Answer:
Step-by-step explanation:
Given that,
Center = (2,-9)
Radius of the circle, r = 7
We need to find the equation of a circle with a center at (2, -9) and a radius of 7. It can be given by :
Put h = 2, k = -9 and r = 7 So,
Hence, this is the required solution.
<em>Answer,</em>
<em>1) -2</em>
<em>2) 3/b (Reciprical means flipping the fraction) </em>
<em>3) -5 for number (Question 11) </em>
<em>4) Number 12 I couldn't tell if the sign was a dividing sign or a plus sign. </em>
<em>5) I'm not very good with word problems so, I won't be much help. But, I think they want you to subtract the highest temperature from the lowest. </em>
5 + 4 - 1 = 7
7 + 4 - 1 = 10
10 + 4 - 1 = 13
And so on
Well, a logarithmic expression is just an exponential expression written from the point of the exponent.
now, ln is just a shorthand for the logarithm with a base "e" or euler's constant, so-called the "natural logarithm", now, let's use the exponential version of that here, and let's say equals an constant exponent of "k",
now, look closely, what "k" value, what exponent, negative or fraction or positive, will ever make "e" to 0? none, so one can say is "undefined".
