Info from question
brainly.com/question/1025208so we have
f(x)=3x-4 and
g(x)=x(2)-2
the x(2) should mean 2 times x or 2x, but if it means x^2 then
g(x)=x^2-2
solution set is represented by S={solutions}
so to see what values make them equal, we set them equal to each other
if x(2)=2x then go to AAAAAAAAAA
if x(2)=x^2 then go to BBBBBBBBBBBBB
AAAAAAAAAAAA
3x-4=2x-2
subtract 2x from boths ides
x-4=-2
add 4 to both sides
x=2
therefor the number that would satisfy the thingumy is the value of 2 so
S={2}
BBBBBBBBBB
3x-4=x^2-2
subtract (3x-4) from both sides
0=x^2-3x+2
factor
(x-2)(x-1)=0
set each to zero
x-2=0
x=2
x-1=0
x=1
so the answer is x=1 or 2 so
S={1,2}
so the answer is
if x(2)=2x then S={2}
if x(2)=x^2 then S={1,2}

Answer: ds/dt = 11</h3>
================================================
Work Shown:
Before we can use derivatives, we need to find the value of s when (x,y) = (15,20)
s^2 = x^2+y^2
s^2 = 15^2+20^2
s^2 = 225+400
s^2 = 625
s = sqrt(625)
s = 25
-----------
Now we can apply the derivative to both sides to get the following. Don't forget to use the chain rule.
s^2 = x^2 + y^2
d/dt[s^2] = d/dt[x^2 + y^2]
d/dt[s^2] = d/dt[x^2] + d/dt[y^2]
2s*ds/dt = 2x*dx/dt + 2y*dy/dt
2(25)*ds/dt = 2(15)*5 + 2(20)*(10)
50*ds/dt = 150 + 400
50*ds/dt = 550
ds/dt = 550/50
ds/dt = 11
-----------
