Find a cubic polynomial whose zeros are 1/2,1 and -3.
Alexxx [7]

Answer:

2x³+3x²-8x+3

Step-by-step explanation:

So we know x=½,x=1 and x=-3

Then (2x-1)(x-1)(x+3) are the factors

(2x-1)[(x²+3x-x-3)]

(2x-1)[(x²+2x-3)]

2x³+4x²-6x-x²-2x+3

2x³+3x²-8x+3

HELP!
PSYCHO15rus [73]

Answer:

74676.

Step-by-step explanation:

Lets try multiplying 127 by 294 ( 127 is a prime number):

127 * 294 = 37338.

37338 / 196 = 190.5

37338 * 2 = 74676  which will now be divisible by 196.

74676 will be divisible by 98, 49 and 7 (because they are factors of  196).

It is also divisible by 84 ( to give 889) and therefore by 42, 28, 21, 14, 12,  6, 4, 3 , 2 and 1 which are all factors of 84.

A cable company uses the formula S = 20,000 (1 + 0.08)y to estimate the number
vlada-n [284]

Answer:

C. Every year the number of subscribers is estimated to increase by 8% over the

number of subscribers the year before.

Step-by-step explanation:

Using the formula :

S = 20,000 (1 + 0.08)^y to estimate ;

S = number of subscribers ; y = years

The expression : (1 + 0.08)^y

0.08 = 0.08 * 100% = 8%

(1 + 0.08)^y represents a continous growth or increase in the number of subcsribers by 8% over the number of subscribers the preceeding year
