What is the minimum value for y= 3cosx?

VashaNatasha [74]

Take the deritive
y'=-3sinx
find whre it equals 0
it equals 0 at -pi, 0, pi, etc
find whre it changes from negative to positive
at -0.5pi, the derivitive is positive
at 0.5pi, the deritivie is negative
changes from positive to negative at x=0
that means that the max values are at pi and -pi in 2pi intervals

-pi, pi, 3pi, 5pi,etc
the min y value is -3

so the minimum(s) are/is at (2aπ,-3) where 'a' is an integer

The answer is D. The temperature coefficient should be -1,5 as the temperature is dropping by the hour. Furthermore the starting temperature is 72 degrees so that should be added to the final answer. Therefore you get t = -1.5h + 72

The problem statement tells you ∠MLK is 61°, so ∠LMK = 180° -68° -61° = 51°. Since a tangent is always perpendicular to a radius, triangles LJM and LJK are right triangles.

Trigonometry tells you ...
tangent = opposite / adjacent
so you can write two relations involving LJ.
tan(51°) = LJ/JM
tan(68°) = LJ/JK
The second equation can be used to write an expression for LJ that can be substituted into the first equation.
LJ = JK*tan(68°) = 3*tan(68°)
Substituting, we have
tan(51°) = 3*tan(68°)/JM
Multiplying by JM/tan(51°), we get
JM = 3*tan(68°)/tan(51°)
JM ≈ 6.01

The radius of circle M is about 6.01.

Answer:

Graph B shows function f of x equals 4 multiplied by 3 to the power of negative x.

Step-by-step explanation:

$f(x) = 4(3)^{-x}$ is the value 4 times three raised to the negative x. Graph B is the best representation.
