At what point is the following function continuous?
liubo4ka [24]

Check the picture below.

something worth noticing           \bf \cfrac{x^2-x-6}{x-3}\implies \cfrac{(\underline{x-3})(x+2)}{\underline{x-3}}\implies x+2

so, we're really graphing x+2, with a hole at x = 3, however, when x = 3, we know that f(x) = 5, but but but, when x = 3, x+2 = 5, so we end up with a continuous line all the way, x ∈ ℝ, because the "hole" from the first subfunction, gets closed off by the second subfunction in the piece-wise.

-Dominant- [34]

Answer:

94°

Step-by-step explanation:

Bisect means to divide any thing into any two equal parts.

So here,

<h3 />

We see that Line RP bisects NRQ and NRP is 47°

So as we know that a bisector divides anything into two parts so the other angle that is PRQ will also be 47°

<h3>So we know ,</h3>

Angle NRQ = Angle NRP + PRQ

Let angle NRQ be x

<h2>According to the question </h2>

= x = 47 + 47

=  > x = 94

Answer - The measure of Angle NRQ is 94°

Hope it helps you!!

find the value of $x$ for which $x$ degrees fahrenheit is exactly the same as $x$ degrees celsius (remember the formula for conv
Dafna11 [192]

The value of temperature for which both degrees Fahrenheit and degrees Celsius are the same is -40.

  • Temperature is a numerical expression of how hot a substance or radiation is. The term "temperature" describes how hot or cold a body is. It is, specifically, a method of calculating the kinetic energy of the particles that make up an item. When particles travel more quickly, the temperature rises, and vice versa. Nearly every aspect of our daily life and all scientific fields are significantly influenced by temperature.
  • Let C denote the temperature in Celsius.
  • Let F denote the temperature in Fahrenheit.
  • We understand the relationship between the temperature units, Celsius and Fahrenheit.
  • F = (9/5)C + 32
  • For F=C
  • F = (9/5) F + 32
  • 5F = 9F + 160
  • 4F =-160
  • F =-40
  • C =-40
