47 = 0. The equation of this circle in standard form is

erastova [34]

The Standard form of the equation of circle is (x+21)² + (y+19)² = 849

<h3>What is Standard form of circle?</h3>

To transform general form to a standard form, you can use completing the square method or you can convert this equation

x² + y² + Dx + Ey + F = 0 to x² + y² + (-2h)x + (-2k)y + (h²+k²-r²) = 0

Here, Given: x² + y² + 42x + 38y − 47 = 0

Required: Find the values of h, k, and r using this formula

x² + y² + (-2h)x + (-2k)y + (h²+k²-r²) = 0

On comparing we get,

-2h = 42

h = 21

-2k = 38

k = 19

-47 = h² + k² - r²

-47 = 21² + 19² - r²

r² = 849

r = √849

Thus, the Standard form of the equation of circle is (x+21)² + (y+19)² = 849

A container holds 8 gallons of water. It begins leaking at a constant rate. After 16 minutes the container has 6 gallons of wate

tangare [24]

In that 16 minutes, the amount that leaks out is (8 - 6) = 2 gallons.

The average unit rate of the leak is

(2 gal)/(16 min) = (2/16) (gal/min) = 1/8 gal/min

= 16 fluid ounce per min

= 4/15 fl oz per second

You visit 3 different stores that sell Takis. Store X has 3 bags of Takis for $3.04. Store Y has 5 bags of Takis for $3.60. Stor

pychu [463]

store y has the better buy.

----

store x -- 3.04 ÷ 3 = $1.01 per bag

store y -- 3.60 ÷ 5 = $0.72 per bag

store z -- $0.78 per bag

store y cost the least so it is the best option.

Within the set of whole numbers , one set of numbers satisfies the recursive formula an=(an-1)^2-an-1, when a4=870 what are the

andrew11 [14]

Answer: 3 and 6 will be the first and second term of the given series respectively.

Explanation: since it is given- $a_n=(a_{n-1} )^2-a_{n-1}$ and $a_4=870$

so, by replacing n by 4, we will get- $a_4=a_3^2-a_3$ ⇒870= $a_3^2-a_3$ ⇒ $a_3^2-a_3-870=0$

after solving this equation we will get, $a_3= -29$ and 30.

If $a_3= -29$ , but it is not a whole number.

Thus, $a_3=30$ will be the value of third term of the given series.

Again, by applying the given condition $a_n=(a_{n-1} )^2-a_{n-1}$ , $a_2= 6$ or -5 (not possible), so, $a_2=6$ will be the second term.

Similarly, $a_1=3$ or -2 but we will go to the whole number.

Thus, $a_1=3$ will be the first term.
