1 answer:
Answer:
( About ) 1,099 pounds
Step-by-step explanation:
The force required to keep this truck from rolling down the hill is opposed by the force of friction, comparative to the 2600 pounds of force against this friction. It should be that this opposing force is at work more towards the bottom of this hill, and thus the question asks the magnitude of latter force to keep this truck idle -
|| F || = sin( 25 ) * ( Fg ) = sin( 25 ) * ( 2600 lb ) = ( About ) 1098.80748 pounds
<u><em>This can be rounded to a solution of 1099 pounds</em></u>

Step 1
Let
x------> the cost in dollar
y-----> the pounds of grapes
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or
The line in the graph represent a direct variation
Find the constant of proportionality k
------> substitute point B ----->
The slope is equal to the constant of proportionality
so
the linear equation is
therefore
<u>the answer Part a) is</u>
For every dollar you spend, you can get pounds
Step 2
Find the cost for one pound of grapes
Let
substitute the value of g in the linear equation and solve for c
therefore
<u>the answer Part b) is</u>
For each pound of grapes, you would need
