If sec a = 5/4 and a is an angle in quadrant iv find the value of cos a
wariber [46]
We know that
<span>sec a = 5/4
</span>sec(a)=1/cos(a)
then 
cos (a)=1/sec(a)
cos (a)=1/(5/4)=4/5---> is positive because the function cos is positive in IV quadrant

the answer is cos(a)=4/5

Find the slope and the equation of the line tangent to f (x )equals StartFraction 2 x minus 1 Over x plus 7 EndFraction at x​ =
kondor19780726 [428]

Answer:

y=\frac{5}{27} x-\frac{1}{27}

Step-by-step explanation:

f(x)=\frac{2x-1}{x+7}

To find slope of f(x) at x=2, find the derivative f'(x)

apply quotient rule to find derivative

f(x)=\frac{2x-1}{x+7}\\f'(x)=\frac{2(x+7)-1(2x-1)}{(x+7)^2} \\f'(x)=\frac{15}{(x+7)^2}

f'(x) is the slope . Now find slope at x=2. plug in 2 for x

f'(x)=\frac{15}{(x+7)^2}\\f'(2)=\frac{15}{(2+7)^2}=\frac{5}{27}

find out f(x) when x=2

f(x)=\frac{2x-1}{x+7}\\f(2)=\frac{2(2)-1}{2+7}=\frac{1}{3}

Now frame the equation of the line

(2,1/3) slope = 5/27

y-y_1=m(x-x_1)\\y-\frac{1}{3}=\frac{5}{27} (x-2)\\y-\frac{1}{3}=\frac{5}{27} x-\frac{10}{27}\\\\y=\frac{5}{27} x-\frac{1}{27}\\\\
