Answer:

Just substitue every 't' with -4

Step-by-step explanation:

g(-4) = 3*(-4)*(-4) + 2*(-4) + 1

g(-4) = 64-8+1

g(-4) = 57

Answer:

<u>g</u><u>(</u><u>-</u><u>4</u><u>)</u><u> </u><u>is</u><u> </u><u>4</u><u>1</u>

Step-by-step explanation:

g(t) = 3 {t}^{2}  + 2t + 1

when t is -4, substitute -4 in place of t:

g( - 4) = 3 {( - 4)}^{2}  + 2( - 4) + 1 \\ g( - 4) = 48 - 8 + 1 \\ g( - 4) = 41

Let u = 〈1,5〉 and v = 〈3, −2〉. Write each vector in component form and draw an arrow to represent the vector.
Alexxx [7]

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.
