Answer:
A
Step-by-step explanation:
Hello There!
First thing we notice is that the y intercept is at (3,0) meaning that they have some sort of fee that has a charge of 3 dollars (represented by the 3)
Because the fee is 3 dollars we can immediately eliminate answers B and C
Now we want to find the charge for each bag of Potpourri (this can be represented by the slope)
Once again we want to choose two points on the line and plug it in into the slope formula
the points are optional but i have chosen the points (1,4.5) and (2,6)
*plug it into the slope formula*
so we can conclude that the charge per bag of potpourri is $1.50 leading us to answer choice A
The complete factorisation of the polynomial given; x³ + 2x² + 4x + 8 as in the task content can be factorised and determined as; Choice D; (x+2)(x+2i)(x-2i).
<h3>What is the complete factorisation of the given polynomial; x³ + 2x² + 4x+8?</h3>
It follows from the given task content that the polynomial whose factors are to be determined by means of factorisation is; x³ + 2x² + 4x+8.
It follows from observation that one of the zeros of the polynomial expression is at; x = -2.
Consequently, one of the factors of the polynomial in discuss is; (x+2).
x³ + 2x² + 4x+8 = (x+2) (x² - 4i²)
= (x+2)(x+2i)(x-2i)
Consequently, it follows that the complete factorisation of the polynomial is; (x+2)(x+2i)(x-2i).

82, because the rest are perfect squares
Answer:
8.635 ≤ x < 8.645
Step-by-step explanation:
When a measurement is expressed to a certain precision, it can be because it was rounded to that precision. Rounding up occurs from values that are equal to or greater than 5 in the place to the right of the right-most digit.
That is, the smallest value that will round up to 8.64 is 8.635.
Rounding down occurs from values that are less than 5 in that same number place. Any value less than 8.645 will round down to 8.64.
The boundaries of values that round to 8.64 are ...
8.635 ≤ x < 8.645
