$\bf \textit{area of a sphere}\\\\
A=4\pi r^2\qquad \qquad \cfrac{A}{4\pi }=r^2\implies \sqrt{\cfrac{A}{4\pi }}=r$

For the function y=-3+4cos (5pi/6 (x+4)), what is the minimum value

Elena L [17]

Function y is a function of cosine transformed by some operations, so cos can take values from interval <-1;1>, which means that this function can take values from interval <-7;-1>. The minimum value is -7. The graph will be very helpuf in this task to understand.

Hey can someone answer this ASAP

Yakvenalex [24]

Answer:

csc θ = $\sqrt{85}$ /6

sec θ = $\sqrt{85}$ /7

tan θ = 6/7

Step-by-step explanation:

The first thing to do will be to compute the length of the hypotenuse using the Pythagoras theorem;

6^2 +7^2 = hypotenuse^2

hypotenuse = $\sqrt{85}$

csc θ = 1/sinθ

sinθ = opposite side/hypotenuse

= 6/ $\sqrt{85}$

csc θ = $\sqrt{85}$ /6

sec θ = 1/cosθ

cosθ = adjacent side/hypotenuse

sec θ = hypotenuse/adjacent side

= $\sqrt{85}$ /7

tan θ = Opposite side/adjacent side

= 6/7
