Answer 2

I can help you with your math question. The scalar product of two vectors $\vec{x}$ and $\vec{y}$ is defined as $\vec{x} \cdot \vec{y} = |\vec{x}| |\vec{y}| \cos \theta$, where $\theta$ is the angle between the vectors. To find the scalar product of the vectors $\vec{x}(1; -3)$ and $\vec{y}(-2; 5)$, we can use the formula $\vec{x} \cdot \vec{y} = x_1 y_1 + x_2 y_2$, where $x_1, x_2$ are the components of $\vec{x}$ and $y_1, y_2$ are the components of $\vec{y}$. Plugging in the values, we get $\vec{x} \cdot \vec{y} = (1)(-2) + (-3)(5) = -2 - 15 = -17$. Therefore, the scalar product of the vectors is -17. I hope this helps. If you have any other questions, feel free to ask me.Ответь+подробно.++Знайдіть+скалятрий+добуток+векторів+х(1;+-3)+і+у(-2;+5)​+
