(
Step-by-step explanation:
(-7°C)-(-4°C)
-7°C + 4°C
-3°C
Answer:
x-intercept:
A line that crosses the graph at x-axis.
i.e substitute y = 0 and solve for x.
As per the statement:
A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsius, and the number of insect larvae (y) in the water
Given the graph:
Substitute y = 0 we have;
⇒
⇒
⇒
⇒
⇒
By zero product property we have;
x-20 =0 and x+10 = 0
⇒x = 20 and x = -10
Therefore, the x-intercept represents the water has no larvae at −10 degrees Celsius and 20 degrees Celsius.
Answer:
break even point = 8000 socks produced or $36000 in costs
Step-by-step explanation:
the cost function of the firm is
total cost = fixed cost + variable cost = $20000 + $2*Q
where Q= number of socks
the revenue from sales is
sales = Price* Q = $4.50*Q
the break even point is reached when the net profit is = 0 ( that is, the total cost is equal to the revenue from sales) , then
total cost = sales
$20000 + $2*Q =$4.50*Q
Q= $20000/($4.50-$2) = 8000 socks
that represents
total cost = $20000 + $2*8000 = $36000
then
break even point = 8000 socks produced or $36000 in costs
