Answer:

(x - 7)² + (y + 2)² = (2√13)²

Step-by-step explanation:

We already know that the center is at (7, -2), but must find the radius.  The radius is the distance between the points (7, -2) and (1, -6):

r = √ [6² + 4²] ) = √(36 + 16) = √52 = √4√13 = 2√13.

Then the desired equation is (x - 7)² + (y + 2)² = (2√13)²

Dried rose petals can be used to make rose water. Fatima buys 0.454 kilogram
Vesnalui [34]

Fatima's claim that she has 0.413 kilogram of rose petals left is wrong

<h3>How to determine the amount of rose petals left?</h3>

The given parameters are:

  • Amount purchased = 0.454 kg and 0.056 kg
  • Used amounts = 0.02kg and 0.095 kg

The amount left is the difference between the amount purchased and the amount used.

So, we have:

Remaining  = 0.454 + 0.056 - 0.02 - 0.095

Evaluate

Remaining  = 0.395

This means that the remaining amount is 0.395kg, not 0.413 kg

Hence, Fatima's claim that she has 0.413 kilogram of rose petals left is wrong

Please help i need this
Svet_ta [14]

Slope Formula - (y² - y¹) / (x² - x¹)

(1, 7)

x¹ = 1

y¹ = 7

(-4, -8)

x² = -4

y² = -8

-8 - 7 = -15

-4 - 1 = -5

Simplify - -15/-5

-15/5 = -3

Your answer is -3.

Hope this Helps!!
