Answer:
x = - 3
Step-by-step explanation:
To find the zero, let f(x) = 0, that is
4x + 12 = 0 ( subtract 12 from both sides )
4x = - 12 ( divide both sides by 4 )
x = - 3 ← is the zero
For what I understand, if a robot was to make 5/6 of a boat per day, in 6 days it will have made 5 boats. The answer is 5
The answer would be 32 pieces
Using the same form as above:
<span>a*1.025^t = 500. </span>
<span>a = 500/(1.025^t), where t=6 and a is the starting amount. </span>
<span>Thus: </span>
<span>a = 500/(1.025^6) = 431.148433 = 431.15$ </span>
