1. The circumference if a circle can be found by multiplying pi (n = 3.14) by the diameter of the circle.

2. If a circle has a diameter of 4, it’s circumference is 3.14*4 = 12.56.

3. If you know the radius, the diameter is twice as large.

Let u = 〈1,5〉 and v = 〈3, −2〉. Write each vector in component form and draw an arrow to represent the vector.

Answer:

a. 〈4,3〉

b. 〈-2,7〉

c. 〈11,4〉

Step-by-step explanation:

a. u + v

〈1,5〉 + 〈3, −2〉

〈1+3,5-2〉

〈4,3〉

b. u - v

〈1,5〉 - 〈3, -2〉

〈1-3,5-(-2)〉

〈-2,7〉

c. 2u + 3v

2*〈1,5〉 + 3*〈3,-2〉

〈2*1,2*5〉 + 〈3*3,3*(-2)〉

〈2,10〉 + 〈9,-6〉

〈2+9,10-6〉

〈11,4〉

To draw the vectors, let's put them on the origin (0,0), so let's draw the line until the point of its component form, with an arrow. The vectors are shown below.
