If a1 = 47 and d = 17, find the first 5 terms in the sequence. a
O O O
47, 64, 81, 98, 115
47, 30, 13, 4, 21
-4, -21, 13, 30,47
47,63, 80, 96, 112

first option

Step-by-step explanation:

Given a₁ = 47 and d = 17

Then to find a term in the sequence add 17 to the previous term, that is

a₁ = 47

a₂ = a₁ + 17 = 47 + 17 = 64

a₃ = a₂ + 17 = 64 + 17 = 81

a₄ = a₃ + 17 = 81 + 17 = 98

a₅ = a₄ + 17 = 98 + 17 = 115

The first 5 terms are 47, 64, 81, 98, 115

the answer is 62.8 cubic units

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
