Cot^2 135-sin210+5cos^2 225
TiliK225 [7]
\cot135^o=\cot(90^o+45^o)=-\tg45^o=-1\\\\\sin210^o=\sin(180^o+30^o)=-\sin30^o=-\dfrac{1}{2}\\\\\cos225^o=\cos(180^o+45^o)=-\cos45^o=-\dfrac{\sqrt2}{2}

\cot^2135^o-\sin210^o+5\cos^2225^o=(-1)^2-\left(-\dfrac{1}{2}\right)+5\cdot\left(-\dfrac{\sqrt2}{2}\right)^2\\\\=1+\dfrac{1}{2}+5\cdot\dfrac{1}{2}=1\dfrac{1}{2}+2\dfrac{1}{2}=4

Indicate in standard form the equation of the line passing through the given point and having the given slope
Naddik [55]
ANSWER


The equation is

y - 5x + 20 = 0


EXPLANATION

Let the equation be
y = mx + c

where
m = 5
is the slope of the line.


We substitute this value to obtain,

y = 5x + c


Since the line passes through
(4,0)
we can use this point to determine the value of c.



We substitute this point to obtain,

0 = 5(4) + c


0 = 20 + c


c =  - 20


Our equation now becomes

y = 5x - 20


We can write this in standard form as


y - 5x + 20 = 0
