You plug in 7 for every x that there is.
24(7)-7=161
5((7)^2)-5+15=255
2(7+2)+2(7)=32
Answer:
dz / dt = -50
Step-by-step explanation:
To solve the chain rule must apply, we have all the necessary values to make the calculation, as follows:
using the chain rule, we find:
dz / dt = (∂z / ∂x) * (∂x / ∂t) + (∂z / ∂y) * (∂y / ∂t)
Evaluating when t = 9, we have to:
fx (6, 4) * g '(9) + fy (6, 4) * h '(9)
We know that g '(9) = −6; h '(9) = 4; fx (6, 4) = 9; fy (6, 4) = 1
Replacing:
(9 * -6) + (1 * 4) = -50
Por lo tanto dz / dt = -50
Answer:
The y intercept of Function A is greater than the y intercept of Function B.
Step-by-step explanation:
-3 is greater than -4.
Simplify both sides then isolate the variable and it gives you y=3.6
