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:

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
