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

<span>The value 28 should have been rounded to 2×101
</span>
10-(-4)
Change the subtracting sign to a adding sign and whatever is on the right side of the sign must turn into it's opposite so: 10+4= 14
14 is your answer!!!!!!!
X^13
Because you add the exponents when multiplying
Answer:
potato temperature: 175 degrees
Step-by-step explanation:
You have to read all the words.
The formula is for the difference in temperature between oven temperature and potato temperature. Your calculation of 200 degrees difference is correct. Now you need to convert that to the potato temperature by subtracting that difference from the oven temperature of 375 degrees:
oven temp - temp difference = potato temp
375 - 200 = 175 = potato temperature
