Step-by-step explanation:
Answer:24r+48h= $1248
Step-by-step explanation:
24*36+48*8
864 + 384 = 1248
Not sure if it's correct I'm not brilliant with equations xx
If there is such a scalar function <em>f</em>, then



Integrate both sides of the first equation with respect to <em>x</em> :

Differentiate both sides with respect to <em>y</em> :


Integrate both sides with respect to <em>y</em> :

Plug this into the equation above with <em>f</em> , then differentiate both sides with respect to <em>z</em> :



Integrate both sides with respect to <em>z</em> :

So we end up with

R(t) = 4t
A(r) = π(r^2)
a) A(t) = A[r(t)] = π[r(t)]^2 = π[4t]^2 = 16π(t^2)
b) t = 4,
A(4) = 16*3.14*(16)^2 = 12,861.44
Answer:
Step-by-step explanation:
slope of required line=5
point is (-1,0)
reqd. eq. of line is
y-0=5(x-(-1))
y=5(x+1)
y=5x+5
