Answer:
y=-1/4x-6
It crosses the y axis at -6 and has a slope of 1/4
Line 1: y=4x-9
0=4x-9
-4x=-9
x=2,25
Line2: y=-4x+1
0=-4x+1
4x=1
x=0,25
From the graph, we can infer that the domain of the function is [0,4].
Remember that
. From the graph we can infer that
and
, so Michael drove at a rate of
.
Now, If Michel had driven 5 miles per hour faster for the entire ride, the new rate will be
. To find the new domain, we need to find the new time. since
,
.
We can conclude that the new domain will be
, or in decimal form:
Answer:
$1954
Step-by-step explanation:
Given the profit function expressed as;
y=-3x^2 + 197x –
1279
The profit is at maximum when dy/dx = 0
dy/dx = -6x + 197
0 = -6x+197
6x = 197
x = 197/6
x = 32.83
substitute 32.83 into the modeled function
y=-3x^2 + 197x –
1279
y -3(32.83)²+197(32.83) - 1279
y = -3(1,078.03)+6,467.51 - 1279
y = -3,234.09+6,467.51-1279
y = 1,954.42
hence the maximum amount of profit the company can make, to the nearest dollar is $1954
