Sean los siguientes vectores: A=-3 i + -1 j

B=3 i + 2 j

Halle el ángulo que forman utilizando la siguiente ecuación :A⃗ ∙B⃗ =ABcosθ. (Sugerencia: Calcule el producto punto, luego calcule la magnitud de cada vector y, por último, utilice la operación del Arco coseno para hallar el ángulo)

Five dinosaurs go for a walk and come across some lovely chicken wings. their names are rexy, bronto, steggy, paly, and terry. there are exactly 5 dozen wings(equal enough for each dino to have a dozen right? ); however, terry is on a diet and he only eats 6 wings. if paly eats 2 more than terry, steggy eats 4 more than paly, and bronto and rexy eat the same amount because they are really hungry from not eating all day, how many chicken wings did each dino eat?

Which of the expressions (on the photo document i inserted) together represent all solutions to the following equation? 8cos(12x)+4=-4 *the answer should be in degrees.* > i would like for someone to explain the process to find the solutions for this.

For f(x) = 3x+1 and g(x) = x2 - 6, find (g/f)(x)
