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)

step-by-step explanation: step 3 should really go to step seven, but anyway never mind.

1 ∠oln ≅ ∠lno

d) 48

i dont know the answer but here's a picture of a dog

answer: hence, function will be

explanation:

since we have given that

cost of a new textbook = $85

according to question, the resale value of a textbook decreases by 25% with each previous owner,

so, our function becomes,

here, y is the total value of the text book after x owners.

hence, function will be
