Write the ratio of circles to triangles. The shapes are of two types of shapes: circles and triangles. The part-to-part ratio of circles to triangles is the number of circles compared to the number of triangles.

In this exercise, lines m and n are parallel. Find the measure of each numbered angle.

A wire of length \( 7 x \) is bent into the shape of a circle. A. Express the circumference of the circle as a function of \( x \). B. Express the area of the circle as a function of \( x \). A. \( C(x)=\square \)

The diameter of a circle measures 20 ft. What is the circumference of the circle?Use 3.14 for π, and do not round your answer. Be sure to include the correct unit in your answer.

1. Найдите координаты вектора \( \overrightarrow{K P} \), если известны координаты точек \( \mathrm{K}(-3 ; 7), \mathrm{P}(2 ; 4) \)

2) Dato un punto \( P(-2 ;-1) \) e una rette II \( y=2 x-3 \) deterninare retto per il punto \( P \) ! Fare grefico
