Please help! Let f be the function given by f(x)= 4 sin(x)+4 cos(x). As shown
in the figure to the right, the graph crosses the y-axis at point P and the
x-axis at point Q.
P(94)
a. Write an equation for the horizontal tangent to f(x).
Justify your
answer.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
