I need help I watch anime though but fr I need help thx
Vilka [71]

Answer:

Step-by-step explanation:

In this question we have to find the expression for the value of temperature in terms of degrees Celsius.

Since, the given expression is,

F = 1.8C + 32

F - 32 = 1.8C + 32 - 32

F - 32 = 1.8C

\frac{F-32}{1.8}=\frac{1.8C}{1.8}

\frac{F-32}{1.8}=C

For F = C,

\frac{C-32}{1.8}=C

C - 32 = 1.8C

C - 1.8C = 32

-0.8C = 32

C = -\frac{32}{0.8}

C = -40

Therefore, at (-40°C) degrees of temperature degrees Fahrenheit and degrees Celsius are equal.

Find theta between 0 and 2pi of the point (2,-4). Round to the nearest hundredth.
Irina18 [472]

check the picture below.


\bf (\stackrel{x}{2}~,~\stackrel{y}{-4})\qquad tan(\theta )=\cfrac{y}{x}\implies tan(\theta )=\cfrac{-4}{2}\implies tan(\theta )=-2\\\\\\\measuredangle \theta =tan^{-1}(-2)\implies \measuredangle \theta \approx -63.44^o\implies \measuredangle \theta \approx \stackrel{360^o-63.44^o}{296.56^o}


as you may already know, tan⁻¹ function has a range of (π/2, -π/2), and therefore it will give us the negative counterpart angle, however, the positive one we can get it by going the other way, 360 - θ.
