What two numbers multiply to -320 and add to 32
iragen [17]
Let a and b be the numbers,then a+b=32,b=32-a
ab=-320
a(32-a)=-320
32a-a^2=-320
a^2-32a-320=0
a^2-40a+8a-320=0
a(a-40)+8(a-40)=0
(a-40)(a+8)=0
a=40 or-8
when a=40,b=32-40=-8
when a=-8,b=32-(-8)=32+8=40
so numbers are 40 and -8

The triangular numbers are defined by the recursive formula t1 = 1, tn = tn - 1 + n, where n ∈N and n &gt; 1. What are the first
GalinKa [24]

ANSWER

C) 1, 3, 6, 10, 15, 21, 28, 36, 45

EXPLANATION

The recursive formula is,

t_1=1,t_n=t_{n-1}+n

when n is a natural number greater than 1.

When n=2,

t_2=t_{2-1}+2

t_2=t_{1}+2 = 1 + 2 = 3

when n=3,

t_3=t_{2}+2 = 3 + 3= 6

when t=4,

t_4=t_{3}+2 = 6+ 4= 10

When t=5,

t_5=t_{4}+5 = 10 + 5 = 15

when t=6,.

t_6=t_{5}+6 = 15 + 6 = 21

when t=7

t_7=t_{6}+7 = 21 + 7 = 28

When t=8,

t_8=t_{7}+8 = 28 + 8 = 36

When t=9,

t_9=t_{8}+9 = 36 + 9 = 45

Hence the first nine triangular number are

C) 1, 3, 6, 10, 15, 21, 28, 36, 45
