Answer:
Step-by-step explanation:
If y = 2x + 1, then dy/dt = 2(dx/dt).
If y = 2x + 1, then y = 2(40) + 1 when 40 is substituted for x. y = 81.
(a) if dx/dt = 3, find dy/dt when x = 4:
Replacing dx/dt with 3 in dy/dt = 2(dx/dt) yields dy/dt = 2(3) = 6.
(b) if dy/dt = 2, find dx/dt when x = 40:
Replacing dy/dt with 2 in dy/dt = 2(dx/dt) results in 2 = 2(dx/dt), so dx/dt must be 1.
Answer:
1150 because 400 + 394 + 388 = 1182 - 32 = 1150.
For x,
(32+x)/2=14
32+x=14*2
32+x=28
x=28-32
x=-4
For y,
(40+y)/2=26
40+y=26*2
40+y=52
y=52-40
y=12
Therefore coordinates of B(-4,12)
