The entire shipment contains 9 2/7 tons of sugar
Step-by-step explanation:
- Step 1: Find the total amount of sugar in the entire shipment.
Number of containers in the shipment = 4 1/3 = 13/3
Number of tons of sugar = 2 1/7 = 15/7
⇒ Total amount of sugar = 13/3 × 15/7 = 65/7 = 9 2/7 tons
<em><u>Question:</u></em>
<em>Mrs. Magdalino kept records on how much she spent on gasoline and the maintenance of her car. She found that it cost $485 to drive 500 mi in a month.</em>
<em>a) Find the cost per mile. Write an equation that relates the cost c for gasoline and maintenance of a car to the number of miles m the car is driven.</em>
<em>b) Use the equation to find the cost for driving 1200 miles.</em>
<em>c) About how many miles are driven for a cost of $820?</em>
<em><u>Answer:</u></em>
a)
$485/500mi = <u><em>$0.97/mi</em></u>
c = cost
m = miles driven
cost per miles driven = cost / mile driven = <u><em>c/m</em></u>
b)
(1200 mi)*($0.97/mi) = <u><em>$1164</em></u>
c)
(x miles)*($0.97/mi) = $820
*divide both sides by $0.97/mi
x miles = $820/($0.97/mi)
<u><em>x = 845.36 miles</em></u>

In this question, we have to identify the zeros of the polynomial, along with a point, and then we get that the formula for the polynomial is:
------------------------
Equation of a polynomial, according to it's zeros:
Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.
------------------------
Identifying the zeros:
Given the graph, the zeros are the points where the graph crosses the x-axis. In this question, they are:
Thus
------------------------
Leading coefficient:
Passes through point (2,-8), that is, when 
, which is used to find a. So
------------------------
Considering the zeros and the leading coefficient, the formula is:
