For this, the first thing to do is to assume that the function of temperature with respect to r is written in one of the following ways:
Way 1:
Way 2:
To find the instant variation we must find the derivative of the temperature with respect to the distance r.
We have then:
For function 1:
Rewriting
For function 2:
Rewriting
Answer:
The instantaneous variation of the temperature with respect to r is given by:
Assuming function 1:
Assuming Function 2:
Answer:
f(-2) = 3
Step-by-step explanation:
Look at the graph when x = -2, f(-2) = 3
Answer:
y=-3/2x-2
Step-by-step explanation:
first, we must calculate the slope (m) using the equation (y2-y1)/(x2-x1)
here are the given points: (0,-2) and (-4,4)
we can label the points:
x1=0
y1=-2
x2=-4
y2=4
now substitute into the equation:
m=(4--2)/(-4-0)
m=(4+2)/-4
m=6/-4
m=3/-2
m=-3/2
the slope of the line is -3/2
now use the point-slope form, which is y-y1=m(x-x1)
substitute the given numbers into the equation
y--2=-3/2(x-0)
do distributive prop.
y+2=-3/2x
subtract 2 from both sides
y=-3/2x-2
<span>So we want to know how many individual heels did the shoemaker bought if he bought 30 pairs of heels. So to get to the answer we must know that one pair of heels is equal to two individual heels. So now we can calculate the individual number of heels: 30 pairs * 2 = 60 individual heels. </span>
